Fig. 1-2 show schematic structural diagrams of some embodiments of AR display devices according to the present disclosure. As shown in fig. 1-2, the AR display device of the present disclosure may include: the display module assembly comprises a display module 1, a frame 2, at least two battery assemblies (such as a battery assembly 3 and a battery assembly 4), a power management unit 5 and a main control unit 6. Fig. 3 is a schematic structural view of a battery assembly disconnected from a frame according to some embodiments of an AR display device according to the present disclosure. In fig. 3, the battery assembly 3 and the battery assembly 4 are disconnected from the frame 2, respectively. Fig. 4 is a schematic diagram of a structure of contacts of a battery assembly and a frame according to some embodiments of an AR display device according to the present disclosure. In fig. 4, the frame includes 4 frame battery contacts (e.g., frame contacts 21, 22, 23, and 24) and 1 frame spring contact (e.g., frame spring contact 25), and the battery assembly includes 4 battery contacts (e.g., battery contacts 31, 32, 33, and 34) and 1 spring contact (e.g., spring contact 35).
In some embodiments, the AR display apparatus may include a display module, a frame, at least two battery packs, a power management unit, and a main control unit. The display module can be a module for displaying virtual images. For example, the display module may be composed of a micro display screen and an optical element. The frame may be a frame for supporting the AR display device. For example, the frame may be a spectacle frame. The battery module may be a module for supplying power. For example, the battery assembly may be a temple battery assembly in which the temple is integrally designed with the battery. The battery pack includes a battery label. The battery identifier is used for uniquely identifying the battery assembly. For example, when the AR display device includes two battery packs, the battery identifiers of the two battery packs may be "battery a" and "battery b". The Power Management Unit (PMU) may be a microcontroller. For example, the power management unit may be a microchip. The main control unit may be a unit that processes the received signal and controls other units or structures of the AR display device. For example, the main control unit may be an SoC (System on Chip). The main control Unit may be an MCU (micro controller Unit). The main control unit may also be a DSP (Digital Signal Processor).
In some embodiments, the battery assembly may include a battery, a battery contact, and a spring contact, and the battery may be electrically connected to the power management unit in an operating state. The battery contact may be a contact for energizing contact between devices. As an example, the battery contact may be a contact for connecting with a frame battery contact to supply power to the AR display device. For example, the battery contact may be a composite silver contact. The spring contacts may be contacts for connection to frame spring contacts. For example, the spring contact may be a metal leaf spring contact.
In some embodiments, the battery assembly may be detachably coupled to the frame. The frame may include frame battery contacts and frame spring contacts. The frame spring contact may include a thimble. Wherein, under the state that the battery assembly is connected with the frame, the battery contact can be connected with the frame battery contact, and the spring contact can be connected with the thimble. The frame battery contact may be a contact for connecting with a battery contact included in the battery pack to power on the AR display device. For example, the frame battery contact may be a composite silver contact. The frame spring contacts may be contacts for connection with spring contacts. For example, the frame spring contact may be a metal leaf spring contact including a thimble. When the battery pack is connected with the frame, the spring contact is connected with the ejector pin, so that the ejector pin is pressed into the AR display device by the spring contact, and a new electric signal is generated in a circuit included in the AR display device. In practice, the battery assembly and the frame are detachably connected through magnetic contacts or a buckle structure and the like.
In some embodiments, in a first disconnected state of the battery assembly from the frame, the ejector pin may be disconnected from the spring contact, and the battery contact may be connected to the frame battery contact. In a second disconnected state of the battery pack and the frame, the ejector pin may be disconnected from the spring contact, and the frame battery contact may be disconnected from the battery contact. Wherein the first off state precedes the second off state. That is, in the process of disconnecting the battery pack from the frame, the battery pack and the frame reach the first disconnection state first and then reach the second disconnection state, and thus, the disconnection of the battery pack from the frame is completed. When the battery assembly is in a first disconnected state with the frame, the battery contact can be connected with the frame battery contact, the AR display device is in a power-on state, and the ejector pin is ejected out of a mirror frame included in the AR display device under the action of the spring contact, so that a new electric signal is generated in a circuit included in the AR display device.
In some embodiments, the main control unit may be connected to the power management unit. In practice, the main control unit is electrically connected with the power management unit.
