Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some, but not all, embodiments of the present application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

Please refer to fig. 1, which is a schematic structural diagram of a head-mounted electronic device according to an embodiment of the present disclosure. The head-mounted electronic device 100 may include: a frame 110, a temple 120, an antenna array 130, a first controller 140.

In this embodiment, the temples 120 may be connected to the frame 110. Wherein the temples 120 can be folded and unfolded, and thus the states of the temples 120 may include a folded state and an unfolded state. That is, the state of the temples 120 may include an unfolded state when the temples are completely unfolded and a folded state in which the temples are folded with respect to the frame. The antenna array 130 may include a plurality of antenna elements, wherein each antenna element may be disposed on at least one of the temple 120 and the frame 110. Each antenna element in the antenna array 130 may enable wireless communication connection with the head-mounted electronic device.

In this embodiment, the first controller 140 may be electrically connected to at least one antenna element 131 of the plurality of antenna elements. The first controller 140 may be configured to control the at least one antenna element 131 to operate in the unfolded state of the temple 120 and to control the at least one antenna element 131 to stop operating in the folded state of the temple 120. It should be noted that the first controller 140 controls the at least one antenna element 131 to stop operating, so that the first controller 140 controls the feeding power supply of the at least one antenna element 131 to stop supplying power to the at least one antenna element 131, thereby stopping the at least one antenna element 131 from operating. Alternatively, the first controller 140 may control at least one antenna element 131 to stop operating, and may also control the first controller 140 to turn off at least one antenna element 131, so that at least one antenna element 131 stops operating.

Therefore, when the user wears the head-mounted electronic device 100, the temple 120 of the head-mounted electronic device 100 may be unfolded, so that the first controller 140 may control the at least one antenna element 131 to be in the working state. Further, when the user finishes using the head-mounted electronic device 100, the user can remove the temple from the head-mounted electronic device 100 and fold the temple, and the first controller 140 can control the at least one antenna element 131 to stop working.

According to the head-mounted electronic device provided by the above embodiment of the application, when the user does not use the head-mounted electronic device 100 and folds the temple 120, the first controller 140 controls at least part of the antenna array elements in the head-mounted electronic device 100 to stop working, so that the power consumption of the head-mounted electronic device 100 can be reduced, the electric energy of the head-mounted electronic device 100 is saved, and the working duration of the head-mounted electronic device 100 is prolonged.

Alternatively, in order to enable the temples 120 to be unfolded or folded with respect to the frame 110, the temples 120 may be connected with the frame 110 by means of a hinge or the like. Of course, other ways of rotatably connecting the temple bar 120 to the frame 110 are not excluded.

It should be noted that the arrangement position and the arrangement number of the antenna elements (shown as black triangles in fig. 1) in fig. 1 are only an example. The antenna elements in the antenna array 130 may be disposed only on the temple 120, only on the frame 110, or both on the temple 120 and the frame 110. As an example, the antenna array 130 in fig. 1 may include 12 antenna elements, and in practical applications, the number of the antenna elements may also be less than 12, or more than 12. In summary, the number of antenna elements and the positions of the antenna elements in the antenna array 130 may be selected according to actual requirements.

It should be understood that in a normal case, when the temple 120 is in the unfolded state, the head-mounted electronic device 100 may be worn and used by a user, in which case the first controller 140 may control the at least one antenna element 131 to operate to provide a larger communication bandwidth; the temple 120 is in the folded state to indicate that the user is not using the head-mounted electronic device 100, for example, the user places the head-mounted electronic device 100 somewhere, in which case the communication bandwidth may be required to be small, and the first controller 140 may control the at least one antenna element 131 to stop working. The specific number of the at least one antenna element 131 controlled by the first controller 140 can be determined by those skilled in the art according to practical requirements, and is not limited specifically here.

In the above-described embodiment of controlling the at least one antenna element 131 to operate or stop operating as a whole according to the state of the temple 120, the first controller 140 may have various implementations.

Alternatively, to facilitate implementation of the embodiment of the present application, the first controller 140 may include a simple structure, such as a circuit structure, etc., so as to directly send out a simple signal for controlling the at least one antenna element 131 according to the state of the temple 120.

As an example, as shown in fig. 2, for a schematic structural diagram of a first controller of a head-mounted electronic device provided according to an embodiment of the present application, the first controller 140 may include: the high/low level switching circuit 141 is electrically connected to the at least one antenna element 131, and is operable to output a high level in an unfolded state of the temple 120 and a low level in a folded state of the temple 120. The high level output by the high-low level switching circuit 141 can be used to control the operation of the connected antenna elements. That is, the high-level signal output from the high-low level switching circuit 141 can open the antenna element electrically connected thereto, so that power feeding can be received. The low level output from the high-low level switching circuit 141 can be used to control the connected antenna elements to stop working. That is, the low-level signal output from the high-low level switching circuit 141 can turn off the antenna element electrically connected thereto, so that power feeding may not be received. Here, the high/low level switching circuit 141 in fig. 2 may be electrically connected to the antenna elements 1311 to 1313 of the at least one antenna element 131, and the like, so as to output a level corresponding to the state of the temple 120 to the at least one antenna element 131.

