[0020] The following will be combined with the accompanying drawings to describe in detail a wearable device, a working method thereof, and a specific implementation of a split-type extended reality device provided by an embodiment of the present invention. It should be noted that the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0021] The embodiment of the present invention provides a wearable device for use in an extended reality device, such as Figure 1 As shown, it includes: a wearing frame 100, a first power supply unit 200, a SOC motherboard 300 and a keyboard unit 400 are provided in the wearing frame 100, and the first power supply unit 200 is electrically connected to the SOC motherboard 3000;

[0022] The keyboard unit 400 includes a plurality of keys ( Figure 1 (not shown), the keyboard unit 400 is used to: establish a wireless connection with the SOC mainboard 300 in response to being separated from the wearing frame 100.

[0023] In this way, by providing a keyboard unit with multiple keys in the wearable device and achieving a wireless connection between the keyboard unit and the SOC motherboard when the keyboard unit is separated from the wearable frame, character input can be achieved through the multiple keys on the keyboard unit, improving the efficiency of character input. Moreover, using a physical keyboard for character input allows character input through the tactile sense of the fingers when the wearer is unable to observe the outside world, facilitating blind typing of characters. In addition, when character input is not in progress, the keyboard unit can be combined with the wearable frame, achieving the integration of the wearable device and further improving the portability of the extended reality device.

[0024] It should be understood that extended reality is a general term for VR (Virtual Reality), AR (Augmented Reality) and MR (Mixed Reality). In order to reduce the burden on the user's head, the display device in the extended reality device can be separated from other parts such as the power supply and processor. The wearable device is the part of the extended reality device that is separated from the display device. The portability of the extended reality device is improved by wearing it. For example, the user can hang the wearable device around the neck. Of course, the wearable device can also be worn at the waist and other positions, which is not specifically limited here.

[0025] Optionally, the keys in the keyboard unit may include character keys and function keys, wherein the character keys are used to input various characters such as numbers, letters, and symbols, and the function keys are used to perform various functions such as deletion, confirmation, line break, and cursor movement. In this way, by using multiple keys with different functions, it is possible to input various characters and perform various operations on characters, thereby meeting the character input requirements of the extended reality device in various scenarios.

[0026] Specifically, if Figure 2 As shown, Figure 2 This is a schematic diagram of the key arrangement on a keyboard unit, where the keyboard unit includes a first area Q1 for setting character keys and a second area Q2 for setting function keys. The first area Q1 is provided with 13 character keys, namely key 1 to key 12, and each character key can be arranged in an array of four rows and three columns. The characters corresponding to each key can be, but are not limited to, set in the same way as the character setting of the commonly used pinyin 9 keys. For example, key 1 corresponds to "number 1", key 2 corresponds to the number "2" and the letters "ABC", key 3 corresponds to the number "3" and the letters "DEF", ..., key 10 corresponds to the symbol "*", key 11 corresponds to the number "0" and the symbol "space", and key 12 corresponds to the symbol "#", which conforms to the user's daily usage habits, reduces the key selection time while meeting the input accuracy, thereby improving the efficiency of character input, and each character key can be located within the motion range of the thumb of one hand, so that the user can use the keyboard unit with one thumb to complete character input, thereby improving the convenience of character input.

[0027] Of course, at least some of the character keys can also correspond to other symbols, such as "!", "?", "-", "," etc., which are not specifically limited here.

[0028] Continue to see Figure 2 , the second area Q2 is provided with 9 function keys from key 13 to key 21, and the functions corresponding to each key can be but are not limited to: keys 13 to key 16 correspond to "function selection", "voice", "delete", and "line break" respectively; keys 17 to key 20 correspond to the four function keys of "up", "down", "left", and "right" for controlling the movement direction of the cursor respectively; key 21 corresponds to the "confirm" key. In this way, various functions such as recording, voice control, and picture insertion can be quickly realized through each function key, which can meet the document editing needs of instant chatting, email processing, and other business travel and office scenarios, thereby improving the application scope of extended reality devices.

