Detailed Description

In order to make the technical solution and the clarity of the embodiments of the present application, the terms involved in the embodiments of the present application are explained first.

Surface mount technology (Surface Mounted Technology, SMT) which mounts leadless or short-lead surface mount components on the surface of a circuit board or other substrate, and circuit attach technology which performs solder assembly by reflow or dip soldering.

Reflow soldering refers to the use of solder paste (a mixture of solder and flux) to attach one or more electronic components to contact pads, and then the solder is melted by controlled heating to achieve a permanent bond, which may be soldered using a reflow oven, infrared heat lamp, or heat gun, among other means.

In addition, in the present application, the terms "first," "second," "third," etc. (if any) are used to distinguish similar objects from each other and are not necessarily used to describe a particular order or sequence. It is to be understood that the data so used may be interchanged where appropriate such that the embodiments of the application described herein may be capable of being practiced otherwise than as specifically illustrated and described.

Electronic devices such as mobile phones and wearable devices are increasingly used. Among them, electronic devices tend to be multifunctional, dense and miniaturized, and higher demands are put on standby time of the electronic devices. Such as increasing the battery capacity of the electronic device and decreasing the number of charges of the battery.

The wearable device, such as a wristwatch, may be configured to increase the thickness of the dial structure of the wristwatch to accommodate the battery. In this way, a thicker battery can be placed within the dial structure to increase the capacity of the battery by increasing the thickness of the battery. However, the watch is thicker due to the mode, so that the watch is heavy and inconvenient to wear, and is not beneficial to miniaturization development.

Limited by the actual volume of the wearable device (e.g., the volume of the dial structure) and the volume of the battery compartment, the battery compartment inside the dial structure has difficulty in giving more positions, and the volume of the battery cannot continue to expand.

Based on the above, the embodiment of the application provides an electronic device and a light condensing device, wherein the electronic device comprises a body and a solar cell unit, the solar cell unit comprises a substrate and a plurality of solar cell modules, and the solar cell modules are used for converting light energy into electric energy and transmitting the electric energy to the body through the substrate so as to supply power for various electronic components in the electronic device. According to the application, the solar energy is converted into electric energy through each solar battery module of the solar battery unit, so that electric energy is supplemented for the electronic equipment, and the cruising ability of the electronic equipment is improved.

The electronic device provided by the embodiment of the application can include, but is not limited to, a fixed terminal or a mobile terminal such as a mobile phone, a tablet computer, a notebook computer, an ultra-mobile personal computer (ultra-mobile personal computer, UMPC), a handheld computer, a touch television, an interphone, a netbook, a POS (point of sale) machine, a personal digital assistant (personal digital assistant, PDA), a wearable device, a virtual reality device, and the like. The wearable device may include, but is not limited to, a wristwatch, a wristband, a pair of smart shoes, a pair of smart socks, glasses, a helmet, a headband, and the like. The wrist-watch can be intelligent wrist-watch, and the bracelet can be intelligent bracelet. For convenience of description, the electronic device is used as a watch (for example, a smart watch) in the embodiment of the application.

The electronic device of the present application will be described with reference to the drawings and examples.

Fig. 1 shows an expanded state of the wristwatch, fig. 2 is a structural view of fig. 1 in a top view, and fig. 3 shows a partially enlarged state at a in fig. 1. Referring to fig. 1 to 3, an electronic device provided by an embodiment of the present application includes a body 100 and a solar cell 200, the solar cell 200 includes a substrate 210 and a plurality of solar cell modules 220, the substrate 210 is electrically connected to the body 100, and each solar cell module 220 is disposed on a surface of the substrate 210 facing away from the body 100. Each solar cell module 220 is electrically connected to the substrate 210, and the solar cell module 220 is configured to collect light energy to convert the light energy into electrical energy, and supply power to the body 100 through the substrate 210.

Fig. 4 and 5 show the unfolded state of the wristwatch in two different configurations, respectively. In the present application, the body 100 may be a wristwatch body, and the body 100 may include a supporting member and various electronic components (e.g., a battery, an indicator light, a first circuit board, etc.). The support member may be used to support the solar cell 200, and the solar cell 200 is used to supply power to various electronic components. Illustratively, the support members may include a dial structure 110 and a band structure 120 of the wristwatch. The number of solar cells 200 may be one or more, and the solar cells 200 may be disposed on at least one of the dial structure 110 and the band structure 120. For example, as shown in fig. 4, the solar cell unit 200 may be disposed on the dial structure 110; alternatively, as shown in fig. 1, the solar cell unit 200 may be disposed on the wristband structure 120; alternatively, as shown in fig. 5, both the dial structure 110 and the band structure 120 are provided with solar cells 200. In this way, the position setting of the solar cell unit 200 is flexible, and the setting position of the solar cell unit 200 can be selected according to different types of watches.

