Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0051] Please refer to Figures 1 to 8. This utility model proposes a power-generating device 30. The power-generating device 30 of this utility model includes a housing 310 and a power module 320.

[0052] Please refer to Figures 1 and 2. The outer casing 310 of this utility model includes a first casing portion 311 and a second casing portion 312. The first casing portion 311 is used to connect to the ceiling, and the second casing portion 312 is used to install a millimeter-wave radar. The millimeter-wave radar detects the activities of the elderly by transmitting and receiving millimeter waves, and can issue an alarm when it determines that the elderly are facing an emergency based on the detection results. The outer casing 310 of this utility model installs the aforementioned millimeter-wave radar through the second casing portion 312, and is connected to the ceiling through the first casing portion 311. Therefore, the millimeter-wave radar can also be fixed to the ceiling, thereby covering a larger area of ​​the house and achieving a wide field of view monitoring. It should be noted that those skilled in the art can adapt the structure of the outer casing 310 according to existing millimeter-wave radar designs. Any power supply device 30 adjusted based on the above description is within the protection scope of this utility model.

[0053] Please refer to Figures 1 and 3. The power module 320 of this utility model includes a power extraction unit 321, a first power supply unit 322, and a second power supply unit 323. The power extraction unit 321 is used to electrically connect to the lighting circuit 10 on the ceiling. The first power supply unit 322 and the second power supply unit 323 are both electrically connected to the power extraction unit 321. The first power supply unit 322 is used to electrically connect to the lighting lamp 20, and the second power supply unit 323 is used to electrically connect to the millimeter-wave radar. Through the electrical connection between the power extraction unit 321, the first power supply unit 322, and the second power supply unit 323, electricity from the lighting circuit 10 can be introduced into the first power supply unit 322 and the second power supply unit 323 respectively. When the first power supply unit 322 is electrically connected to the lighting lamp 20 and the second power supply unit 323 is electrically connected to the millimeter-wave radar, the lighting circuit 10 can simultaneously supply power to both the lighting lamp 20 and the millimeter-wave radar, thereby enabling both the lighting lamp 20 and the millimeter-wave radar to operate simultaneously. The above solution meets the power supply requirements of the lighting lamp 20 and the millimeter-wave radar while avoiding the need for additional power supply lines and simplifying the installation of the millimeter-wave radar.

[0054] It should be noted that this utility model does not limit the specific manner in which the first housing 311 is connected to the ceiling. In some embodiments, the first housing 311 is adhered to the ceiling. In other embodiments, the first housing 311 is installed on the ceiling by fasteners. As a preferred embodiment, referring to Figures 1 and 2, the first housing 311 further includes expansion bolts 3111, and the first housing 311 is fixed to the ceiling by the expansion bolts 3111. The above solutions enable the power supply device 30 to be more securely fixed to the ceiling, reducing the risk of the power supply device 30 accidentally falling.

[0055] On the other hand, the housing 310 of this invention is used to mechanically mount the millimeter-wave radar to the ceiling, while the power module 320 is responsible for distributing the electrical energy from the existing lighting circuit 10 to the lighting lamp 20 and the millimeter-wave radar. Therefore, this invention does not impose any restrictions on the positional relationship between the housing 310 and the power module 320. In some embodiments, the power module 320 is disposed on the outside of the housing 310.

[0056] As a preferred embodiment, referring to Figures 1, 2, and 4, in some embodiments, the housing 310 has a receiving cavity 313 inside, in which at least a portion of the power module 320 is received. The first housing portion 311 and the second housing portion 312 are detachably connected to form the receiving cavity 313 together, or the receiving cavity 313 can be opened. At least a portion of the power module 320 can be installed into the receiving cavity 313 when the first housing portion 311 and the second housing portion 312 are open, and is protected by the housing 310 after the first housing portion 311 and the second housing portion 312 are connected, reducing the possibility of contact with external moisture, dust, etc., and further extending its service life.

