[0031] Currently, there are generally the following technical solutions for adding light emitting function to the appearance of wearable devices:

[0032] 1. Use a luminous watchband. By adding fluorescent materials in the watchband, after a certain amount of light, the fluorescent materials absorb and store a certain amount of energy, and slowly release in a dark environment, achieving the effect of light emission. However, this solution is limited by the afterglow characteristics of the fluorescent material, and the light emission brightness will quickly decay over time, making it difficult to maintain long-term high-brightness light emission.

[0033] 2. Emit light through the watchband or display screen. The watchband has a light-emitting effect by adding LEDs and light guide materials in the watchband, or by controlling the screen to always be on to present a light-emitting effect. However, this solution requires long-term power consumption, which puts a heavy burden on the battery life of the wearable device.

[0034] 3. Add strong reflective materials to the surface of the watchband. When external light shines, the watchband emits light and produces local bright light, which serves as an indicator. However, this solution must be effective under external light.

[0035] In summary, to solve the technical problem that the prior art cannot emit high-brightness light for a long time with low power consumption, the present embodiment provides a wearable device. As shown in Figure 1 Figure 1 A structural diagram of a wearable device 1 provided by the present embodiment, including a device main body 2, a fluorescent component 3, and a light-emitting component 4. The fluorescent component 3 and the light-emitting component 4 are arranged outside the device main body 2, and the light-emitting surface of the light-emitting component 4 faces the fluorescent component 3.

[0036] The wearable device 1 provided by the present embodiment includes a device main body 2, a fluorescent component 3, and a light-emitting component 4. The device main body 2 is the core component of the wearable device 1, and generally includes a watch case, a circuit board, a display interface, a communication module, and a power module, etc. for realizing the logical computing function, measurement function, and display function of the wearable device 1. For example, when the wearable device 1 is a smart watch, the device main body 2 is the watch main body. The device main body 2 has a fluorescent component 3 outside, which is made of fluorescent material. After a certain amount of light, the fluorescent material in the fluorescent component 3 absorbs and stores a certain amount of energy, and slowly releases the energy in a dark environment, so that the fluorescent component 3 has a light-emitting effect in a dark environment. The arrangement of the fluorescent component 3 outside the device main body 2 in the present embodiment can be arranged according to actual needs, for example, the fluorescent component 3 can be arranged on the frame around the device main body 2, or the fluorescent component 3 can be wrapped outside the device main body 2, etc. The arrangement of the fluorescent component 3 is not limited in the present embodiment.

[0037] ​In addition, in the embodiment, the light emitting component 4 is arranged outside the device body 2, and the light emitting surface of the light emitting component 4 faces the fluorescent component 3, so that when the light emitting component 4 emits light, the fluorescent component 3 can receive the bright light. The position of the light emitting component 4 can also be arranged according to actual needs. For example, the light emitting component 4 and the fluorescent component 3 can be arranged in contact, for example, the light emitting component 4 is arranged at the contact position of the fluorescent component 3 and the device body 2, and the light emitting surface of the light emitting component 4 is in contact with the fluorescent component 3. The light emitting component 4 and the fluorescent component 3 can also be arranged in non-contact, for example, the light emitting component 4 is arranged at the non-contact position of the fluorescent component 3 and the device body 2, and the light emitting surface of the light emitting component 4 faces the fluorescent component 3 without being in contact with the fluorescent component 3. In addition, in the embodiment, the electric energy of the light emitting component 4 can be provided by the device body 2, and the light emitting component 4 can draw electric energy from the inside of the device body 2 by using a wire.

[0038] The device body 2 is used to control the light emitting component 4 to emit light when the preset charging condition is met, so as to charge the fluorescent component 3.

[0039] In the embodiment, the light emitting component 4 is controlled by the device body 2. Specifically, the device body 2 is used to control the light emitting component 4 to emit light when the preset charging condition is met, so as to replenish the energy of the fluorescent material during the attenuation of the light emitting luminance of the fluorescent material, so that the light emitting luminance of the fluorescent material can be maintained at a high level, and the fluorescent component 3 can continuously emit bright light in dark light conditions. The charging condition needs to be set by the user in the device body 2 in advance, for example, the user can set the charging condition as controlling the light emitting component 4 to emit light when a preset time length is reached, so that the device body 2 can periodically control the light emitting component 4 to emit light. In another embodiment, the user can also set the charging condition as controlling the light emitting component 4 to emit light within a preset time range, so that when the time reaches the preset time range, the device body 2 controls the light emitting component 4 to emit light. In the embodiment, the device body 2 does not need to control the light emitting component 4 to emit light at all times by setting the charging condition, which saves the power consumption of the device body. In an embodiment, the user can also increase the pattern design on the surface of the fluorescent component 3, so that the appearance of the fluorescent component 3 in the light emitting state has better expressiveness. In addition, the fluorescent component 3 can also be spliced by using fluorescent materials with different light emitting colors, so that the fluorescent component 3 can emit multiple colors of fluorescent effects.

