Description

Technical Field

[0001] This application relates to the field of smart glasses technology, and more specifically, to a frame and smart glasses having the frame. Background Technology

[0002] Smart glasses are products that connect the real and virtual worlds. Using everyday eyeglasses as a medium, they combine projection, augmented reality, and other technologies to create a virtual-real fusion atmosphere, providing a more immersive experience. As smart glasses technology matures, they are not only used to enhance entertainment but also in education, healthcare, the military, and many other fields, leading to better demonstrations and teaching. Therefore, smart glasses are receiving increasing attention and importance.

[0003] Smart glasses charging solutions come in two types: wired and wireless. Wired charging requires a charging cable to connect to an adapter, while wireless charging eliminates the need for a cable and adapter, making it more convenient. Wireless charging is achieved by using contact springs in the glasses case. When the smart glasses are placed in the case, the contact springs on the glasses make contact with those in the case, initiating wireless charging. However, this method only allows wireless charging when the smart glasses are inside the case, limiting its flexibility and freedom of movement. Summary of the Invention

[0004] This application provides a frame and smart glasses, which at least address the problems of limited freedom of wireless charging and poor flexibility in smart glasses.

[0005] The eyeglass frame according to this application includes a battery module, a frame, and temples. The frame is provided with a first charging receiver. The temples are connected to the frame and are provided with a second charging receiver. When the eyeglass frame is folded and placed on the charging base, the wireless charging transmitter of the charging base can cooperate with the first charging receiver to charge the battery module; when the eyeglass frame is unfolded and placed on the charging base, the wireless charging transmitter can cooperate with the second charging receiver to charge the battery module.

[0006] The smart glasses according to this application include lenses and a frame. The lenses are mounted on the frame of the frame. The frame includes a battery module, a frame, and temples. The frame is provided with a first charging receiver. The temples are connected to the frame and are provided with a second charging receiver. When the frame is folded and placed on the charging base, the wireless charging transmitter of the charging base can cooperate with the first charging receiver to charge the battery module; when the frame is unfolded and placed on the charging base, the wireless charging transmitter can cooperate with the second charging receiver to charge the battery module.

[0007] The eyeglass frame and smart glasses of this application, by setting a first charging receiver at the frame, generate an induced current by the magnetic lines of force generated by the wireless charging transmitter of the charging base when the frame is folded and placed on the charging base, thereby charging the battery module. The eyeglass frame and smart glasses of this application also include a second charging receiver installed at the temples. When the frame is unfolded and placed on the charging base, the magnetic lines of force generated by the wireless charging transmitter generate an induced current by the magnetic lines of force generated by the wireless charging transmitter, thereby charging the battery module. Thus, the eyeglass frame and smart glasses of this application, through the two first and second charging receivers located in different positions, allow the wireless charging transmitter to cooperate with the first and second charging receivers in both folded and unfolded states of the frame, realizing wireless charging of the smart glasses in different placement configurations. This makes the wireless charging configuration of the smart glasses more flexible and offers greater freedom of choice.

[0018] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the embodiments of this application, and should not be construed as limiting the embodiments of this application.

[0019] Please see Figure 1 This application provides a glasses frame 100, which includes a frame 10, temples 30, and a battery module 40. The frame 10 is provided with a first charging receiver 50. The temples 30 are connected to the frame 10 and are provided with a second charging receiver 70. Specifically: when the glasses frame 100 is folded and placed on a charging base 200, the wireless charging transmitter 203 of the charging base 200 can cooperate with the first charging receiver 50 to charge the battery module 40; when the glasses frame 100 is unfolded and placed on the charging base 200, the wireless charging transmitter 203 can cooperate with the second charging receiver 70 to charge the battery module 40.

[0020] Specifically, the temples 30 include two temples, each mounted at one end of the frame 10 and rotatably connected to both ends of the frame 10. The folded state is defined as follows: when the two temples 30 are folded until the distance between the frame 10 and the two temples 30 is at its minimum; or, when the two temples 30 are folded until their extension directions are substantially the same (or when the two temples 30 are folded to overlap and stack with the frame 10), the folded state is defined as follows. Figure 2 As shown. The unfolded state is defined as when the frame 100 can be placed on the charging base 200 without external force, and the temples 30 are not fully folded. That is, any state of the frame 100 other than the folded state is considered the unfolded state. For example, Figure 1 and Figure 3The frame 100 shown is in the unfolded state.

