The present application provides a wearable electronic device, which may be an intelligent ring 100, an intelligent bracelet, an intelligent watch, or the like. In the embodiment of the application, the wearable electronic device is taken as an example of the intelligent ring 100, and the corresponding structural design is introduced.
Referring to fig. 1, fig. 1 is a scene diagram of a medium worn on a user's hand according to an embodiment of the present application. As shown in fig. 1, the ring 100 includes a solar-powered receiving area thereon that receives solar energy when the ring 100 is worn on a user's hand, and associated components within the solar-powered receiving area convert the solar energy to electrical energy to support the operation of the ring 100.
The structure of the ring 100 according to the embodiment of the present application will be described in detail. Referring to fig. 2 and 3, fig. 2 is a schematic view of an external structure of a ring 100 according to an embodiment of the present application, and fig. 3 is a schematic view of an internal structure of a ring 100 according to an embodiment of the present application. As shown in fig. 2 and 3, the ring 100 includes an annular outer shell 110 and an annular inner liner 120, wherein the inner liner 120 is connected to the inner side of the outer shell 110, the outer shell 110 and the inner liner 120 are connected in a sealing manner, and an accommodating space is formed between the outer shell 110 and the inner liner 120. The receiving space is used to arrange various electronic components inside the ring 100.
Referring to fig. 4, fig. 4 is a schematic diagram of a shell 110 of a ring 100 according to an embodiment of the present application. As shown in fig. 4, the outer shell 110 is provided with a through hole at a position corresponding to the solar energy receiving area, so that solar energy can enter the ring 100. Both ends of the inner side of the housing 110 are provided with rims 112, and the rims 112 are disposed along the circumference of the bottom plate 111 of the housing 110, that is, the rims 112 are also annular. When the inner liner 120 is connected to the outer shell 110, the inner liner 120 is connected to the side frames 112 at two ends of the inner side of the outer shell 110, and the inner liner 120, the side frames 112 of the outer shell 110 and the bottom plate 111 of the outer shell 110 can form a containing space for arranging various electronic components due to the certain height of the side frames 112.
In the embodiment of the present application, the outer shell 110 of the ring 100 may be made of a metal material such as stainless steel or titanium alloy, and when the outer shell 110 is manufactured, a numerical control machine (Computer numerical control machine tools, CNC) may be used to process the outer shell 110 first, so as to manufacture the basic shape of the outer shell 110. To meet the cosmetic requirements of ring 100, the outside of shell 110 may be further processed by a physical vapor deposition (Physical Vapor Deposition, PVD) film-growing process, resulting in a ring 100 that has a high aesthetic appearance.
With continued reference to fig. 2, a transparent cover plate 130 is disposed at a position of the through hole of the outer shell 110, the shape of the cover plate 130 is matched with that of the through hole, and the cover plate 130, the outer shell 110 and the inner liner 120 make the accommodating space be a closed space. By arranging the cover plate 130 at the position of the through hole, the appearance of the ring 100 forms a complete whole, and the accommodating space forms a closed space, so that external impurities are prevented from entering the ring 100 through the through hole, and damage is caused to elements in the ring 100.
Referring to fig. 3, a solar cell panel 140, an energy storage battery 150, a circuit board 160 and an application assembly 170 are provided in the receiving space of the ring 100, wherein the solar cell panel 140 is coupled to the cover plate 130, and the solar cell panel 140 receives light transmitted through the cover plate 130. The cover 130 is made of a material having transparency, and the higher the transparency of the cover 130, the stronger the light received by the solar panel 140 and the more energy received. The circuit board 160 is electrically connected to the solar panel 140, and the energy storage battery 150 and the application assembly 170 are electrically connected to the circuit board 160, respectively. The solar panel 140 converts the received solar energy into electrical energy and supplies the converted electrical energy to the energy storage cell 150 and/or the application assembly 170 through the circuit board 160. The energy storage battery 150 is used to power the application assembly 170 to ensure proper operation of the ring 100. When the electric energy generated by the solar panel 140 is only supplied to the energy storage battery 150, the energy storage battery 150 can be charged, so that the conversion of solar energy into electric energy is realized and stored in the energy storage battery 150, and the cruising ability of the ring 100 is improved. When the electric energy generated by the solar panel 140 is only supplied to the application component 170, the solar energy is directly supplied to the application component 170 after being converted into the electric energy, so that the electric energy consumption of the energy storage battery 150 is reduced. If the electric energy generated by the solar panel 140 is sufficient, the application component 170 may be powered while the energy storage battery 150 is charged, and the surplus electric energy is stored in the energy storage battery 150.