As an example, as shown in fig. 3, a circuit schematic diagram of the high-low level switching circuit shown in fig. 2 is shown. Here, the high-low level switching circuit 141 may include: NPN transistor Q, as shown in fig. 3. The collector of the NPN transistor Q is electrically connected to the power VCC of the head-mounted electronic device 100 through the first resistor R1, the emitter of the NPN transistor Q is grounded through the second resistor R2, the base of the NPN transistor Q is grounded through the third resistor R3, and is electrically connected to the fourth resistor R4 and the power VCC through the key S.

The at least one antenna element 131 may be connected to the high/low level switching circuit 141 through the high/low level output point. The key S may be replaced by other elements such as a hardware switch, and may be used to control the high-low level switching circuit 141 to be turned on or off. The resistors R1-R4 can limit current in the circuit and play a role of protecting the circuit.

As shown in fig. 3, it should be noted that the power VCC in the high-low level switching circuit 141 may be a power for feeding the antenna array 130 or a power for feeding the at least one antenna element 131, or may be a power provided separately, which is not limited in this embodiment of the application.

As shown in fig. 3, when the temple 120 is in the folded state, the button S is turned off (for example, the button S may be provided at the connection of the temple 120 and the frame so that the control button S is deformed to be turned off when the temple 120 is folded), and the high-low level switching circuit 141 is turned off. At this time, the connection point 1 is at a low level, the high-low level output point is at a high level, the NPN transistor Q is turned off, and the at least one antenna element 131 is turned off and cannot obtain current, thereby stopping working. When the temple 120 is in the unfolded state, the button S is closed, and the high-low level switching circuit 141 is turned on. At this time, the connection point 1 is at a high level, the high-low level output point is at a low level, the NPN transistor Q is turned on, and the at least one antenna element 131 is turned on and can obtain a current, thereby being in a working state.

Of course, the NPN type transistor Q in fig. 3 may be adjusted to be a PNP type transistor, and the connection manner between other elements in the high-low level switching circuit 141 and the PNP type transistor is also adjusted correspondingly, so that the function of the high-low level switching circuit 141 in the head-mounted electronic device 100 according to the embodiment of the present application can also be implemented.

In summary, the high-low level switching circuit 141 shown in fig. 3 can directly convert the state of the temple 120 into a high-low level signal that can control whether at least one antenna element 131 stops operating. In addition, the circuit diagram in fig. 3 is merely an example, and actually, the above-described functions may be implemented by using different circuits.

In another alternative implementation, the first controller 140 may include: a mechanical switch 142. The mechanical switch 142 may be connected between a power source and the at least one antenna element 131. Wherein the power supply may supply power to the at least one antenna element 131, and the mechanical switch 142 may be turned off in the folded state of the temple 120, thereby stopping the at least one antenna element 131. The mechanical switch 142 may be turned on in the unfolded state of the temple 120, thereby enabling the at least one antenna element 131 to operate. This implementation simplifies the structure of the first controller 140, and reduces the occupied space of the first controller 140, thereby reducing the cost of the head-mounted electronic device and reducing the volume of the head-mounted electronic device.

The following describes in detail the setting position and the operation principle of the mechanical switch 142 in the head-mounted electronic device 100 according to the embodiment of the present application, by taking fig. 4 to fig. 7 as an example. Here, the temple 120 may be a first temple 121, a second temple 122, and the frame 110 may be similar.

Fig. 4 is a schematic position diagram of a mechanical switch in an unfolded state of a temple of a head-mounted electronic device according to an embodiment of the present application. In fig. 4, the mechanical switch 142 may be fixedly disposed on the frame 110, the temple 120 and the frame arm 111 may be connected by the connecting member 410, and the mechanical switch 142 may be a mechanical button. Accordingly, the temple 120 may press the mechanical switch 142 when being unfolded, thereby making the mechanical switch 142 conductive. The frame arm 111 may be a support extending from the frame 110 to connect the temple 120 and the frame 110.

The connecting element 410 may be an element for connecting the frame branch 111 and the temple 120, such as a hinge. When the user folds the temples 120 in the unfolded state or unfolds the temples 120 in the folded state, one end of the temples 120 connected with the frame 110 may be rotated around one end of the frame branches 410 by the connecting member 410.

