Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.

The energy harvesting module 400 for the smart watch 1 according to an embodiment of the invention is described in detail below with reference to fig. 1-10.

As shown in fig. 3 to 9, the energy harvesting module 400 for the smart watch 1 according to an embodiment of the invention comprises: a transmission 40, a base plate portion 51, a power input assembly 50, a power generation assembly 60, and an energy storage assembly. Wherein the power input assembly 50 is coupled to the transmission 40 to transmit kinetic energy to the transmission 40.

Specifically, the substrate portion 51 may be used to mount various components of the power input assembly 50. The power input assembly 50 includes a weight assembly 52 and a weight bull wheel 53. The weight assembly 52 is pivotally mounted on the base plate 51 by a pivot shaft 54 and the center of gravity of the weight assembly 52 is offset from the central axis of the pivot shaft 54, so that when the smart watch 1 shakes, the weight assembly 52 can swing or rotate around the central axis of the pivot shaft 54. The weight wheel 53 may be fixedly installed on the pivot shaft 54, whereby the weight wheel 53 and the pivot shaft 54 may be constructed to move together as a unit. It should be noted that the weight wheel 53 can be detachably connected to the pivot shaft 54 by a fastener, so as to facilitate the maintenance and replacement of the weight wheel 53; of course, the weight wheel 53 can be formed integrally with the pivot shaft 54, so that the number of components of the energy collecting module 400 can be reduced, and the assembly process can be simplified. The weight wheel 53 can be connected to the transmission 40, so that the kinetic energy collected by the power input assembly 50 can be transmitted to the transmission 40.

The power generation module 60 may be provided on the base plate portion 51, whereby the structure of the smart watch 1 can be made more rational and compact. The power generation assembly 60 is coupled to the transmission 40 to convert kinetic energy transferred from the power input assembly 50 to the transmission 40 into electrical energy. Therefore, the collection and the conversion of energy can be realized, and the purpose of self-generating electricity is achieved. The energy storage assembly may be electrically connected to the power generation assembly 60, thereby facilitating storage of electrical energy generated by the power generation assembly 60 within the energy storage assembly.

As shown in fig. 3 and 4, the weight assembly 52 of the power input assembly 50 rotates or swings under the action of an external force and is transmitted to the power generation assembly 60 through the transmission device 40, and the power generation assembly 60 can convert the kinetic energy of the transmission device 40 into electric energy and store the electric energy through the energy storage assembly to supply power to the smart watch 1.

According to the energy collection module 400 for the smart watch 1 of the embodiment of the invention, by utilizing the swing or rotation generated by the weight assembly 52 with the offset center of gravity and transmitting the kinetic energy generated by the weight assembly 52 to the power generation assembly 60 through the transmission device 40, the power generation assembly 60 converts the kinetic energy into electric energy and stores the electric energy through the energy storage assembly to supply power to the smart watch 1, so that the smart watch 1 can achieve the self-generating effect.

According to some embodiments of the present invention, the transmission device 40 may comprise multiple gear assemblies 41, the multiple gear assemblies 41 being connected in series and there being at least one pair of adjacent two-stage gear assemblies 41 with a gear ratio less than one. It should be noted that, as can be seen from the formula of the transmission ratio (the ratio of the rotation speed of the driving wheel divided by the rotation speed of the driven wheel is the reciprocal of the reference circle diameter), the transmission ratio of at least one pair of adjacent two-stage gear transmission assemblies 41 is smaller than one, and when the rotation speed of the driving gear transmission assembly 41 is a fixed value, the rotation speed of the driven gear transmission assembly 41 is greater than the rotation speed of the driving gear transmission assembly 41. Therefore, the rotation speed of the gear transmission assembly 41 can be effectively increased by arranging the multi-stage gear transmission assembly 41, so that the electric energy generated by the power generation assembly 60 can be increased, and the power generation amount can be increased. In addition, gear transmission has the advantage of compact structure, long-lived and drive ratio high, not only can make the compact structure of intelligent wrist-watch 1, improves the life of intelligent wrist-watch 1 from this, can also utilize higher drive ratio to improve the kinetic energy of transmitting to electricity generation subassembly 60, improves the generated energy.