[0040] The wearable device of the embodiment of the present application has the characteristics of high brightness, low power consumption and long duration of the light-emitting function. The embodiment of the present application solves the technical problem that the wearable device cannot emit high-brightness light for a long time with low power consumption in the prior art.

[0041] On the basis of the above embodiment, the light-emitting component 4 comprises at least one LED, and each LED is electrically connected to the control circuit inside the device main body 2.

[0042] In one embodiment, the light-emitting component 4 can select a light-emitting diode (LED). Each LED is electrically connected to the control circuit inside the device main body 2, so that the device main body 2 can control the LED to emit light through the internal control circuit and provide power for the LED. It should be further pointed out that the LED in this embodiment should select light containing the wave band of the fluorescent material, for example, using strontium aluminate 490 nm fluorescent material, or selecting a yellow-green LED or a white light LED as the light source. In addition, the number of LEDs in this embodiment can be set according to actual needs, and the number of LEDs is not specifically limited in this embodiment.

[0043] As described above, the embodiment of the present application uses an LED as the light-emitting component. The LED control circuit is simple, and the LED has the characteristics of energy saving, environmental protection, good color rendering and high response speed. In addition to realizing the light-emitting function, the cost and power consumption can be reduced.

[0044] On the basis of the above embodiment, the fluorescent component 3 is a watchband or a transparent shell doped with a fluorescent material.

[0045] In one embodiment, the fluorescent component 3 can be a watchband or a transparent shell doped with a fluorescent material. When the fluorescent component 3 is a transparent shell, the transparent shell can wrap the device main body 2 inside and not wrap the side of the device main body 2 that interacts with the user. In one embodiment, the wearable device 1 is a smart watch. Taking the smart watch as an example, as shown in Figure 2 Figure 2 ​The structure diagram of the smart watch is shown in the figure, the device body 2 is the watch body, the transparent shell is wrapped in the inside of the watch body, and the display screen of the watch body is not wrapped, the transparent shell is connected with the watchband 5, the light emitting component 4 arranged between the transparent shell and the watch body is LED, and the light emitting surface of the LED faces the transparent shell. When the user sets the charging condition on the watch body, the watch body can control the LED to emit light when the charging condition is triggered, so as to charge the fluorescent material of the transparent shell, so that the transparent shell can emit light in the dark light condition. In another embodiment, when the fluorescent component 3 is the watchband 5, the entire watchband 5 has a light emitting function at this time. Since the area of the watchband 5 is large, in order to make the entire watchband 5 emit light, the number of LEDs on the side of the watchband 5 can be appropriately increased, as shown in Figure 3 so that the entire watchband 5 can emit light. In another embodiment, a circuit can also be added inside the watchband 5, so as to arrange the LEDs inside the watchband 5, so that the light emitting effect of the watchband 5 is more uniform.

[0046] The above, in the embodiment of the present application, the fluorescent component can be a watchband or a transparent shell doped with a fluorescent material, the user can select the watchband to cooperate with the transparent shell, or directly select the watchband made of a fluorescent material, so as to flexibly meet the individual needs of the user.

[0047] On the basis of the above embodiment, the fluorescent material is a light storage type long afterglow fluorescent material, the material of the transparent shell is any one of polymethyl methacrylate, polycarbonate, polyethylene terephthalate, polypropylene, polyvinyl chloride, acrylonitrile-styrene-diene copolymer, thermoplastic polyurethane elastomer rubber, polystyrene, polysulfone and transparent nylon, and the material of the watchband 5 is thermoplastic polyurethane elastomer rubber or polypropylene.

[0048] In one embodiment, the fluorescent material is a light storage type long afterglow fluorescent material, and its chemical composition is generally strontium aluminate or silicate doped with rare earth materials, and the chemical formula and related parameters are shown in Table 1:

[0049] Light emitting material Light emitting color Light emitting spectral wavelength / nm Afterglow time / min BaAl2O4:Eu, Dy Blue-green 496 120 CaAl204:Eu, Nd Blue-violet 446 1000 Sr4Al 14 O 25 : Eu, Dy Blue-green 490 2000 [Ca1-xSrx]Al2O4:Eu,Dy Yellow-green 520 4000 [Ca1-xSrx]SiO3:Eu Blue 469 2000 [Y2O2S:Eu, TI 4+ , Mg 2+ ]]> Red 626 500 CaTiO3:Pr 3+ ]] Red 613 40

[0050] Table 1

[0051] The light storage type long afterglow fluorescent material is excited by light for a certain period of time, absorbs light energy and converts it into chemical energy for storage. When the light storage type long afterglow fluorescent material is in a dark light environment, the stored chemical energy is converted into light energy and released, showing a fluorescent effect and maintaining a long afterglow.