Further, the region a in fig. 4 will be described with reference to fig. 5. Fig. 5 is a partial structural schematic diagram of the head-mounted electronic device shown in fig. 4. As shown in fig. 5, when the temple 120 is in the unfolded state, one end of the temple 120 near the frame 110 presses the mechanical switch 142, so that the length of the key, which is exposed outside the mechanical switch 142, is shortened to x, thereby turning on the mechanical switch 142.

Fig. 6 is a schematic position diagram of a mechanical switch in a folded state of a temple of a head-mounted electronic device according to an embodiment of the present application. Similar to fig. 4, in fig. 6, mechanical switch 142 may be fixedly disposed on frame 110, temple 120 and frame arm 111 are connected by connecting member 410, and mechanical switch 142 may be a mechanical button. Accordingly, the temple 120 may be disengaged from contact with the mechanical switch 142 when folded, thereby causing the mechanical switch 142 to turn off.

Further, the region B in fig. 6 will be described with reference to fig. 7. Fig. 7 is a partial structural schematic diagram of the head-mounted electronic device shown in fig. 6. As shown in fig. 7, when the temple arm 120 is in the folded state, the end of the temple arm 120 close to the frame 110 is not in contact with the mechanical switch 142, so that the button of the mechanical switch 142 is bounced, and the length of the button exposed outside is the same as the full button length y, so that the mechanical switch 142 is turned off. Wherein the length y of the mechanical key bounce is typically greater than the length x of the mechanical key being pressed.

Alternatively, the mechanical switch 142 may also be a normal circuit switch. The closing of the mechanical switch 142 may enable the circuit at both ends to be connected through the mechanical switch 142, and the resistance value of the mechanical switch 142 may be negligible, and the mechanical switch 142 may be equivalent to a wire in the circuit. Therefore, when the mechanical switch 142 is closed, the mechanical switch 142 connects the at least one antenna element 131 with the power supply of the head-mounted electronic device 100 for feeding the at least one antenna element 131, so that the power supply of the head-mounted electronic device 100 can supply power to the at least one antenna element 131, thereby enabling the at least one antenna element 131 to start operating. When the mechanical switch 142 is turned off, the mechanical switch 142 may disconnect the at least one antenna element 131 from the power supply of the head-mounted electronic device 100, so that the power supply of the head-mounted electronic device 100 stops supplying power to the at least one antenna element 131, and the at least one antenna element 131 can stop working.

Of course, it should be understood that the key S in the high and low level switching circuit 141 shown in fig. 3 may also be implemented by using the mechanical switch 142 to function to turn off or on the high and low level switching circuit 141 according to the state of the temple 120.

It should be noted that, the selection and the setting position of the mechanical switch 142 in fig. 4 to fig. 7, and the connection manner and the relative position of the temple 120 and the frame 110 are only examples to facilitate understanding of the technical solution of the present application, and the embodiment of the present application does not limit the specific implementation thereof.

Alternatively, as in the examples in fig. 4 and 6, in order to be able to timely acquire the change of the state of the temple 120, in the head-mounted electronic device 100 provided in the embodiment of the present application, the mechanical switch 142 may be disposed at the connection between the frame 110 and the temple 120.

Alternatively, the mechanical switch 142 may be provided at an end of the temple 120 remote from the connection with the frame 110, or at a position on the frame 110 capable of contacting or approaching the temple 120 when folded.

Of course, in addition to the method of directly controlling the antenna elements by using the high-low level switching circuit 141 or the mechanical switch 142, the embodiments of the present application may also control the antenna elements by the processor 143. It will be appreciated that there are many implementations possible for the first controller including the processor 143.

It is to be understood that the manner of acquiring the state of the temples 120 may be various, and the state of the temples 120 may be acquired through various sensors, etc., in addition to the structure of the mechanical switch 142, etc. Fig. 8 is a schematic structural diagram of a first controller in a head-mounted electronic device according to an embodiment of the present application. As shown in fig. 8, the first controller 140 may include a temple state collector 144 and a processor 143. The temple status acquirer 144 may acquire status indication information. Wherein the status indication information may be used to indicate the status of the temples 120. The processor 143 may include a signal input terminal and a signal output terminal. Wherein the signal input terminal can receive the status indication information, and the signal output terminal can be electrically connected to the at least one antenna element 131. The processor 143 may determine the state of the temple 120 according to the state indication information, and control the at least one antenna element 131 to operate when the temple 120 is in the unfolded state, and control the at least one antenna element 131 to stop operating when the temple 120 is in the folded state.

In this way, the temple state collector 144 may be disposed at different positions of the head-mounted electronic device 100 according to the requirement of collecting the state indication information, and is not limited to a fixed position such as a connection position of the frame 110 and the temple 120, so that the development designer can arrange the internal and external structures of the head-mounted electronic device 100 more flexibly. The processor 143 can determine the state of the temple 120 according to the state indication information collected by the temple state collector 144, and directly turn on or turn off the antenna element connected to the temple 120 according to the determined state of the temple 120.