[0021] Please see Figure 1 The charging stand 200 includes a base body 201 and a wireless charging transmitter 203 housed within the base body 201. When wireless charging of the battery module 40 is required, the eyeglass frame 100 can be placed on the base body 201 in either a folded or unfolded state. The magnetic lines of force 205 generated by the wireless charging transmitter 203 are perpendicular to the base body 201.

[0022] Specifically, when the wireless charging transmitter 203 can cooperate with the first charging receiver 50 to charge the battery module 40, the magnetic field lines 205 generated by the wireless charging transmitter 203 pass through the first charging receiver 50, and the first charging receiver 50 generates an induced current in the magnetic field to charge the battery module 40. At this time, the magnetic field lines 205 generated by the wireless charging transmitter 203 do not pass through the second charging receiver 70 installed on the temple 30. When the frame 100 is placed in a folded state on the base body 201, the wireless charging between the second charging receiver 70 and the wireless charging transmitter 203 does not work. Figure 2 As shown. When the wireless charging transmitter 203 can cooperate with the second charging receiver 70 to charge the battery module 40, the magnetic field lines 205 generated by the wireless charging transmitter 203 pass through the second charging receiver 70, and the second charging receiver 70 generates an induced current in the magnetic field to charge the battery module 40. At this time, the magnetic field lines 205 generated by the wireless charging transmitter 203 do not pass through the first charging receiver 50 installed on the frame 10. When the frame 100 is placed on the base body 201 in an unfolded state, the wireless charging between the first charging receiver 50 and the wireless charging transmitter 203 does not work. Figure 1 and Figure 3 As shown.

[0023] When smart glasses are charged wirelessly, wireless charging eliminates the need for data cables and adapters. This is achieved by placing contact points in the glasses case. When the smart glasses are placed in the case, the contact points on the glasses make contact with those in the case, initiating wireless charging. However, this method only allows wireless charging when the smart glasses are inside the case, limiting charging flexibility and freedom of movement.

[0024] The eyeglass frame 100 of this application, by providing a first charging receiver 50 at the frame 10, generates an induced current by the magnetic lines of force 205 generated by the wireless charging transmitter 203 of the charging base 200 passing through the first charging receiver 50 when the eyeglass frame 100 is placed in a folded state on the charging base 200, thereby charging the battery module 40. The eyeglass frame 100 also includes a second charging receiver 70 installed at the temple 30. When the eyeglass frame 100 is placed in an unfolded state on the charging base 200, the magnetic lines of force 205 generated by the wireless charging transmitter 203 pass through the second charging receiver 70, thereby charging the battery module 40. Therefore, the frame 100 of this application enables the wireless charging transmitter 203 to cooperate with the first charging receiver 50 and the second charging receiver 70 in different positions when the frame 100 is in a folded or unfolded state, thereby realizing wireless charging of the smart glasses 1000 in different placement forms. The form of wireless charging of the smart glasses 1000 is more flexible and has a higher degree of freedom.

[0025] The charging stand 200 can be an eyeglass case or a charging base. When the charging stand 200 is an eyeglass case, the eyeglass frame 100 can be placed in the eyeglass case in an unfolded state for wireless charging when the eyeglass case is in an open or semi-open state. When the charging stand 200 is a charging base, the charging base can be a three-dimensional structure with a circular, square, or other shapes.

[0026] Please combine Figure 1 and Figure 4 Specifically, in some embodiments, the wireless charging transmitter 203 may include a wireless charging transmitting coil 2031 and a first electronic device 2033. The first electronic device 2033 includes a metal-oxide-semiconductor field-effect transistor (MOS transistor) and a first capacitor C1. The MOS transistor may include four transistors, denoted as MOS transistor 1, MOS transistor 2, MOS transistor 3, and MOS transistor 4. MOS transistors 1 and 3 are connected in series and connected to one end of the wireless charging transmitting coil 2031. MOS transistors 2 and 4 are connected in series and connected to the other end of the first capacitor C1. The series-connected MOS transistors 1 and 3, and the series-connected MOS transistors 2 and 4, are connected in parallel to form a full-bridge inverter circuit. The schematic diagram of the wireless charging circuit of the wireless charging transmitter 203 is shown below. Figure 4As shown in the middle left figure, the DC power supplied by the DC power supply is converted into AC power by a full-bridge inverter circuit composed of MOSFET 1, MOSFET 2, MOSFET 3 and MOSFET 4. The AC power is then transmitted through a resonant circuit composed of the first capacitor C1 and the wireless charging transmitting coil 2031. The wireless charging transmitting coil 2031 transmits electrical energy, and the energy transmitted by the wireless charging transmitting coil 2031 is coupled by the first charging receiver 50 or the second charging receiver 70. The resonant circuit composed of the first capacitor C1 and the wireless charging transmitting coil 2031 can improve the wireless power transmission efficiency.

