[0025] It should be noted that, with the rapid development of smart wearable devices, virtual reality (VR) devices have gradually become important tools in people's daily life and work. In order to improve the characteristics of VR glasses in portability, maintenance convenience and personalized customization, there are currently glasses leg separated VR glasses, which can set part of the load (such as speakers, etc.) on the glasses leg 2. When the user needs to use it, the glasses leg 2 is connected with the head-mounted device to form the VR glasses, and the load on the glasses leg 2 is powered by the head-mounted device.

[0026] However, the existing head-mounted device and glasses leg 2 are directly powered after being connected, and when the connection is unstable, direct power-on may cause damage to the circuit on the glasses leg 2, thereby affecting the service life.

[0027] In order to solve the above technical problems, the embodiment provides an intelligent glasses, in the embodiment, a power supply module 11 and a processing module 12 can be arranged in the head-mounted body 1, an identification module 21 and a target load 22 can be arranged in the leg 2, when the head-mounted body 1 is connected with the leg 2 in actual use, the processing module 12 can be connected with the identification module 21, the processing module 12 can transmit the generated handshake signal to the identification module 21, the identification module 21 can perform handshake identification according to the handshake signal, and feed back the response signal to the processing module 12 when the handshake identification is successful, and the processing module 12 can output the power supply signal to the power supply module 11 when the response signal is received, and the power supply module 11 supplies power to the target load 22 after receiving the power supply signal. Because in the embodiment, only when the processing module 12 and the identification module 21 perform handshake identification successfully, the power supply module 11 of the head-mounted body 1 is allowed to supply power to the target load 22 in the leg 2. Compared with the existing power-on after the head-mounted body 1 is connected with the leg 2, the embodiment can perform handshake identification after connection, and then power-on after handshake identification is successful, so as to ensure that power is supplied only after stable connection, and the service life is improved.

[0028] For the sake of understanding, the following will be combined with Figures 1 to 2 The intelligent glasses provided by the embodiment of the application will be specifically introduced.

[0029] Referring to Figure 1 , Figure 1 The structure block diagram of the first embodiment of the intelligent glasses provided by the embodiment of the application is shown.

[0030] As Figure 1 shown, in the embodiment, the intelligent glasses include a head-mounted body 1 and a leg 2, and the head-mounted body 1 is detachably connected with the leg 2.

[0031] It should be noted that the intelligent glasses in the embodiment can be VR glasses and the like, and the intelligent glasses in the embodiment can be a leg-separated VR glasses. Specifically, the intelligent glasses in the embodiment can include a head-mounted body 1 and a leg 2; wherein the head-mounted body 1 can be a component in the intelligent glasses for completing the display function and supplying power to the load in the leg 2, which can be provided with a display screen, a battery and the like, which can be set according to actual conditions, and the embodiment does not limit this; the leg can be a leg of any structure, and the leg 2 in the embodiment can be provided with a target load 22 for realizing part of the function of the VR glasses, such as a loudspeaker, which can be set according to actual conditions, and the embodiment does not limit this.

[0032] It should also be noted that the temple 2 in this embodiment may include a left temple and a right temple. It should be noted that the specific structure and internal components of the left temple in this embodiment may be consistent with those of the right temple. Therefore, in this embodiment and subsequent embodiments, only one side of the temple (for example, the left temple) is used for description. The specific right temple can refer to the left temple, and this embodiment will not go into details.

[0033] It can be understood that in this embodiment, the above-mentioned temples 2 can be detachably electrically connected to the head display body 1. For example, a male connector can be provided on the temples 2, and a female connector can be provided on the head display body 1. When the user needs to use it, the male connector on the temples 2 can be inserted into the female connector on the head display body 1, and can be pulled out when it is not needed, thereby realizing a detachable connection.

[0034] It is also understandable that in this embodiment, the temples 2 and the head display body 1 can be detachably connected by other means, and this embodiment does not limit this.

[0035] In this embodiment, in order to ensure that the connection is stable before power is supplied, Figure 1 As shown, the head display body 1 includes: a power supply module 11 and a processing module 12; the temple 2 includes: an identification module 21 and a target load 22; the processing module 12 is connected to the power supply module 11 and the identification module 21 respectively, and the power supply module 11 is also connected to the target load 22; The processing module 12 is configured to, when connected to the identification module 21, transmit the generated handshake signal to the identification module 21 and determine whether a response signal fed back by the identification module 21 is received, the response signal being generated by the identification module 21 after successful handshake recognition of the handshake signal; The processing module 12 is further configured to output a power supply signal to the power supply module 11 upon receiving the response signal, so that the power supply module 11 supplies power to the target load 22 .

