Description

Technical Field

[0001] The present application relates to the technical field of wearable devices, and in particular to an XR device and a wireless charging system. Background Art

[0002] Currently, XR (Extended Reality) products are generally charged via wired or PogoPin magnetic charging, which requires a dedicated charging port or metal contacts to be set up on the product.

[0003] For XR products with multiple functions and high computing power requirements, in order to meet a certain battery life, the battery capacity is larger, usually several thousand mAh (milli Ampere hour), and the charging speed and power requirements are high. Basically, a USB interface wired charging solution is used.

[0004] For smart glasses with fewer functions and low computing power requirements, due to the limited size and weight, the battery capacity is small, usually tens to hundreds of mAh, and Pogo Pin magnetic charging is generally used.

[0005] For the method of using USB interface wired charging or Pogo Pin magnetic charging, on the one hand, you cannot get rid of the constraints of cables and charging is not flexible enough. On the other hand, the charging port or contacts have a certain impact on the appearance of the product and are not conducive to the waterproof and dustproof design of the product.

[0006] Some smart glasses have adopted wireless charging solutions, which are more flexible to charge, more beautiful, and more waterproof and dustproof. However, the charging power is low, and the position matching of the transmitting coil and the receiving coil is required to be high. A slight deviation in the position will lead to a significant reduction in charging efficiency and charging power. Summary of the invention

[0007] The embodiments of the present application provide an XR device and a wireless charging system, which can improve the wireless charging power and wireless charging efficiency of the XR device, reduce the position matching requirements for the wireless charging transmitting coil and the wireless charging receiving coil, and increase the position freedom of the XR device during wireless charging.

[0008] An embodiment of the present application provides an XR device, including:

[0009] Eyeglass frames;

[0010] A lens, arranged on the spectacle frame;

[0011] The wireless charging receiving coil is arranged at the periphery of the lens, and the wireless charging receiving coil is used to receive electric energy wirelessly.

[0012] The present application also provides a wireless charging system, including:

[0013] A charging base, the charging base comprising a wireless charging transmitting coil, the wireless charging transmitting coil being used to transmit electric energy wirelessly;

[0014] An XR device, wherein the XR device is the above-mentioned XR device, and the wireless charging receiving coil of the XR device is electromagnetically coupled with the wireless charging transmitting coil to receive the electric energy transmitted by the wireless charging transmitting coil.

[0015] In the XR device provided by the embodiment of the present application, by setting the wireless charging receiving coil at the periphery of the lens, the area of ​​the wireless charging receiving coil can be increased, thereby improving the wireless charging power and wireless charging efficiency, and can reduce the position matching requirements between the wireless charging transmitting coil and the wireless charging receiving coil, thereby increasing the position freedom of the XR device during wireless charging.

[0029] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0030] The embodiments of the present application provide a wireless charging system for XR (Extended Reality) and wearable devices. Among them, XR is a general term for AR (Augmented Reality), VR (Virtual Reality), and MR (Mixed Reality). Users can experience various functions that combine virtuality and reality through XR devices. In practical applications, XR devices can be various wearable devices such as smart glasses, AR glasses, VR helmets, VR glasses, etc. In the following embodiments, the XR device of the present application is described by taking smart glasses as an example.

[0031] refer to Figure 1 , Figure 1 1 is a schematic diagram of a first structure of the smart glasses 100 according to an embodiment of the present application. The smart glasses 100 include a glasses frame 10 , a lens 20 , and a wireless charging receiving coil 30 .

[0032] The glasses frame 10 forms the overall frame of the smart glasses 100. The glasses frame 10 can be used to mount structures such as the lenses 20, and to be worn by the user. In practical applications, the glasses frame 10 can be made of a material with characteristics such as light weight, high strength, heat insulation, and insulation, such as polycarbonate (PC) or carbon fiber material.

