Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0019] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0020] Please see Figure 1 , Figure 1This is a schematic diagram of the control handle in some embodiments of this application. The control handle 100 can be communicatively connected to an electronic device to communicate with it, allowing the user to interact with and control the electronic device. The communication connection can be wired, wireless, or a combination thereof. The communication connection can be, for example, a Universal Serial Bus (USB) connection, a Wi-Fi connection, Bluetooth or Bluetooth Low Energy (BLE) connection, an Ethernet connection, a cable connection, a DSL connection, or a cellular connection (e.g., 3G, LTE / 4G, or 5G), or a combination thereof. It is understood that the control handle 100 may also be used independently without a communication connection to an electronic device.

[0021] The control handle 100 can be configured to accommodate either the user's left or right hand. That is, the user can hold the control handle 100 with either their left or right hand. In some scenarios, the user can use either the left or right hand to hold the control handle 100 to interact with electronic devices.

[0022] In some embodiments, the control handle 100 can be configured to accommodate both the user's left and right hands. The control handle 100 can be used by both the left and right hands simultaneously; that is, the left and right hands can hold the control handle 100 together to operate it. In some scenarios, the control handle 100 can be held by both the left and right hands, allowing the user to operate it with their left and / or right hands and interact with electronic devices.

[0023] In some embodiments, one control handle 100 may be configured to correspond to the user's left hand and another control handle 100 may be configured to correspond to the user's right hand, so that the user can hold one adapted control handle 100 with each hand. Of course, the control handle 100 may be configured to be of a universal type, which can be held by the user's left hand or right hand.

[0024] Please see Figure 1 and Figure 2 , Figure 2 for Figure 1 The diagram shows a structural schematic of the control handle 100 from another perspective. The control handle 100 may include a grip body 10 for a user to hold and an extension 20 connected to the grip body 10. The grip body 10 can be held by the user, thus allowing the user to operate the control handle 100. The extension 20 provides a good sense of immersion for the control handle 100 in certain usage scenarios. Furthermore, the extension 20 can cooperate with the grip body 10 to give the control handle 100 a good grip feel.

[0025] In some embodiments, the gripping body 10 may have two ends in the extending direction, namely a first end 101 and a second end 102. In some scenarios, the user may grip the middle portion of the gripping body 10 near the first end 101. Of course, due to limitations or requirements in the structural design of the gripping body 10, the user may also grip other portions of the gripping body 10.

[0026] In some embodiments, a signal input component 11 may be provided on the grip body 10 so that the user can input data or commands to the control handle 100 through the signal input component 11, which can further enable the user to control the control handle 100, and can also further enable the user to control the electronic device through the control handle 100.

[0027] In some embodiments, the signal input component 11 may include electronic devices such as function buttons (e.g., information or data input buttons, power buttons, power buttons, or trigger buttons), joysticks, scroll wheels, touchscreens, or sensors. In some embodiments, the signal input component 11 may include a first input module 111 and a second input module 112. In some embodiments, the first input module 111 may be one or more of various electronic devices such as function buttons (e.g., information or data input buttons, power buttons, power buttons, or trigger buttons), joysticks, scroll wheels, touchscreens, and sensors. In some embodiments, the second input module 112 may be one or more of various electronic devices such as function buttons (e.g., information or data input buttons, power buttons, power buttons, or trigger buttons), joysticks, scroll wheels, touchscreens, and sensors. In some embodiments, the second input module 112 and the first input module 111 are not the same. In some embodiments, the second input module 112 may be a trigger button.

[0028] In some embodiments, the gripping body 10 may have a first mounting surface 103 and a second mounting surface 104 for mounting a signal input component 11. When a user grips the gripping body 10, the signal input component 11 can be operated on the first mounting surface 103 and / or the second mounting surface 104. In some embodiments, the first mounting surface 103 may be provided with a first input module 111, that is, the first input module 111 is disposed on the first mounting surface 103. In some embodiments, the second mounting surface 104 may be provided with a second input module 112, that is, the second input module 112 is disposed on the second mounting surface 104.

[0029] In some embodiments, the first mounting surface 103 and the second mounting surface 104 are respectively disposed on opposite sides of the gripping body 10 in a first direction. In some embodiments, the angle between the first direction and the extending direction of the gripping body 10 may be an acute angle. In some embodiments, the first direction may be perpendicular to the extending direction of the gripping body 10.

[0030] In some scenarios, a user can support the first mounting surface 103 or its vicinity with their fingers to operate the first input module 111, and place their palm near the second mounting surface 104 to operate the second input module 112 with their thumb. Similarly, in some scenarios, a user can support the second mounting surface 104 or its vicinity with their fingers to operate the second input module 112, and place their palm near the first mounting surface 103 to operate the first input module 111 with their thumb.