Here, after the processor 143 receives the state information of the temple 120, it may generate a corresponding enable signal according to the state information of the temple 120, and transmit the enable signal to the antenna element electrically connected to the processor 143. The enable signal may directly control the on and off of the antenna element electrically connected thereto, so that the processor 143 may control whether the antenna element operates according to the status indication information.

Alternatively, in addition to the processor 143 directly controlling the operation or the stop of the at least one antenna element 131, the processor 143 may control whether the feeding circuit feeds the at least one antenna element 131 to control whether the at least one antenna element operates. The feeding circuit may be a circuit structure capable of providing power to the at least one antenna element 131, for example, a circuit including a power supply, etc.

For example, fig. 9 is a schematic structural diagram of a first controller in a head-mounted electronic device according to an embodiment of the present application. As shown in fig. 9, the first controller 140 may include a temple-state collector 144, a power feeding circuit 145, and a processor 143. The temple status acquirer 144 may acquire status indication information. Wherein the state indicating information is used to indicate the state of the temples 120. The feeding circuit 145 may include a feeding control terminal and a feeding output terminal. Wherein the feed output is electrically connected to at least one antenna element 131. A signal input end of the processor 143 may receive the status indication information collected by the temple status collector 144, and a signal output end of the processor 143 may be electrically connected to the feeding control end of the feeding circuit. The processor 143 may include a signal input terminal and a signal output terminal. The signal input end can be used for receiving the state indication information, and the signal output end can be electrically connected with the feed control end. The processor 143 may determine the state of the temple 120 according to the state indication information, and control the feeding output terminal to feed power to the at least one antenna element 131 through the feeding control terminal when the temple 120 is in the unfolded state, and control the feeding output terminal to stop feeding power to the at least one antenna element 131 through the feeding control terminal when the temple 120 is in the folded state.

In this way, the temple-state acquirer 144 provided at an arbitrary position of the head-mounted electronic apparatus 100 may transmit the acquired state indication information to the processor. Then, the processor 143 may determine the state of the temple 120 according to the correspondence of the state indication information and the state of the temple 120. The processor 143 may send a control signal to the feeding circuit 145 according to the state of the temple 120, so that the feeding circuit 145 stops or starts to supply power to the at least one antenna element 131, thereby controlling whether the at least one antenna element 131 operates.

The status indication information of the temple 120 may include a relative positional relationship between the temple 120 and the frame 110, and then, according to the relative positional relationship between the temple 120 and the frame 110, a distance between an end of the temple 120 far from the connection and the frame 110 may be determined, where the distance may represent a status of the temple 120. Here, the connection point may be a distance between the temple 120 and the frame 110.

For example, in order to be able to intuitively determine the state of the temples 120 according to the distance between the temples 120 and the frame 110, the temple-state collector 144 may include a ranging sensor 1441. The ranging sensor 1441 is disposed on the temple 120, and the ranging sensor 1441 may collect distance information between the ranging sensor 1441 and the frame 110, wherein the distance information may be used to indicate a state of the temple 120. It should be understood that when the ranging sensor 1441 is disposed on the temple 120, a lens or a light emitting opening of the ranging sensor 1441, etc. may be aligned with the frame 110 to accurately acquire distance information of the ranging sensor 1441 from the frame 110.

It should be understood that fig. 10 is a schematic structural diagram of a first controller in a head-mounted electronic device according to an embodiment of the present application. An output of the ranging sensor 1441 may be connected to a signal input of the processor 143, and a signal input of the processor 143 may be connected to at least one antenna element 131.

Fig. 11 is a schematic structural diagram of a first controller in a head-mounted electronic device according to an embodiment of the present disclosure. Of course, the output terminal of the ranging sensor 1441 may be connected to the signal input terminal of the processor 143, the signal input terminal of the processor 143 is connected to the feeding control terminal of the feeding circuit 145, and the feeding output terminal of the feeding circuit 145 is connected to at least one antenna element 131.

The position of the ranging sensor 1441 on the temple 120 may be an end of the temple 120 far from a connection between the temple 120 and the frame 110, or may be a position of the temple 120 far from a connection between the temple 120 and the frame 110 by a preset length, which is not limited in this embodiment of the application.

Optionally, the ranging sensor 1441 may also be disposed on the frame 110, and the ranging sensor 1441 may collect distance information between the ranging sensor 1441 and the temple 120, wherein the distance information between the ranging sensor 1441 and the temple 120 may also be used to indicate a state of the temple 120. It should be understood that when the ranging sensor 1441 is disposed on the frame 110, a lens or a light emitting opening of the ranging sensor 1441 may be aligned with the temple 120 to accurately acquire distance information of the ranging sensor 1441 from the temple 120.