Optionally, the power management unit may be configured to: generating battery pack installation information in response to a battery installation signal generated on a circuit on which the power management unit is located; and sending the battery pack installation information to the main control unit. The battery installation signal may be an electrical signal generated on a circuit on which the power management unit is located by the thimble being pressed into the AR display device by the spring contact. The battery pack mounting information may be information indicating that the battery pack is connected to the frame. For example, the battery pack installation information may be "1".
Optionally, the power management unit may be further configured to: monitoring the residual battery capacity information of the electrically connected battery assembly; and sending the residual battery power information to the main control unit. The remaining battery power information may represent remaining power information of the electrically connected battery assembly. For example, the remaining battery power information may be 74. Indicating that the remaining capacity is 74 for a battery assembly with a full capacity state of 100. For another example, the remaining battery power information may be: [ cell a: v,50] and [ cell b: u,100 ]. Wherein, the v and u may be used to characterize whether the corresponding battery assembly is used for the current power supply path. For example, the "v" may characterize the battery assembly for the current power supply path. The "u" may characterize that the battery assembly is not used for the current power supply path. The above [ battery a: v,50] may indicate that a battery assembly with a battery label of "battery a" is used for the current power supply path and the remaining capacity is 50. The above-mentioned [ battery b: u,100] may indicate that the battery assembly with the battery label "battery b" is not used for the current power supply path and the remaining capacity is 100.
Optionally, the main control unit may be configured to: determining whether the residual capacity of the battery assembly for the current power supply path is smaller than a preset capacity threshold value or not according to the received residual battery capacity information; determining the number of the received battery pack installation information in response to determining that the remaining power of the battery pack for the current power supply path is less than the preset power threshold; in response to the fact that the number of the received battery pack installation information meets a preset number condition, determining whether the remaining power of the battery pack which is not used for the current power supply path is larger than the preset power threshold value or not according to the received remaining battery power information; in response to determining that the remaining power of the battery assembly which is not used for the current power supply path is greater than the preset power threshold, sending a signal for switching the current power supply path to the power management unit; and the power management unit is further configured to switch the current power supply path in response to receiving the switch current power supply path signal. The current power supply path may be a circuit that is supplying power. The battery pack for the current power supply path may be a battery pack that is releasing power to supply power to the AR display device. The remaining power may be a power remaining in the battery pack. The preset number condition may be that the number of the battery pack installation information is 2 or more. The aforementioned switching current power supply path signal may be a signal that characterizes switching of a battery assembly for the current power supply path. In practice, in response to receiving the signal for switching the current power supply path, the power management unit may switch the battery assembly corresponding to the current power supply path to the battery assembly not used for the current power supply path, so that the battery assembly not used for the current power supply path is used for the current power supply path after being switched, and supplies power to the AR display device. Therefore, when the AR display device comprises at least one battery pack, the battery pack with sufficient electric quantity can be switched to supply power for the AR display device when the electric quantity of the battery pack used for supplying power to the current power supply path is insufficient.
Optionally, the main control unit may be further configured to send a power-off signal to the power management unit in response to that the number of the received battery pack installation information does not satisfy the preset number condition; and the power management unit is further configured to close the current power supply path in response to receiving the power-off signal. In practice, the main control unit may transmit a power-off signal to the power management unit in response to the number of received battery pack installation information being 1. The power-off signal may be a signal indicating that the power supply path is turned off. Therefore, when the AR display device only comprises one battery pack and the battery pack is insufficient in electric quantity, the AR display device can be powered off, and the AR display device can be shut down.
Optionally, the main control unit may be further configured to send a power-off signal to the power management unit in response to determining that the remaining power of the battery assembly not used for the current power supply path is less than or equal to the preset power threshold; and the power management unit is further configured to close the current power supply path in response to receiving the power-off signal. Therefore, when the battery pack of the AR display device is insufficient in electricity, the AR display device can be powered off, and the AR display device can be shut down.
Optionally, the power management unit may be further configured to: in response to detecting that the working state of the AR display device is the first off state, receiving a battery exit signal generated on a circuit where the power management unit is located; generating battery pack exit information according to the battery exit signal; and sending the battery pack exit information to the main control unit. The battery exit signal may be a new electrical signal generated in a circuit in which the power management unit is located when the thimble is ejected from a mirror frame included in the AR display device under the action of the spring contact. The circuit in which the power management unit is located may be a circuit connected to the power management unit. The battery pack exit information may be information indicating that the battery pack corresponding to the battery exit signal and the lens frame are in the first disconnected state. For example, the battery pack exit information may be "2".