For example, a wide variety of watches with a wristband structure 120 may alternatively be provided with the solar cell unit 200 on the wristband structure 120. The dial structure 110 is a larger type of wristwatch, and the solar battery unit 200 may be selectively disposed on the dial structure 110.

Fig. 6 shows the structure of the first solar cell unit. Referring to fig. 1 and 6, the substrate 210 may be a first circuit board, and the substrate 210 is a second circuit board with high reliability, light weight, and thin thickness. Embodiments of the present application and the accompanying drawings are described with reference to substrate 210 as a double-layer circuit board. Specifically, the substrate 210 may include a first green oil layer 211, a first copper layer 212, a dielectric layer 213, a second copper layer 214, and a second green oil layer 215 stacked in this order, and the dielectric layer 213 includes a plurality of vias 2131 therein, and the first copper layer 212 and the second copper layer 214 are connected through the vias 2131. The substrate 210 may be prepared by a masking process (also referred to as a stretching process) to pattern the first copper layer 212 and the second copper layer 214. The substrate 210 prepared by the stretching process has the advantages of lower cost, smoother surface and better light reflection.

To facilitate connection of the solar cell module 220 with various electronic components in the electronic device through the substrate 210, power is supplied to the various electronic components. In a specific implementation, the substrate 210 has at least two electrical connection portions 216, and the electrical connection portions 216 are used for electrically connecting with the main body 100. The electronic components such as the battery and the indicator light may be electrically connected to the first circuit board, and the electrical connection portion 216 may be electrically connected to the first circuit board, so that power is supplied to the other electronic components through the first circuit board. Or, the battery on the first circuit board is charged while the rest of the electronic components are powered through the first circuit board.

In particular implementations, electrical connection 216 may be a flexible circuit board (e.g., FPC), wire, silver paste, or flexible electrical connection material, among others. The electrical connection portion 216 may be used as an extraction electrode, and at least one of the dial structure 110 and the watchband structure 120 may have an electrical connection portion, where the extraction electrode may extend to a position of the electrical connection portion and be electrically connected to the electrical connection portion by a magnetic attraction or a fastening connection manner, so that the solar battery module 220 is electrically connected to the body 100.

In the present embodiment, the substrate 210 is used for supporting each solar cell module 220, and in addition, the substrate 210 has a conductive function, each solar cell module 220 converts absorbed light energy into electric energy, so that the electric energy is transmitted to various electronic components of the electronic device through the substrate 210, and thus, the various electronic components in the electronic device are powered through each solar cell module 220. The light energy absorbed by the solar cell module 220 may be light energy generated by ambient light such as sunlight or lamplight.

In a specific implementation, the solar battery module 220 and the battery in the electronic device jointly supply power for various electronic components in the electronic device; or, the battery in the electronic device is charged through the solar battery module 220, and various electronic components in the electronic device are powered through the battery; alternatively, various electronic components other than the battery in the electronic device are powered by the solar battery module 220, that is, the battery is not provided in the electronic device, and various electronic components in the electronic device are powered directly by the solar battery module 220.

The electronic device provided by the embodiment of the application comprises a body 100 and a solar cell 200, wherein the solar cell 200 comprises a substrate 210 and a plurality of solar cell modules 220, and the solar cell modules 220 are used for converting light energy into electric energy and transmitting the electric energy to the body 100 through the substrate 210 so as to supply power for various electronic components in the electronic device. According to the application, the solar battery modules 220 of the solar battery unit 200 convert light energy into electric energy, so that electric energy is supplemented for the electronic equipment, the cruising ability of the electronic equipment is improved, and the user experience is improved.

In the present application, the connection manner of each solar cell module 220 and the substrate 210 is not limited, and each solar cell module 220 may be mounted on the substrate 210 by way of example. Specifically, each solar cell module 220 is sequentially placed on the substrate 210, and is mounted on the substrate 210 by SMT (e.g., surface mount technology). Wherein each solar cell module 220 may be fixed to the substrate 210 using reflow soldering. Thus, the solar cell modules 220 are firmly connected to the substrate 210, and the connection strength between each solar cell module 220 and the substrate 210 is high. In this way, the solar cell module 220 can be prevented from falling off the substrate 210 due to the solar cell 200 being jolted or bumped during transportation, handling or installation of the solar cell 200. In addition, each solar cell module 220 is fixed on the substrate 210 by adopting a mounting mode, so that the mounting is convenient and the cost is saved. The solar cell module 220 is electrically connected to the first copper layer 212 or the second copper layer 214.

When the solar cell modules 220 are mounted on the substrate 210, the respective solar cell modules 220 are disposed on the substrate 210 at uniform intervals. In this way, the arrangement of the solar cell modules 220 is regular, so that the solar cell modules 220 can be automatically attached.

It is understood that the solar cell modules 220 disposed on the substrate 210 may be connected in parallel or in series. In particular, the number of solar cell modules 220 and the electrical connection between each solar cell module 220 are selected according to design requirements.

It should be noted that the shape of the solar cell module 220 is not limited in the present application, and the solar cell module 220 may be cylindrical or rectangular.