The position of the ranging sensor 1441 on the frame 110 may be the center position of the frame 110, or may be a position on the frame 110 where the distance is a preset length from the center point of the frame 110, which is not limited in the embodiment of the present application.

For another example, the ranging sensor 1441 included in the temple-state collector 144 may be further configured to collect distance information between the ranging sensor 1441 and the temple 120 when the ranging sensor 1441 is disposed on the frame 110, wherein the distance information is used to indicate the state of the temple 120.

The status indication information of the temple 120 may include a relative positional relationship between the temple 120 and the frame 110, and then, according to the relative positional relationship between the temple 120 and the frame 110, a distance between the frame 110 and one end of the temple 120 far away from the connection with the frame 110 may be determined, so as to determine whether the temple 120 is in the folded state or in the unfolded state.

To facilitate understanding of the process by which the processor 143 controls the at least one antenna element 131 in accordance with the status indication information of the temple 120, the following example is provided. If the processor 143 determines that the distance between the temple 120 and the frame 110, which is acquired by the distance measuring sensor 1441, is greater than or equal to the first preset distance, it may indicate that the temple 120 is in the unfolded state. The processor 143 may control the operation of the at least one antenna element 131 or control the feeding circuit 145 to feed the at least one antenna element 131. If the processor 143 determines that the distance between the temple 120 and the frame 110, which is obtained by the distance measuring sensor 1441, is less than or equal to the second preset distance, it may indicate that the temple 120 is in the folded state, and at this time, the processor 143 may control the at least one antenna element 131 to stop working, or control the feeding circuit 145 to stop feeding the at least one antenna element 131. Wherein the first predetermined distance is generally greater than the second predetermined distance.

Fig. 12 is a schematic structural diagram of a first controller in a head-mounted electronic device according to an embodiment of the present application. Alternatively, as shown in fig. 12, when the state of the temples 120 is determined according to the distance between the temples 120 and the frame 110, the temple state acquirer 144 may further include a high-low level switching circuit 1442. The high-low level switching circuit 1442 may output different level signals when the temples are in different states. Wherein a level signal may be used to indicate the state of the temples 120, the level signal including a high level and a low level. For example, the temple 120 may be determined to be in the unfolded state according to a high-level signal from the high-low level switching circuit 1442, and the temple 120 may be determined to be in the folded state according to a low-level signal from the high-low level switching circuit 1442.

In this way, a developer can design the circuit structure, the setting position, and the corresponding relationship between the level signal and the state of the temple 120 of the high-low level switching circuit 1442 according to actual needs, so that the processor 143 can determine the state of the temple 120 according to the level signal sent by the high-low level switching circuit 1442 and the corresponding relationship, and thereby control whether the at least one antenna array element 131 works.

For example, when the output terminal of the high-low level switching circuit 1442 may be connected to the signal input terminal of the processor 143, and the signal output terminal of the processor 143 is connected to the at least one antenna element 131, the high-low level switching circuit 1442 may output a high-low level signal for indicating the state of the temple 120 to the processor 143, so that the processor may send an enable signal to the antenna element connected thereto according to the high-low level signal to control whether the antenna element connected thereto operates.

For another example, as shown in fig. 13, it is a schematic structural diagram of a first controller in a head-mounted electronic device according to an embodiment of the present application. When the output end of the high-low level switching circuit 1442 is connected to the signal input end of the processor 143, the signal output end of the processor 143 is electrically connected to the feed control end of the feed circuit, and the feed output end of the feed circuit is connected to the at least one antenna element 131, the high-low level switching circuit 1442 may output a high-low level signal for indicating the state of the temple 120 to the processor 143, so that the processor sends a control signal to the feed circuit according to the high-low level signal to control whether the feed circuit supplies power to the antenna element connected thereto.

For ease of understanding, as an example, the internal structure of the high-low level switching circuit 1442 in the temple-state collector 144 may be the high-low level switching circuit 141 in the first controller shown in fig. 3. In this example, the high level output by the high-low level switching circuit 1442 may be used to indicate the unfolded state of the temple 120, and the low level output by the high-low level switching circuit 1442 may be used to indicate the folded state of the temple 120.

It is understood that the high-low level switching circuit in fig. 13 can also be implemented in other ways. For example, an inverter is added to the high-low level switching circuit shown in fig. 3 as the high-low level switching circuit in fig. 13. At this time, the high level output by the high-low level switching circuit 1442 can be used to indicate the folding state of the temple 120, and the processor 143 can control the at least one antenna element 131 to stop working, or control the feeding circuit 145 to stop feeding the at least one antenna element 131. The low level output from the high-low level switching circuit 1442 may be used to indicate the unfolding state of the temple 120, and the processor 143 may control the at least one antenna element 131 to operate or control the feeding circuit 145 to feed the at least one antenna element 131.