[0031] The extension 20 may be connected to the gripping body 10, for example, the second end 102. Of course, depending on the limitations or requirements of the structural configuration of the gripping body 10, the extension 20 may also be connected to other parts of the gripping body 10.

[0032] In some embodiments, the extension 20 may extend from the connection point with the gripping body 10, such as the second end 102, so that the control handle 100 provides a good tactile feel in some usage scenarios, and further, its interaction with the gripping body 10 provides a good grip. In some embodiments, the extension 20 may extend spirally about an axis. In some embodiments, the extension 20 may extend to one side in the direction of the axis. In some scenarios, when the user holds the gripping body 10, the extension 20 may extend to wrap around the user's arm, or it may not wrap around the user's arm. In some embodiments, the extension 20 may spiral about an axis and extend to one side in the direction of the axis. In some embodiments, the axis may be parallel to a first direction. Furthermore, the angle between the axis and the extension direction of the gripping body 10 may be an acute angle, or the axis may be perpendicular to the extension direction of the gripping body 10.

[0033] In some embodiments, the shortest distance of the extension 20 from the axis in a cross-section perpendicular to the axis can be configured to gradually increase in the extending direction of the extension 20, thereby improving the appearance of the control handle 100 and making the control handle 100 feel immersive in certain usage scenarios. In some embodiments, the shortest distance of the extension 20 from the axis in a cross-section perpendicular to the axis can also be configured to remain unchanged in the extending direction of the extension 20, thereby improving the appearance of the control handle 100 and making the control handle 100 feel immersive in certain usage scenarios.

[0034] In some embodiments, the cross-sectional area of ​​the extension 20 perpendicular to its extension direction may be configured to gradually decrease in the extension direction of the extension 20, thereby improving the appearance of the control handle 100 and making the control handle 100 feel immersive in certain usage scenarios. In some embodiments, the cross-sectional area of ​​the extension 20 perpendicular to its extension direction may be configured to remain unchanged in the extension direction of the extension 20, thereby improving the appearance of the control handle 100 and making the control handle 100 feel immersive in certain usage scenarios.

[0035] Please see Figure 3 , Figure 3 for Figure 2 The diagram shows a structural schematic of the control handle 100 in some other embodiments. The extension 20 can also extend irregularly in a special manner to enhance the appearance of the control handle 100 and provide a good tactile experience in certain usage scenarios. For example, the extension 20 can extend from the connection point with the gripping body 10, such as the second end 102, providing a good tactile experience in some usage scenarios and further enhancing the grip feel of the control handle 100 in conjunction with the gripping body 10. For example, the extension 20 can extend spirally around an axis. For example, the extension 20 can extend to one side in the direction of the axis. For example, the extension 20 can spiral around an axis and extend to one side in the direction of the axis. For example, the shortest distance of the extension 20 from the axis in a section perpendicular to the axis can be configured to gradually increase, then decrease, and then cycle through increasing and decreasing in the extension direction of the extension 20.

[0036] Please see Figure 4 and Figure 5 , Figure 4 for Figure 2 The schematic diagram shown is a structural representation of the control handle 100 in some other embodiments. Figure 5 for Figure 4The diagram shows a cross-sectional view of the control handle 100 at line V-V. Multiple cavities 201 may be provided inside the extension 20. In some embodiments, the arrangement of cavities 201 can change the internal stress of the extension 20, improving its elastic deformation capability and allowing the control handle 100 to exhibit a good tactile feel in certain usage scenarios. In some embodiments, the arrangement of cavities 201 can change the optical performance of the extension 20, improving its appearance and allowing the control handle 100 to exhibit a good tactile feel in certain usage scenarios. In some embodiments, the multiple cavities 201 may be arranged in the extension direction of the extension 20. In some embodiments, adjacent cavities 201 are spaced apart. In some embodiments, adjacent cavities 201 are spaced apart and connected by a channel to accommodate electronic devices within the extension 20, further enhancing the tactile feel of the control handle 100 in certain usage scenarios.

[0037] Please see Figure 5 The extension 20 may include a light-emitting component 21 disposed within the cavity 201. The light-emitting component 21 emits light outwards from the extension 20, enhancing its appearance and providing a more immersive experience for the control handle 100 in certain usage scenarios. Alternatively, the light-emitting component 21 may be disposed on other parts of the extension 20. In some embodiments, the light-emitting component 21 may emit light that passes through the cavity wall 202 of the cavity 201. In some embodiments, the light-emitting component 21 may be disposed in every cavity 201, or only in some cavities 201.