Through setting up solar cell panel 140, when the user wears ring 100 in the open air, solar cell panel 140 can receive certain solar energy and turn into the electric energy for the application subassembly 170 in the ring 100 supplies power, perhaps with the electric energy storage after the conversion in energy storage battery 150, thereby improve the duration of ring 100, reduce the number of times of charging with ring 100 from taking down in the user's hand, improve user's use experience.
It should be noted that, the solar panel 140 in the embodiment of the present application refers to a device capable of converting thermal energy in light into electric energy, and is called as the solar panel 140 in the name of mainly receiving sunlight, but it does not mean that the solar panel 140 can only receive sunlight, other light in nature or light emitted by an electrical appliance (such as a lamp) can also be used as the light source 230 of the solar panel 140, and the solar panel 140 can also receive light other than sunlight and realize photoelectric conversion.
In an embodiment of the present application, reference may be made to fig. 5 for a schematic structural diagram of the cover 130, and fig. 5 is a schematic structural diagram of the cover 130 of the ring 100 according to an embodiment of the present application. As shown in fig. 5, the overall shape of the cover 130 is arc-shaped, and the arc of the cover 130 is determined by the arc of the housing 110. This is because the housing 110 is in a ring shape, the cover 130 is designed to be arc-shaped, and when the cover 130 is matched with the through hole on the housing 110, the cover 130 and the housing 110 can form a complete arc-shaped structure. Taking the case 110 as a circular ring shape as an example, the overall shape of the cover plate 130 is a part of the circular ring shape, so that a complete circular ring shape is formed after the cover plate is matched with the case 110.
Because the housing 110 is provided with the through hole, in order to facilitate the cooperation between the cover 130 and the housing 110, in the embodiment of the present application, the cover 130 is configured in a "convex" shape. Specifically, as shown in fig. 5, the cover 130 includes a first portion 131 and a second portion 132, where the first portion 131 is smaller in size than the second portion 132, and the first portion 131 is connected to the second portion 132, so that the cover 130 has a "convex" shape. That is, a portion of the upper surface of the second portion 132 is covered by the first portion 131, so that the remaining portion of the upper surface of the second portion 132 is annular. The size of the first portion 131 is matched with the size of the through hole on the housing 110, and the thickness of the first portion 131 is equal to the thickness of the housing 110.
When it is necessary to fit the cover 130 with the housing 110, the cover 130 may be installed at the through hole of the housing 110 from the inside of the housing 110. When the cover 130 is coupled to the housing 110, the first portion 131 of the cover 130 is matched with the through hole, and the second portion 132 of the cover 130 is attached to the inner side of the housing 110. Since the size of the first portion 131 is the same as that of the through hole, after the first portion 131 is matched with the through hole, the outer side of the shell 110 is just a complete arc surface, so that external impurities are prevented from entering the ring 100 through the through hole on the shell 110. The size of the second portion 132 is larger than that of the through hole, so that the annular portion formed by the second portion 132 not covered by the first portion 131 is stuck to the inner wall of the housing 110 to perform a limiting function, and meanwhile, the annular portion and the inner wall of the housing 110 can be adhered together in an adhesive manner, so that the cover plate 130 and the housing 110 are fixedly connected. Of course, the side wall of the first portion 131 of the cover 130 and the inner wall of the through hole of the housing 110 may be bonded by glue, so as to improve the connection strength between the cover 130 and the housing 110.
In the embodiment of the present application, since the solar panel 140 needs to receive solar energy from the outside through the cover plate 130, the cover plate 130 needs to be made of a material with good light transmittance. For example, the cover 130 is made of a material having a light transmittance of 90% or more. Specifically, the cover plate 130 may be made of glass, and the transmittance of the glass may reach 95%, so that the solar panel 140 may receive enough sunlight. In addition, the glass has a certain level of wear resistance, and the mohs hardness of the glass can reach 5.5, so that when the user wears the ring 100, even if friction occurs with other objects, the cover plate 130 can be ensured to have a certain wear resistance, and cannot be scratched or damaged easily.
In addition, since the outer side of the cover 130 is often in contact with the outside, for example, the finger, in order to improve the light transmittance of the cover 130, a plating layer may be disposed on the outer side of the cover 130 (i.e., the side of the first portion 131 away from the second portion 132) to improve the fingerprint (ANTI FINGER PRINT, AF) resistance. When the anti-fingerprint coating/plating is provided, a physical vapor deposition (Physical Vapor Deposition, PVD) process can be used for treatment.