Fig. 14 is a schematic diagram of a connection relationship between a device parameter collector and a first controller in a head-mounted electronic device according to an embodiment of the present application. As shown in fig. 14, the head-mounted electronic device 100 may further include a device parameter collector 146. The device parameter collector 146 may be configured to collect a parameter related to an operating state of the head-mounted electronic device 100. The acquired parameters can represent the environment state of the head-mounted electronic equipment and the operation condition of the head-mounted electronic equipment. Wherein, the signal input end of the processor 143 can also be electrically connected with the output end of the device parameter collector 146. The processor 143 may be configured to determine an operational state of the at least one antenna element 131 based on the state of the temple 120 and to adjust the operational state of the antenna elements in the antenna array 130 based on a parameter related to the operation of the head-mounted electronic device 100.

It is understood that, those skilled in the art can determine, according to the needs of the world, antenna elements that are adjusted by the processor 143 according to parameters related to the operation of the head-mounted electronic device 100, and the determined antenna elements may include the at least one antenna element 131 or may not include the at least one antenna element 131, which is not limited by the embodiment of the present application. Accordingly, the processor 143 may adjust all antenna elements in the antenna array 130 or adjust some antenna elements in the antenna array 130 according to a parameter related to the operation of the head-mounted electronic device 100.

It should be understood that in the embodiments of the present application, there are many parameters related to the operating state of the head-mounted electronic device 100. For example, at least one of WIFI connection state parameters of the head-mounted electronic device 100, ambient light information where the head-mounted electronic device 100 is located, traffic information of the head-mounted electronic device 100, a remaining power of the head-mounted electronic device 100, and the like may be included. Of course, it is not excluded that other operation state related parameters affecting the control of the antenna elements exist, and there is no specific limitation here.

Accordingly, the device parameter collector 146 may include one or more collecting devices. Fig. 15 is a schematic view of a device parameter collector in a head-mounted electronic device according to an embodiment of the present application. In order to determine the operating state of each antenna element by integrating the operating states of the head-mounted electronic device 100 as much as possible, as shown in fig. 15, the device parameter collector 146 and the collected parameters related to the operating state of the head-mounted electronic device 100 may include at least one of the following: the WIFI connection parameter collector 1461 may collect WIFI connection state parameters of the head-mounted electronic device 100; an ambient light information collector 1462 configured to collect ambient light information of the head-mounted electronic device 100; the power parameter collector 1463 may collect remaining power information of the head-mounted electronic device 100.

It should be understood that the power parameter collector 1463 collects the remaining power information of the power supply for supplying power to the head-mounted electronic device 100, and is not the above-mentioned power supply for feeding the at least one antenna element 131.

More specifically, the WIFI connection status information of the head mounted electronic device 100 may include whether the head mounted electronic device 100 is connected to WIFI, the ambient light information of the head mounted electronic device 100 may include the light intensity of the environment where the head mounted electronic device 100 is located, the remaining power information of the head mounted electronic device 100 may include the percentage of power remaining in the head mounted electronic device 100, and so on.

The control of the antenna elements of the at least one antenna element 131 by the first controller 140 is illustrated below with reference to specific examples. As an example, if the temple 120 is determined to be in the folded state according to the data collected by the temple state collector 144, and the head-mounted electronic device 100 is determined to be connected to WIFI according to the data collected by the WIFI connection state collector 1461 in the device parameter collector 146, the processor 143 may determine that the user does not wear the head-mounted electronic device 100. At this time, the data transmission requirement of the head-mounted electronic device 100 is low, it is not necessary to use a data transmission capability with strong directivity and/or high transmission rate, and basic data communication when the head-mounted electronic device 100 is in standby can be maintained through WIFI. Then the processor 143 may control the at least one antenna element 131 (including all high frequency antenna elements in the antenna array 130) to stop operating.

As another example, if the temple 120 is determined to be in the folded state according to the data collected by the temple state collector 144 and the head-mounted electronic device 100 is determined not to be connected to WIFI according to the data collected by the WIFI connection state collector 1461 in the device parameter collector 146, the processor 143 may determine that the user does not wear the head-mounted electronic device 100. In this case, the data transmission requirement of the head-mounted electronic device 100 is low, and it is not necessary to use data transmission capability with strong directivity and/or high transmission rate, but a small number of antenna elements are required to operate to maintain basic data communication when the head-mounted electronic device 100 is in standby. Then the processor 143 may control the at least one antenna element 131 (including a small number of antenna elements in the antenna array 130) to operate, and the remaining antenna elements in the antenna array 130 to stop operating.