It is understood that in the embodiment of the present application, the solar cell 200 may be disposed on the protective case of the mobile phone. In order to facilitate the solar cell 200 to absorb light energy, the cell phone is prevented from shielding the solar cell 200. In the present application, the solar cell unit 200 is disposed on the outer surface of the protective case, that is, the surface of the protective case facing away from the mobile phone. The specific position of the solar cell 200 is not limited in this embodiment, as long as the position of the rear camera of the mobile phone is avoided.

In the present application, the solar cell module 220 is not limited, and the solar cell module 220 may be a solar cell such as gallium arsenide, amorphous silicon, or perovskite. Embodiments of the present application and the accompanying drawings are described with respect to solar cell module 220 as a gallium arsenide solar cell.

Specifically, the gallium arsenide solar cell may also include a gallium arsenide layer 221 and an antireflection film layer 222 that are stacked. Wherein the anti-reflection film layer 222 is used for reducing reflection of light, and the gallium arsenide layer 221 faces the substrate 210. The gallium arsenide layer 221 faces away from the two electrodes provided on the surface of the anti-reflection film layer 222, and both electrodes of the gallium arsenide layer 221 face toward the substrate 210 and are electrically connected with the substrate 210. In the present application, light enters the gallium arsenide layer 221 through the anti-reflection film layer 222, and compared with the arrangement of the gallium arsenide layer 221 and the anti-reflection film layer 222 between two electrodes, light enters the gallium arsenide layer 221 through one of the two electrodes and the anti-reflection film layer 222 in sequence, so that the absorption of the gallium arsenide layer 221 by the light is prevented from being influenced by the electrodes on the anti-reflection film layer 222, and the conversion efficiency of the gallium arsenide layer 221 can be improved.

The gallium arsenide solar cell has good temperature resistance, and compared with a silicon photocell, the gallium arsenide solar cell has wider forbidden band than silicon, so that the spectral response and the spatial solar spectrum matching capability of the gallium arsenide solar cell are better than those of silicon. Thus, the photovoltaic conversion rate of gallium arsenide solar cells is high relative to silicon photovoltaic cells.

The specific positions of the solar cell units 200 are described below.

Fig. 7 shows a state when the wristwatch is worn. Referring to fig. 7, in the present application, wristband structure 120 has opposing inner and outer surfaces 121 and 122, the inner surface 121 being for contact with a wearer's wear (e.g., a wrist) and solar cell unit 200 being located on the outer surface 122. When the electronic device is worn, the solar cell 200 and the dial structure 110 are located on the same side of the wearing part.

When the solar cell unit 200 is disposed on the inner surface 121, the solar cell unit 200 is shielded between the band structure 120 and the wrist of the wearer, so that light is difficult to enter between the band structure 120 and the wrist of the wearer, resulting in less light energy absorbed by the solar cell unit 200. Accordingly, the present application provides for the solar cell unit 200 to be disposed on the outer surface 122 of the wristband structure 120. In this way, the solar cell 200 may be exposed when the wristwatch is worn, thereby facilitating absorption of light energy by the solar cell 200.

Since the wristwatch is frequently switched between being worn and not being worn (e.g., being detached from the wrist), if the solar cell 200 is bent in a large arc, frequent bending of the solar cell 200 may affect the connection stability between the solar cell 200 and the band structure 120, and the solar cell 200 may be detached from the band structure 120. Thus, in the present application, the solar cell unit 200 and the dial structure 110 are located on the same side of the wrist of the wearer when the wristwatch is worn. That is, the solar cell 200 is disposed near the dial structure 110. In this way, the curvature of the solar cell 200 being bent is smaller, reducing the problem of the solar cell 200 falling off the wristband structure 120.

The band structure 120 includes a first band 123 and a second band 124, the first band 123 and the second band 124 are respectively connected to both sides of the dial structure 110, and the first band 123 and the second band 124 are detachably connected. Wherein, the first watchband 123 and the second watchband 124 can be both connected with the dial structure 110 in a rotating way through a rotating shaft. The first wristband 123 and the second wristband 124 may be connected by a velcro; or the first band 123 and the second band 124 may be connected by a clasp.

Fig. 8 and 9 show the unfolded state of the wristwatch of the other two different structures, respectively. At least one of the first band 123 and the second band 124 is provided with the solar cell unit 200. Specifically, as shown in fig. 7, the solar cell unit 200 may be provided only on the first band 123; alternatively, as shown in fig. 8, the solar cell unit 200 may be provided only on the second wristband 124; alternatively, as shown in fig. 9, the solar cell 200 is provided on each of the first band 123 and the second band 124. Compared to the embodiment of fig. 7 or 8, in which the solar cell 200 is provided on one of the first band 123 and the second band 124, the solar cell 200 is provided on both the first band 123 and the second band 124 in the embodiment of fig. 9, and the number of solar cells 200 is increased, thereby making the cruising ability of the wristwatch higher.