Since the cover 130 is made of a transparent material, and the cover 130 is composed of the first portion 131 and the second portion 132, the second portion 132 is larger than the first portion 131. While the first portion 131 and the second portion 132 have a certain thickness, the thickness of the first portion 131 and the thickness of the outer shell 110, however, due to the thickness of the second portion 132, after the cover 130 is matched with the outer shell 110, the internal structure of the ring 100 can be seen through the annular portion of the cover 130 formed by the second portion 132 not covered by the first portion 131, so that the overall aesthetic appearance of the ring 100 is affected. To avoid this, a shielding layer 133 is provided on the side of the second portion 132 remote from the first portion 131.
Referring to fig. 6, fig. 6 is another schematic diagram of a cover 130 of a ring 100 according to an embodiment of the present application. As shown in fig. 6, a shielding layer 133 is disposed on a side of the second portion 132 away from the first portion 131, and the size of the shielding layer 133 is identical to the size of an annular portion formed by the other side of the second portion 132 not covered by the first portion 131. That is, the shielding layer 133 has a ring shape, and the area surrounded by the shielding layer 133 on the second portion 132 matches the size of the bottom surface of the first portion 131. Through setting up shielding layer 133 in the one side that second portion 132 kept away from first portion 131 for after apron 130 and shell 110 cooperation are installed, can't see the inner structure of ring 100 from the external world through the part that sets up shielding layer 133 on apron 130, be favorable to promoting the whole aesthetic property of ring 100. The color of the shielding layer 133 may be the same as that of the solar panel 140, so that the color of the ring 100 may be the same when the ring 100 is seen from the outside through the cover plate 130 to the inside of the ring 100, thereby improving the beauty of the ring 100. Wherein the shielding layer 133 may be formed by printing ink on a side of the second portion 132 of the cover plate 130 remote from the first portion 131. For example, if the entire color of the solar cell panel 140 is black, black ink may be printed as the shielding layer 133.
In an embodiment of the present application, the solar panel 140 is connected to the cover plate 130, so that the solar panel 140 can receive the light transmitted through the cover plate 130. Fig. 7 and fig. 8 may be referred to for a schematic connection structure between the solar panel 140 and the cover plate 130, fig. 7 is a schematic connection structure between the solar panel 140 and the cover plate 130 in the ring 100 according to an embodiment of the present application, and fig. 8 is a schematic connection structure between the solar panel 140 and the cover plate 130 in the ring 100 according to another embodiment of the present application.
As shown in fig. 7 and 8, the solar panel 140 is connected to one side of the cover plate 130, and the solar panel 140 and the first portion 131 are located at both sides of the second portion 132, respectively. When the cover plate 130 is coupled at the through hole of the case 110, the solar cell panel 140 coupled inside the cover plate 130 (on the side located inside the ring 100) may receive the light transmitted through the through hole and the cover plate 130, and when the solar cell panel 140 is disposed, the size of the solar cell panel 140 may be the same as the size of the through hole, that is, the same as the size of the first portion 131. Of course, the size of the solar panel 140 may be larger than the size of the through hole. With this arrangement, it is possible to achieve that the light that reaches the inside of the ring 100 through the through hole can be entirely received by the solar cell panel 140, making full use of the light that enters the inside of the ring 100. In the embodiment of the present application, as shown in fig. 7, the size of the solar cell panel 140 is equal to the size of the first portion 131 or slightly larger than the size of the first portion 131. And the position of the solar cell panel 140 corresponds to the position of the first portion 131 of the cap plate 130, thereby realizing that the position of the solar cell panel 140 corresponds to the position of the through hole.
In the embodiment of the present application, the solar panel 140 is a flexible panel, and when the solar panel 140 is connected to the cover plate 130, the shape of the solar panel 140 is the same as the shape of the cover plate 130, and is also arc-shaped. The curvature of the solar panel 140 is adapted to the curvature of the cover 130, so that the solar panel 140 may be attached to the cover 130. The radian adaptation at this point can be understood as: the curvature of the solar cell panel 140 is the same as that of the cover plate 130.
In the embodiment of the application, the solar panel 140 is a flexible panel, so that the solar panel 140 can be attached to the cover plate 130 and keep consistent with the shape of the cover plate 130. The solar panel 140 is prevented from being harder and having a larger gap with the arc-shaped cover plate 130, which affects the spatial layout inside the ring 100 or results in a thicker ring 100.
In addition, in the embodiment of the present application, the solar panel 140 is a thin film type solar panel, and for example, the solar panel 140 may be made of gallium arsenide, amorphous silicon, copper indium gallium selenium, organic materials, or the like. Compared to the monocrystalline silicon solar panel 140, the thickness of the solar panel 140 is thinner, and the gallium arsenide solar panel 140 is taken as an example, the thickness of the functional area of the gallium arsenide solar panel 140 can be 0.1 μm to 10 μm, and the thickness of the monocrystalline silicon solar panel 140 is generally greater than 150 μm.