According to one embodiment of the present invention, the multi-stage gear transmission assembly 41 may include: a first gear assembly 411 and a second gear assembly 412. For example, as shown in fig. 6, the first gear assembly 411 is a driving gear assembly, the second gear assembly 412 is a driven gear assembly, the first gear assembly 411 transmits kinetic energy to the second gear assembly 412, and the transmission ratio between the first gear assembly 411 and the second gear assembly 412 is less than one, i.e. the rotation speed of the second gear assembly 412 is greater than that of the first gear assembly 411.

Wherein the first gear assembly 411 is engaged with the second gear assembly 412. It should be noted that the first gear assembly 411 may be directly engaged with the second gear assembly 412, as shown in fig. 6. Of course, the multi-stage gear assembly 41 may further include a third gear assembly, wherein the first gear assembly 411 transfers the kinetic energy to the second gear assembly 412 through the third gear assembly, and in this case, the first gear assembly 411 is indirectly engaged with the second gear assembly 412. Further, the multi-stage gear transmission assembly 41 may not be limited to two and three gear transmission assemblies, and may be four or more multi-stage gear transmission assemblies 41.

As shown in fig. 6, the first gear assembly 411 may include a first small gear 4111 and a first large gear 4112 fixed coaxially with the first small gear 4111, so that the first small gear 4111 and the first large gear 4112 can maintain coaxial rotation speed during rotation. It will be appreciated that the first pinion gear 4111 may have a smaller pitch diameter than the first bull gear 4112, thereby facilitating kinetic energy transfer between the multiple stage gear assembly 41. In addition, the first small gear 4111 and the first large gear 4112 may be fixed together by riveting to rotate coaxially, or may be connected together by other connection methods to rotate coaxially. The first pinion 4111 can mesh with the weight bull wheel 53, thereby facilitating the transmission of the kinetic energy of the weight bull wheel 53 to the first gear assembly 411. Here, the pitch circle diameter of the first pinion 4111 may be smaller than or equal to the pitch circle diameter of the weight sheave 53, whereby the linear velocity of the first pinion 4111 can be increased.

For example, as shown in fig. 6, the first gear assembly 411 may include a first small gear 4111 and a first large gear 4112, the first small gear 4111 and the first large gear 4112 may be riveted, and the first small gear 4111 meshes with the weight wheel 53, in which case, the first small gear 4111 and the weight wheel 53 have the same linear velocity, and the first small gear 4111 and the second large gear 4122 have the same rotational velocity, that is, the linear velocity of the first large gear 4112 is greater than that of the first small gear 4111. Thereby, the linear velocity of the first large gear 4112 can be raised.

As shown in fig. 6, the second gear assembly 412 may include a second pinion gear 4121 and a second bull gear 4122 coaxially fixed with the second pinion gear 4121, whereby the second pinion gear 4121 and the second bull gear 4122 may maintain coaxial rotational speeds during rotation. It will be appreciated that the pitch circle diameter of the second pinion gear 4121 may be smaller than the pitch circle diameter of the second bull gear 4122, thereby facilitating kinetic energy transfer between the multiple stage gear assembly 41. The second small gear 4121 is engaged with the first large gear 4112 and the reference circle diameter of the second small gear 4121 is smaller than that of the first large gear 4112, thereby facilitating the transfer of kinetic energy between the multistage gear transmission assembly 41. It will be appreciated that the pitch diameter of the second pinion gear 4121 may be smaller than the pitch diameter of the first bull gear 4112, thereby not only facilitating the transfer of kinetic energy between the multiple stage gear assembly 41, but also effectively increasing the rotational speed of the second pinion gear 4121.

It should be noted that the second small gear 4121 and the first large gear 4112 may be directly engaged or indirectly engaged. For example, as shown in fig. 6, the second small gear 4121 and the first large gear 4112 may be directly engaged for kinetic energy transfer. Of course, the multi-stage gear assembly 41 may also include a third gear assembly, in which case the second small gear 4121 is indirectly engaged with the first large gear 4112 via the third gear assembly. Further, the second gearwheel 4122 is adapted to mesh with the input gear 61 of the power generation assembly 60, so that the kinetic energy of the gear transmission assembly 41 can be transmitted to the power generation assembly 60, and the input gear 61 of the power generation assembly 60 is driven to rotate to generate power. Here, the pitch circle diameter of the input gear 61 is smaller than or equal to the pitch circle diameter of the second large gear 4122, whereby the rotational speed of the input gear 61 can be further increased, and the amount of power generation of the power generation module 60 can be increased.