As another example, if the temple 120 is determined to be in the unfolded state according to the data collected by the temple state collector 144, and the head-mounted electronic device 100 is determined not to be connected to WIFI according to the data collected by the WIFI connection state collector 1461 in the device parameter collector 146, the processor 143 may determine that the user is wearing the head-mounted electronic device 100. At this time, the data transmission required by the head-mounted electronic device 100 needs to be high, data transmission capability with strong directivity and/or high transmission rate needs to be used, and no WIFI is provided for providing data communication for the head-mounted electronic device 100. Then the processor 143 may control to keep the at least one antenna element 131 (including all high frequency antenna elements in the antenna array 130) active.

As another example, if the temple 120 is determined to be in the unfolded state according to the data collected by the temple state collector 144 and the head-mounted electronic device 100 is determined to be connected to WIFI according to the data collected by the WIFI connection state collector 1461 in the device parameter collector 146, the processor 143 may determine that the user is wearing the head-mounted electronic device 100. At this time, data transmission required by the head-mounted electronic device 100 needs to be high, and data transmission capability with strong directivity and/or high transmission rate needs to be used, but some data communication can be provided for the head-mounted electronic device 100 through WIFI. Then the processor 143 may control the at least one antenna element 131 (including a portion of the antenna elements in the antenna array 130) to stop operating.

Optionally, as an embodiment, the at least one antenna element 131 is formed by all antenna elements of the antenna array 130. That is, the first controller 140 may control all antenna elements in the antenna array 130, so as to achieve unified control of whether all antenna elements in the head-mounted electronic device 100 operate or not by the first controller 140, thereby controlling the data transmission function of the head-mounted electronic device 100 to be turned on or off.

Or, optionally, as another embodiment, in addition to the at least one antenna element 131, other antenna elements are included in the plurality of antenna elements of the antenna array 130. Typically, the other antenna elements may remain in a normally open state. That is, the first controller 140 may only control a part of the antenna elements in the antenna array 130, so as to control the part of the antenna elements in the head-mounted electronic device 100 to stop working, thereby reducing the power consumption of the head-mounted electronic device 100.

Further, when the at least one antenna element 131 does not include all antenna elements in the antenna array 130, in order to be able to uniformly control the operating states of all antenna elements in the antenna array 130 through one controller, the head-mounted electronic device 100 may further include a second controller. The second controller may control the feeding states of all the antenna elements in the antenna array 130 according to the state of the temple 120, or may not control the feeding states of the antenna array 130 according to the state of the temple 120. Suppose that the head-mounted electronic device 100 now has m antenna elements turned on and n antenna elements turned off. At this time, the second controller may control to stop feeding the m + n antenna elements, or to restore the feeding state of the m + n antenna elements to: and feeding m + n antenna elements.

It should be understood that in the present example, there are many ways in which the second controller may be implemented. For example, the second controller may also directly control whether the antenna elements in the antenna array 130 stop operating. Of course, other implementations are possible, and the embodiments of the present application are not limited thereto. In addition, the embodiment of the present application is not limited to the setting position of the second controller.

It should be understood that the head-mounted electronic device 100 generally has two temples, namely a first temple and a second temple, and also has two frames, namely a first frame and a second frame (here, two frames refer to frames respectively corresponding to each eye of a user). Correspondingly, when the antenna array element is controlled, the working state or the feeding state of the two parts of antenna array elements can be respectively controlled. The two antenna elements refer to the first antenna element and the second antenna element. The antenna elements of the first part may include antenna elements of the at least one antenna element 131 disposed on the first temple and the first frame, and the antenna elements of the second part may include antenna elements of the at least one antenna element 131 disposed on the second temple and the second frame.

For example, the first controller 140 in the head-mounted electronic device 100 provided by the embodiment of the present application may include a first road controller and a second road controller. The first road controller may be configured to control the antenna elements of the at least one antenna element 131 that are disposed on the first temple 121 and the first frame 111. The second router may be configured to control the antenna elements of the at least one antenna element 131 disposed on the second temple 122 and the second frame 112.

As an example, when one side of the head-mounted electronic device 100 is close to the interactive device, the temple close to the interactive device may be unfolded, and the temple far from the interactive device may be folded, so as to control whether the two-part antenna element works or not. For example, when the first glasses frame and the first temple are close to the interactive device and the second glasses frame and the second temple are far from the interactive device, the first temple may be unfolded and the second temple may be folded, so that the first router controls the antenna elements of the first part to operate, and the second router controls the antenna elements of the second part to stop operating.

It should be understood that when the antenna array element is controlled, the working state or the feeding state of the two antenna array elements can also be controlled according to the state of one temple, so that the user can control the antenna array element with one hand.

For example, the first controller 140 in the head-mounted electronic device 100 provided in the embodiment of the present application may further include one of the first router or the second router, so that whether the at least one antenna element 131 (including the antenna elements disposed on the first temple 121 and the first frame 111 and the antenna elements disposed on the second temple 122 and the second frame 112) operates may be controlled according to a state of one of the first temple 121 or the second temple 122.