In the embodiment of the present application, the thickness of the solar cell panel 140 may be set to 0.1 μm to 300 μm, and the thinner the thickness of the solar cell panel 140 is, the thinner the thickness of the ring 100 may be set. Accordingly, as thin a solar cell panel 140 as possible, for example, a gallium arsenide solar cell panel 140 having a thickness of 0.1 μm to 100 μm may be used.
The solar panel 140 and the cover plate 130 may be connected by gluing, and since the solar panel 140 needs to receive the light transmitted through the cover plate 130, the light transmittance of the glue needs to be considered when the solar panel 140 is glued by the glue. In embodiments of the application, an optical adhesive (Optically CLEAR ADHESIVE, OCA) may be used for bonding. OCA has the advantages of colorless transparency, light transmittance of more than 95%, good cementing strength and the like. The use of OCA to bond the solar panel 140 to the cover 130 ensures that sufficient intensity of light reaches the solar panel 140 after light passes through the cover 130 and the optical cement. In connecting the solar cell panel 140, a bonding process may be used to connect the solar cell panel 140 and the cover plate 130 together through the OCA. The assembled solar panel 140 and cover plate 130 are then mounted together on the housing 110.
In the embodiment of the present application, taking the solar panel 140 as the thin film type gallium arsenide solar panel 140 as an example, the thickness of the solar panel 140 may be set to 85 μm and the thickness of the cover plate 130 may be set to about 500 μm, wherein the gel (OCA) between the solar panel 140 and the cover plate 130 may be set to about 25 μm and the thickness of the shielding layer 133 on the cover plate 130 may be set to about 25 μm. The total thickness of the cover plate 130 and the solar panel 140 after bonding is about 635 μm (0.635 mm), the thickness of the ring 100 can be greatly improved, so that the ring 100 can be designed to be thinner and lighter.
When the solar cell is assembled with the cap plate 130, the assembly process thereof may refer to the following steps: first, the cover plate 130 is glued on the side to which the solar panel 140 is to be connected, i.e. the cover plate 130 is coated with OCA of about 25 μm on the side of the second portion 132 facing away from the first portion 131. Next, the solar panel 140 is bonded to the cover plate 130 by a bonding process, so that the solar panel 140 and the cover plate 130 are bonded together through OCA. Since the size of the solar panel 140 is generally smaller than the size of the second portion 132 of the cover 130, as described above, it is necessary to provide the shielding layer 133 on the annular region of the second portion 132 not covered by the solar panel 140, and the shielding layer 133 is generally formed by printing ink. Accordingly, after the bonding of the solar cell panel 140 to the cap plate 130 is completed, the side of the cap plate 130 to which the solar circuit board 160 is bonded is inked to form the shielding layer 133. The area of the ink is an annular area of the second portion 132 that is not blocked by the solar panel 140, that is, the area surrounded by the ink area is identical to the size of the solar panel 140, wherein the thickness of the ink (the blocking layer 133) is about 25 μm.
Referring back to fig. 3, an energy storage battery 150, a circuit board 160 and an application assembly 170 are also provided in the ring 100, and the above elements are all disposed in the accommodating space, so that in order to ensure that the accommodating space is fully utilized, the thickness of the ring 100 needs to be reduced as much as possible, and the arrangement of the positions of the above elements is required. In an embodiment of the present application, the energy storage cell 150 is disposed between the solar panel 140 and the liner 120. Since both the solar cell panel 140 and the inner liner 120 are arc-shaped, the energy storage cell 150 is also provided in an arc shape in order to utilize space as much as possible. The radian of the side of the energy storage battery 150 near the solar panel 140 is the same as the radian of the solar panel 140, so that the energy storage battery 150 and the solar panel 140 can be attached to each other as much as possible. The arc of the side of the energy storage battery 150 near the liner 120 is set to be the same as the arc of the liner 120, so that the energy storage battery 150 can be attached to the liner 120 as much as possible.
When the circuit board 160 is provided, the circuit board 160 may be connected to one end of the energy storage battery 150, and the circuit board 160 is located between the housing 110 and the energy storage battery 150. This arrangement facilitates electrical connection between the energy storage battery 150 and the circuit board 160. Meanwhile, since the solar panel 140 is connected with the energy storage battery 150, the circuit board 160 is disposed on the energy storage battery 150, the distance between the circuit board 160 and the solar panel 140 can be reduced, thereby facilitating the electrical connection between the solar panel 140 and the circuit board 160.