[0052] For the transparent shell, its material can be any one selected from polymethylmethacrylate (PMMA), polycarbonate (PC), polyethylene terephthalate (PET), polypropylene (PP), polyvinylchloride (PVC), acrylonitrile butadiene styrene (ABS), thermoplastic polyurethane (TPU), polystyrene (PS), polysulfone (PSF) and transparent nylon. In addition, the watchband 5 needs to have a certain flexibility, and the material can generally be selected from thermoplastic polyurethane (TPU) or polypropylene (PP) and the like.

[0053] On the basis of the above-mentioned embodiments, the charging condition includes:

[0054] The device main body is in an information receiving state or a use state.

[0055] In an embodiment, the user can preset the charging condition as the device main body 2 being in an information receiving state or a use state. The information receiving state refers to a state in which the device main body 2 receives external information, for example, the device main body 2 receives information notification or incoming call, etc. The use state refers to a state in which the device is being used by the user, for example, the screen of the device main body 2 is lighted up by the user, etc. When the device main body 2 is in the information receiving state or the use state, the device main body 2 can control the light-emitting component 4 to emit light, thereby charging the light-emitting component 3. For example, when the smart watch receives the notification of the application program, or the user is interacting with the smart watch through the screen of the smart watch, the watch main body of the smart watch can control the LED to emit light, thereby charging the light-emitting component 3. At this time, the light emitted by the LED also has the function of information reminding or decoration.

[0056] In the embodiment of the present application, the user can set the charging condition as the device body being in the information receiving state or the use state in advance, so that when the device body is in the information receiving state or the use state, the device body can control the light-emitting component to emit light to charge the fluorescent component. The device body does not need to control the light-emitting component to emit light at all times, thereby saving the power consumption of the device body, maintaining the luminance of the fluorescent component at a high level, and enabling the fluorescent component to emit light for a long time. Meanwhile, the light emitted by the light-emitting component has an information reminding function when the device body is in the information receiving state and has a decoration function when the device body is in the use state, thereby greatly improving the user experience.

[0057] On the basis of the above embodiment, the charging condition comprises:

[0058] The device body receives the light-emitting control instruction.

[0059] In another embodiment, the user can also set the charging condition as the device body 2 controlling the light-emitting component 4 to emit light when the device body 2 receives the light-emitting control instruction in advance. For example, the user can send the device control instruction to the device body through the screen of the smart watch. When the user needs to send the light-emitting control instruction to the device body, the user can call up the light-emitting control interface on the screen, as shown in FIG. 2. Figure 4 After the user clicks the “Confirm” button, the control instruction can be sent to the device body. In another embodiment, the user can also send the light-emitting control instruction to the device body 2 by operating the physical button on the upper side of the device body. For example, the user can send the light-emitting control instruction to the device body by double-clicking the button 7 in FIG. 3. Figure 2 It can be understood that in the embodiment, the user can send the light-emitting control instruction to the device body 2 in the manner as required, which is not limited in the embodiment.

[0060] In the embodiment of the present application, the user can set the charging condition as the device body receiving the light-emitting control instruction in advance, so that the user can charge the fluorescent component according to subjective needs, thereby improving the flexibility of charging the fluorescent component.

[0061] On the basis of the above embodiment, the device body 2 is further provided with a first light intensity sensor, and the first light intensity sensor is used to collect the first light intensity of the environment. The device body 2 is further used to acquire the first light intensity collected by the first light intensity sensor.

[0062] The charging condition comprises:

[0063] The first light intensity is less than a preset first light intensity threshold.

[0064] In one embodiment, the device body 2 is further provided with a first light intensity sensor, wherein the first light intensity sensor is electrically connected with the internal control circuit of the device body 2, so that the device body 2 can supply power for the first light intensity sensor and transmit data with the first light intensity sensor. The first light intensity sensor is used to collect the first light intensity of the environment where the device body 2 is located, and transmit the collected first light intensity to the device body 2.