[0029] Furthermore, when using the keyboard unit to input characters, the character input interface can be synchronously displayed in the display device. When pressing the keys on the keyboard unit, corresponding feedback appears on the character input interface, so that the user can intuitively see his or her operation when his or her fingers touch the keys, so that character input takes into account touch, vision and convenience at the same time.

[0030] Alternatively, as Figure 3 As shown, the first power supply unit 200 includes: a first power supply 201, a charge and discharge management circuit 202 electrically connected to the first power supply 201, and a charging interface 203 electrically connected to the charge and discharge management circuit 202. The SOC mainboard 300 is electrically connected to the charge and discharge management circuit 202. The charge and discharge management circuit 202 can be a circuit that is well known to those skilled in the art and can implement charge and discharge management, and is not specifically limited here.

[0031] In this way, under the control of the charge and discharge management circuit, the first power supply can be charged through the charging interface, and the first power supply can be powered to the SOC mainboard, so that the SOC mainboard can control the display device connected thereto to display content.

[0032] Optionally, the first power source can be configured as a detachable structure, so that when the power of one of the first power sources is exhausted, the exhausted first power source can be removed from the wearable frame and the first power source with stored power can be installed in the wearable frame, eliminating the need to wait for the charging process, thereby improving the continuity of the user experience. In addition, the charging interface can be removed to simplify the structure of the wearable device, or the charging interface can be retained to improve the convenience of charging.

[0033] Alternatively, as Figure 3 As shown, the keyboard unit 400 is reused as the second power supply unit 500, and the second power supply unit 500 includes a second power supply 401, a wearable frame ( Figure 3 (not shown) includes a handle interface 101, and the second power supply 401 is electrically connected to the charge and discharge management circuit 202 through the handle interface 101.

[0034] By reusing the keyboard unit as a second power supply, the second power source in the keyboard unit can serve as a backup power source for the SOC motherboard when the keyboard unit is attached to the wearable frame, increasing the wearable device's battery capacity and extending the battery life of the extended reality device. Furthermore, when the keyboard unit is attached to the wearable frame, the second power source can be charged through the charging port, making charging the keyboard unit more convenient.

[0035] Furthermore, the second power supply and the handle interface can be electrically connected by, but not limited to, a magnetic PIN (Charging Pin), and the magnetic PIN can also achieve a fixed connection between the keyboard unit and the wearable frame, so that the user can easily and quickly remove the keyboard unit from the wearable frame or install the keyboard unit on the wearable frame, thereby improving the ease of use of the wearable device.

[0036] Alternatively, as Figure 4 As shown, the charge and discharge management circuit includes: a charging circuit 2021, a power supply circuit 2022, a first fuel meter 2023 and a second fuel meter 2024; the charging circuit 2021 is electrically connected to the charging interface 203, the first power supply 201 and the second power supply 401 respectively, the power supply circuit 2022 is electrically connected to the first power supply 201, the second power supply 401 and the SOC mainboard 300 respectively, the first fuel meter 2023 is electrically connected to the first power supply 201 and the SOC mainboard 300 respectively, and the second fuel meter 2024 is electrically connected to the second power supply 401 and the SOC mainboard 300 respectively.

[0037] The first fuel gauge 2023 is used to monitor the power level of the first power supply 201 and transmit the power level of the first power supply 201 to the SOC mainboard 300. The second fuel gauge 2024 is used to monitor the power level of the second power supply 401 and transmit the power level of the second power supply 401 to the SOC mainboard 300. The first fuel gauge 2023 and the SOC mainboard 300, as well as the second fuel gauge 2024 and the SOC mainboard 300, can be electrically connected using an I2C (Inter-Integrated Circuit) bus. In addition, two lines may be included between the power supply circuit 2022 and the SOC mainboard 300, one of which is used for the power supply circuit 2022 to supply power to the SOC mainboard 300, and the other is used for the SOC mainboard 300 to control the power supply line 2022, thereby achieving control over the power supply of the dual power supplies (the first power supply 201 and the second power supply 401).