Since the circuit board 160 may be disposed on the energy storage battery 150, the circuit board 160 and the energy storage battery 150 may be connected through a pin. The circuit board 160 and the solar panel 140 may be connected using Wire bonding (Wire bonding) technology. Bonding may also be referred to as pressure bonding, binding, bonding, wire bonding, and refers to the use of wires (gold wires, aluminum wires, etc.) to connect internal interconnect wiring of solid state circuitry in a microelectronic device using heat and pressure or ultrasonic energy.
As shown in fig. 3, a connection belt is further provided between the circuit board 160 and the solar panel 140, one end of the connection belt is connected to the circuit board 160, and the other end is connected to the solar panel 140. The connection tape and the solar panel 140 may be connected by an adhesive. By providing the connection strap, a fixing effect on the circuit board 160 can be achieved. Specifically, the circuit board 160 and the solar panel 140 may be connected by using a flexible circuit board 160 (Flexible Printed Circuit, FPC 180), and the flexible circuit board 160 may not only realize electrical connection between the circuit board 160 and the solar panel 140, but also realize physical and fixed connection between the circuit board 160 and the solar panel 140.
With continued reference to fig. 3, the application component 170 may provide other free positions in the receiving space, with electrical connection between the application component 170 and the circuit board 160, to power the application component 170. Because the ring 100 is annular, the inner accommodation space is also annular, and when the application assembly 170 and the circuit board 160 are connected, the connection can be performed by using the FPC180, and the FPC180 is flexible, so that the ring can adapt to the annular accommodation space, and is convenient to bend.
In an embodiment of the present application, the application component 170 may be a component with photoplethysmography (photoplethysmographic, PPG) function, abbreviated as PPG component. The PPG assembly includes a light emitting device and a photo detector, which are disposed between the inner liner 120 and the outer shell 110, and a plurality of light holes are formed in the inner liner 120, and the positions of the light holes correspond to those of the light emitting device and the photo detector, so that light emitted by the light emitting device can penetrate the light holes, and the photo detector can receive external light through the light holes.
When the ring 100 is worn on the hand, light from the light emitting device is directed toward the skin, and light reflected back through skin tissue is received by the photodetector and converted into an electrical signal. The absorption of light like muscle, bone, vein, etc. is substantially unchanged (provided that the measurement site does not move significantly), but the absorption of light naturally also changes due to the blood flow in the artery, unlike blood. When converting light into an electrical signal, the absorption of light by the artery is changed, and the absorption of light by other tissues is basically unchanged, so that the obtained signals can be divided into direct current, alternating current, AC, signals and DC signals. The AC signal is extracted to reflect the blood flow characteristic.
Specifically, in an embodiment of the present application, as shown in fig. 3, the light emitting device may include a first light emitting device 171 and a second light emitting device 172, and the photodetector may include a first photodetector 173 and a second photodetector 174. Wherein the first light emitting device 171 and the second light emitting device 172 may be disposed between the first photodetector 173 and the second photodetector 174. This arrangement facilitates the first and second photodetectors 173 and 174 to sufficiently receive the light returned from the human body.
The light emitting devices may be light emitting diodes, and in particular, the first light emitting device 171 may be a light emitting diode that emits green light, and the second light emitting device 172 may be a light emitting diode that emits red light and infrared light. The various components inside the PPG may be electrically connected with each other using the FPC180 so that the various components may be dispersedly disposed in the accommodation space and good connection is achieved.
As shown in fig. 3, one end of the first photo detector 173 is connected to the circuit board 160 through the FPC180, the other end of the first photo detector 173 is connected to one end of the first light emitting device 171 through the FPC180, the other end of the first light emitting device 171 is connected to one end of the second light emitting device 172 through the FPC180, and the other end of the second light emitting device 172 is connected to the second photo detector 174 through the FPC180. The connection includes both electrical and physical connections between adjacent elements. It should be noted that, the above-mentioned FPC180 is a plurality of independent FPCs 180, that is, the plurality of FPCs 180 in the PPG assembly may be mutually independent FPCs 180.
Accordingly, in order to ensure that the light of the light emitting device can reach the human body and that the photodetector can detect the light reflected back from the human body, a plurality of light holes are provided on the inner liner 120. Specifically, in the embodiment of the present application, four light holes are disposed on the inner liner 120, and the positions of the four light holes correspond to the first light emitting device 171, the second light emitting device 172, the first photodetector 173 and the second photodetector 174, respectively. The light holes of the inner liner 120 corresponding to the first light emitting device 171 and the second light emitting device 172 facilitate the light emitted from the first light emitting device 171 and the second light emitting device 172 to be irradiated to the human body. The light holes of the inner liner 120 corresponding to the first and second photodetectors 173 and 174 facilitate the first and second photodetectors 173 and 174 to detect the light returned from the human body.