In some embodiments of the present invention, the substrate part 51 may include a main substrate 511 and an upper plate 512. Wherein, the main substrate 511 may be provided with a mounting hole 5112, one end of the pivot shaft 54 may be mounted in the mounting hole 5112 through the first bearing 5111, and the other end may be connected to the weight assembly 52 and the weight bull wheel 53. Thereby, the weight assembly 52 and the weight sheave 53 can be mounted on the main base 511 through the pivot shaft 54. Further, one end of the pivot shaft 54 may be provided with a stopper ring 55 and a collar 56, and the first bearing 5111 is sandwiched between the stopper ring 55 and the collar 56. Thereby, the first bearing 5111 can be installed and limited in the installation hole 5112, and the normal operation of the bearing is ensured. Further, the first bearing 5111 may be a ball bearing, whereby the production cost may be reduced.

For example, as shown in fig. 7, a mounting hole 5112 may be formed at the center of the primary base plate 511, and two first bearings 5111 may be mounted in the mounting hole 5112, the first bearings 5111 being ball bearings. The pivot 54 may pass through the stop ring 55, the inner ring of the ball bearing, the collar 56, the weight wheel 53 and the weight assembly 52 from bottom to top (up and down direction shown in fig. 7), and the weight wheel 53 and the weight assembly 52 are connected to the main substrate 511 through the first bearing 5111 and the pivot 54. The weight assembly 52 and the weight wheel 53 can rotate around the central axis of the pivot shaft 54.

As shown in fig. 7, the main substrate 511 may be provided with a boss 5113 protruding toward the weight wheel 53, and the mounting hole 5112 may penetrate the boss 5113, thereby increasing the thickness of the main substrate 511 and securing the mounting space of the first bearing 5111. For example, as shown in fig. 7, the boss 5113 on the main substrate 511 is formed as a boss 5113 that protrudes upward (in the up-down direction shown in fig. 7), and the mounting hole 5112 penetrates the boss 5113 in the thickness direction (in the up-down direction shown in fig. 7) of the main substrate 511, whereby not only the thickness at the center of the main substrate 511 can be increased, the amount of material used can be reduced, but also the structure of the smart watch 1 can be made more compact and reasonable.

As shown in fig. 3, the weight wheel 53 may include a weight body 531 and weight gear teeth 532 formed on the outer circumference of the weight body 531, the weight body 531 is formed with a central hole 533, the pivot shaft 54 may pass through the central hole 533 of the weight body 531, and the weight gear teeth 532 are engaged with the first pinion 4111. The surface of the weight main body 531 adjacent to the main substrate 511 may protrude away from the main substrate 511, thereby making it possible to make reasonable use of space and to make the structure of the power input assembly 50 more reasonable. Further, the surface of the weight main body 531 adjacent to the weight assembly 52 may also protrude away from the main substrate 511, thereby reducing the weight of the weight sheave 53 and saving materials. The shape of the surface of the weight main body 531 adjacent to the weight element 52 is not limited to this, and the surface of the weight main body 531 adjacent to the weight element 52 may be formed as a plane, thereby simplifying the processing process.

For example, as shown in fig. 3, the weight wheel 53 includes a weight main body 531 and weight wheel teeth 532, the weight main body 531 is formed with a central hole 533, the pivot shaft 54 passes through the central hole 533 to connect with the weight wheel 53, and the weight main body 531 is formed with a plurality of fan-shaped through holes 534 uniformly distributed along the circumference of the central hole 533, so that the weight of the weight main body 531 can be reduced, and the smart watch 1 is lighter. The surface of the weight main body 531 adjacent to the main substrate 511 protrudes away from the main substrate 511, and the surface of the weight main body 531 adjacent to the weight assembly 52 also protrudes away from the main substrate 511, so that the weight of the weight bull wheel 53 can be reduced, thereby saving material and reducing production cost, and the structure of the power input assembly 50 can be more compact and reasonable. The shape of the through hole 534 is not limited to this, and the through hole 534 may be formed in other shapes such as a circle or an ellipse, thereby facilitating the processing of the weight main body 531.

