[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0022] like Figure 1 The diagram shown is a schematic of a desktop charging device provided in an embodiment of the present invention. This desktop charging device can wirelessly charge smartphones and other devices, and can also generate circadian rhythm light to improve sleep quality. The desktop charging device of this embodiment includes a wireless charging pad 10, a base 20, a support rod 30, and a control module. The support rod 30 is connected between the base 20 and the wireless charging pad 10, thereby causing the wireless charging pad 10 to protrude above the base 20.

[0023] Combination Figure 2 As shown, the wireless charging pad 10 includes a first housing 11, a first wireless charging module 12, and a light-emitting module 13. The first housing 11 is generally plate-shaped (e.g., Figure 2 As shown in the circular plate shape, in one embodiment of this utility model, the first housing 11 can be specifically assembled from a disc-shaped body 112 and a top plate 111, and the disc-shaped body 112 and the top plate 111 can be processed from hard materials such as metal or plastic. A charging platform for placing a device to be charged (e.g., a smartphone) is formed on the upper surface of the first housing 11 (e.g., the top plate 111). A first wireless charging module 12 is installed inside the first housing 11 and adjacent to the charging platform. A light-emitting module 13 is installed on the surface of the first housing 11 facing away from the charging platform, and the light-emitting module 13 includes at least one of the following: a first light emitter for generating 620-850nm light and a second light emitter for generating 400-450nm light. That is, the light-emitting module 13 can include only one of the first light emitter or the second light emitter, or it can include both the first light emitter and the second light emitter simultaneously.

[0024] Those skilled in the art will understand that the charging platform described above is a support for placing the device to be charged, which can be a flat surface or have a groove adapted to the shape of the device to be charged; the first wireless charging module 12 includes a transmitting coil, which generates a changing magnetic field when energized, and the first wireless charging module 12 may also include a magnetic element to cooperate with a magnetic element on the device to be charged placed on the charging platform to prevent the device to be charged from slipping during charging; the light-emitting module 13 may include a lampshade 132 to soften the light from the first light-emitting element and the second light-emitting element. The first wireless charging module 12 described above can adopt a structure commonly used in the art, and will not be described in detail here.

[0025] The weight of the aforementioned base 20 is greater than the weight of the wireless charging pad 10; for example, the weight of the base 20 can be increased by adding counterweights. Figure 5 , Figure 8 As shown, the base 20 includes a second housing, and a receiving cavity 24 is formed within the second housing. A power module 22 is installed within the receiving cavity 24. The power module 22 is the power source for the desktop charging device, used to supply power to the first wireless charging module 12, the light-emitting module 13, and the control module, etc. Specifically, the power module 22 can be a power adapter, which can convert externally input AC power into DC power before outputting it. In practical applications, the power module 22 can also be a DC-DC converter module, which can convert the externally input DC power into voltage before outputting it; or, the power module 22 may also consist of a battery and a charging / discharging circuit. The power module 22 can adopt conventional solutions in the art, which will not be described in detail here.

[0026] The first end of the aforementioned support rod 30 is connected to the second housing, and the second end of the support rod 30 is hinged to the edge of the first housing 11 via a horizontal pin. That is, the support rod 30 connects the base 20 and the wireless charging pad 10, and the wireless charging pad 10 can rotate relative to the second end of the support rod 30 (i.e., rotate around the horizontal pin), thereby adjusting the pitch angle of the light-emitting module 13 on the lower surface of the first housing 11. When the wireless charging pad 10 rotates relative to the support rod 30 so that the light-emitting module 13 faces the base 20, there is a gap between the light-emitting module 13 and the upper surface of the base 20. The support rod 30 also has a cable passage, through which the first wireless charging module 12 is electrically connected to the power module 22 via a first cable passing through the cable passage. This prevents exposed cables while the power module 22 in the base 20 supplies power to the first wireless charging module 12 in the wireless charging pad 10.