Since the photodetector mainly receives light returned from the human body side, the more the light returned from the human body side is included in the light received by the photodetector, the higher the accuracy of the test. To achieve this, a protrusion is provided on the side of the inner liner 120 remote from the outer shell 110, the position of the protrusion corresponding to the position of the photodetector. In the embodiment of the present application, the ring 100 is provided with the first photoelectric detector 173 and the second photoelectric detector 174, so two protrusions are provided on the side of the inner liner 120 away from the outer shell 110, and the positions of the two protrusions correspond to the positions of the first photoelectric detector 173 and the second photoelectric detector 174, respectively.
When the ring 100 is worn on the hand, the two protrusions contact the finger, so that the inner liner 120 and the skin can be tightly adhered, and external ambient light is isolated from entering the first and second photodetectors 173 and 174, so that the light received by the first and second photodetectors 173 and 174 is basically returned from the human body side, thereby improving the detection accuracy of the PPG.
In the embodiment of the present application, reference may be made to fig. 9 for a schematic diagram of a charging circuit structure of a ring 100, and fig. 9 is a schematic diagram of a charging circuit structure of a ring 100 according to the embodiment of the present application. As shown in fig. 9, the solar panel 140 is electrically connected to the circuit board 160, and a solar Charger (Charger) and a linear Charger (LINAER CHARGER) are disposed in the circuit board 160, where the solar Charger can regulate the voltage of the electric energy converted by the solar panel 140, so as to supply power to the energy storage battery 150 or supply power to the application component 170 (load), and the linear Charger can charge the energy storage battery 150 by controlling the voltage and current changes. As the circuit board 160 is electrically connected to the application component 170 and the energy storage battery 150, specifically, as shown in fig. 9, one end of the solar charger in the circuit board 160 is electrically connected to the solar panel 140, the other end is electrically connected to the application component 170 and the linear charger, and the linear charger is electrically connected to the energy storage battery 150. The electric energy converted by the solar panel 140 is processed by a solar charger and then is used as a system power supply for voltage output. The power output by the solar charger may directly power the application components 170 in the ring 100 or may charge the energy storage battery 150 via a linear charger. The linear charging includes two triodes (Q1 and Q2), the collector of the first triode (Q1) can be connected with an AC input (ac_in) power supply, the emitter of the first triode (Q1) is connected with the collector of the second triode (Q2), and the emitter of the first triode (Q1) and the second triode (Q2) can be connected with a pin on the circuit board 160, and the pin is electrically connected with the output end of the solar charger and the application component 170. An emitter of the second transistor (Q2) is electrically connected to the energy storage battery 150.
The solar panel 140 collects external light to convert light energy into electric energy, and the solar charger adjusts the voltage of the solar panel 140 to a proper voltage, so that the application component 170 can be directly powered, or the energy storage battery 150 can be charged through a second triode (Q2) in the linear charger. Since the application assembly 170 is connected to the second transistor (Q2) in the linear charger, the energy storage battery 150 may also supply power to the application assembly 170 through the second transistor (Q2) in the linear charger.
In a specific example, taking gallium arsenide solar panel 140 as an example, the battery area of solar panel 140 as an example of 120mm 2, the loss and charging energy of the solar modules (solar panel 140 and solar charger) and the charging links in ring 100 can be referred to in table 1.
TABLE 1
It should be noted that, since the ring 100 in the embodiment of the present application can convert light energy into electric circuit, when receiving light energy, the light energy has a certain energy, and when the ring 100 itself works, heat is generated, which may cause the ring 100 to be hotter. Therefore, a certain heat dissipation is required for the ring 100.
For example, when the ring 100 is charged under outdoor sunlight, the ring 100 may detect the illumination intensity of the outdoor light, and when the solar charger detects that the illumination intensity is higher than a preset threshold, the ring 100 may enter a preset power saving mode, thereby reducing self-heating.
In addition, the ring 100 may be physically cooled. Specifically, the FPC180 board in the ring 100 may be in contact with the inner wall of the outer case 110 of the ring 100, and graphene may be disposed between the FPC180 and the outer case 110. Fig. 10 may be referred to in the heat dissipation direction, and fig. 10 is a schematic view of the heat dissipation direction of the ring 100 according to the embodiment of the present application. As shown in fig. 10, when the FPC180 is provided, the FPC180 and the housing 110 may be attached together, and graphene may be provided between the FPC180 and the housing 110. The heat of the solar panel 140 caused by the optical fiber irradiation can be transferred to the FPC180 board, then transferred to the metal housing 110 through the graphene, and then transferred to the outside or the heat dissipation fitting of the ring 100 charging box 200 through the metal housing 110.