[0036] It should be understood that the power supply module 11 can be any module that provides operating power to the target load 22. Since VR glasses are generally equipped with batteries, the power supply module 11 can be a battery module 111, etc., and this embodiment is not limited to this. The target load 22 can be any power-consuming load on the VR glasses, such as a speaker or temperature sensor. This embodiment uses a speaker for illustration, but is not limited to this.

[0037] It should also be understood that the above processing module 12 and the identification module 21 can be any device with program running function, such as a microcontroller unit (MCU), and the specific setting can be made by itself according to the actual situation, which is not limited in the embodiment.

[0038] It should be noted that the above handshake signal can be a signal for handshake interaction, for example, it can be a group of square waves, and of course it can also be other waves, which are not limited in the embodiment. In the embodiment, the processing module 12 can generate the handshake signal at a predetermined time interval. In actual use, when the user does not connect the temple 2 and the head-mounted body 1, the processing module 12 has no handshake signal transmission to the identification module 21. When the user inserts the temple 2 into the head-mounted body 1, the loop between the processing module 12 and the identification module 21 is conducted, and then the processing module 12 can transmit the generated handshake signal to the identification module 21.

[0039] After receiving the handshake signal, the identification module 21 can perform handshake identification according to the handshake signal, which can be to identify whether the model information of the head-mounted device matches, and of course it can also identify other contents, which are not limited in the embodiment. After the temple 2 and the head-mounted body 1 are successfully matched, the identification module 21 can determine that the handshake identification is successful, and generate the above response signal feedback to the processing module 12. The response signal can be any signal for indicating that the handshake identification is successful, or a group of square waves.

[0040] After receiving the response signal, the processing module 12 can start outputting the power supply signal to the power supply module 11, which can be any signal allowing the power supply module 11 to supply power. After receiving the power supply signal, the power supply module 11 can indicate that the connection between the head-mounted body 1 and the temple 2 is stable, and then output the power supply current to the target load 22 on the temple 2 to supply power to the target load 22.

[0041] Therefore, in the embodiment, only when the processing module 12 and the identification module 21 successfully perform handshake identification, the power supply module 11 of the head-mounted body 1 is allowed to supply power to the target load 22 in the temple 2. Compared with the existing direct power-on after the connection of the head-mounted body 1 and the temple 2, the embodiment can first perform handshake identification after the connection, and then perform power-on after the successful handshake identification, so as to ensure that the power supply is performed after the connection is stable, thereby improving the service life.

[0042] It should be emphasized that considering that there is generally no power supply device on the temple 2, in the embodiment, when the temple 2 is inserted into the head-mounted body 1, the identification module 21 can also be electrically connected with the power supply module 11 to supply power to the identification module 21.

[0043] Further, when the temple 2 is inserted into the head-mounted body 1, the power supply module 11 can first provide working current to the identification module 21, so that the identification module 21 is powered on to start receiving the handshake signal.

[0044] Further, in order to perform handshake identification on the handshake signal, in the embodiment, the identification module 21 is configured to compare the handshake signal with a preset signal when the handshake signal is received. The identification module 21 is further configured to determine that the handshake identification is successful when the handshake signal matches the preset signal, and transmit a generated response signal to the processing module 12.

[0045] It should be noted that the above-mentioned preset signal can be a signal for indicating that the temple 2 matches the head-mounted body 1. Since the above-mentioned handshake signal in the embodiment can be a square wave, different head-mounted bodies 1 can generate square waves with different parameters, such as different amplitudes or different time intervals, which are not limited in the embodiment.

[0046] In actual use, the processing module 12 can generate a handshake signal corresponding to the amplitude and time interval and transmit it to the identification module 21 of the temple 2. The identification module 21 can determine whether the amplitude and time interval of the handshake signal are consistent with the pre-stored preset signal. If not, it means that the handshake identification fails, and the identification module 21 does not generate a response signal, and the head-mounted body 1 does not perform power supply; if yes, it means that the handshake identification is successful, and the identification module 21 generates a response signal to the processing module 12.

[0047] Further, in order to improve safety, as shown in Figure 1 In the embodiment, the temple 2 further comprises a switch module 23. The switch module 23 is connected with the power supply module 11, the identification module 21 and the target load 22 respectively. The identification module 21 is further configured to output a conduction signal to the switch module 23 when the handshake identification on the handshake signal is successful. The switch module 23 is configured to turn on a loop between the power supply module 11 and the target load 22 when the conduction signal is received, so that the power supply module 11 supplies power to the target load 22.