Optionally, the main control unit may be further configured to: determining the number of received battery pack installation information in response to receiving the battery pack exit information; in response to the fact that the number of the received battery pack installation information meets the preset number condition, determining whether the remaining power of the battery pack which is not used for the current power supply path is larger than the preset power threshold value or not according to the received remaining battery power information; in response to determining that the remaining power of the battery assembly which is not used for the current power supply path is greater than the preset power threshold, sending a signal for switching the current power supply path to the power management unit; and the power management unit is further configured to switch the current power supply path in the first off state in response to receiving the switch current power supply path signal. Therefore, in the process that the user actively disconnects the battery assembly and the mirror frame, when the battery assembly is not completely disconnected from the mirror frame and supplies power to the AR display device, the battery assembly corresponding to the current power supply path is switched, so that the battery assembly detached by the user does not supply power to the AR display device before the mirror frame is completely disconnected, and the phenomenon that the AR display device is shut down due to the fact that the battery assembly is actively detached by the user is avoided.
Optionally, the AR display device may further include a speaker. And the main control unit responds to the situation that the residual electric quantity of the battery pack for the current power supply path is smaller than the preset electric quantity threshold value, and controls the loudspeaker to play a charging prompt tone of the battery pack. The battery pack charging prompt tone may be an audio for prompting a user to charge the battery pack for the current power supply path. For example, the battery pack charging prompt tone may be: please charge the battery a in time. Therefore, the user can be prompted to charge the battery pack in time when the electric quantity of the battery pack is insufficient through the playing audio.
Optionally, the display module may include a left-eye display module and a right-eye display module. And the main control unit controls the display module to display the charging prompt information of the battery assembly in response to the fact that the residual electric quantity of the battery assembly for the current power supply path is smaller than the preset electric quantity threshold value. The battery pack charging prompt information may be a text for prompting a user to charge the battery pack. For example, the battery pack charging prompt message may be: please charge battery a. Therefore, the user can be prompted to charge the battery pack with insufficient electric quantity through the display characters.
Optionally, the AR display device may further include a camera. The camera is in communication connection with the main control unit. And the main control unit responds to the detected shooting starting information and controls the camera to shoot the external environment. The shooting start information may be information representing that the camera is started to shoot. For example, the above-described shooting start information may be "3". Thus, the imaging of the external environment in which the AR display device is located can be realized.
Optionally, the AR display device may further include a microphone. The microphone is in communication connection with the main control unit. And the main control unit responds to the detected recording starting information and controls the microphone to collect audio. The recording start information may be information representing that the microphone is started to collect audio. For example, the recording start information may be "4".
Optionally, the AR display device may further include a communication unit. The communication unit is connected with the main control unit. The communication unit comprises an antenna. Therefore, the communication between the AR display device and other equipment can be realized through the communication unit.
The above embodiments of the present disclosure have the following advantages: through the AR display device of some embodiments of this disclosure, on the premise of not influencing the use of wear-type AR equipment, the duration of a journey of wear-type AR equipment has been prolonged. Specifically, the reason why the duration of the head-mounted AR device cannot be extended without affecting the use of the head-mounted AR device is: need wired connection power supply unit, influence the use of wear-type AR equipment, lead to the experience that wear-type AR equipment used relatively poor, equally, adopt low-power consumption application can restrict wear-type AR equipment's use, further reduce the experience that wear-type AR equipment used and feel, in addition, built-in large capacity battery can reduce the comfort level that the user wore wear-type AR equipment, lead to wear-type AR equipment's practicality relatively poor. Can lead to wear-type AR equipment to shut down when changing external battery, can't increase the duration of a journey of AR glasses. Based on this, the AR display device of some embodiments of the present disclosure includes: display module assembly, frame, two at least battery pack, power management unit and master control unit. The battery assembly comprises a battery, a battery contact and a spring contact, and the battery is electrically connected with the power management unit in a working state. The battery pack is detachably connected to the frame. The frame includes frame battery contacts and frame spring contacts. The frame spring contact includes a thimble. Wherein, under the state that the battery component is connected with the frame, the battery contact is connected with the frame battery contact, and the spring contact is connected with the thimble. In a first disconnected state of the battery pack and the frame, the ejector pin is disconnected from the spring contact, and the battery contact is connected to the frame battery contact. In a second disconnected state of the battery pack and the frame, the ejector pin is disconnected from the spring contact, and the frame battery contact is disconnected from the battery contact. Wherein the first off state precedes the second off state. The main control unit is connected with the power management unit. From this, through two at least battery pack that AR display device includes, because the wired connection power supply unit has been avoided, also need not to adopt the low-power consumption to use, needn't embed large capacity battery, can not influence wear wearing. Also because set up first off-state and second off-state, after user's initiative disconnection picture frame and a battery pack's connection, AR display device can be supplied power by other battery packs, avoids user's initiative disconnection to lead to AR display device to shut down, and then has increased wear-type AR equipment's duration of endurance.