Fig. 10 shows the structure of the section B-B in fig. 5. Referring to fig. 10, in some embodiments, the solar cell unit 200 may also be disposed on the dial structure 110. The dial structure 110 includes a support ring 111 and a support disc 112, the support disc 112 is located in the support ring 111, the support disc 112 has a display portion 1121 for indicating time, and the solar cell 200 is wound around a circumference of the support disc 112, where the solar cell 200 is located between the support ring 111 and the support disc 112. In this way, the solar cell 200 is prevented from blocking the display portion 1121 on the support plate 112.

The display portion 1121 may be a display screen for displaying time, or the display portion 1121 may be provided with pointers and time numerals (for example, arabic numerals 1 to 12, or roman numerals i to 12) by which time is indicated. Further, a member for displaying date, temperature, and the like may be provided on the support plate 112. The date may be a month of the year, or the date may be a month of the year.

In a specific implementation, the solar cell 200 is in contact with an inner sidewall (e.g., sidewall 1111) of the support ring 111. In other words, the solar cell unit 200 may extend to the sidewall 1111, thereby increasing the area of the solar cell unit 200 and improving the space utilization between the support ring 111 and the support tray 112.

It is understood that the solar cell 200 may also abut against the outer sidewall of the support tray 112.

Fig. 11 and 12 show the developed states of the wristwatch of the other two structures, respectively, and fig. 13 shows the structure of the solar cell unit in fig. 12. On the basis of the above-described embodiment of fig. 10, in another embodiment, the solar cell units 200 are also provided on the support tray 112. In other words, the solar cell unit 200 is also integrated on the support tray 112. In this way, the area of the solar cell 200 is increased, thereby enabling the solar cell 200 to provide more power to the wristwatch.

In a specific implementation, in one possible implementation, the solar cell unit 200 may cover the entire support tray 112, and the solar cell unit 200 on the support tray 112 may be a semi-transparent structural solar cell. Thereby, the solar cell 200 is prevented from blocking the display screen. As shown in fig. 11 to 13, in another possible implementation, the substrate 210 may be a transparent electrode, and each solar cell module 220 is a grid bar disposed on the transparent electrode at intervals, so that when the display portion 1121 is a display screen, information displayed on the display screen may be transmitted through a gap between adjacent solar cell modules 220 to be recognized by the wearer.

In this embodiment, the width (e.g., the length in the X direction in fig. 13) of the grid-shaped solar cell module 220 is not limited, so long as the information that the solar cell module 220 affects the display screen display is avoided or reduced, that is, the shielding of the information displayed by the display screen by the solar cell module 220 is avoided or reduced.

As shown in fig. 11 and 12, each solar cell module 220 may be arranged on the support tray 112 in a regular form such as an array form. In some embodiments, the solar cell modules 220 may also be arranged in an irregular pattern on the support tray 112.

Fig. 14 shows the structure of a second solar cell unit. Referring to fig. 14, in some embodiments, the solar cell unit 200 further includes a light-transmitting encapsulation layer 230, each solar cell module 220 is encapsulated on the substrate 210 by the light-transmitting encapsulation layer 230, and the solar cell modules 220 are located in the light-transmitting encapsulation layer 230. In this way, the solar cell module 220 can be protected by the light-transmitting encapsulation layer 230 on the basis of not affecting the solar cell module 220 to receive light energy, so as to prevent the solar cell module 220 from being corroded by impurities in the air, thereby causing the electrical performance to be reduced. The life of the solar cell module 220 is improved, and the solar cell unit 200 is provided with sufficient mechanical strength to withstand impacts, vibrations, or other external forces occurring during transportation, installation, and use.

In some embodiments, the light transmissive encapsulant layer 230 is a transparent epoxy layer, an EVA plastic layer, or a POE plastic layer. In one embodiment, each solar cell module 220 may be encapsulated with a transparent epoxy. The transparent epoxy resin can be cured at low temperature or normal temperature, and the curing speed is high; the cured adhesive has high adhesive strength, good adhesive hardness, certain toughness, good dampproof, waterproof, oil-proof and dustproof performances, good insulation, compression resistance, adhesive strength and the like. In another embodiment, each solar cell module 220 may be encapsulated with EVA plastic. EVA is formed by copolymerizing ethylene and acetic acid. Ethylene-vinyl acetate copolymer (Ethylene Vinyl Acetate Copolymer), EVA for short. EVA with 20-28% vinyl acetate content is used in hot melt adhesive. EVA has better toughness, impact resistance, filler compatibility and heat sealing performance. The POE (Polyolefin elastomer) plastic is a thermoplastic elastomer which adopts ethylene and octene of a metallocene catalyst to realize in-situ polymerization, and the POE plastic has good toughness, processability and aging resistance.