As shown in fig. 7, the main substrate 511 may be provided with a mounting platform 5114 protruding toward the weight wheel 53, the mounting platform 5114 may be spaced apart from the mounting hole 5112, and the upper clamp plate 512 may be fixed to the mounting platform 5114 and define a mounting cavity 514 for accommodating the transmission 40 together with the main substrate 511. Therefore, the transmission device 40 can be installed in the installation cavity 514 defined by the upper clamping plate 512 and the main substrate 511, and the structure of the intelligent watch 1 is more compact. For example, as shown in fig. 7, an installation platform 5114 protruding upward is provided on the main substrate 511, the installation platform 5114 is provided with two screw holes 5116 and two positioning pins 5115, a through hole 5121 is provided on the upper clamp plate 512 at a position corresponding to the screw hole 5116 of the installation platform 5114, a screw fastener 515 is installed in the through hole 5121, and a positioning pin 5115 hole is formed on the upper clamp plate 512 at a position corresponding to the positioning pin 5115, so that in the process of installing the upper clamp plate 512 and the main substrate 511, the upper clamp plate 512 and the main substrate 511 are firstly connected in a positioning manner through the positioning pin 5115, and then the upper clamp plate 512 and the main substrate 511 are tightly connected through the screw fastener 515, so that an installation cavity 514 is formed between the upper clamp plate 512 and the main.

According to some embodiments of the present invention, each stage of gear assembly 41 can be mounted in the mounting cavity 514 through the second bearing 513, thereby making the structure of the energy collecting module 400 more reasonable and compact. Further, the second bearing 513 may be a jewel bearing. The jewel bearing has the advantages of small friction coefficient, high hardness and small linear expansion coefficient, so that the wear resistance of the jewel bearing can be improved, and the service life of the structure can be prolonged.

For example, as shown in fig. 7, bearing mounting holes 5112 are provided in one-to-one correspondence to the positions of the main substrate 511 and the upper plate 512, and jewel bearings may be fitted in the bearing mounting holes 5112. First gear drive subassembly 411 can also be installed in installation cavity 514 through a pair of precious stone bearing that main substrate 511 and punch holder 512 correspond, and second gear drive subassembly 412 can also be installed in installation cavity 514 through a pair of precious stone bearing, not only can the rational utilization space from this, makes the compact structure of energy collection module 400, can also reduce gear drive subassembly 41's frictional resistance, improves gear drive subassembly 41's transmission efficiency, increase of service life.

According to some embodiments of the present invention, the pivot shaft 54 may be formed as a sleeve 541 having an internal thread, and the pivot shaft 54 may be provided with a threaded fastener 542 engaged with the internal thread, thereby facilitating the mounting and dismounting of the pivot shaft 54. The weight wheel 53 and the weight assembly 52 are sleeved on the sleeve 541 and fixed on the main substrate 511 by a threaded fastener 542. Therefore, the maintenance and replacement of the weight wheel 53 and the weight assembly 52 can be facilitated. For example, as shown in fig. 5, the pivot shaft 54 includes a sleeve 541 having an internal thread and a threaded fastener 542 matching with the internal thread, during the installation of the power input assembly 50, one end of the sleeve 541 passes through the retainer ring 55, the ball bearing inner ring, the collar 56, the weight sheave 53 and the weight assembly 52 from bottom to top in sequence, and then the retainer ring 55, the ball bearing, the collar 56, the weight sheave 53 and the weight assembly 52 are integrally fixed on the main substrate 511 by the threaded fastener 542, thereby facilitating the maintenance and replacement of the above components.

According to an embodiment of the present invention, the weight assembly 52 may include a swinging plate 521 and a weight 522, the swinging plate 521 may be mounted on the pivot 54, and the weight 522 may be disposed at an end of the swinging plate 521 away from the pivot 54. The weight 522 can rotate around the central axis of the pivot shaft 54 under the action of external force. Further, the swinging plate 521 and the weight 522 can be riveted, so that the assembly process can be simplified and the cost can be reduced.

A boss 5113 is arranged at the center of the main substrate 511, a mounting hole 5112 penetrating through the boss 5113 is formed on the boss 5113, and a ball bearing is mounted in the mounting hole 5112.

The power input assembly 50 includes a weight assembly 52 and a weight bull wheel 53. The weight assembly 52 includes a weight 522 and a swing plate 521, wherein the weight 522 is an eccentric mass made of high-density alloy W-Ni-Fe alloy and is riveted with the swing plate 521 into a whole. The sleeve 541 of the pivot 54 passes through the ball bearing inner race to connect the retainer 55, the ball bearing, the collar 56, the weight wheel 53 and the weight assembly 52 together and is fastened by the threaded fastener 542. Under the action of an external force perpendicular to the axial direction of the ball bearing, the power input assembly 50 can swing around the axial direction of the ball bearing due to the eccentric action of the weight assembly 52.