[0033] The lens 20 is disposed on the spectacle frame 10. Figure 2 , Figure 2 for Figure 1 Schematic diagram of the structure of the lens 20 of the smart glasses shown. The lens 20 can transmit ambient light, so the user can observe the real image of the external environment through the lens 20. In addition, in some embodiments, the lens 20 can also display the virtual image generated by the smart glasses 100, so that the user can also observe the virtual image through the lens 20.

[0034] The wireless charging receiving coil 30 is disposed at the periphery of the lens 20. The wireless charging receiving coil 30 is used to receive electrical energy wirelessly, so as to wirelessly charge the smart glasses 100. In practical applications, the wireless charging receiving coil 30 may be a wound coil, for example, wound with a thin copper wire, or may be a coil formed by FPC (Flexible Printed Circuit) wiring.

[0035] It can be understood that in the smart glasses 100, the area of ​​the lens 20 is relatively large, and the lens 20 can be understood as the only large area of ​​the smart glasses 100. By arranging the wireless charging receiving coil 30 at the periphery of the lens 20, the wireless charging receiving coil 30 can form a large-area receiving coil. In actual applications, the area of ​​a single receiving coil can reach 20 cm 2 , and its shape is close to a rectangle or an ellipse. Therefore, compared with the traditional smart glasses, the area of ​​the wireless charging receiving coil 30 can be increased.

[0036] In some embodiments, reference Figure 3 , Figure 3 for Figure 1 A schematic structural diagram of the lenses and lens frames of the smart glasses 100 is shown.

[0037] The smart glasses 100 further include a lens frame 40. The lens frame 40 is wrapped around the periphery of the lens 20 and forms a gap 40a with the periphery of the lens 20. In practical applications, the lens frame 40 can be formed of a light-weight and high-strength material, for example, the lens frame 40 can be made of a metal material, or a non-metal material such as a polycarbonate material, a carbon fiber material, or the like.

[0038] It can be understood that the lens frame 40 is wrapped around the periphery of the lens 20. Therefore, on the one hand, it can improve the overall structural strength of the lens 20 and enhance the pressure resistance, impact resistance and other properties of the lens 20. On the other hand, it can also protect the periphery of the lens 20 and prevent the periphery of the lens 20 from being damaged.

[0039] The wireless charging receiving coil 30 is disposed in the gap 40a, so that the wireless charging receiving coil 30 is disposed at the periphery of the lens 20. Therefore, a large-area wireless charging receiving coil 30 can be formed, and the lens frame 40 can protect the wireless charging receiving coil 30, and the wireless charging receiving coil 30 can also be hidden, and the wireless charging receiving coil 30 cannot be observed from the outside of the smart glasses 100.

[0040] In some embodiments, reference Figure 4 , Figure 4 for Figure 2 The side view of the lens 20 is shown. A groove 20a is provided at the periphery of the lens 20, and the wireless charging receiving coil 30 is embedded in the groove 20a, so that the wireless charging receiving coil 30 is provided at the periphery of the lens 20, thereby forming a large-area receiving coil. It can be understood that the wireless charging receiving coil 30 is embedded in the periphery of the lens 20.

[0041] In practical applications, the groove 20a can form a full circle around the periphery of the lens 20 to facilitate the installation of the wireless charging receiving coil 30. The depth and width of the groove 20a can be set according to actual needs, so that the groove 20a is sufficient to accommodate the wireless charging receiving coil 30.

[0042] refer to Figure 5 , Figure 5 This is a second structural diagram of the smart glasses 100 according to an embodiment of the present application.

[0043] The lens 20 includes a first lens 21 and a second lens 22, which are spaced apart on the spectacle frame 10. In practical applications, the material, shape, size, thickness, etc. of the first lens 21 and the second lens 22 can be the same, or different according to actual needs.