[0027] In some embodiments, the battery module 40 is disposed on the frame 10 and / or temple 30 and is electrically connected to the first charging receiver 50 and the second charging receiver 70.

[0028] Specifically, in some embodiments, the number of battery modules 40 may include one. In one example, the battery module 40 may be installed on the frame 10, and the battery module 40 is electrically connected to both the first charging receiver 50 and the second charging receiver 70. In another example, the battery module 40 may be installed on the temple 30, and the battery module 40 is electrically connected to both the first charging receiver 50 and the second charging receiver 70.

[0029] In other embodiments, the number of battery modules 40 may include two, one of which is mounted on the frame 10 and electrically connected to the first charging receiver 50, and the other is mounted on the temple 30 and electrically connected to the second charging receiver 70.

[0030] In one example, the battery module 40 can be installed inside the frame 10 and / or temple 30. For example, before assembling the frame 10 and / or temple 30 into a closed structure, the battery module 40 is fixedly installed within the receiving space of the closed structure of the frame 10 and / or temple 30, so that the frame 10 and / or temple 30 can protect the battery module 40. In another example, the battery module 40 can be installed outside the frame 10 and / or temple 30. For example, after assembling the frame 10 and / or temple 30 into a closed structure, the battery module 40 is installed on the outer surface of the frame 10 and / or temple 30 by means of threaded connection, etc., thereby facilitating the replacement of the battery module 40. In other embodiments, when there are multiple battery modules 40, the battery modules 40 can be installed both inside and outside the frame 10 and / or temple 30, without limitation.

[0031] Please combine Figure 1 and Figure 4The first charging receiver 50 may include a first receiving coil 51 and a second electronic device 53. The second electronic device 53 may include four MOSFETs and a second capacitor C2. The four MOSFETs are designated as MOSFET 5, MOSFET 6, MOSFET 7, and MOSFET 8. MOSFETs 5 and 7 are connected in series and connected to one end of the second capacitor C2 via the first receiving coil 51. MOSFETs 6 and 8 are connected in series and connected to the other end of the first receiving coil 51. The series-connected MOSFETs 5 and 7, along with the series-connected MOSFETs 6 and 8, are connected in parallel to form a full-bridge inverter circuit. The schematic diagram of the wireless charging circuit of the first charging receiver 50 is shown below. Figure 4 As shown in the right-middle figure, the first receiving coil 51 can cooperate with the wireless charging transmitting coil 2031. The first receiving coil 51 can couple the electrical energy emitted by the wireless charging transmitting coil 2031. The second capacitor C2 and the first receiving coil 51 form a resonant circuit to improve the efficiency of the wireless charging system. The electrical energy coupled from the first receiving coil 51 is converted into DC power by a full-bridge rectifier circuit composed of MOSFETs 5, 6, 7 and 8 to charge the battery module 40.

[0032] Please see Figure 1 and Figure 5 The first receiving coil 51 may include two, each first receiving coil 51 being arranged around the mirror frame 10, and the two first receiving coils 51 being connected in series. Of course, the number of first receiving coils 51 may also be other, such as one, three, etc., and is not limited here.

[0033] The first receiving coil 51 includes, but is not limited to, a ferrite coil, an iron-core coil, or a copper-core coil. In this embodiment, the first receiving coil 51 is embedded within the frame 10.

[0034] Please combine Figure 2 When the frame 100 is placed in the charging base 200 in a folded state, the direction of the axis oo1 of the first receiving coil 51 is basically consistent with the direction of the magnetic lines 205, and the magnetic lines 205 pass through the two first receiving coils 51 to generate an induced current.