Fig. 15 shows a structure of a third solar cell unit. Referring to fig. 10 and 15, in some embodiments, the solar cell unit 200 further includes a light-transmitting protective layer 240, where the light-transmitting protective layer 240 covers a surface of the light-transmitting encapsulation layer 230 facing away from the substrate 210. The light-transmitting protective layer 240 is at least one of a glass ceramic layer and tempered glass. The hardness of the light-transmitting protective layer 240 is greater than that of the light-transmitting encapsulation layer 230, and the light-transmitting encapsulation layer 230 is protected by the light-transmitting protective layer 240.

In a specific implementation, the light-transmitting protective layer 240 and the light-transmitting encapsulation layer 230 are bonded by OCA optical cement or rubber adhesive. In this way, while the light-transmitting protective layer 240 and the light-transmitting packaging layer 230 are firmly connected, light can enter the solar cell module 220 normally, and the solar cell module 220 is not affected to absorb light energy. Wherein, OCA (Optically Clear Adhesive) optical cement is used for cementing the special adhesive of the transparent optical element. The OCA optical adhesive is colorless and transparent, has light transmittance of more than 95% and good cementing strength.

In an embodiment, the surface of the solar cell module 220 facing away from the substrate 210 may be modified by electroplating, electrophoresis, laser etching, etc., so as to improve the overall aesthetic appearance of the solar cell 200.

In the above embodiment, the light-transmitting encapsulation layer 230 and the light-transmitting protection layer 240 are sequentially disposed on the solar cell module 220. In some embodiments, the light-transmitting protective layer 240 is disposed directly on the solar cell module 220 to protect the solar cell module 220. That is, in the embodiment, the light-transmitting encapsulation layer 230 is not disposed, and compared with the embodiment of fig. 14, the thickness of the entire solar cell unit 200 can be reduced by disposing the light-transmitting encapsulation layer 230 between the solar cell module 220 and the light-transmitting protection layer 240. In this way, the impact of the solar cell 200 on the thickness of the wristwatch can be reduced.

The structure and the position of the solar cell 200 are described above, and the following description is made on the mounting method of the solar cell 200.

Fig. 16 shows a cross-sectional view of a first of the C-C sections of fig. 7. Referring to fig. 7 and 16, the body 100 is provided with a mounting groove 130, and the solar cell unit 200 is at least partially positioned in the mounting groove 130.

In a specific implementation, the mounting groove 130 may be formed on the watchband structure 120 in fig. 7, and by placing at least a portion of the solar cell unit 200 in the mounting groove 130, a mounting space may be provided for the solar cell unit 200 by the mounting groove 130, and a thickness of the solar cell unit 200 occupied by the body 100 may be reduced (e.g., a thickness of the solar cell unit 200 occupied by the body 100 in the Y direction in fig. 16 is avoided). The mounting groove 130 may also be formed by the support ring 111 and the support plate 112 in fig. 10.

In order to firmly bond the solar cell 200 and the mounting groove 130, at least one surface in the mounting groove 130 is a rough surface in the present application. Illustratively, the mounting groove 130 may be rectangular parallelepiped in shape, the mounting groove 130 having four inner sides 131 and a groove bottom 132. The four inner side surfaces 131 are wound around the circumference of the groove bottom surface 132, and at least one of the groove bottom surface 132 and the four inner side surfaces 131 is roughened, whereby the solar cell 200 can be firmly bonded in the mounting groove 130. The four inner sides 131 and the groove bottom 132 may be roughened, so that the solar cell 200 is more firmly bonded in the mounting groove 130.

In particular implementations, the grooves 130 may be mounted by knife rubbing or solution etching (e.g., allyltriethoxysilane solution) to form roughened surfaces on the inner side 131 and/or groove bottom 132.

In the present application, the solar cell 200 is bonded to the mounting groove 130. That is, the solar cell module 220, the light-transmitting protective layer 240, and the sides of the light-transmitting encapsulation layer 230 opposite to the mounting grooves 130 are bonded to the mounting grooves 130. The solar cell 200 is fixed to the mounting groove 130 by means of adhesion, and thus, compared with other connection modes such as screw connection and clamping connection, no special connection portion is required, so that space is saved, and accordingly, the space can be saved for increasing the size of the solar cell module 220.

In the present application, the mounting groove 130 may be integrally formed with the body 100. Thus, the processing is more convenient and the time is saved. In particular implementations, the body 100 having the mounting groove 130 may be prepared by injection molding or flat plate compression molding. The material of the watchband structure 120 includes, but is not limited to, fluororubber, leather, or titanium alloy.

Fig. 17 shows a cross-sectional view of a second of the C-C sections of fig. 7. Referring to fig. 17, the solar cell unit 200 and the mounting groove 130 may be bonded by a first adhesive layer 250. The first adhesive layer 250 may be an RTV silicone layer, a fluororubber adhesive layer, or a thermosetting adhesive layer. In a specific implementation, the solar cell unit 200 and the mounting groove 130 may be bonded by using RTV silicone rubber, where the RTV silicone rubber (room temperature vulcanized silicone rubber) is room temperature vulcanized silicone rubber, and the RTV silicone rubber has good adhesion, sealing, insulation, moisture resistance and vibration resistance. The solar cell 200 and the mounting groove 130 may be fixed by using a fluororubber adhesive or a thermosetting adhesive, so long as the solar cell is made of a transparent adhesive material, and the embodiment is not limited herein.