[0044] The wireless charging receiving coil 30 includes a first receiving coil 31 and a second receiving coil 32. The first receiving coil 31 is disposed at the periphery of the first lens 21. The second receiving coil 32 is disposed at the periphery of the second lens 22. The first receiving coil 31 and the second receiving coil 32 are both used to receive electrical energy wirelessly.

[0045] Therefore, the areas of the first lens 21 and the second lens 22 can be reasonably utilized to form the first receiving coil 31 and the second receiving coil 32 , thereby increasing the area of ​​the wireless charging receiving coil 30 .

[0046] Continue to refer Figure 5 The eyeglass frame 10 includes a frame 11, a first temple 12 and a second temple 13. The frame 11, the first temple 12 and the second temple 13 can be formed by polycarbonate material or carbon fiber material.

[0047] The first lens 21 and the second lens 22 are spaced apart in the frame 11. The first temple 12 is connected to one side of the frame 11, and the second temple 13 is connected to the other side of the frame 11. The first temple 12 and the second temple 13 are used for the smart glasses 100 to be worn on the user's head.

[0048] In practical applications, the frame 11 , the first temple 12 , and the second temple 13 may all be hollow structures, so that some functional components or wiring can be arranged in the frame 11 , the first temple 12 , and the second temple 13 .

[0049] The smart glasses 100 of the present application can be designed with a corresponding battery capacity according to the hardware stacking space of the product, the function of the product, and the required computing power. In practical applications, a battery can be set in one side of the temple of the smart glasses 100, or in both sides of the temple of the smart glasses 100.

[0050] For example, in some embodiments, for the manner of setting a battery in one side of the temple of the smart glasses 100, refer to Figure 6 and Figure 7 , Figure 6 Schematic diagram of the third structure of the smart glasses 100 according to an embodiment of the present application. Figure 7 for Figure 6 Schematic diagram of the circuit structure of the smart glasses 100.

[0051] The smart glasses 100 also include a first battery 51, a first receiving chip 33 and a second receiving chip 34. The first battery 51 is disposed in the first temple 12. The shape and size of the first battery 51 can be adaptively designed according to the space inside the first temple 12. The first battery 51 is used to store electrical energy and to power the smart glasses 100. The first receiving chip 33 and the second receiving chip 34 are both disposed in the second temple 13. The first receiving chip 33 and the second receiving chip 34 are both wireless charging receiving chips, which can be used to process wireless charging signals.

[0052] The first receiving chip 33 is electrically connected to the first receiving coil 31 and the first battery 51. The first receiving coil 31 is used to charge the first battery 51 through the first receiving chip 33. The second receiving chip 34 is electrically connected to the second receiving coil 32 and the first battery 51. The second receiving coil 32 is used to charge the first battery 51 through the second receiving chip 34.

[0053] When a battery is set in one side of the temple of the smart glasses 100, for example, when a first battery 51 is set in the first temple 12, the capacity of the first battery 51 is usually small, for example, the capacity of the first battery 51 can be less than 200mAh, and the corresponding charging power is also small, usually less than 2W. In this case, a wireless charging solution based on the NFC (Near Field Communication) standard can be selected, and the number of windings of the first receiving coil 31 and the second receiving coil 32 can be designed according to the design requirements of the NFC receiving chip.

[0054] In practical applications, the smart glasses 100 may further include a first mainboard 61. The first mainboard 61 is disposed in the second temple 13. The shape and size of the first mainboard 61 may be adaptively designed according to the space inside the second temple 13. The first receiving chip 33 and the second receiving chip 34 are both disposed on the first mainboard 61. It is understandable that electronic devices such as a processor and a memory may also be disposed on the first mainboard 61, which will not be described in detail herein.

[0055] In practical applications, the smart glasses 100 may further include an FPC 70. The FPC 70 is disposed in the frame 11, the first temple 12, and the second temple 13. The FPC 70 is used to electrically connect the first receiving coil 31 and the first receiving chip 33, the first receiving chip 33 and the first battery 51, and to electrically connect the second receiving coil 32 and the second receiving chip 34, the second receiving chip 34 and the first battery 51.