[0035] The plane of the first receiving coil 51 is approximately perpendicular to the magnetic field lines 205 in the magnetic field. The axis oo1 of the first receiving coil 51 is basically parallel to the magnetic field lines 205, generating an induced current. This ensures that when the frame 100 is placed on the base body 201 in a folded state, the battery module 40 can be wirelessly charged. Furthermore, the way the first receiving coil 51 and the wireless charging transmitting coil 2031 work together does not require any special requirements on the shape of the charging base 200. The magnetic field lines 205 generated by the wireless charging transmitting end 2031 pass through the two first receiving coils 51, thereby inducing a current, which then charges the battery module 40 connected in series with the first receiving coil 51.

[0036] Please combine Figure 4 The second charging receiver 70 may include a second receiving coil 71 and a third electronic device 73, the third electronic device 73 being identical to the second electronic device 53. The wireless charging circuit of the second charging receiver 70 is similar to... Figure 4 The structure shown in the middle right figure is the same, so it will not be described again here.

[0037] Please combine Figure 6 The second receiving coil 71 can be installed inside the temple 30. The axis oo2 of the second receiving coil 71 intersects the straight line oo3 in the extension direction of the temple 30. When the frame 100 is placed in the charging base 200 in the unfolded state, the direction of the axis oo2 of the second receiving coil 71 is basically consistent with the direction of the magnetic lines 205. The magnetic lines 205 pass through the second receiving coil 71 and generate an induced current to wirelessly charge the battery module 40, realizing wireless charging of the smart glasses 1000 in the unfolded state.

[0038] Preferably, the axis oo2 of the second receiving coil 71 is perpendicular to the straight line oo3 in the extension direction of the temple 30, ensuring that when the frame 100 is in the unfolded state and placed on the wireless charging transmitter 203, the area of ​​the magnetic field line 205 passing through the second receiving coil 71 in the magnetic field generated by the wireless charging transmitter 203 is as large as possible, increasing the magnetic flux and making the wireless charging of the battery module 40 more efficient.

[0039] In some embodiments, when the frame 100 is placed on the charging base 200 in a folded or unfolded state, the axis oo1 of the first receiving coil 51 intersects with the axis oo2 of the second receiving coil 71, so as to ensure that the battery module 40 can be wirelessly charged on the charging base 200 in both the folded and unfolded states, making the wireless charging form of the smart glasses 1000 more flexible and with a higher degree of freedom.

[0040] Preferably, when the frame 100 is placed on the charging base 200 in either a folded or unfolded state, the axis oo1 of the first receiving coil 51 and the axis oo2 of the second receiving coil 71 are perpendicular to each other. The frame 100 of this application, by providing two types of first and second receiving coils with their axes perpendicular to each other in space, allows the wireless charging transmitter 203 to engage with the first receiving coil 51 when the frame 100 is folded, and with the second receiving coil 71 when the frame 100 is unfolded. This enables wireless charging of the smart glasses 1000 in different placement configurations, making the wireless charging of the smart glasses 1000 more flexible and offering greater freedom of movement.

[0041] Please combine Figure 2 When the frame 100 is folded and placed on the charging base 200, the direction of the axis oo1 of the first receiving coil 51 is basically consistent with the direction of the magnetic field line 205, and the axis oo2 of the second receiving coil 71 is perpendicular to the magnetic field line 205. At this time, the second receiving coil 71 is approximately parallel to the magnetic field line 205 in the magnetic field, and the magnetic field line 205 passes perpendicularly through the two first receiving coils 51 installed inside the frame 10. The area through which the magnetic field line 205 passes through the first receiving coil 51 is the largest, and the magnetic flux is the largest. The first receiving coil 51 generates an induced current to charge the battery module 40.

[0042] Please see Figure 1 When the frame 100 is placed in the unfolded state on the charging base 200, the direction of the axis oo2 of the second receiving coil 71 is basically consistent with the direction of the magnetic field lines 205, and the axis oo1 of the first receiving coil 51 is perpendicular to the magnetic field lines 205. At this time, the first receiving coil 51 is approximately parallel to the magnetic field lines 205 in the magnetic field, while the magnetic field lines 205 pass perpendicularly through the second receiving coil 71 installed inside the temple 30. The area through which the magnetic field lines 205 pass through the second receiving coil 71 is the largest, and the magnetic flux is the largest. The induced current generated by the second receiving coil 71 charges the battery module 40.