The above embodiment introduces the main structure and working principle of the ring 100, when the ring 100 is worn on the hand, the ring 100 can utilize the internal structure of the ring 100 to realize the conversion from light energy to electric energy, thereby improving the endurance of the ring 100 and improving the use experience of users. The charging box 200 may also be used to charge the ring 100 when the ring 100 is low or depleted. A charging cartridge 200 according to an embodiment of the present application will be described.
In one embodiment of the present application, a charging box 200 for charging the ring 100 is also provided. Referring to fig. 11 and 12, fig. 11 is a schematic external view of a charging box 200 according to an embodiment of the present application, and fig. 12 is a schematic internal structure of the charging box 200 according to an embodiment of the present application. Wherein the ring 100 is placed in each of the charging boxes 200 shown in fig. 11 and 12.
As shown in fig. 11 and 12, the charging cartridge 200 includes a base 210 and a cover 220, one side of the cover 220 being rotatably coupled to the base 210 such that the cover 220 can rotate around the base 210, thereby achieving opening and closing of the charging cartridge 200. Fig. 11 is an external view of the case cover 220 when it is opened, and fig. 12 is a structural view of the case cover 220 when it is closed. Therein, a light source 230, a control chip 240 and a control switch 250 are also provided inside the charging cartridge 200. The light source 230 is disposed inside the cap 220, and the light source 230 is electrically connected to the control chip 240. The light source 230 may include a full spectrum light emitting diode 231 and an infrared lamp 232.
The control switch 250 is disposed on the cover 220 or the base 210, the control switch 250 detects the opening and closing change between the cover 220 and the base 210, generates a detection signal, and the control switch 250 is electrically connected to the control chip 240. The control chip 240 is disposed on the cover 220 or the base 210, and the control chip 240 controls the operating state of the light source 230 according to the detection signal. And a charging interface 270 is provided on the base 210, the control chip 240 is electrically connected with the charging interface 270, and the charging interface 270 is used for supplying power to the light source 230 and the electronic components in the charging and the charging.
In the embodiment of the present application, the working principle of the charging box 200 may refer to fig. 13, and fig. 13 is a schematic diagram of the working principle of the charging box 200 according to the embodiment of the present application. As shown in fig. 13, the charging interface 270 and the control switch 250 are electrically connected to the control chip 240, and the control chip 240 is electrically connected to the light source 230 (the full spectrum light emitting diode 231 and the infrared lamp 232), respectively. The charging interface 270 may be a USB interface, and the 5V power supply may be connected to the input end of the control chip 240 through the USB interface, and the control chip 240 boosts the voltage and supplies power to the infrared lamp 232 and the full spectrum led 231 with constant current, so that the light source 230 emits light stably, and transmits energy to the solar panel 140 of the ring 100 in the form of light energy. The control switch 250 detects a changed state of the charging cartridge 200 when it is opened and closed, and outputs a control signal enabling the control chip 240 to turn on or off the light source 230.
When the control switch 250 detects that the charging box 200 is in the closed state, a first detection value is generated at this time and sent to the control chip 240, and the control chip 240 can control the light source 230 to be in the working state according to the first detection value so as to charge the ring 100 in the charging box 200. When the control switch 250 detects that the charging cartridge 200 is in the open state, a second detection value is generated at this time, and the second detection value is sent to the control chip 240, and the control chip 240 may control the light source 230 to be in the non-operating state according to the second detection value, so that the charging cartridge 200 is temporarily in the non-charging state.
In addition, a status check of whether the ring 100 is in place may be incorporated into the charging box 200. When the ring 100 is in the in-place state and the detection value of the control switch 250 is the first detection value, the control chip 240 is enabled to control the light source 230 to be in the working state, so as to charge the ring 100 in the charging box 200. The detection of whether the ring 100 is in place is increased, so that the light source 230 is still in a working state when the charging box 200 is in a closed state and the ring 100 is not positioned in the charging box 200, and resource waste is avoided.
In one embodiment of the present application, the control switch 250 includes a hall sensor 251 and a magnet 252, wherein the hall sensor 251 may be disposed on the cover 220 and the magnet 252 is disposed on the base 210. When the cover 220 is fastened to the base 210, the position of the hall sensor 251 corresponds to the position of the magnet 252. When the cover 220 is in the closed state or the open state, the magnitude of the magnetic field detected by the hall sensor 251 is different, and thus, the first detection value and the second detection value may be generated according to the magnetic field variation value detected thereby to control the operation state of the light source 230. Of course, the hall sensor 251 may be disposed on the base 210, and the magnet 252 may be disposed on the cover 220, and the same principle of operation is adopted. In addition, other types of detection devices may be used as the control switch 250, and embodiments of the present application are not limited to a specific type of control switch 250.
