[0004] The main object of the present invention is to provide a light-driven motor structure that can convert light energy into electrical energy for operating the motor through a photovoltaic cell, has simple components, and is suitable for being installed in a sealed space and continuously operating.

Means for Solving the Problems

[0005] To achieve the above object, the light-driven motor structure provided by the present invention converts light energy into electrical energy by a photovoltaic cell included in the optoelectronic part, and supplies the electrical energy to a plurality of coil units included in the stator part, thereby generating corresponding magnetic forces respectively. The magnetic forces generated by a plurality of magnetic units included in the adjacent rotor part interact with each other, resulting in the effect of rotationally driving other elements.

[0006] In order to fix the stator part, the rotor part and the optoelectronic part so that they can be mounted in a sealed space, the optical drive motor structure may further include a casing part, and the casing part provides an accommodation space for accommodating the components of the stator part, the rotor part and at least a part of the optoelectronic part, so that the relative position between the coil unit of the stator part and the magnetic unit of the rotor part is positioned, and the interaction between these magnetic forces can proceed smoothly.

[0007] In order to enable the photovoltaic cell to smoothly receive external light energy, the photovoltaic cell is provided outside the casing part, with the light receiving surface facing the opposite side of the casing part, preventing light from being blocked by the casing part and unable to be received by the photovoltaic cell.

Modes for Carrying Out the Invention

[0009] Hereinafter, the present invention will be described more specifically with reference to the drawings by way of specific embodiments.

[0010] First, please refer to FIGS. 1 to 3. The optical drive motor structure 10 provided in the preferred embodiment of the present invention mainly includes a casing part 20, a stator part 30, a rotor part 40, an optoelectronic part 50, and a non-magnetic spacer 60.

[0011] The casing part 20 includes a cylindrical base 21, and a disc-shaped lid 22 is detachably covered on the cylindrical opening 211 of the base 21 to seal the cylindrical opening 211 of the base 21. Thus, a substantially cylindrical accommodation space 23 for accommodating the stator part 30, the rotor part 40, the spacer 60, and at least a part of the photoelectric part 50 is defined by the base 21 and the lid 22.

[0012] The stator part 30 and the rotor part 40 are configured as an axial-flux motor. Since the flux formation technology is a conventional technology, detailed description is omitted here. Only the part related to the present invention will be described here. The stator part 30 includes a plurality of coil units 31 radially arranged in the accommodation space 23 around an axis 70 parallel or coaxial with the column axis of the accommodation space 23. The rotor part 40 includes a plurality of magnetic units 41 radially arranged in the accommodation space 23 around the axis 70. The rotor part 40 and the stator part 30 are spaced apart from each other in the axial direction 70, and the spacer 60 is positioned between the rotor part 40 and the stator part 30 to form an air gap.

[0013] Furthermore, the stator part 30 further includes two substantially disc-shaped first mounting pieces 32. The diameter of each first mounting piece 32 is approximately equal to or slightly smaller than the column diameter of the accommodation space 23. Each first mounting piece 32 can be provided and positioned coaxially with the column axis of the accommodation space 23 in the accommodation space 23. Each first mounting piece 32 is adhered to both axial ends of the plurality of coil units 31 respectively, thereby sandwiching the plurality of coil units 31 and fixing their relative angular positions, and can be accommodated in the accommodation space 23 together with each first mounting piece 32.

[0014] Each of the plurality of magnetic units 41 is a permanent magnet, and is fixed on the sealed cylindrical bottom wall 212 in the base 21, and is separated from the plurality of coil units 31 in the direction of the axis 70 by the spacer 60.

[0015] The photoelectric part 50 includes a plurality of photovoltaic cells 51 such as solar cells for converting light energy into electrical energy, and a second mounting piece 52 that is electrically connected (connection lines not shown) to the plurality of photovoltaic cells 51 and the plurality of coil units 31 respectively, so as to supply the electrical energy converted by the plurality of photovoltaic cells 51 to the plurality of coil units 31 to form corresponding magnetic fields. The second mounting piece 52 is accommodated in the accommodation space 23, the plurality of photovoltaic cells 51 are outside the casing part 20 and fixed on the lid body 22 to receive external light energy.

[0016] Thereby, the light-driven motor structure 10 converts the light energy received through the plurality of photovoltaic cells 51 into electrical energy, transmits the electrical energy to the plurality of coil units 31 through the connected circuit, generates corresponding magnetic forces, and interacts with the magnetic forces generated by the plurality of magnetic units 41 to achieve a rotating effect.

[0017] Also, in order to facilitate the electrical connection between the plurality of photovoltaic cells 51 and the second mounting piece 52, the casing part 20 may further include a through hole 24 penetrating through the lid body 22 as a passage for an electric wire (not shown) constituting the electrical connection to pass through the casing part 20.

[0018] In addition, in order to increase the conversion capacity of the plurality of photovoltaic cells 51, the number of photovoltaic cells 51 is increased, a photovoltaic cell 51a is additionally provided on the second mounting piece 52 and accommodated in the accommodation space. The casing part 20 further includes a plurality of light-transmitting holes 25. In order to increase the conversion capacity, light irradiates the light-receiving surface of the photovoltaic cell 51a in the accommodation space 23 through the plurality of light-transmitting holes 25, so that the photovoltaic cell 51 outside the lid body can perform photoelectric conversion together.

[0019] Furthermore, the casing part 20 is penetrated through the cylindrical bottom wall 212 of the base 21 and further includes a plurality of fitting holes 26 for fitting the plurality of magnetic units 41.