[0043] Please see Figure 1 and Figure 3 In some embodiments, the frame 100 may further include a connecting shaft 60 and an electrical connector 80. The temple 30 is rotatably connected to the frame 10 via the connecting shaft 60. The first charging receiver 50 is electrically connected to the second charging receiver 70 via the electrical connector 80, and the electrical connector 80 can deform when the temple 30 rotates relative to the frame 10.

[0044] Specifically, the connecting shaft 60 is located between the frame 10 and the temple 30. The electrical connector 80 may include a flexible PCB. The connecting shaft 60 is connected by wiring using the electrical connector 80, and the electrical connector 80 is bendable, which can meet the electrical connection and communication between the temple 30 and the frame 10 when the frame 100 is in different states. This ensures that when the frame 100 is in the unfolded state and is wirelessly charged by the second charging receiver 70, the induced current generated by the second receiving coil 71 can be transmitted to the battery module 40 through the electrical connector 80; or, when the frame 100 is in the folded state and is wirelessly charged by the first charging receiver 50, the induced current generated by the first receiving coil 51 can also be transmitted to the battery module 40 through the electrical connector 80.

[0045] In some embodiments, the temple 30 can be detachably connected to the frame 10 to facilitate the replacement of different temples 30 to meet different needs.

[0046] Please see Figure 7 and Figure 8 Specifically, the frame 10 includes a first end 11 connected to the temple 30, and the temple 30 includes a second end 31 connected to the frame 10. The first end 11 is detachably connected to the second end 31 via a connecting shaft 60. Alternatively, one of the first end 11 and the second end 31 may be provided with a first magnetic 21, and the other with a second magnetic 23, and the first magnetic 21 and the second magnetic 23 may be detachably connected by magnetic attraction.

[0047] In some embodiments, the first end 11 is provided with a first charging terminal 111, which is electrically connected to a conductive terminal (not shown) of the charging base 200 to charge the battery module 40. At this time, the battery module 40 is installed in the frame 10, and the temple 30 is detached from its connection with the frame 10 so that the first charging terminal 111 is electrically connected to the conductive terminal to charge the battery module 40 installed in the frame 10.

[0048] In some embodiments, the second end 31 is provided with a second charging terminal 311, which is electrically connected to a conductive terminal to charge the battery module 40. In this case, the battery module 40 is installed in the temple 30, and the frame 10 is detached from its connection to the temple 30 frame to allow the second charging terminal 311 to be electrically connected to the conductive terminal, thereby charging the battery module 40 installed in the temple 30.

[0049] Please see Figure 7 This application also provides a smart glasses 1000. The smart glasses 1000 includes a lens 300 and a frame 100 according to any of the above embodiments, with the lens 300 mounted on the frame 10 of the frame 100.

[0050] Specifically, the lens 300 includes a display unit (not shown) for displaying virtual images. When the frame 100 is fully extended, the smart glasses 1000 can be worn normally on the user's head, allowing the user to see the projected virtual images in the display unit of the lens 300. This provides virtual information to the user while they view the real world, enhancing reality and achieving a virtual interactive effect.

[0051] Please combine Figure 1 In some embodiments, the two first receiving coils 51 of the first charging receiver 50 can also be installed in the lens 300. The first receiving coils 51 can also be electrically connected to the display unit. When the magnetic lines of force 205 generated by the wireless charging transmitter 203 pass through the first receiving coils 51, they can supply power to the display unit and charge the battery module 40.

[0052] The smart glasses 1000 of this application, by setting a first charging receiver 50 at the frame 10, when the frame 100 is placed in a folded state on the charging base 200, the magnetic lines of force 205 generated by the wireless charging transmitter 203 of the charging base 200 pass through the first charging receiver 50 to generate an induced current to charge the battery module 40. The smart glasses 1000 also installs a second charging receiver 70 at the temple 30, when the frame 100 is placed in an unfolded state on the charging base 200, the magnetic lines of force 205 generated by the wireless charging transmitter 203 pass through the second charging receiver 70 to generate an induced current to charge the battery module 40. The smart glasses 1000 of this application sets up two types of first charging receivers 50 and second charging receivers 70 in different positions, so that the wireless charging transmitter 203 can cooperate with the first charging receivers 50 and second charging receivers 70 when the frame 100 is in a folded or unfolded state, so as to realize wireless charging of the smart glasses 1000 in different placement forms. The form of wireless charging of the smart glasses 1000 is more flexible and has a higher degree of freedom.