[0057] Without departing from the inventive concept of this utility model, those skilled in the art can install different parts of the power module 320 into the receiving cavity 313. Please refer to Figures 1, 3, 4, and 5, where Figures 4 and 5 show a cross-section of the power extraction device 30 in Figure 1 perpendicular to the vertical direction (i.e., the up-down direction in Figure 1). In some embodiments, the first power supply unit 322 and the second power supply unit 323 are disposed in the mounting cavity.

[0058] Further, referring to Figures 2 and 5, in some embodiments, the power-taking unit 321 includes a power-taking interface 3211, the first power supply unit 322 includes a first power supply interface 3221, and the side of the housing 310 is provided with a power-taking port 315 and a first power supply port 316 communicating with the receiving cavity 313. The power-taking port 315 is used to expose the power-taking interface 3211 so that the power-taking port 315 can be electrically connected to the lighting circuit 10, and the first power supply port 316 is used to expose the first power supply interface 3221 so that the first power supply interface 3221 can be electrically connected to the lighting lamp 20. With the above solution, the terminals of the lighting circuit 10 and the lighting lamp 20 can both extend into the housing 310. The housing 310 can protect the terminals of the lighting circuit 10 and the lighting lamp 20, thereby enhancing the stability of the electrical connection between the lighting circuit 10 and the power module 320 and the lighting lamp 20 and the power module 320. Furthermore, the user can connect one end of the lighting circuit 10 to the power interface 3211 to make the lighting circuit 10 and the power interface 321 electrically connected, and connect one end of the lighting lamp 20 to the first power interface 3221 to make it electrically connected to the first power supply 322.

[0059] Further, referring to Figure 3, in some embodiments, the power-gathering device 30 further includes a first wireless switch 330; the power module 320 further includes a first wireless control module 324, and the second power supply unit 323 is electrically connected to the power-gathering unit 321 through the first wireless control module 324; the first wireless control module 324 is configured to connect the power-gathering unit 321 and the second power supply unit 323 when the first wireless switch 330 is turned on, and to disconnect the electrical connection between the power-gathering unit 321 and the second power supply unit 323 when the first wireless switch 330 is turned off.

[0060] In existing technologies, millimeter-wave radar obtains power through additional circuitry, which includes a switch allowing users to individually switch the radar's operating state. The above embodiment, however, avoids this additional wiring by incorporating a first wireless switch 330 and a first wireless control module 324. This allows users to switch the millimeter-wave radar's operating state while keeping the lighting fixture 20 running. Furthermore, the location of the first wireless switch 330 can be adjusted according to the specific home environment, facilitating user control of the millimeter-wave radar.

[0061] It should be noted that the first wireless switch 330 in this utility model is not limited to existing wireless switches, but can also be a mobile phone or remote control with an application installed that can switch the state of the first wireless control module 324.

[0062] Without departing from the inventive concept of this utility model, those skilled in the art can make other improvements to the power module 320.

[0063] Referring to Figure 3, in some embodiments, the power-gathering device 30 further includes a second wireless switch (not shown in the figure); the power module 320 further includes a second wireless control module 325, and the power-gathering unit 321 is electrically connected to the lighting circuit 10 through the second wireless control module 325; the second wireless switch is signal-connected to the second wireless control module 325, and the second wireless control module 325 is configured to electrically connect the power-gathering unit 321 and the second power supply unit 323 when the second wireless switch is turned on, and to disconnect the electrical connection between the power-gathering unit 321 and the second power supply unit 323 when the second wireless switch is turned off. With this solution, the user can control the on / off connection between the power-gathering unit 321 and the lighting circuit 10 by switching the state of the second wireless switch, thereby controlling the overall power supply of the power-gathering device 30. Furthermore, the position of the second wireless switch can be changed according to the actual home environment, facilitating user control of the millimeter-wave radar.

[0064] It should be noted that the second wireless switch in this invention is not limited to existing wireless switches, but can also be a mobile phone or remote control with an application installed that can switch the state of the second wireless control module 325. As described above, embodiments including the first wireless switch 330 are also available. In some embodiments, the first wireless switch 330 and the second wireless switch can be integrated into a single control device, such as a mobile phone or remote control with an application installed that can switch the state of the first wireless control module 324 and the second wireless control module 325.