[0056] It is understandable that in actual applications, the frame 11, the first temple 12, and the second temple 13 can all be formed of non-transparent materials. Therefore, the first receiving chip 33, the second receiving chip 34, the first battery 51, the first mainboard 61, and the FPC 70 can all be hidden inside the smart glasses 100, and these structures cannot be observed from the outside, thereby ensuring the aesthetics of the smart glasses 100.

[0057] In some other embodiments, for the method of setting batteries in both temples of the smart glasses 100, refer to Figure 8 and Fig. 9 , Figure 8 1 is a fourth structural schematic diagram of the smart glasses 100 according to an embodiment of the present application. Fig. 9 for Figure 8 A first circuit structure schematic diagram of the smart glasses 100 is shown.

[0058] The smart glasses 100 include a first battery 51 , a second battery 52 , a first receiving chip 33 , and a second receiving chip 34 .

[0059] The first battery 51 is disposed in the first temple 12, and the shape and size of the first battery 51 can be adaptively designed according to the space inside the first temple 12. The second battery 52 is disposed in the second temple 13, and the shape and size of the second battery 52 can be adaptively designed according to the space inside the second temple 13. Both the first battery 51 and the second battery 52 are used to store electrical energy and to supply power to the smart glasses 100.

[0060] The first receiving chip 33 is disposed in the first temple 12. The first receiving chip 33 is electrically connected to the first receiving coil 31 and the first battery 51. The first receiving coil 31 is used to charge the first battery 51 through the first receiving chip 33.

[0061] The second receiving chip 34 is disposed in the second temple 13. The second receiving chip 34 is electrically connected to the second receiving coil 32 and the second battery 52. ​​The second receiving coil 32 is used to charge the second battery 52 through the second receiving chip 34.

[0062] Among them, the first receiving chip 33 and the second receiving chip 34 are both wireless charging receiving chips, which can be used to process wireless charging signals.

[0063] In practical applications, for XR devices such as VR helmets and VR glasses, a larger battery can be provided, for example, a first battery 51 is provided in the first temple 12 and a second battery 52 is provided in the second temple 13, or the first battery 51 and the second battery 52 can be provided at the wearing position such as the back of the head or the top of the head of the VR helmet. The total capacity of the first battery 51 and the second battery 52 is usually large, for example, the total capacity can reach several thousand mAh, and the corresponding charging power is relatively large, usually the charging power is above 2W, for example, the charging power can reach 50W or even higher. In this case, a wireless charging solution based on the QI standard (a wireless charging standard launched by the Wireless Power Consortium) can be selected, and the number of windings of the first receiving coil 31 and the second receiving coil 32 can be designed according to the design requirements of the QI receiving chip.

[0064] In some embodiments, reference Fig.10 , Fig.10 for Figure 8 A second circuit structure schematic diagram of the smart glasses 100 is shown.

[0065] The first receiving chip 33 is also electrically connected to the second battery 52, and the first receiving coil 31 is also used to charge the second battery 52 through the first receiving chip 33. The second receiving chip 34 is also electrically connected to the first battery 51, and the second receiving coil 32 is also used to charge the first battery 51 through the second receiving chip 34.

[0066] Therefore, the first receiving coil 31 can charge both the first battery 51 and the second battery 52. ​​Similarly, the second receiving coil 32 can charge both the second battery 52 and the first battery 51. Thus, the smart glasses 100 can be wirelessly charged in a variety of different ways, thereby improving the flexibility of wireless charging.

[0067] It is understandable that in actual applications, there may be a situation where one of the first battery 51 and the second battery 52 has more power and the other has less power, for example, the power of the first battery 51 is 50% and the power of the second battery 52 is 90%. In this case, the battery with less power can be charged simultaneously through the first receiving coil 31 and the second receiving coil 32, so that the battery with less power can be fully charged quickly, thereby improving the charging efficiency.

