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 can be used to mount various components of the power input assembly 50. The power input assembly 50 includes a weight assembly 52 and a heavy hammer 53. The weight assembly 52 is pivotally mounted on the base plate portion 51 by the pivot shaft 54 and the center of gravity of the weight assembly 52 is offset from the central axis of the pivot shaft 54, whereby the weight assembly 52 can be pivoted when the smart watch 1 is shaken The central axis of the rotary shaft 54 is swung or rotated. The heavy hammer wheel 53 can be fixed to the pivot shaft 54, whereby the weight large wheel 53 and the pivot shaft 54 can be configured to move together as a whole. It should be noted that the heavy hammer wheel 53 can be detachably connected to the pivot shaft 54 by fasteners to facilitate the repair and replacement of the heavy hammer wheel 53; of course, the heavy hammer wheel 53 can also be coupled with the pivot shaft 54. The integral molding can reduce the number of components of the energy collecting module 400 and simplify the assembly process. The heavy hammer wheel 53 can be coupled to the transmission 40 such that the kinetic energy collected by the power input assembly 50 can be transmitted to the transmission 40.

The power generating unit 60 can be provided on the substrate 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 the kinetic energy transmitted by the power input assembly 50 to the transmission 40 into electrical energy. Thereby, energy collection and conversion can be achieved to achieve the purpose of self-generation. The energy storage component can be electrically coupled to the power generation component 60, thereby facilitating storage of electrical energy generated by the power generation component 60 into the energy storage component.

As shown in FIGS. 3 and 4, the weight assembly 52 of the power input assembly 50 is rotated or oscillated by an external force and transmitted to the power generating assembly 60 through the transmission 40.

According to some embodiments of the invention, the transmission 40 may include a multi-stage gearing assembly 41, multi-stage teeth The wheel drive assemblies are sequentially connected and there is at least one pair of adjacent two-stage gear drive assemblies having a gear ratio of less than one. It should be noted that, by the formula of the transmission ratio (transmission ratio = driving wheel rotation speed divided by the value of the driven wheel rotation speed = the reciprocal of their index circle diameter), it is known that at least one pair of adjacent two-stage gear transmission components are The transmission ratio is less than one. When the rotational speed of the active gear transmission assembly is constant, the rotational speed of the driven gear transmission assembly is greater than the rotational speed of the active gear transmission assembly. Thereby, the rotational speed of the multi-stage gear transmission assembly 41 can be effectively increased by providing a multi-stage gear transmission assembly, so that the electric energy generated by the power generation assembly 60 can be improved, thereby increasing the amount of power generation. In addition, the gear transmission has the advantages of compact structure, long service life and high transmission ratio, thereby not only making the smart watch 1 compact in structure, improving the service life of the smart watch 1, but also utilizing a higher transmission ratio to improve transmission to power generation. The kinetic energy of the assembly 60 increases the amount of power generated.

For example, as shown in FIG. 6, the first gear transmission assembly 411 is a drive gear transmission assembly, the second gear transmission assembly 412 is a driven gear transmission assembly, and the first gear transmission assembly 411 transmits kinetic energy to the second gear transmission assembly 412. The transmission ratio of the first gear transmission assembly 411 and the second gear transmission assembly 412 is less than one, that is, the rotation speed of the second gear transmission assembly 412 is greater than the rotation speed of the first gear transmission assembly 411.

Wherein, the first gear transmission assembly 411 is meshed with the second gear transmission assembly 412. It should be noted that the first gear transmission assembly 411 can directly mesh with the second gear transmission assembly 412, as shown in FIG. Of course, the multi-stage gear transmission assembly 41 may further include a third gear transmission assembly, wherein the first gear transmission assembly 411 transmits kinetic energy to the second gear transmission assembly 412 through the third gear transmission assembly, at this time, the first gear transmission assembly 411 is in indirect engagement with the second gearing assembly 412. Additionally, the multi-stage gearing assembly 41 may not be limited to include two and three gearing assemblies, but may also be a multi-stage gearing assembly 41 that includes four or more gearing assemblies.

As shown in FIG. 6, the first gear transmission assembly 411 may include a first pinion gear 4111 and a first large gear 4112 fixed coaxially with the first pinion gear 4111, whereby the first pinion gear 4111 and the first large gear 4112 are The coaxial speed can be maintained during the rotation. It will be appreciated that the pitch circle diameter of the first pinion gear 4111 may be smaller than the pitch circle diameter of the first bull gear 4112, thereby facilitating kinetic energy transfer between the multi-stage gear drive assemblies. In addition, it should be noted that the first pinion gear 4111 and the first large gear wheel 4112 may be fixed to be coaxially rotated by being riveted and fixed, or may be connected to each other to maintain coaxial rotation by other connection means. The first pinion gear 4111 can be meshed with the heavy hammer wheel 53, thereby facilitating transmission of the kinetic energy of the heavy hammer wheel 53 to the first gear transmission assembly 411. Here, the pitch circle diameter of the first pinion gear 4111 may be smaller than or equal to the pitch circle diameter of the weight large wheel 53, whereby the rotation speed of the first pinion gear 4111 can be increased.

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 multi-stage gear drive assemblies. The second pinion gear 4121 meshes with the first large gear 4112 and the pitch circle diameter of the second pinion gear 4121 is smaller than the pitch circle diameter of the first large gear 4112, thereby facilitating the kinetic energy transfer between the multi-stage gear transmission components. . It can be understood that the pitch circle diameter of the second pinion gear 4121 can be smaller than the pitch circle diameter of the first large gear 4112, thereby not only facilitating the kinetic energy transfer between the multi-stage gear transmission components, but also effectively improving The rotational speed of the second pinion 4121.

It should be noted that the second pinion gear 4121 and the first large gear 4112 may be directly engaged or indirectly engaged. For example, as shown in FIG. 6, the second pinion gear 4121 and the first large gear 4112 can be directly meshed for kinetic energy transfer. Of course, the multi-stage gearing assembly 41 can also include a third gearing assembly, in which case the second pinion 4121 and the first bull gear 4112 are indirectly meshed by the third gearing assembly. Further, the second large gear 4122 is adapted to mesh with the input gear 61 of the power generating assembly 60, whereby the kinetic energy of the multi-stage gearing assembly 41 can be transmitted to the power generating assembly 60, causing the input gear 61 of the power generating assembly 60 to rotate for power generation. Here, the index 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 number of revolutions of the input gear 61 can be further increased, so that the amount of power generation of the power generating unit 60 can be increased.

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 be swung or rotated about the axis of the ball bearing under the action of the eccentricity. That is to say, the weight assembly 52 will cause the heavy hammer 53 to rotate together. Since the weight large wheel 53 meshes with the first pinion gear 4111, the rotation of the power input assembly 50 can drive the first pinion gear 4111 of the first gear transmission assembly 411 to rotate together with the first large gear 4112.