[0027] The control module is electrically connected to the light-emitting module 13, and the first and second light-emitting elements in the light-emitting module 13 generate rhythmic light under the control of the control module. This rhythmic light refers to a specific type of light that can influence or regulate the human body's biological clock (circadian rhythm). The control module simulates the changing patterns of natural sunlight by controlling the luminous intensity, color temperature, spectral composition, and irradiation time of the first and second light-emitting elements, thereby synchronizing with the body's internal physiological rhythms and promoting health. The control module can adjust the luminous intensity and color temperature of the first and second light-emitting elements using pulse width modulation signals. Specifically, the control module can use conventional methods in the art to control the first and second light-emitting elements to generate rhythmic light, which will not be elaborated here. When the light-emitting module 13 includes only the first light-emitting element, the control module can control the light-emitting module to generate light that helps with sleep; when the light-emitting module 13 includes only the second light-emitting element, the control module can control the light-emitting module to generate light that wakes you up from sleep; when the light-emitting module 13 includes both the first light-emitting element and the second light-emitting element, the control module can control the light-emitting module to first generate light that helps with sleep, and then generate light that wakes you up from sleep.

[0028] The aforementioned desktop charging device, by hinged a wireless charging pad 10 to the top of a support rod 30 fixed to a base 20, and placing a first wireless charging module 12 below the charging platform on the upper surface of the wireless charging pad 10, and a light-emitting module 13 on the lower surface of the wireless charging pad 10, and controlling the first and second light-emitting elements in the light-emitting module 13 to emit light through a control module, can generate rhythmic light while achieving wireless charging. Furthermore, by rotating the wireless charging pad 10 relative to the support rod 30, the illumination angle of the light-emitting module 13 can be adjusted. For example, the light-emitting module 13 can be oriented towards the base 20 for wireless charging of smartphones, or it can be oriented away from or towards the side of the base 20 to facilitate sleep, adapting to different usage scenarios. Simultaneously, since the weight of the base 20 is greater than the weight of the wireless charging pad 10, the entire desktop charging device can remain stable when adjusting the tilt angle of the wireless charging pad 10.

[0029] Combination Figure 2 , Figure 4 , Figure 8 As shown, in one embodiment of this utility model, the control module includes a first circuit board 23 and a first operation button 26. The first circuit board 23 has a first trigger switch 232. The light-emitting control circuit 231 is electrically connected to the power module 22, and the first trigger switch 232 is electrically connected to the light-emitting control circuit. The light-emitting module 13 is electrically connected to the light-emitting control circuit 231, and the light-emitting control circuit 231 controls the first light-emitting element and the second light-emitting element in the light-emitting module 13 to emit light when the first trigger switch 232 is triggered by the first operation button 26.

[0030] As will be understood by those skilled in the art, the aforementioned light-emitting control circuit 231 may be composed of electronic components soldered to the surface of the first circuit board 23 and circuitry within the first circuit board 23 for connecting the electronic components, while the first trigger switch 232 is composed of a switching element soldered to the surface of the first circuit board 23. The first operation button 26 is exposed on the surface of the second housing of the base 20. By clicking (or pressing) the first operation button 26, the user can cause the first operation button 26 to actuate or change the state of the first trigger switch 232. The light-emitting control circuit 231 can determine whether the first trigger switch 232 has been triggered by detecting its actuation or state, thereby controlling the light emission of the light-emitting module 13. Specifically, the aforementioned first circuit board 23 (including the light-emitting control circuit 231 and the first trigger switch 232) and the first operation button 26 may employ conventional techniques in the art, which will not be elaborated upon here.

[0031] Combination Figure 2 , Figure 4 As shown, in one embodiment of this utility model, the light-emitting module 13 includes a second circuit board 131. The first light-emitting element and the second light-emitting element are respectively composed of light-emitting diodes (LEDs), and the first light-emitting element and the second light-emitting element are respectively fixed on the same surface of the second circuit board 131. For example, the first light-emitting element can be distributed in a dot matrix on the surface of the second circuit board 131, and each second light-emitting element is arranged adjacent to a first light-emitting element. Correspondingly, the second circuit board 131 has a first driving circuit 1311 and a second driving circuit 1312. The first light-emitting element is electrically connected to the first driving circuit 1311 and emits light under the drive of the first driving circuit 1311, and the second light-emitting element is electrically connected to the second driving circuit 1312 and emits light under the drive of the second driving circuit 1312. The first driving circuit 1311 and the second driving circuit 1312 can both adopt conventional structures in the art, and will not be described in detail here.