[0065] Referring to Figure 3, in some embodiments, the power supply device 30 further includes a third switch 327. The third switch 327 is installed on the power supply device 30 and is electrically connected to the lighting circuit 10 via a wire. When the third switch 327 is open, it electrically connects the power supply unit 321 and the second power supply unit 323; when the third switch 327 is closed, it disconnects the electrical connection between the power supply unit 321 and the second power supply unit 323. With this solution, when the user needs to approach the power supply device 30 for maintenance, they can directly control the connection between the power supply unit 321 and the lighting circuit 10 by switching the state of the third switch 327, thereby controlling the overall power supply of the power supply device 30.

[0066] In some embodiments, the power module 320 further includes a high-voltage to low-voltage conversion module 326, and the second power supply unit 323 is electrically connected to the power extraction unit 321 through the high-voltage to low-voltage conversion module 326. Through this scheme, the power extraction device 30 has a high-voltage to low-voltage conversion function. The current output from the power extraction unit 321 to the second power supply unit 323 can be adjusted by the high-voltage to low-voltage conversion module 326 to become low-voltage, thereby enabling the power extraction device 30 to output high-voltage power to the lighting lamp 20 while also outputting low-voltage power to the millimeter-wave radar.

[0067] This invention also proposes a millimeter-wave monitoring system, including a millimeter-wave radar 40 and a power supply device 30 as described in any of the above embodiments. The millimeter-wave radar 40 is connected to the second housing 312 and electrically connected to the second power supply unit 323. Through this design, the millimeter-wave radar 40 can be fixed to the ceiling and receive power from the lighting circuit 10, while the emitted millimeter waves can cover a larger area of ​​the house, achieving wide-field-of-view monitoring. This system meets the power supply requirements of the lighting lamp 20 and the millimeter-wave radar 40 while avoiding the addition of power supply lines, making the overall installation process simpler.

[0068] Without departing from the inventive concept of this utility model, those skilled in the art can adjust the connection between the millimeter-wave radar 40 and the power supply device 30. In some embodiments, the second housing 312 is bonded to the millimeter-wave radar 40. In other embodiments, the second housing 312 is integrally connected to the millimeter-wave radar 40.

[0069] As a preferred embodiment, referring to Figures 8, 9, and 10, in some embodiments, the second housing 312 and the millimeter-wave radar 40 are detachably connected. The second power supply unit 323 further includes an output connector 3231, and the millimeter-wave radar 40 further includes a receiving connector 430. The output connector 3231 and the receiving connector 430 are detachably connected to allow the second power supply unit 323 to be electrically connected to or disconnected from the millimeter-wave radar 40. Through the above solutions, those skilled in the art can completely separate the millimeter-wave radar 40 from the power supply device 30 by disconnecting the connection between the output connector 3231 and the receiving connector 430, and by disconnecting the second housing 312 and the millimeter-wave radar 40, facilitating individual maintenance of the millimeter-wave radar 40.

[0070] Without departing from the inventive concept of this utility model, those skilled in the art can adjust the connection configuration between the millimeter-wave radar 40 and the power-generating device 30. In some embodiments, the output connector 3231 is disposed on the second housing 312, and the output connector 3231 and the receiving connector 430 are detachably connected, so that the second power supply unit 323 is electrically connected to the millimeter-wave radar 40 and the millimeter-wave radar 40 is fixed to the power-generating device 30, or the electrical connection between the second power supply unit 323 and the millimeter-wave radar 40 is disconnected and the millimeter-wave radar 40 is separated from the power-generating device 30. In some embodiments, the millimeter-wave radar 40 and the second housing 312 are also connected by Velcro.

[0071] As a preferred embodiment, referring to Figures 6, 7, 9, and 10, in some embodiments, one of the second housing portion 312 and the millimeter-wave radar 40 has a snap-fit ​​groove 51, and the other includes a snap-fit ​​portion 52. The snap-fit ​​groove 51 has a first groove portion 511 and a second groove portion 512 that are connected. The width of the first groove portion 511 is H1, the width of the second groove portion 512 is H2, and the width of the snap-fit ​​portion 52 is H3, where H1 > H3 > H2. The snap-fit ​​portion 52 can be inserted upward from the first groove portion 511 into the snap-fit ​​groove 51 and move to the second groove portion 512 to snap into the snap-fit ​​groove 51 vertically. With the above solution, after the snap-fit ​​portion 52 and the snap-fit ​​groove 51 are snapped together, the housing 310 of the power-taking device 30 can restrict the vertical movement of the millimeter-wave radar 40, thereby realizing the connection between the millimeter-wave radar 40 and the second housing portion 312.