[0068] In some embodiments, continue to refer to Figure 8 The smart glasses 100 also include a first main board 61 and a second main board 62 .

[0069] The first mainboard 61 is disposed in the first temple 12. The shape and size of the first mainboard 61 can be adaptively designed according to the space inside the first temple 12. The first receiving chip 33 is disposed on the first mainboard 61.

[0070] The second main board 62 is disposed in the second temple 13. The shape and size of the second main board 62 can be adaptively designed according to the space inside the second temple 13. The second receiving chip 34 is disposed on the second main board 62.

[0071] Therefore, the internal space of the smart glasses 100 can be reasonably utilized to make the layout of various electronic devices more compact and improve the utilization rate of the internal space.

[0072] In some embodiments, continue to refer to Fig. 9 The smart glasses 100 further include an FPC 70. The FPC 70 is disposed in the frame 11, the first temple 12, and the second temple 13. The FPC 70 is used to electrically connect the first receiving coil 31 and the first receiving chip 33, the first receiving chip 33 and the first battery 51, and to electrically connect the second receiving coil 32 and the second receiving chip 34, the second receiving chip 34 and the second battery 52.

[0073] In some embodiments, continue to refer to Fig.10 When the first receiving chip 33 is also electrically connected to the second battery 52 and the second receiving chip 34 is also electrically connected to the first battery 51, the electrical connection between the first receiving chip 33 and the second battery 52 can be achieved through the FPC 70, and the electrical connection between the second receiving chip 34 and the first battery 51 can be achieved through the FPC 70.

[0074] It is understandable that in actual applications, the frame 11, the first temple 12, and the second temple 13 can all be formed of non-transparent materials. Therefore, the first receiving chip 33, the second receiving chip 34, the first battery 51, the second battery 52, the first mainboard 61, the second mainboard 62, and the FPC 70 can all be hidden inside the smart glasses 100, and these structures cannot be observed from the outside, thereby ensuring the aesthetics of the smart glasses 100.

[0075] According to the smart glasses 100 described in the above embodiments of the present application, the following technical effects can be achieved:

[0076] First, the area of ​​the wireless charging receiving coil 30 can be increased, for example, the area of ​​the first receiving coil 31 and the second receiving coil 32 can be increased, so that the wireless charging power and the wireless charging efficiency can be greatly improved, and the time required for wireless charging of the smart glasses 100 can be greatly shortened.

[0077] Secondly, since the area of ​​the wireless charging receiving coil 30 is increased, when the smart glasses 100 are wirelessly charged, the position matching requirements between the wireless charging transmitting coil (such as the wireless charging transmitting coil of the charging base) and the wireless charging receiving coil 30 can be reduced. When the positions of the two are not strictly aligned or there is a certain deviation, the impact on the wireless charging is not significant, thereby increasing the position freedom of the smart glasses 100 during wireless charging.

[0078] Thirdly, since the main board and the electronic components on the main board are arranged in the temples, for example, in the first temple 12 and the second temple 13, and the first receiving coil 31 and the second receiving coil 32 are arranged in the frame 11, the first receiving coil 31 and the second receiving coil 32 can be kept away from the main board and the electronic components on the main board. Therefore, there is no need to add materials such as ferrite to increase the magnetic field density of wireless charging, which can save costs and reduce the overall weight of the smart glasses 100.

[0079] Fourthly, since the first receiving coil 31 and the second receiving coil 32 are arranged in the frame 11, and the material of the first receiving coil 31 and the second receiving coil 32 is generally metal, such as a coil wound with copper wire, the strength and reliability of the frame 11 can be enhanced by embedding the metal material, thereby extending the service life of the smart glasses 100.

[0080] Fifthly, the first receiving coil 31 and the second receiving coil 32 are arranged in the frame 11, thereby reducing the internal space occupied by the first temple 12 and the second temple 13. The saved internal space can be used to expand the battery capacity, thereby increasing the battery life of the smart glasses 100 and solving the pain point of short battery life of smart glasses in the industry.