[0038] Optionally, when the power level of the first power supply 201 is greater than or equal to a first threshold, the first power supply 201 charges the second power supply 401 through the power supply circuit 2022; when the power level of the first power supply 201 is less than a second threshold, the second power supply 401 supplies power to the SOC mainboard 300 through the power supply circuit 2022; wherein the first threshold is greater than the second threshold.

[0039] Among them, the working principle of the power supply management circuit may include: when the charging interface 203 is connected to an external power supply, the charging circuit 2021 charges the first power supply 201 and the second power supply 401; the power supply circuit 2022 uses the first power supply 201SOC motherboard 300 for power supply by default. When the charging interface 203 is not connected to an external power supply, the first power supply 201 can power the second power supply 401 through the power supply circuit 2022 under preset conditions. The preset conditions may include: the voltage of the first power supply 201 is less than the voltage of the second power supply 401, and the power of the first power supply 201 is greater than or equal to a first threshold. The first threshold can be but is not limited to being set to 40%; when the power of the first power supply 201 is lower than the second threshold, the power supply circuit 2022 uses the second power supply 401 to power the SOC motherboard 300 and reminds the user to charge. The second threshold can be but is not limited to being set to 10%.

[0040] Of course, the first threshold and the second threshold may also be set to other values, for example, the first threshold is set to 30% and the second threshold is set to 5%, which is not specifically limited here.

[0041] In this way, by setting up a charging circuit, a power supply circuit and two fuel meters, the charge and discharge management unit can power the SOC mainboard through the first power supply and the second power supply, and by setting the first threshold and the second threshold, dynamic adjustment of the power supply to the second power supply and the SOC mainboard is achieved, thereby improving the practicality of the wearable device.

[0042] It should be understood that since the second power supply is located in the keyboard unit, the second power supply is a hot-swappable design. When the keyboard unit is separated from the wearable frame for a period of time and then reconnected, the power level of the second power supply will change due to use. However, after the second power supply is electrically reconnected to the second fuel gauge, since the conventional fuel gauge strategy for measuring power includes an algorithm to prevent sudden changes in power level, the power level in the second fuel gauge still shows the previous power level and cannot be updated immediately. If the second power supply needs to be switched but the power level of the second power supply is insufficient, it may cause abnormal operation or even shutdown. Therefore, in order to prevent sudden changes in power level, it is necessary to implement a forced power reset function after the second power supply is electrically connected to the second fuel gauge. This function can be implemented through the kernel layer driver in the SOC motherboard.

[0043] The method of forcing the battery to reset includes but is not limited to the notifier mechanism program in the Linux kernel, namely, blocking notifier chains. The specific process of implementing the forced battery reset using the notifier mechanism program can be as follows: Figure 5 As shown, Figure 5The three dotted boxes represent the processes in the dual-power driver, notifier mechanism, and fuel gauge driver, respectively. By using the notifier API provided by the Linux kernel, the notifier registration function and notifier deregistration function are defined, and the notifier event notification function is defined. These functions serve as the entry point for other drivers to bind the notifier events of the dual-power driver. The notified registration function defined by the dual power is used in the fuel gauge driver to bind the notifier events of the dual-power driver. When the second power supply is reconnected, the dual-power driver triggers an interrupt and calls the notifier event notification function. At this time, since the fuel gauge driver has bound the notifier event of the dual power supply, the fuel gauge driver will immediately call the reset power thread to force the reset of the second fuel gauge, thereby updating the power of the second power supply.

[0044] In this way, by performing a forced power reset, when it is determined in the dual power driver program that there is a plug-in event for the second power supply (a jump occurs in the ADC sampling of the second power supply voltage), the event is notified to the power meter driver program, thereby completing the forced reset of the second power meter in the power meter driver program, realizing the update of the second power supply power, and ensuring the normal operation of the wearable device.