The transmission device 40 includes a first gear assembly 411 and a second gear assembly 412, the first gear assembly 411 includes a first small gear 4111 and a first large gear 4112, the first small gear 4111 and the first large gear 4112 are riveted into a whole and mounted in a pair of jewel bearings corresponding to the main substrate 511 and the upper plate 512. The second gear assembly 412 includes a second pinion gear 4121 and a second bull gear 4122, and the second pinion gear 4121 and the second bull gear 4122 are riveted to be integrated and mounted in a pair of jewel bearings corresponding to the main base plate 511 and the upper plate 512. Whereby the first gear assembly 411 and the second gear assembly 412 are free to rotate about the axis of the respective jewel bearings. The first small gear 4111 is engaged with the weight wheel 53, the first large gear 4112 is engaged with the second small gear 4121, and the second large gear 4122 is engaged with the input gear 61.

The power generation assembly 60 includes an input gear 61, a support body 62, a permanent magnet 63, a stator core 64, a winding core 65, a winding base 66, and a winding 67. The support 62 is integrally riveted to the input gear 61 and the permanent magnet 63, and is mounted to a pair of jewel bearings of the upper plate 512 corresponding to the main substrate 511. The winding seat 66 is sleeved on the winding iron core 65, and the winding 67 is wound on the winding seat 66. The stator core 64 is formed with a circular hole 641, and the permanent magnet 63 is installed in the circular hole 641 with a certain gap from the inner surface of the circular hole 641. The energy storage assembly includes a supercapacitor for storing electrical energy.

When the weight assembly 52 is subjected to an external force perpendicular to the axial direction of the ball bearing, the power input assembly 50 can swing or rotate around the axial direction of the ball bearing under the action of the eccentricity. That is, the weight assembly 52 drives the weight wheel 53 to rotate together. Since the weight bull wheel 53 is engaged with the first pinion gear 4111, the rotation of the power input assembly 50 can drive the first pinion gear 4111 and the first bull gear 4112 of the first gear assembly 411 to rotate together. And the reference circle diameter of the weight bull wheel 53 is larger than the reference circle diameter of the first small gear 4111, so the rotation speed of the first small gear 4111 and the first large gear 4112 is larger than the rotation speed of the weight bull wheel 53, and the linear velocity of the first large gear 4112 is larger than the linear velocity of the first small gear 4111 and the weight bull wheel 53. The first gearwheel 4112 is engaged with the second gearwheel 4121, so that the first gearwheel 4112 can drive the second pinion 4121 and the second gearwheel 4122 to rotate, and since the pitch circle diameter of the second pinion 4121 is smaller than that of the first gearwheel 4112, the rotational speed of the second pinion 4121 and the second gearwheel 4122 is greater than that of the first gearwheel 4112, and the linear speed of the second gearwheel 4122 is greater than that of the second pinion 4121 and the first gearwheel 4112.

The second bull gear 4122 is engaged with the input gear 61 of the power generation assembly 60 so that the second bull gear 4122 can drive the input gear 61 and the permanent magnet 63 to rotate. Since the pitch circle diameter of the second large gear 4122 is larger than the pitch circle diameter of the input gear 61, the rotational speed of the input gear 61 and the permanent magnet 63 is larger than the rotational speed of the second large gear 4122. That is, the coaxial gear acts to increase the linear velocity and the non-coaxial gear transmission acts to increase the rotational speed. The transmission path of the kinetic energy is as follows: is transmitted from the power input assembly 50 to the first pinion gear 4111 and the first bull gear 4112, thereby increasing the rotational speed of the first pinion gear 4111 and the first bull gear 4112 and increasing the linear speed of the first bull gear 4112. Then from the first large gear 4112 to the second small gear 4121 and the second large gear 4122, thereby increasing the rotation speed of the second small gear 4121 and the second large gear 4122, increasing the linear speed of the second large gear 4122, and finally from the second large gear 4122 to the input gear 61 and the permanent magnet 63, thereby increasing the rotation speed of the input gear 61 and the permanent magnet 63.

When the permanent magnet 63 rotates, an alternating magnetic flux may be generated in the winding core 65, that is, an alternating magnetic flux may be generated inside the winding 67, so that an induced electromotive force may be generated in the winding 67 according to the principle of electromagnetic induction. The windings 67 are electrically connected to the energy storage assembly whereby the generated electrical energy can be transferred into a super capacitor in the energy storage assembly for use by the smart watch 1.
