Technical Field
[0001] This utility model relates to the field of power supply technology for wearable devices, and in particular to a micro-electric power supply device for wearable devices. Background Technology
[0002] Currently, wearable devices (such as smartwatches and health monitoring devices) generally face technical bottlenecks in power supply and outdoor energy replenishment during practical applications. Traditional wearable devices mostly rely on built-in batteries for power. When users are outdoors and the battery is low, they often need to carry additional charging equipment or find a charging port, resulting in poor convenience. Furthermore, the solar charging structures of existing devices are usually designed as fixed structures, which are limited by the area exposed to sunlight, resulting in low energy collection efficiency and difficulty in providing sufficient power to devices in outdoor environments. Therefore, this application proposes a micro-power supply device that can efficiently utilize solar energy, has a flexible structure, and provides stable power supply to solve the problem of power shortage for existing wearable devices when used outdoors.

[0025] Example 1
[0026] Please see Figure 1-6 A micro-electric power supply device for wearable devices includes a housing 10 and an end cap 20 fixedly connected to the top of the housing 10;
[0027] Specifically, the front and rear sides of the outer casing 10 are respectively equipped with a watch strap 13 and a watch strap 21. The top of the watch strap 11 is fixedly connected to a buckle 12. The watch strap 23 has multiple evenly distributed limiting holes 14. The buckle 12 matches the limiting holes 14 to facilitate the user wearing the device. The end cover 20 has a through mounting slot in the middle, which houses the display screen 21 for displaying data such as time. The top edge of the end cover 20 has a placement slot, which houses a solar panel 22. The solar panel ensures that the device has sufficient power to maintain normal operation when the user is away. A transparent plastic cover is fixedly connected to the top outer wall of the placement slot to provide safety protection for the solar panel 22.
[0028] A through-slot is provided on one side of the outer casing 10, and a slide plate 41 is provided inside. A mounting slot is provided on the top of the slide plate 41, and a second solar panel 42 is installed inside. A transparent plastic cover is also fixedly connected to the top outer wall of the mounting slot, which can provide safety protection for the second solar panel 42.
[0029] A baffle 40 is fixedly connected to the side of the slide plate 41 away from the outer shell. After the slide plate 41 is pushed into the outer shell 10, the baffle 40 is tightly attached to the outer wall of the outer shell 10. A magnetic piece is glued and fixed to the side of the baffle 40 close to the slide plate 41. A metal piece (such as an iron piece) that attracts the magnetic piece is fixedly connected to the outer wall of the outer shell 10 on the side that is in contact with the baffle 40. This facilitates the quick removal of the slide plate 41 from the outer shell 10 when the baffle 40 is removed later.
[0030] Limiting grooves 43 are provided on the front and rear sides of the slide plate 41. Limiting blocks 44 are slidably connected in the limiting grooves 43. The limiting blocks 44 are fixedly connected to the inner walls of the front and rear sides of the slide groove, respectively, to limit the slide plate 41 and prevent the slide plate 41 from being completely pulled out of the outer shell 10.
[0031] When outdoors (in good sunlight), the user can pull the slide plate 41 out of the outer casing 10 through the baffle 40. The second solar panel 42, in conjunction with the first solar panel 22, can provide power to the device to the maximum extent to ensure the normal use of the device.
[0032] When the slide plate 41 is pulled outward, the limiting block 44 prevents the slide plate 41 from being completely pulled out, but the length of the pulled-out slide plate 41 is enough to expose the entire solar panel 42.
[0033] A control circuit board 30 is fixedly connected to the inner wall of the bottom of the outer casing 10. It is located below the slide plate 41. The control circuit board 30 is connected in series with the controller 33 through wires. The controller 33 is a microcontroller, such as a PLC controller, which serves as the main control unit. The control circuit board 30 is connected in series with the lithium battery pack 31 through wires to provide power for the operation of the control circuit board 30, etc. The lithium battery pack 31 is connected in parallel with the first solar panel 22 and the second solar panel 42 through wires respectively. The solar panels can be used to replenish the power of the lithium battery pack 31.
[0034] Since the second solar panel 42 will be pulled and moved within a small range, in order to prevent the wires between the second solar panel 42 and the lithium battery pack 31 from breaking, an extra length can be reserved to provide a certain length for the movement of the second solar panel 42.
[0035] The lithium battery pack 31 is composed of multiple small lithium batteries connected in series, which has a high energy density and provides a stable power supply for the equipment.
[0036] A DC-DC converter 32 is also provided on the line connecting the lithium battery pack 31 to the first solar panel 22 and the second solar panel 42. When the voltage of the solar panel and the voltage of the lithium battery do not match, the voltage is stepped down by the DC-DC converter to ensure safe charging.
[0037] The controller 33 is also connected in series with the display screen 21 via a wire to output the received human heart rate data to the display screen 21 for display so that the user can observe it.
[0038] The bottom outer wall of the outer casing 10 is equipped with a heart rate monitoring terminal 15, which is connected in series with the controller 33 via a wire to realize human heart rate monitoring;
[0039] The heart rate monitoring terminal 15 uses a similar technology to the heart rate monitoring on existing smartwatches. Specifically, it mainly uses photoplethysmography (PPG). It uses light to illuminate the skin and detects the changes in blood absorption of light to sense the pulse. An LED light (usually green light) on the bottom of the casing illuminates the skin. After the light penetrates the skin tissue, it is absorbed by the blood. A photodiode receives the reflected or transmitted light signal, converts it into an electrical signal, and forms a periodic pulse wave (PPG signal). This signal is transmitted to the controller to calculate the heart rate and output it to the display screen for display.
[0040] A charging hole is reserved on the side wall of the outer casing 10 where the sliding groove is not opened, which can be used for charging the lithium battery pack 31 later.
[0041] In actual operation of the embodiments of this application:
[0042] The device is worn on the user's wrist via strap 11 and strap 2 13. The heart rate monitoring terminal 15 can monitor the user's heart rate changes in real time. When the user goes out without a backup power source and the device's battery is low, the device can be placed under sunlight and the solar panel 22 on the end cover can be used to replenish the device's power. The slide plate 41 can also be pulled out from the outer casing 10 through the baffle 40. The solar panel 2 42 works in conjunction with the solar panel 22 to provide maximum power to the device and ensure its normal use.
[0043] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. For those skilled in the art, various modifications and variations are possible with this utility model. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