With continued reference to FIG. 5, a flow 500 of some embodiments of a method for sustained power supply of an AR display device is illustrated. The process 500 of the method for continuously supplying power to the AR display device includes the following steps:
In some embodiments, an executing entity of the AR display device continuous power supply method (e.g., the AR display device shown in fig. 1) may determine whether the remaining power of the battery assembly for the current power supply path is less than a preset power threshold according to the remaining battery power information. For example, the execution main body may determine whether a battery pack identified as "v" in the remaining battery capacity information, which characterizes whether a corresponding battery pack is used for the current power supply path, is used for the current power supply path. And determining whether the remaining capacity of the battery assembly identified as "v" is less than a preset capacity threshold. Thus, it can be determined whether the battery pack for the current power supply path is in a low power state.
In some embodiments, the execution subject may determine the number of the battery pack installation information in response to determining that the remaining power amount of the battery pack for the current power supply path is less than the preset power amount threshold. Thus, it may be determined whether the AR display apparatus includes a battery pack that is not used for the current power supply path when the battery pack for the current power supply path is not sufficiently charged.
In some embodiments, in response to the number of the battery pack installation information satisfying a preset number condition, the execution main body may determine whether a remaining power of a battery pack not used for the current power supply path is greater than the preset power threshold according to the received remaining battery power information. Thus, it is possible to determine whether the amount of power of the battery pack not used for the current power supply path is sufficient when the amount of power of the battery pack used for the current power supply path is insufficient and the AR display apparatus includes the battery pack not used for the current power supply path.
In some embodiments, the execution main body may switch the current power supply path in response to determining that the remaining power of the battery pack not used for the current power supply path is greater than the preset power threshold. In practice, in response to determining that the remaining power of the battery pack not used for the current power supply path is greater than the preset power threshold, the execution main body may switch the battery pack corresponding to the current power supply path. Therefore, when the electric quantity of the battery assembly used for the current power supply path is insufficient and the electric quantity of the battery assembly which is not used for the current power supply path and is included by the AR display device is sufficient, the power supply path is switched to the battery assembly which is not used for the current power supply path, so that the battery assembly which is not used for the current power supply path supplies power to the AR display device after switching.