[0045] Alternatively, as Figure 6 As shown, the keyboard unit 400 includes: a signal processing unit 403 electrically connected to each key 402, a wireless communication unit 404 electrically connected to the signal processing unit 403, a second power supply 401 and a switching circuit 405, the first end A of the switching circuit 405 is electrically connected to the second power supply 401, and the second end B of the switching circuit 405 is electrically connected to the signal processing unit 403 and the wireless communication unit 404, respectively.

[0046] Among them, the signal processing unit 403 can be but is not limited to a device with signal processing capabilities such as an MCU (Microcontroller Unit), each button 402 can be but is not limited to being electrically connected to the signal processing unit 403 through a GPIO (General Purpose Input / Output) pin on the signal processing unit 403, and the wireless communication unit can be but is not limited to being electrically connected to the signal processing unit through a UART (Universal Asynchronous Receiver / Transmitter).

[0047] In this way, after the keyboard unit is separated from the wearable frame, the key value signal is input into the signal processing unit by pressing each key, and then the signal processing unit encodes the key value signal and sends it to the wireless communication unit. After receiving the signal, the wireless communication unit converts it into a wireless signal and sends it to the SOC mainboard, thereby realizing the input of characters.

[0048] Optionally, when the time interval between two consecutive presses of the same key is less than a first preset time interval, only one key value is generated. The first preset time interval includes, but is not limited to, 10ms. Thus, by setting the first preset time interval, repeated input caused by jitter of the key shrapnel can be avoided, thereby improving the accuracy of character input.

[0049] Optionally, when no key input is detected within a second preset time interval, the keyboard unit enters a sleep state, and the keyboard unit can be awakened by pressing any or a specified key while in the sleep state. The second preset time interval includes, but is not limited to, 10 minutes. Thus, by setting the second preset time interval, the power consumption of the keyboard unit can be further reduced, thereby increasing the battery life of the keyboard unit and the wearable device.

[0050] Alternatively, as Figure 6 As shown, the wearing frame ( Figure 6 (not shown) includes a handle interface 101, and the switch circuit 405 includes a third terminal C electrically connected to the handle interface 101. The switch circuit 405 is used to: respond to a control signal input from the third terminal C to control the path between the first terminal A and the second terminal B to be disconnected.

[0051] In this way, by providing a third terminal of the switch circuit, the first terminal and the second terminal can be connected and disconnected, thereby controlling the activation and deactivation of the signal processing unit and the wireless communication unit within the keyboard unit. This can reduce energy consumption when the keyboard unit is not in use and increase the keyboard unit's battery life. In addition, when the keyboard unit is reused as a second power supply unit, the battery life of the wearable device can be further extended.

[0052] Alternatively, as Figure 6 As shown, the switching circuit 405 includes: a metal oxide semiconductor field effect transistor (i.e., a MOS tube) and a pull-up circuit, the control terminal c of the metal oxide semiconductor field effect transistor is electrically connected to the third terminal C and the output terminal of the pull-up circuit respectively, the input terminal a of the metal oxide semiconductor field effect transistor is electrically connected to the first terminal A, the output terminal b of the metal oxide semiconductor field effect transistor is electrically connected to the second terminal B, and the third terminal C is electrically connected to the ground terminal GND through the handle interface 101.