[0048] It can be understood that the above-mentioned switch module 23 can be any module with on-off switching function, such as a switch tube, which is not limited in the embodiment.

[0049] As shown in Figure 1As shown, the switch module 23 in this embodiment can be arranged on the loop between the target load 22 and the power supply module 11, and the control end of the switch module 23 can be connected with the identification module 21.

[0050] Further, in actual use, when the switch module 23 does not receive the conduction signal, the loop between the target load 22 and the power supply module 11 is disconnected. After the identification module 21 successfully identifies the handshake signal, it can generate a conduction signal allowing power supply and transmit it to the switch module 23. After receiving the conduction signal, the switch module 23 turns on the power supply loop between the power supply module 11 and the target load 22, so that the power supply module 11 transmits the generated power supply current to the target load 22 through the switch module 23.

[0051] Further, considering that the power supply current can be large at the moment when the loop between the power supply module 11 and the target load 22 is turned on, which can cause the components to be easily damaged, in this embodiment, the switch module 23 is arranged between the power supply module 11 and the target load 22, and the switch module 23 is controlled by the identification module 21. Figure 1 As shown, the glasses leg 2 further comprises an overcurrent detection module 24. The overcurrent detection module 24 is connected with the power supply module 11 and the target load 22 respectively. The overcurrent detection module 24 is configured to determine whether overcurrent occurs in the power supply current output by the power supply module 11. The overcurrent detection module 24 is further configured to transmit the power supply current to the target load 22 for power supply when the overcurrent does not occur in the power supply current.

[0052] It should be noted that the overcurrent detection module 24 can be any module with overcurrent detection function. The power supply current can be the current provided to the target load 22 for power supply.

[0053] In actual use, the overcurrent detection module 24 can be arranged on the power supply loop between the target load 22 and the power supply module 11, specifically, if the switch module 23 is arranged, it can be arranged between the switch module 23 and the power supply module 11. Further, when the switch module 23 turns on the power supply loop between the target load 22 and the power supply module 11, the power supply module 11 can output the power supply current to the overcurrent detection module 24. The overcurrent detection module 24 can collect and determine the current value of the power supply current in real time, and compare it with the preset current threshold. When it is not higher than the preset current threshold, it can be determined that overcurrent does not occur, and then the overcurrent detection module 24 transmits the power supply current to the switch module 23, which is then transmitted to the target load 22; when it is higher than the preset current threshold, it can be determined that overcurrent occurs, and then the overcurrent detection module 24 prohibits the transmission of the power supply current to the working module, and the target load 22 does not work. Thus, overcurrent protection is achieved.

[0054] Further, considering that the speaker can be arranged on the glasses leg 2, in order to make the speaker play the audio of the head-mounted body 1, it is continued as shown in the figure Figure 1 In the embodiment, the target load 22 includes an audio playing module (not shown in the figure); The audio playing module is further connected with the processing module 12; The processing module 12 is further used for transmitting the generated audio signal to the audio playing module; The audio playing module is used for playing audio according to the received audio signal in the case that the power supply module 11 supplies power.

[0055] It should be noted that the above-mentioned audio playing module can be any module for playing audio, such as a speaker, and the embodiment does not limit this. Figure 1 In the figure, the target load 22 can be directly replaced by the above-mentioned audio playing module, and the specific connection relationship is not described here.

[0056] It should be emphasized that the audio playing module can also be connected with the processing module 12 in the embodiment. Further, in actual use, when the audio playing module is in the power-on working state, if the processing module 12 needs to play audio, the processing module 12 can directly transmit the generated audio signal to the audio playing module, and the audio playing module can play audio according to the audio signal.

[0057] In the embodiment, the power supply module 11 and the processing module 12 can be arranged in the head-mounted body 1, and the identification module 21 and the target load 22 can be arranged in the glasses leg 2. In actual use, when the head-mounted body 1 is connected with the glasses leg 2, the processing module 12 can be connected with the identification module 21, the processing module 12 can transmit the generated handshake signal to the identification module 21, the identification module 21 can perform handshake identification according to the handshake signal, and feed back the response signal to the processing module 12 when the handshake identification is successful, and the processing module 12 can output the power supply signal to the power supply module 11 when the response signal is received, and the power supply module 11 supplies power to the target load 22 after receiving the power supply signal. In the embodiment, only when the processing module 12 and the identification module 21 perform handshake identification successfully, the power supply module 11 of the head-mounted body 1 is allowed to supply power to the target load 22 in the glasses leg 2. Compared with the existing direct power-on after the connection of the head-mounted body 1 and the glasses leg 2, the embodiment can first perform handshake identification after the connection, and then perform power-on after the handshake identification is successful, so as to ensure that the power supply is performed after the connection is stable, and the service life is improved.