The above embodiments of the present disclosure have the following advantages: by the AR display device continuous power supply method of some embodiments of the disclosure, the endurance time of the head-mounted AR equipment is prolonged on the premise of not influencing the use of the head-mounted AR equipment. In particular, the reason for the poor utility of head-mounted AR devices is: need wired connection power supply unit, influence the use of wear-type AR equipment, lead to the experience that wear-type AR equipment used relatively poor, equally, adopt low-power consumption application can restrict wear-type AR equipment's use, further reduce the experience that wear-type AR equipment used and feel, in addition, built-in large capacity battery can reduce the comfort level that the user wore wear-type AR equipment, lead to wear-type AR equipment's practicality relatively poor. Can lead to wear-type AR equipment to shut down when changing external battery, can't increase the duration of a journey of AR glasses. Based on this, the AR display device continuous power supply method of some embodiments of the present disclosure first determines whether a remaining power of a battery pack for a current power supply path is less than a preset power threshold according to remaining battery power information. Thus, it can be determined whether the battery pack for the current power supply path is in a low power state. Then, in response to determining that the remaining power of the battery pack for the current power supply path is less than a preset power threshold, the amount of battery pack installation information is determined. Thus, it may be determined whether the AR display apparatus includes a battery pack that is not used for the current power supply path when the battery pack for the current power supply path is not sufficiently charged. Secondly, in response to the fact that the quantity of the battery pack installation information meets a preset quantity condition, whether the residual electric quantity of the battery pack which is not used for the current power supply path is larger than a preset electric quantity threshold value is determined according to the received residual battery electric quantity information. Thus, it is possible to determine whether the amount of power of the battery pack not used for the current power supply path is sufficient when the amount of power of the battery pack used for the current power supply path is insufficient and the AR display apparatus includes the battery pack not used for the current power supply path. Finally, the current power supply path is switched in response to determining that the remaining capacity of the battery assembly which is not used for the current power supply path is greater than a preset capacity threshold. Therefore, when the electric quantity of the battery assembly used for the current power supply path is insufficient and the electric quantity of the battery assembly which is not used for the current power supply path and is included by the AR display device is sufficient, the power supply path is switched to the battery assembly which is not used for the current power supply path, so that the battery assembly which is not used for the current power supply path supplies power to the AR display device after switching. Therefore, the user can charge the battery pack which is not used for the current power supply path and has insufficient electric quantity after switching, so that the battery pack can supply power to the AR display device again after next switching processing. From this, through two at least battery pack, avoided wired connection power supply unit, also need not to adopt the low-power consumption to use, needn't embed large capacity battery, can not influence wear-type AR equipment's use and feel with experience, do not reduce the user and wear under the prerequisite of the comfort level of wear-type AR equipment, realize wear-type AR equipment longer duration to wear-type AR equipment's practicality has been promoted. Also because the scheme that these embodiments describe can realize that the user initiatively breaks off the picture frame and a battery pack's back, AR display device is supplied power by other battery packs, avoids the user initiatively to break off the connection and leads to AR display device to shut down, and then increases wear-type AR equipment's duration of endurance. Therefore, the duration of the head-mounted AR device can be prolonged on the premise of not influencing the use of the head-mounted AR device.
With continued reference to FIG. 6, a flow 600 of some embodiments of a method for sustained power supply of an AR display device is illustrated. The process 600 of the method for continuously supplying power to the AR display device includes the following steps:
In some embodiments, the specific implementation of steps 601-604 and the technical effect thereof can refer to steps 501-504 in those embodiments corresponding to fig. 5, which are not described herein again.
In step 605, in response to the operating state of the AR display device being the first off state, the number of battery pack installation information is determined.
In some embodiments, in response to the operating state of the AR display device being the first off state, an executing body of the AR display device continuous power supply method (e.g., the AR display device shown in fig. 1) may determine the number of battery pack installation information. Thus, the number of battery modules connected to the frame can be determined when it is confirmed that the user is to actively disconnect the frame from the battery modules.
In some embodiments, in response to the number of the battery pack installation information satisfying a preset number condition, the execution main body may determine whether a remaining power of a battery pack not used for the current power supply path is greater than the preset power threshold according to the received remaining battery power information. Thus, it is possible to determine whether the amount of power of the battery pack not used for the current power supply path is sufficient, while confirming that the user is to actively disconnect the mirror frame from the battery pack.
In some embodiments, the execution main body may switch the current power supply path in response to determining that the remaining power of the battery pack not used for the current power supply path is greater than the preset power threshold and the operating state of the AR display device is the first off state. In practice, in response to determining that the remaining power of the battery pack not used for the current power supply path is greater than the preset power threshold and that the operating state of the AR display device is the first off state, the execution main body may switch the battery pack corresponding to the current power supply path. Thus, the power supply path can be switched when it is confirmed that the user is actively disconnecting the lens frame from the battery pack and the lens frame is not completely disconnected from the battery pack.
As can be seen from fig. 6, compared with the description of some embodiments corresponding to fig. 5, the process 600 of the page display method in some embodiments corresponding to fig. 6 embodies the step of expanding the first disconnected state. Therefore, the solutions described in the embodiments can realize that the AR display device is powered by other battery assemblies after the user actively disconnects the glasses frame from one battery assembly, so that the AR display device is prevented from being shut down due to the active disconnection of the user, and the endurance of the head-mounted AR device is further prolonged.