As an example, when the user wears or takes off the head-mounted electronic device 100 with one hand, the user may control whether all antenna elements of the at least one antenna element 131 are operated by unfolding or folding one temple. It will be appreciated that the controller controlling the at least one antenna element 131 may be selected according to the left and right hand usage habits of the user.

Optionally, in the head-mounted electronic device 100 provided in this embodiment of the application, at least some of the antenna elements of the at least one antenna element 131 may be disposed at an upper edge and a lower edge of the frame 110, where the upper edge and the lower edge of the frame 110 refer to mirror edges located at two sides of a horizontal center line of the frame 110, and when the user wears the head-mounted electronic device 100, a mirror edge near an eyebrow of the user is the upper edge, and another mirror edge is the lower edge.

For example, as shown in fig. 16, a schematic diagram of an antenna element in a head-mounted electronic device is provided according to an embodiment of the present application. In fig. 16, the antenna elements are indicated by black triangles, and the directions of arrows indicate the orientations of the antenna elements and the signal transmission directions. In order to avoid the limitation of the transmission direction of the 5G signal with strong directivity by the arrangement direction of the antenna elements, the antenna elements may be arranged at various positions of the head-mounted electronic device 100, such as the upper edge and the lower edge of the frame 110 and the temple 120. The signal transmission direction of the antenna elements disposed on the upper edge of the frame 110 is upward, the signal transmission direction of the antenna elements disposed on the lower edge of the frame 110 is downward, and the signal transmission direction of the antenna elements disposed on the temple 120 is toward the outside of the head-mounted electronic device 100.

Optionally, in order to enable the user to wear the head-mounted electronic device 100 away from the interactive device, and still enable the head-mounted electronic device 100 to perform data transmission with the interactive device, in the head-mounted electronic device 100 provided in the embodiment of the present application, at least a part of the at least one antenna element 131 may be disposed at an end of the temple 120 away from a connection with the frame 110, where an end of the temple 120 away from a connection with the frame 110 is generally located at a portion for hooking an ear of the user. As shown in fig. 16,

antenna elements

1314 and 1315 may be provided at the end of the temple 120 remote from the connection with the frame 110. Thus, when the user wears the head-mounted electronic device 100, the

antenna elements

1314 and 1315 enable the temple part located on the back side of the head of the user to have signals, so that the signal coverage range is expanded, and the communication effect of the head-mounted electronic device is improved.

Furthermore, if the array elements on the temple and the frame are arranged as shown in fig. 14, the head-mounted electronic device 100 can have signals all around the head of the user. The antenna elements disposed on the upper and lower sides of the frame 110 may enable signals to be provided on the upper and lower sides of the head-mounted electronic device 100. Finally, when the user wears the head-mounted electronic apparatus 100, the parts of the head-mounted electronic apparatus 100 located at various positions on the user's head can receive or transmit signals.

Optionally, in order to improve the data transmission efficiency of the head-mounted electronic device 100, the antenna array 130 in the head-mounted electronic device 100 provided in the embodiment of the present application may be a 5G antenna array. Then, the above design of disposing the

antenna elements

1314 and 1315 at the end of the temple 120 away from the connection with the frame 110 can avoid that the 5G signal cannot be transmitted because the antenna elements are not facing the interactive device. Of course, the antenna array 130 may be other than 5G.

Optionally, in the head-mounted electronic device 100 provided in the embodiment of the present application, all active antenna elements in the antenna array 130 may have the capability of collectively providing the head-mounted electronic device 100 with network residence and communication in the preset communication mode.

Optionally, the head-mounted electronic device 100 may further include a WIFI module, and all working antenna elements in the antenna array 130 and the WIFI module in the head-mounted electronic device 100 have a capability of providing network residence and communicating in a preset communication mode for the head-mounted electronic device 100 together. The preset communication mode may include, for example, a normal communication mode and a low-speed communication mode, and the like. The normal communication mode usually requires more communication bandwidth, and the low-speed communication mode requires less communication bandwidth. The sleep mode may be understood as a low speed communication mode. For example, the normal communication mode may be an operation mode of the head-mounted electronic device 100 when the temple 120 is unfolded, including a mode that requires operation of all antenna elements in the antenna array 130. The low-speed communication mode may be an operation mode of the head-mounted electronic device 100 when the temple 120 is folded, including a mode requiring operation of a part of the antenna elements in the antenna array 130.

It is to be noted that the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising an … …" does not exclude the presence of other like elements in a process, method, article, or apparatus that comprises the element.

The embodiments in the present specification are described in a progressive manner, and the same and similar parts among the embodiments are referred to each other, and each embodiment focuses on the differences from the other embodiments. In particular, for the system embodiment, since it is substantially similar to the method embodiment, the description is simple, and for the relevant points, reference may be made to the partial description of the method embodiment.