[0081] Sixthly, the smart glasses 100 are wirelessly charged via the wireless charging receiving coil 30 , so there is no need to set a charging port and Pogo Pin metal contacts, which can improve the product aesthetics of the smart glasses 100 .

[0082] An embodiment of the present application also provides a wireless charging system, which can be used to wirelessly charge an XR device, such as wirelessly charging the above-mentioned smart glasses 100.

[0083] refer to Fig.11 , Fig.11 Schematic diagram of the circuit structure of the wireless charging system of the embodiment of the present application. The wireless charging system includes a charging base 200 and an XR device, and the XR device is, for example, the smart glasses 100 described above.

[0084] The charging base 200 includes a wireless charging transmitting coil 201 and a transmitting chip 202. The charging base 200 can be connected to an external power source, and the transmitting chip 202 provides power to the wireless charging transmitting coil 201, and the wireless charging transmitting coil 201 transmits the power to the outside world wirelessly.

[0085] When the smart glasses 100 are wirelessly charged, the wireless charging receiving coil 30 is electromagnetically coupled with the wireless charging transmitting coil 201 to receive the electric energy transmitted by the wireless charging transmitting coil 201. In practical applications, the relative positions of the charging stand 200 and the smart glasses 100 can be moved, so any one of the first receiving coil 31 and the second receiving coil 32 can be electromagnetically coupled with the wireless charging transmitting coil 201, thereby realizing wireless charging of the smart glasses 100.

[0086] refer to Fig.12 , Fig.12 for Fig.11 An example circuit structure diagram of a wireless charging system is shown. Among them, the wireless charging transmitting coil 201 includes a first transmitting coil 201a and a second transmitting coil 201b. The transmitting chip 202 includes a first transmitting chip 202a and a second transmitting chip 202b. The first transmitting coil 201a is electrically connected to the first transmitting chip 202a, and the second transmitting coil 201b is electrically connected to the second transmitting chip 202b. When the smart glasses 100 are wirelessly charged, the first receiving coil 31 is electromagnetically coupled with the first transmitting coil 201a to receive the electric energy transmitted by the first transmitting coil 201a; the second receiving coil 32 is electromagnetically coupled with the second transmitting coil 201b to receive the electric energy transmitted by the second transmitting coil 201b. Therefore, the smart glasses 100 can be wirelessly charged by two receiving coils at the same time, further improving the wireless charging efficiency. It can be understood that in actual applications, only one pair of transmitting coils and receiving coils can be selected for charging as needed.

[0087] In practical applications, the charging stand 200 can be a dedicated charging device for the smart glasses 100. The area of ​​the first transmitting coil 201a is the same as or similar to the area of ​​the first receiving coil 31, and the area of ​​the second transmitting coil 201b is the same as or similar to the area of ​​the second receiving coil 32, so as to achieve a better coupling effect. When wireless charging is performed, the positions of the first transmitting coil 201a and the first receiving coil 31 are matched, and the positions of the second transmitting coil 201b and the second receiving coil 32 are matched, and the gap is appropriate to improve the charging efficiency.

[0088] In the description of this application, it should be understood that terms such as "first" and "second" are only used to distinguish similar objects and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features.

[0089] It should be noted that in the embodiments of the present application, "electrical connection" can be achieved by direct connection between two electrical components to achieve electrical connection, or it can be achieved by indirect connection to achieve electrical connection. For example, A and B are electrically connected, which can be achieved by direct connection between A and B, or it can be achieved by indirect connection between A and B through one or more other electrical components.

Specific examples are used in this article to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the present application. At the same time, for those skilled in the art, according to the ideas of the present application, there will be changes in the specific implementation methods and application scopes. In summary, the content of this specification should not be understood as limiting the present application.