[0032] The light-emitting control circuit 231 is electrically connected to the first driving circuit 1311 and the second driving circuit 1312 respectively. When the first trigger switch 232 is triggered by the first operation button 26, the first light-emitting body and the second light-emitting body generate rhythmic light and illumination light by controlling the first driving circuit 1311 and the second driving circuit 1312. The illumination light can be used for reading light, night light, supplementary light, etc. For example, when the first operation button 26 is pressed once, it triggers the first trigger switch 232 to generate a first trigger signal. The light-emitting control circuit 231 outputs the first driving circuit 1311 and the second driving circuit 1312 according to the first trigger signal, causing the first light emitter and the second light emitter to generate illumination light. When the first light emitter and the second light emitter output illumination light, the first operation button 26 is pressed, triggering the first trigger switch 232 to generate a second trigger signal. The light-emitting control circuit 231 outputs the first driving circuit 1311 and the second driving circuit 1312 according to the second trigger signal, causing the first light emitter and the second light emitter to generate rhythmic light. When the first light emitter and the second light emitter output rhythmic light, the first operation button 26 is pressed, triggering the first trigger switch 232 to generate a third trigger signal. The light-emitting control circuit 231 outputs the first driving circuit 1311 and the second driving circuit 1312 according to the third trigger signal, causing both the first light emitter and the second light emitter to turn off.

[0033] In one embodiment of this utility model, the light-emitting module 13 includes both a first light-emitting element and a second light-emitting element. The control module may further include a second operation button 27. Correspondingly, the first circuit board 23 has a second trigger switch 233 electrically connected to the light-emitting control circuit 231. The light-emitting control circuit 231 includes a timing element, and the timing duration of the timing element is adjusted by triggering the second trigger switch 233 and the second operation button 27. Specifically, the second operation button 27 can be a knob, and correspondingly, the second trigger switch 233 is an adjustable resistor. By rotating the second operation button, the resistance value of the second trigger switch 233 can be adjusted. When the first and second light emitters emit rhythmic light, the light emission control circuit 231 sets the timing duration of the timing element based on the resistance value of the second trigger switch 233. For example, after the timing element reaches its timing duration (starting from emitting sleep-inducing 620-850nm light), the light emission control circuit 231 controls the first and second light emitters to emit sleep-awakening 400-450nm light. Furthermore, the control module can also control the light emission intensity of the first and second light emitters to change over time. For example, during the timing process, the light emission intensity of the second light emitter can be gradually decreased, and then gradually increased as the timing duration approaches, while simultaneously controlling the light emission intensity of the first light emitter to gradually decrease. In addition, when the first and second light emitters emit illumination light, the light emission control circuit 231 can also adjust the brightness of the first and second light emitters based on the resistance value of the second trigger switch 233.

[0034] like Figure 8 As shown, in one embodiment of this utility model, the first circuit board 23 is installed in the accommodating cavity 24 of the base. The light-emitting module 13 is electrically connected to the light-emitting control circuit 231 on the first circuit board 23 via a second cable passing through the cable channel. The first operation button 26 and the second operation button 27 are respectively exposed on the surface of the second housing (adjacent to the first circuit board 23). This structure facilitates the operation of the first operation button 26 and the second operation button 27. Of course, in practical applications, the first circuit board 23 can also be installed on the wireless charging pad 10, and the first operation button 26 and the second operation button 27 can be exposed on the surface of the first housing 11.

[0035] like Figure 5 As shown, in one embodiment of this utility model, the side surface of the second housing has a charging interface 28 electrically connected to the power module 22. This charging interface 28 can be a DC input port (in which case the power module 22 does not require a rectifier circuit) or an AC input port (in which case the power module 22 must include a rectifier circuit). Furthermore, the side surface of the second housing also has at least one DC output interface 29. A second wireless charging module 25 is located below the top surface of the second housing, and the DC output interface 29 and the second wireless charging module 25 are respectively electrically connected to the power module 22. The second wireless charging module 25 can wirelessly charge wireless Bluetooth headsets, smartwatches, etc., and by connecting the charging cable to the DC output interface 29, wired charging can be performed on smartphones, etc. This structure facilitates the desktop charging device to charge more electronic devices.