Fig. 18 shows a cross-sectional view of a third of the C-C sections of fig. 7. Referring to fig. 18, the electronic device provided in the embodiment of the application further includes a light reflecting module 300, the light reflecting module 300 is disposed on the inner side 131, the light reflecting module 300 and the bottom surface 132 of the groove together form the accommodating cavity 140, and the substrate 210, the light-transmitting packaging layer 230 and the light-transmitting protection layer 240 are connected with the accommodating cavity 140. The application increases the incident light quantity of the solar cell module 220 and improves the utilization rate of sunlight by arranging the light reflecting module 300 so that the incident light is reflected to the solar cell module 220.

In some embodiments, the light reflecting module 300 includes a transparent substrate 310 and a reflective layer 320 disposed on the transparent substrate 310, the reflective layer 320 faces the inner side 131, and the reflective layer 320 is adhered to the inner side 131. The transparent substrate 310 may be tempered glass or microcrystalline glass. The surface of the tempered glass or the glass ceramic is coated with a minute amount of stannous chloride solution, silver nitrate solution and reducing solution to form, for example, a reflective layer 320 (silver layer or aluminum layer).

The reflective layer 320 and the inner side 131 may be bonded by a second adhesive layer 330, wherein the second adhesive layer 330 may be a fluororubber adhesive layer.

In some embodiments, the end of the light reflecting module 300 facing away from the bottom surface 132 of the groove is flush with the light-transmitting protective layer 240. In this way, the solar cell unit 200 may be smooth and excessive with the wristband structure 120, so that the solar cell unit 200 has a more attractive appearance.

Fig. 19 and 20 show the structures of two kinds of condensing devices, respectively. Referring to fig. 19 and 20, the embodiment of the present application further provides a light condensing device, which includes a support assembly 400 and at least one light condensing assembly 500, wherein the light condensing assembly 500 is disposed on the support assembly 400, the support assembly 400 is used for supporting an electronic device, and the light condensing assembly is used for converging light onto a solar cell 200 of the electronic device. Of these, fig. 19 shows one light condensing assembly 500, and fig. 20 shows two light condensing assemblies 500.

Fig. 21 shows the use state of fig. 19, and fig. 22 shows the use state of fig. 20. Arrows in fig. 21 and 22 are used to indicate the path of light. Referring to fig. 21 and 22, when the electronic device is in an unused state (e.g., a state in which a wristwatch is taken off or the like), the solar cell 200 on the electronic device is opposite to the light collecting assembly 500 when the electronic device can be placed on the support assembly 400. Specifically, the light condensation component 500 may be located above the solar cell 200, where the area of the light condensation component 500 is larger than the area of the solar cell 200, and the light energy irradiated on the light condensation component 500 is collected and collected onto the solar cell 200 below the light condensation component 500 by the light condensation component 500, so that the solar cell 200 can receive more light energy, thereby improving the cruising ability of the electronic device.

It can be appreciated that when the electronic device is used in combination with the light condensing device, the area of the solar cell 200 can be reduced, so that the same effect of improving the cruising ability of the electronic device as that of the electronic device without using the light condensing device can be achieved. Since the area of the solar cell 200 is reduced, the cost of the electronic device can be reduced, and the area of the solar cell 200 is reduced, the space occupied by the solar cell 200 in the electronic device is reduced, and thus, the external appearance of the electronic device can be optimized.

It should be noted that, the light condensing device provided in the embodiment of the present application is applicable to any electronic device having the solar cell 200, and may also be applicable to any electronic device in the above embodiment. The structure of the electronic device is detailed in the above embodiments, and will not be described herein.

When the solar cell 200 is provided on the dial structure 110 of the wristwatch, the condensing device shown in fig. 19 is used, which has one condensing unit 500, and the condensing unit 500 is opposite to the solar cell 200 provided on the dial structure 110. When the solar cell units 200 are provided on both the first band 123 and the second band 124 of the wristwatch, a light condensing device having two light condensing units 500 shown in fig. 20 is employed, one light condensing unit 500 being opposite to the solar cell unit 200 on the first band 123 and the other light condensing unit 500 being opposite to the solar cell unit 200 on the second band 124. It can be appreciated that the number of the light condensation assemblies 500 may be three, and accordingly, the solar battery units 200 are disposed on the dial structure 110, the first watchband 123 and the second watchband 124, and the three light condensation assemblies 500 correspond to the solar battery units 200 on the dial structure 110, the first watchband 123 and the second watchband 124, respectively.