[0053] The pull-up circuit may include a first resistor R1, one end of the first resistor R1 being electrically connected to a control terminal c of a metal oxide semiconductor field effect transistor (hereinafter referred to as a MOS transistor), and the other end of the first resistor R1 being electrically connected to an input terminal of a first voltage V1. Thus, when the keyboard unit 400 is electrically connected to the handle interface 101, the control terminal c of the MOS transistor is electrically connected to the ground terminal GND. At this time, the voltage of the control terminal c of the MOS transistor is the ground voltage, which in turn controls the path between the input terminal a and the output terminal b of the MOS transistor to be disconnected, thereby turning off the signal processing unit 403 and the wireless communication unit 404 in the keyboard unit 400. When the keyboard unit 400 is electrically disconnected from the handle interface 101, the control terminal c of the MOS transistor is electrically connected to the ground terminal GND. At this time, the voltage of the control terminal c of the MOS transistor is the first voltage V1. Thus, the first voltage V1 controls the conduction between the input terminal a and the output terminal b of the MOS transistor, thereby turning on the signal processing unit 403 and the wireless communication unit 404 in the keyboard unit 400.

[0054] In this way, by providing a switch unit with a MOS tube and a pull-up circuit, the opening and closing of the signal processing unit and the wireless communication unit in the keyboard unit can be automatically controlled, thereby reducing the complexity of using the wearable device.

[0055] Of course, in addition to the use of MOS tubes and pull-up circuits as switches as mentioned above, switches of other structures familiar to those skilled in the art can also be used, such as but not limited to button switches. When using button switches, the user can press the button to control the opening and closing of the switch, or the opening and closing of the switch can be controlled by squeezing between the keyboard unit and the wearable frame. The specific setting form of the switch is not limited here.

[0056] Alternatively, as Figure 7 As shown, the SOC motherboard 300 and the keyboard unit 400 include a Bluetooth module 301. The Bluetooth module in the keyboard unit 400 is located in the wireless communication unit 404. Figure 7 Not shown in the figure.

[0057] In this way, by setting up a Bluetooth module in the SOC motherboard and the keyboard unit, a wireless connection between the keyboard unit and the SOC motherboard can be achieved, so that characters can be input by pressing keys on the keyboard unit, thereby improving the efficiency of character input when using the augmented reality device.

[0058] Furthermore, when the wireless communication unit and the SOC mainboard use a Bluetooth module for wireless communication, the Bluetooth module can, but is not limited to, operate in BLE (Bluetooth Low Energy) mode, thereby reducing the energy consumption of the wearable device and improving the battery life of the wearable device.

[0059] Alternatively, as Figure 7 As shown, the SOC motherboard also includes a core 302 electrically connected to the Bluetooth module 301. The core 302 and the Bluetooth module 301 can be electrically connected using I2C. The core 302 is configured with a HID (Human Interface Device) driver and a display driver, and the keyboard unit is registered as a HID device. The moving cursor for character input displayed on the display device is synchronously associated with the keyboard unit. Among them, the core 302 can be a system core well known to those skilled in the art, such as the Android kernel, etc., and is not specifically limited here.

[0060] In this way, by configuring the HID driver and display driver, after the keyboard unit establishes a wireless connection with the SOC motherboard, when a key in the keyboard unit is pressed, the SOC motherboard can receive and identify the key value of the corresponding key, thereby completing the corresponding character input and selection control operations, and can render and display the corresponding information on the display device according to the operation content.

[0061] Optionally, the wearable device also includes buttons for power on / off, volume control, and other functions. These buttons can be directly connected to the SOC motherboard. Alternatively, at least some of these buttons can be integrated into the keyboard unit, simplifying the structure of the wearable device. This allows for convenient and quick access to functions such as power on / off and volume control for the extended reality device.

[0062] The wearable device provided by the embodiment of the present invention is explained below with reference to specific embodiments.

[0063] like Figure 8 As shown, Figure 8 The schematic diagram of a neck-hanging wearable structure is shown. The wearable frame 100 can be worn on the user's neck. The two ends of the wearable frame 100 are the left part L and the right part R. The SOC motherboard ( Figure 8 The left side portion L is not shown in the figure, and the right side portion R includes a keyboard unit 400, a first power supply unit 200, and a partition 600, wherein the partition 600 is used to protect the first power supply unit 200, and prevent the first power supply unit 200 from being exposed to the outside after the keyboard unit 400 is taken out, thereby protecting the first power supply unit 200, and the partition 600 is provided with an opening for electrical connection between the keyboard unit 400 and the handle interface 101. In addition, the wearable frame is also provided with a connecting structure K, which is used to electrically connect the SOC motherboard and the display device in the wearable device.