[0065] When the device body 2 is provided with the first light intensity sensor, the user can set the charging condition as the first light intensity being less than the preset first light intensity threshold, so that the device body 2 can control the light emitting component 4 to emit light to charge the fluorescent component 3 when the first light intensity of the surrounding environment is less than the preset first light intensity threshold. In one embodiment, the user can set the first light intensity threshold according to the light intensity in the dark environment, and set the charging condition as the first light intensity being less than the preset first light intensity threshold in the watch body of the smart watch. When the watch body determines that the first light intensity of the current environment is less than the preset first light intensity threshold, the watch body can determine that the current environment is in the dark environment, and the watch body can periodically control the LED to emit light to charge the fluorescent component 3.

[0066] In the embodiment of the present application, when the device body is provided with the first light intensity sensor, the user can set the charging condition as the first light intensity being less than the preset first light intensity threshold, so that the device body can actively charge the fluorescent component when the device body is in the dark environment. The embodiment of the present application does not need the device body to control the light emitting component to emit light all the time, which saves the power consumption of the device body, and can maintain the luminance of the fluorescent component at a high level, so that the fluorescent component can emit light for a long time.

[0067] On the basis of the above-mentioned embodiment, the device body 2 is further provided with a second light intensity sensor, and the second light intensity sensor is used to collect the second light intensity of the fluorescent component 3. The device body 2 is further used to obtain the second light intensity collected by the second light intensity sensor.

[0068] The charging condition includes:

[0069] The second light intensity is less than a preset second light intensity threshold.

[0070] In another embodiment, the device body 2 is further provided with a second light intensity sensor, wherein the second light intensity sensor is electrically connected with the internal control circuit of the device body 2, so that the device body 2 can supply power for the second light intensity sensor and transmit data with the second light intensity sensor. The second light intensity sensor is used to collect the second light intensity of the fluorescent component 3, and transmit the second light intensity to the device body 2.

[0071] When the second light intensity sensor is arranged on the device body 2, the user can set the charging condition as the second light intensity being less than a preset second light intensity threshold, so that when the second light intensity of the fluorescent component 3 is less than the preset second light intensity threshold, the device body 2 can control the light-emitting component 4 to emit light to charge the fluorescent component 3, so that the luminance of the fluorescent component 3 can be maintained at a high level, and the fluorescent component 3 can emit light for a long time. The second light intensity threshold can be set according to actual needs, and the specific value of the second light intensity threshold is not limited in the embodiment. In an embodiment, the user can set the second light intensity threshold to 300 mcd / m 2 and set the charging condition as the second light intensity being less than a preset second light intensity threshold in the watch body of the smart watch, so that when the watch body determines that the second light intensity of the fluorescent component 3 is less than 300 mcd / m 2 , the watch body can determine that the luminance of the fluorescent component 3 is low and needs to be charged, and the watch body can periodically control the LED to emit light to charge the fluorescent component 3.

[0072] In the embodiment of the present application, when the second light intensity sensor is arranged on the device body, the user can set the charging condition as the second light intensity being less than a preset second light intensity threshold, so that when the luminance of the fluorescent component is low, the device body can actively charge the fluorescent component. The embodiment of the present application does not need the device body to control the light-emitting component to emit light all the time, which saves the power consumption of the device body, maintains the luminance of the fluorescent component at a high level, and enables the fluorescent component to emit light for a long time.

[0073] In an embodiment, the fluorescent component 3 includes a light guide substrate 6, which is used to uniformly transmit the light emitted by the light-emitting component 4 to the fluorescent component 3.

[0074] In an embodiment, the fluorescent component 3 includes a light guide substrate 6, which is used to uniformly transmit the light emitted by the light-emitting component 4 to the fluorescent component 3, so that the luminance of the light emitted by the fluorescent component 3 at different positions is uniform. For example, as shown in Figure 5 , the fluorescent component 3 of the smart watch further includes a light guide substrate 6, and the light emitted by the LED is uniformly transmitted to the fluorescent component 3 by the light guide substrate 6, so that the fluorescent component 3 emits light uniformly at each position.

[0075] In the above embodiment of the present application, the light guide substrate is arranged on the fluorescent component, so that different positions of the fluorescent component can emit light uniformly, and the appearance and use experience of the wearable device are improved.

[0076] In the above, the embodiment of the present application sets the light-emitting component and the fluorescent component in the wearable device, controls the light-emitting component to emit light when the device main body meets the preset charging condition, thereby charging the fluorescent material of the fluorescent component. In the embodiment of the present application, the device main body does not need to control the light-emitting component to emit light all the time, thereby saving the power consumption of the device main body, maintaining the luminance of the fluorescent component at a high level, and enabling the fluorescent component to emit light for a long time.