[0036] In one embodiment of this utility model, the first end of the support rod 30 is hinged to the edge of the second housing, and when the support rod 30 rotates toward the base 20 to its end point and the wireless charging pad 10 rotates toward the base 20 to its end point, the lower surface of the wireless charging pad 10 is parallel to the upper surface of the base 20 (there is a gap between the lower surface of the wireless charging pad 10 and the upper surface of the base 20). At this time, if the desktop charging device is placed at the bedside, the rhythmic light emitted by the first light source and the second light source is relatively soft, which helps with sleep, and the first wireless charging module 12 can also be used to charge smartphones and other devices simultaneously.

[0037] like Figure 5 , Figure 8As shown, in one embodiment of this utility model, the second housing includes a housing body 211, a turntable 212, and a bottom plate 215. A receiving cavity 24 is located inside the housing body 211. The bottom plate 215 is fixed to the bottom of the housing body 211, making the receiving cavity 24 relatively closed. The turntable 212 is located at the top of the housing body 211, and the first end of the support rod 30 is hinged to the edge of the turntable 212. Specifically, the turntable 212 may have a central through hole 2121. The turntable 212 is assembled to the top of the housing body 211 through a pressure cover 213 embedded in the central through hole 2121. The second wireless charging module 25 can be assembled below the pressure cover 213. By rotating the turntable 212, the illumination direction of the light-emitting module 13 can be adjusted. For example, when the desktop charging device is far from the bed, the wireless charging pad 10 can be rotated around the second end of the support rod 30 to a vertical position first, and then the turntable 212 can be rotated to make the light-emitting module 13 face the bed, thereby allowing rhythmic light to illuminate the bed. Specifically, the pressure cap 213 can be fixed to the shell body 211 by screws passing through the fixing hole 2113 on the top surface of the shell body 211, and limit the position of the turntable 212.

[0038] Combination Figure 6 , Figure 7 As shown, in one embodiment of this utility model, the top of the shell body 211 has an annular slide rail 2111 and a plurality of recesses 2112, which are distributed circumferentially along the annular slide rail 2111. Correspondingly, a plurality of first sliding members 214 are mounted on the lower surface of the turntable 212. The plurality of first sliding members 214 are respectively mounted in the mounting grooves 2122 on the lower surface of the turntable 212. Each first sliding member 214 includes a columnar body and a ball bearing mounted on the bottom end of the columnar body by an elastic member. When the turntable 212 is assembled to the top of the shell body 211, the ball bearings of the plurality of first sliding members 214 are embedded in the annular slide rail 2111 and guide the turntable 212 to rotate, and the turntable 212 is positioned by being embedded in the recesses 2112.

[0039] Specifically, in order to maintain the electrical connection between the power module 22 in the accommodating cavity 24 and the first wireless charging module 12 in the wireless charging pad 10 during the rotation of the turntable 212, the top surface of the shell body 211 has an annular conductor, and the annular conductor is electrically connected to the power module 22; correspondingly, the bottom of the support rod 30 has an elastic conductive contact that is electrically connected to the first cable, and the first cable is electrically connected to the power module 22 through the elastic conductive contact and the annular conductor.

[0040] Of course, in practical applications, a limiting strip 2114 can also be set on the top surface of the shell body 211. The limiting strip 2114 allows the turntable 212 to rotate up to 180° in one direction. During the rotation, the first cable in the cable passage of the support rod 30 can be extended or retracted (for example, the first cable can be spring-shaped).

[0041] In addition, such as Figure 3 As shown, the wireless charging pad 10 can be hinged to the second end of the support rod 30 using a hinge 14. The hinge 14 includes two parallel lugs 141, each lug 141 having a pin hole 1411, an arc-shaped groove 1412, and a limiting groove located in the arc-shaped groove 1412. Correspondingly, the second end of the support rod 30 has a horizontal pin 31 and a second sliding member 32. Each second sliding member 32 includes a columnar body and a ball bearing mounted on the end of the columnar body via an elastic member. When the horizontal pin 31 is inserted into the pin hole, the ball bearing of the second sliding member 32 is embedded in the arc-shaped groove 1412, and under the elastic force of the elastic member, the ball bearing is embedded in the limiting groove, thereby achieving rotational limiting of the wireless charging pad 10. With the above structure, the wireless charging pad 10 can be tilted and rotated while remaining stable after rotation.

[0042] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