[0064] During use, the user wears the wearable frame 100 around the neck. When there is no need to input characters, the keyboard unit 400 and the wearable frame 100 are combined into a whole, and the signal processing unit and the wireless communication unit in the keyboard unit 400 are turned off. The second power supply in the keyboard unit 400 serves as a backup power supply for the SOC mainboard, thereby improving the battery life of the wearable device; when character input is required, the user can remove the keyboard unit 400 from the wearable frame 100, and at the same time, the second power supply in the keyboard unit 400 is turned on to power the signal processing unit and the wireless communication unit, and the wireless communication unit establishes a wireless connection with the SOC mainboard in the wearable frame, so that when the user interacts with the keys on the keyboard unit 400, the key value signal corresponding to each key is input to the signal processing unit, and then the signal processing unit encodes the key value signal and sends it to the wireless communication unit. The wireless communication unit converts the received signal into a wireless signal and sends it to the SOC mainboard in the wearable frame 100, so that the SOC mainboard realizes character input according to the received wireless signal and controls the display device for display.

[0065] Based on the same inventive concept, an embodiment of the present invention also provides a working method of a wearable device. The implementation principle of the working method is similar to that of the aforementioned wearable device. The specific implementation method of the working method can be found in the embodiment of the aforementioned wearable device, and the repeated parts will not be repeated here.

[0066] Specifically, an embodiment of the present invention provides a working method of a wearable device as described above, such as Figure 9 As shown, it includes: S901, when the keyboard unit is separated from the wearing frame, the keyboard unit establishes a wireless connection with the SOC mainboard.

[0067] In this way, by providing a keyboard unit with multiple keys in the wearable device and achieving a wireless connection between the keyboard unit and the SOC motherboard when the keyboard unit is separated from the wearable frame, character input can be achieved through the multiple keys on the keyboard unit, improving the efficiency of character input. In addition, when character input is not in progress, the keyboard unit can be combined with the wearable frame, achieving the integration of the wearable device and further improving the portability of the extended reality device.

[0068] Alternatively, as Figure 9 As shown, the working method of the wearable device also includes: S902, when the keyboard unit is combined with the wearable frame, the keyboard unit is reused as a second power supply unit, and the second power supply in the second power supply unit is electrically connected to the SOC mainboard.

[0069] In this way, by reusing the keyboard unit as a second power supply unit, when the keyboard unit is combined with the wearable frame, the second power supply in the keyboard unit can be used as a backup power supply to power the SOC mainboard, thereby increasing the battery capacity of the wearable device and increasing the battery life of the extended reality device.

[0070] Based on the same inventive concept, an embodiment of the present invention also provides a split-type extended reality device. The implementation principle of the split-type extended reality device is similar to that of the aforementioned wearable device. The specific implementation method of the split-type extended reality device can be found in the embodiment of the aforementioned wearable device, and the repeated parts will not be repeated.

[0071] Specifically, an embodiment of the present invention provides a split-type extended reality device, such as Figure 10 As shown, it includes: a wearable device 1001 as introduced in the above content, and a display device 1002 electrically connected to the wearable device 1001.

[0072] Among them, the wearable device 1001 and the display device 1002 can be electrically connected through a magnetic connecting line 1003. The magnetic design can improve the convenience of installing and removing the magnetic connecting line 1003 between the wearable device 1001 and the display device 1002, thereby facilitating the use and storage of the extended reality device; the display device 1002 can include but is not limited to a variety of peripherals such as a gyroscope and a camera to meet functional requirements in different scenarios.

[0073] Obviously, those skilled in the art may make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if such changes and modifications fall within the scope of the claims and their equivalents, the present invention is intended to include such changes and modifications.