[0058] Referring to Figure 1 , Figure 2 The circuit principle diagram of the second embodiment of the intelligent glasses proposed in the embodiment.

[0059] Based on the first embodiment, a second embodiment of the smart glasses of the present application is provided, as shown in Figure 2 In this embodiment, in order to realize the handshake recognition, the processing module 12 comprises a processor 121. The power supply end of the processor 121 (i.e. Figure 2 VDD_MAIN of the processor 121) can be connected with the power supply module 11, the first communication end of the processor 121 (i.e. Figure 2 TX of the processor 121) and the second communication end of the processor 121 (i.e. Figure 2 RX of the processor 121) are connected with the identification module 21, the first audio playing end of the processor 121 (i.e. Figure 2 DP of the processor 121) and the second audio playing end of the processor 121 (i.e. Figure 2 DN of the processor 121) are all connected with the audio playing module 25, the grounding end of the processor 121 (i.e. Figure 2 GND of the processor 121) is connected with the reference ground of the head-mounted body 1 and the reference ground of the temple 2, and the control end of the processor 121 (i.e. Figure 2 IO of the processor 121) can also be connected with the power supply module 11.

[0060] It should be noted that the above-mentioned processor 121 can be any device that realizes the above-mentioned functions, and the specific model can be set according to the actual situation, and the present embodiment does not limit this.

[0061] In actual use, under the power supply of the power supply module 11, the processor 121 can generate handshake signals at regular time intervals. After receiving the response signal, the control end of the processor 121 outputs a power supply signal to the power supply module 11.

[0062] Further, in order to realize the handshake recognition, as shown in Figure 2 In this embodiment, the identification module 21 comprises a handshake recognition chip U1, a first capacitor C1 and a first diode D1. The power supply end of the handshake recognition chip U1 is connected with the first end of the first capacitor C1 and the cathode of the first diode D1, the anode of the first diode D1 is connected with the power supply module 11, the second end of the first capacitor C1 is grounded, the first communication end of the handshake recognition chip U1 and the second communication end of the handshake recognition chip U1 are both connected with the processing module 12, and the grounding end of the handshake recognition chip U1 is grounded.

[0063] It should be noted that the above-mentioned handshake recognition chip U1 can be any chip with handshake recognition function, such as a microcontroller, and the present embodiment does not limit this.

[0064] It can be understood that the power supply end of the hand recognition chip U1 (i.e. Figure 2 VDD of the hand recognition chip U1) in the embodiment can be connected with the power supply module 11 (i.e. Figure 2 VCC2) through the first diode D1 to receive the working current provided by the power supply module 11 for power-on working, and the first diode D1 can play a protection role and the first capacitor C1 can play a filtering role.

[0065] It can also be understood that the first communication end of the hand recognition chip U1 (i.e. Figure 2 RX of the hand recognition chip U1) can be connected with the first communication end of the processor 121 for receiving the hand signal. The second communication end of the hand recognition chip U1 (i.e. Figure 2 TX of the hand recognition chip U1) can be connected with the second communication end of the processor 121 for feeding back the response signal.

[0066] In actual use, after the first communication end of the hand recognition chip U1 receives the hand signal, the hand recognition chip U1 can perform recognition and output the response signal through the second communication end of the hand recognition chip after the hand recognition is successful.

[0067] Further, in order to realize the switching function, in the embodiment, the switching module 23 includes a switching chip U2, a first resistor R1 and a second capacitor C2.

The power management unit 112 is configured to adjust the power supply current provided by the battery module 111 according to the received power supply signal, and transmit the adjusted power supply current to the target load 22 for power supply.

[0078] It should be noted that the above-mentioned battery module 111 can be any module with power supply function, such as a battery pack, and the present embodiment does not limit it. In the present embodiment, the battery module 111 can further include a battery protection board, which can be used for overcharge, overdischarge, overcurrent and short circuit protection of the battery pack, to ensure safe and stable operation of the battery and prolong the service life of the battery.

The processing module 12 can extract the power supply information from the response signal and generate a corresponding power supply signal according to the power supply information and transmit the power supply signal to the power management unit 112. The power management unit 112 can adjust the power supply current output by the battery module 111 according to the corresponding power supply signal, which can be voltage adjustment, current adjustment, etc., to meet the power supply current required by the target load 22.