In the present application, the support assembly 400 includes a support frame 410, the condensing assembly 500 includes a first condensing lens 510, the first condensing lens 510 is used for condensing light, the first condensing lens 510 is connected to the support frame 410, and the support frame 410 is used for supporting an electronic device (e.g., a wristwatch). The present application fixes the first condenser 510 and the electronic device by the support frame 410, thereby maintaining the first condenser 510 and the solar cell 200 in a relative state so that the light collected by the first condenser 510 is irradiated on the solar cell 200.

The first collecting lens 510 may be connected to the support frame 410 by a detachable connection manner such as a clamping connection, a screw connection, etc.

Fig. 23 shows the structure of the support frame in fig. 19. Referring to fig. 19 and 23, the support frame 410 may include a support plate 411 and a frame 412 coupled to the support plate 411. Wherein, the electronic device may be placed on the support plate 411, and in a specific implementation, a groove matched with the electronic device may be further provided on the support plate 411, and a part of the electronic device is embedded in the groove, so as to avoid the electronic device moving relative to the support plate 411. The first collection optic 510 is coupled to the frame 412.

Fig. 24 shows the structure of the first type of first condensing lens, the second condensing lens and the supporting frame of fig. 19. Referring to fig. 19, 21 and 24, there may be some errors in manufacturing the first condenser lens 510, mounting the first condenser lens 510 or placing the electronic device, which may cause the light collected by the first condenser lens 510 to be difficult to be entirely irradiated on the solar cell 200, resulting in low efficiency of converting the solar cell 200 from light energy into electric energy. Thus, in some embodiments, the light collection assembly 500 further includes a second light collection lens 520, the second light collection lens 520 being disposed on the support frame 410, the second light collection lens 520 being positioned below the first light collection lens 510. The second condenser 520 is configured to receive the light collected by the first condenser 510, and uniformly inject the light collected by the first condenser 510 onto the solar cell 200. In other words, the second condenser lens 520 deflects the obliquely incident light into outgoing light having a uniform distribution of spot intensities, so that the light having a uniform distribution of spot intensities is received on the solar cell unit 200.

In the present application, the first condenser 510, the second condenser 520, and the solar cell 200 may be sequentially disposed along the same axis (e.g., S-axis in fig. 21), the first condenser 510 refracts the parallel light irradiated on the first condenser 510 out of the first condenser 510 to be converged on the second condenser 520 in the form of oblique incident light, and the second condenser 520 totally reflects the oblique incident light into the parallel light to be uniformly incident on the solar cell 200. Thereby, the second condenser lens 520 is made to realize the secondary condensing and homogenizing effects on the first condenser lens 510. That is, the light of a large area is collected on the second condenser lens 520 by the first condenser lens 510 and uniformly distributed on the small-area solar cell unit 200 by the second condenser lens 520, thereby improving the illumination area and the unit illumination intensity on the solar cell unit 200.

In specific implementation, the area of the first condenser lens 510, the area of the second condenser lens 520, and the area of the solar cell unit 200 are sequentially reduced. The area of the first condenser 510 may be 5 to 10 times that of the solar cell 200, thereby making the structure of the condenser device compact. There is no limitation on the focal length of the first condenser lens 510.

The application performs secondary light condensation and light equalization on the light rays emitted by the first light condensing lens 510 through the second light condensing lens 520, so that more light rays are incident on the solar cell unit 200, and the influence of errors such as manufacturing the first light condensing lens 510, installing the first light condensing lens 510 or placing electronic equipment on the efficiency of converting light energy into electric energy of the solar cell unit 200 is reduced.

Fig. 25 shows the structure of the second condenser lens. Referring to fig. 19 and 25, in the present embodiment, the second condenser lens 520 has a first end 521 and a second end 522 opposite to each other, the cross-sectional area of the second condenser lens 520 decreases sequentially from the first end 521 to the second end 522, the first end 521 faces the first condenser lens 510, the second end 522 faces the solar cell 200, and the second end 522 is matched with the solar cell 200.

Illustratively, the second condenser lens 520 may be a truncated cone or a quadrangular prism, the second condenser lens 520 having a large end and a small end, the first end 521 being the large end of the second condenser lens 520, and the second end 522 being the small end of the second condenser lens 520. The light collected by the first collecting mirror 510 may enter the first end 521, the second end 522 has the same shape as the solar cell 200, the second end 522 has the same size as the solar cell 200, and the second end 522 coincides with the solar cell 200. Therefore, the structure is compact, and the utilization rate of light is high.

In some embodiments, the second end 522 abuts against the solar cell unit 200, that is, there is no gap between the second end 522 and the solar cell unit 200, so that the electronic device can be fixed by the second light collecting lens 520, and the electronic device is prevented from falling off from the light collecting device.

Fig. 26 shows the structure of the second type of first condensing lens, second condensing lens and supporting frame of fig. 19. Referring to fig. 26, in order to facilitate mounting of the second condenser lens 520, in some embodiments, the support frame 410 has a mounting portion 413 thereon, the mounting portion 413 has a mounting hole 4131 thereon, and the second condenser lens 520 is positioned within the mounting hole 4131. Thus, the second condenser lens 520 can be fixed through the mounting hole 4131, which is easy to operate, and the second condenser lens 520 can be mounted conveniently. Wherein the second condenser lens 520 may be encapsulated in the mounting hole 4131 using an optical cement.