[0072] Based on the above solution, those skilled in the art can further provide multiple snap-fit ​​slots 51 and snap-fit ​​portions 52 to strengthen the connection between the power supply device 30 and the millimeter-wave monitoring system through the snap-fit ​​between the multiple snap-fit ​​slots 51 and snap-fit ​​portions 52. For example, referring to Figures 9 and 10, in some embodiments, the second housing 312 includes two snap-fit ​​portions 52, and the millimeter-wave radar 40 has two snap-fit ​​slots 51, with the two snap-fit ​​portions 52 capable of snapping into different snap-fit ​​slots 51 respectively.

[0073] In this embodiment of the invention, the latching portion 52 can first be inserted upwards from the first slot 511 into the latching groove 51, and then move to the second slot 512. It should be noted that this invention does not restrict the manner in which the latching portion 52 inserted into the latching groove 51 moves to the second slot 512. In some embodiments, the latching portion 52 inserted into the latching groove 51 translates to the second slot 512. In other embodiments, referring to Figures 9 and 10, the latching portion 52 inserted into the latching groove 51 rotates about a vertical axis to the second slot 512.

[0074] After determining the manner in which the engaging portion 52 moves to the second slot 512, those skilled in the art can also adaptively adjust the shape of the engaging slot 51. For example, referring to Figures 9 and 10, in some embodiments, the second housing portion 312 includes two engaging portions 52, and the millimeter-wave radar 40 has two engaging slots 51. The first slot 511 and the second slot 512 of each engaging slot 51 are arranged around a vertical axis, and the two engaging portions 52 can engage with different engaging slots 51 respectively.

[0075] Without departing from the inventive concept of this utility model, those skilled in the art can also adjust the structure of the millimeter-wave radar 40. Referring to Figures 8, 9, and 10, in some embodiments, the millimeter-wave radar 40 has a second receiving groove 420, and a receiving connector 430 is disposed on the inner wall of the second receiving groove 420. When the receiving connector 430 and the output connector 3231 are connected, the output connector 3231 is accommodated in the second receiving groove 420. Through this solution, when the output connector 3231 and the receiving connector 430 are connected, the output connector 3231 accommodated in the second receiving groove 420 can be protected by the inner wall of the second receiving groove 420, thereby enabling a more stable connection to the receiving connector 430 and improving the operational stability of the millimeter-wave monitoring system. On the other hand, the output connector 3231 extending into the second receiving groove 420 can further reduce the distance between the millimeter-wave radar 40 and the power-taking device 30, making the millimeter-wave radar 40 and the power-taking device 30 fit more closely, which is beneficial to enhance the connection strength between the millimeter-wave radar 40 and the power-taking device 30, and the power-taking device 30 can also further protect the connection between the receiving connector 430 and the output connector 3231.

[0076] In other embodiments, the housing 310 has a first receiving groove, and the output connector 3231 is disposed on the inner wall of the first receiving groove (not shown in the figure). When the receiving connector 430 and the output connector 3231 are connected, the receiving connector 430 is accommodated in the first receiving groove. Through this scheme, when the output connector 3231 and the receiving connector 430 are connected, the receiving connector 430 accommodated in the first receiving groove is protected by the inner wall of the first receiving groove, thereby enabling a more stable connection to the output connector 3231 and improving the operational stability of the millimeter-wave monitoring system. On the other hand, the receiving connector 430 extending into the first receiving groove can further reduce the distance between the millimeter-wave radar 40 and the power-taking device 30, making them fit more closely together. This helps to enhance the connection strength between the millimeter-wave radar 40 and the power-taking device 30, and the power-taking device 30 can also further protect the connection between the receiving connector 430 and the output connector 3231.