The charging box 200 provided in the embodiment of the present application has the principle that the light source 230 is disposed in the charging box 200, and the ring 100 is charged in the form of light energy, which is consistent with the principle that the ring 100 is charged by using external light when the ring 100 is worn on the hand. That is, the solar cell panel 140 on the ring 100 receives the light generated from the light source 230 in the charging box 200, and then performs photoelectric conversion to charge the energy storage battery 150 in the ring 100.
When the ring 100 is charged in the charging box 200, in order to facilitate the fixing of the ring 100, the ring 100 can stably receive the light generated by the light source 230, the fixing post 260 is provided on the base 210, the fixing post 260 is used for fixing the ring 100, and the size of the fixing post 260 is matched with the size of the inner space of the ring 100.

And the solar panel 140 is oriented to the direction of the light source 230, so that the position of the light source 230 corresponds to the position of the solar panel 140, and the solar panel 140 can better receive light, thereby improving the charging efficiency. Then, when the cover 220 is fastened to the base 210, the charging box 200 is closed, so that the ring 100 can be charged.
In an embodiment of the present application, in order to make the light emitted from the light source 230 more similar to the solar rays, the light source 230 includes one or more full spectrum light emitting diodes 231 and one or more infrared lamps 232 when the light source 230 is disposed. By setting the infrared lamp 232 as the light source 230, the solar panel 140 can receive the full spectrum light from visible light to infrared light, and the infrared light emitted by the infrared lamp 232 can be used as the supplement of silicon visible light and carries higher energy, thereby improving the charging efficiency. By setting the full-spectrum light emitting diode 231 as the light source 230, the full-spectrum light emitting diode 231 can complement partial spectrums of short-wave purple light, green light, short-wave green light and long-wave red light which are lack by the light source 230, so that spectral continuity and integrity are greatly enhanced, the color gamut is wide, and the full-spectrum light emitting diode is more approximate to the full spectrum of sunlight. Not only can the intelligent ring 100 be charged, but also the eyes can be protected.
In setting the number of light emitting diodes in the light source 230, one full spectrum light emitting diode 231 and one infrared lamp 232 may be provided as the light source 230. Taking the solar panel 140 in the ring 100 as the gallium arsenide solar panel 140, and taking the example that the battery area of the solar panel 140 can reach 120mm 2, the maximum output power consumption of the solar battery is 36.2mW, and the requirement of light charging can be met by only needing one full spectrum LED of 500mW and one infrared lamp 232 respectively according to the 25% luminous rate. Wherein the relevant parameters may be referred to in table 2.
TABLE 2
As can be seen from table 2, the above requirements are satisfied when the electric power of the light emitting diode satisfies 456.31mW, and thus the above light charging requirements are satisfied by using 500mW of full spectrum LED and one infrared lamp 232.
In the embodiment of the present application, taking the solar panel 140 in the ring 100 as the gallium arsenide solar panel 140, and the battery area of the solar panel 140 may reach 120mm 2 as an example, the energy storage battery 150 is a lithium battery as an example, and the benefits of charging by using solar energy may be referred to in table 3.
TABLE 3 Table 3
In the process of charging the ring 100 using the charging box 200, the light source 230 in the charging box 200 is always in an operating state, which may cause the temperature in the charging box 200 to be too high, so as to affect the charging of the energy storage battery 150 in the ring 100. Taking the example of the energy storage battery 150 in the ring 100 as a lithium battery, the charging temperature of the lithium battery is typically 0 ° to 45 °. Therefore, a temperature detection sensor is generally further provided in the ring 100, so that the temperature of the energy storage battery 150 can be detected.
Fig. 14 may be referred to in the charging process of the energy storage battery 150 in the ring 100, and fig. 14 is a schematic diagram of a charging process of the ring 100 according to an embodiment of the present application. As shown in fig. 14, when the temperature TBAT of the lithium battery is detected to be less than 0 ° or greater than 45 °, the linear charger on the circuit board 160 within the ring 100 stops charging the lithium battery. The lithium battery may be charged when the temperature TBAT of the lithium battery is between 0 ° and 45 °. The charging process is divided into a constant current charging stage and a constant voltage charging stage. When the electric quantity of the lithium battery is low, the lithium battery is charged in a constant-current charging mode, for example, the lithium battery is charged with a constant current of about 782.17mA, and when the voltage of the lithium battery reaches a certain threshold value, for example, 4.48V, the lithium battery is continuously charged in a constant-voltage charging mode, for example, the lithium battery is charged with a constant voltage of 100mV until the charging of the lithium battery is completed.