In order to transmit the light in the second condenser 520 to the outside of the mounting portion 413, the total reflection of the light by the second condenser 520 is improved, and the light loss is reduced. In one possible implementation, the light loss may be reduced by selecting the mounting portion 413 of a different material, and the mounting portion 413 may be one of a rubber mount, a resin mount, a plastic mount, or a metal mount, for example. In another possible implementation, a backlight may be added, and illustratively, a backlight film may be disposed within the mounting hole 4131. In a third possible implementation, the mounting portion 413 may be one of a rubber mount, a resin mount, a plastic mount, or a metal mount, and a backlight film is disposed in the mounting hole 4131.

In the condensing device provided by the embodiment of the application, the first condensing lens 510 is a fresnel lens, and the second condensing lens 520 is one of a fresnel lens, a prism and a concave lens. The shape of the fresnel lens may be the same as that of the solar cell 200, for example, when the solar cell 200 is a rectangular parallelepiped, the fresnel lens may be a linear fresnel lens; when the solar cell 200 is cylindrical, the fresnel lens may be a circular fresnel lens. The material of the second condenser lens 520 may be polyolefin, resin, optical glass, or the like.

The Fresnel lens can also be called a threaded lens, and is formed by injection molding of polyolefin materials; or the fresnel lens may be made of glass. One surface of the Fresnel lens is a smooth surface, and the other surface is inscribed with concentric circles from small to large. The fresnel lens is easy to be shaped and thin in weight as compared with the glass lens.

In a specific implementation, the first condenser lens 510 is a fresnel lens and the second condenser lens 520 is a prism. The concentric circles of the first condenser lens 510 face the first end 521 of the second condenser lens 520, and the second end 522 of the second condenser lens 520 abuts against the solar cell unit 200. The area of the cross section of the second condenser lens 520 from the first end 521 to the second end 522 (for example, a cross section in a direction perpendicular to the first end 521 to the second end 522) sequentially decreases.

The shape of the first end 521 is the same as the shape of the spot on the focal plane of the first condenser lens 510, and the size of the first end 521 is the same as the size of the spot on the focal plane of the first condenser lens 510, and the spot is located on the first end 521. That is, the light collected by the first condenser 510 may all enter the second condenser 520, thereby improving the light utilization.

Because of the strong light gathering capability of the Fresnel lens, users may get burned. In some embodiments, a bezel is positioned on the support frame 410 by which to enclose the light gathering assembly 500, preventing a user from contacting the light gathering assembly 500 within the bezel.

The solar cell 200 converts light energy into electric energy, and generates heat. In some embodiments, the light condensing device further includes a heat dissipation assembly 600, the heat dissipation assembly 600 is located on the support frame 410, and the heat dissipation assembly 600 is used for abutting against the electronic device to dissipate heat of the electronic device. In this way, the heat dissipation assembly 600 dissipates heat from the electronic device to reduce the performance impact of heat generated when the solar cell 200 converts light energy into electrical energy.

When in use, the heat dissipation assembly 600 is opposite to the solar cell 200, so that the heat dissipation assembly 600 can timely take away heat generated when the solar cell 200 is converted from light energy into electric energy. The heat sink assembly 600 is positioned on the support plate 411 of the support frame 410, thereby facilitating the contact of the heat sink assembly 600 with the electronic device on the support plate 411.

In particular implementations, the heat sink assembly 600 is one of a hot plate, a metal plate, a graphite sheet, and a liquid cooled heat sink assembly. The form of the heat dissipation assembly 600 may be adaptively selected according to design requirements, and the present embodiment is not limited herein. The hot plate, the metal plate and the graphite sheet may be attached to the support plate 411 by means of bonding or embedded in the support plate 411.

The heat sink assembly 600 is illustrated in the drawings as a liquid-cooled heat sink assembly. Specifically, a cavity 4111 may be disposed on the support plate 411, where the cavity 4111 is formed by integral injection molding or mechanical cutting, and a cooling liquid is introduced into the cavity 4111, so that the cooling liquid takes away heat generated when the solar cell 200 is converted from light energy into electric energy, thereby dissipating heat of the electronic device. The top of the cavity 4111 is reserved with a receiving groove 4112 for placing the dial structure 110 or the watchband structure 120. Dial structure 110 or band structure 120 is fixed by receiving slot 4112.

Referring to fig. 19, the condensing device provided by the embodiment of the application further includes a photosensitive assembly 700, the photosensitive assembly 700 is disposed on the support assembly 400, and the photosensitive assembly 700 is used for detecting intensity of light. The photosensitive assembly 700 may include a photosensitive element for detecting intensity of light and a prompter for prompting intensity of light.