[0038] In some embodiments, the light-emitting component 21 may include a light guide 211 disposed within the cavity 201 and in contact with the cavity wall 202 of the cavity 201, and a light-emitting diode 212 disposed within the cavity 201. The light-emitting diode 212 can be used to emit light, and the light guide 211 can be used to guide the light emitted by the light-emitting diode 212 into the cavity wall 202 of the cavity 201, so that the light is transmitted to the outside of the extension 20.

[0039] In some embodiments, the light guide 211 may surround the extension direction of the extension 20, so that the light-emitting diode 212 is transmitted in a ring within the light guide 211. In some embodiments, the arrangement of the light guide 211 allows light to be transmitted outward from the extension 20, forming a light spot. This results in the light spot on the extension 20 being a light ring. In some embodiments, the arrangement of the light guide 211 allows light to be transmitted uniformly outward from the extension 20, forming a light spot with uniform overall brightness. It is understood that the user can control the light spot on the extension 20 by controlling the shape and structure of the light guide 211.

[0040] In some embodiments, the light-emitting diode 212 may be an infrared light-emitting diode, but it may also be replaced by other light sources.

[0041] Please see Figure 6 and Figure 7 , Figure 6 for Figure 4 The schematic diagram shown is a structural representation of the control handle 100 in some other embodiments. Figure 7 for Figure 6 The diagram shows a cross-sectional view of the control handle 100 at line VII-VII. The light guide 211 allows light to be transmitted outward from the extension 20, forming a light spot. This makes the light spot on the extension 20 circular.

[0042] Please see Figure 5 The surface of the light guide 211 outside the ring can be in close contact with the cavity wall 202 of the cavity 201. In some embodiments, the surface of the light guide 211 outside the ring can be bonded and fixed to the cavity wall 202 of the cavity 201. In some embodiments, the light-emitting diode 212 can be disposed inside the ring of the light guide 211. Of course, the light-emitting diode 212 can be bonded and fixed to the light guide 211.

[0043] Please see Figure 4 The cavity wall 202 of the cavity 201 is provided with an annular light-transmitting area 203 to further define the light spot on the extension 20. In some embodiments, the annular light-transmitting area 203 surrounds the extension direction of the extension 20. In some embodiments, the light guide 211 is disposed opposite to the annular light-transmitting area 203, so that the light transmitted from the light guide 211 passes through the annular light-transmitting area 203. In some embodiments, the arrangement of the cavity wall 202 of the cavity 201 allows light to be uniformly transmitted outward from the extension 20, forming a light spot with uniform overall brightness. It is understood that the light spot on the extension 20 can be defined by the shape of the annular light-transmitting area 203 and the shape of the light guide 211.

[0044] Please see Figure 6 The cavity wall 202 of the cavity 201 is provided with a circular light-transmitting area 204 to further define the light spot on the extension 20. In some embodiments, the light guide 211 is disposed opposite to the circular light-transmitting area 204, so that the light transmitted through the light guide 211 passes through the circular light-transmitting area 204. It can be understood that the light spot on the extension 20 can be defined by the shape of the circular light-transmitting area 204 and the shape of the light guide 211.

[0045] Understandably, the light spot on the extension 20 can be defined by the shape of the light-transmitting area on the cavity wall 202 of the cavity 201 and the shape of the light guide 211.

[0046] This application next describes an electronic system that may include the control handle 100 described in the above embodiments. Please refer to... Figure 8 , Figure 8This is a schematic diagram of the electronic system in some embodiments of this application. The electronic system 200 may include a near-eye display device 300 worn on the user's head and a control handle 100 that establishes a communication connection with the near-eye display device 300.

[0047] The near-eye display device 300 can be worn directly on the user's head to achieve virtual reality or augmented reality functions in front of the user's eyes. The near-eye display device 300 can be equipped with display components, optics, sensors, a processor, and a battery. The control handle 100 can communicate with the near-eye display device 300, allowing the user to interact with and control the near-eye display device 300. It is understood that the near-eye display device 300 can be the electronic device described in the above embodiments. Of course, the near-eye display device 300 can also be replaced by an electronic device worn on other parts of the user's body and establishing a communication connection with the control handle 100. Furthermore, the near-eye display device 300 can also be replaced by other electronic devices that do not need to be worn on the user's body but establish a communication connection with the control handle 100.

[0048] The near-eye display device 300 can be an augmented reality or virtual reality device, such as augmented reality or virtual reality glasses. Of course, the near-eye display device 300 can also be other devices that need to be worn on the head, such as devices with lighting or camera functions that can be worn on the head, which will not be elaborated here. The following detailed explanation uses the near-eye display device 300 as an example of augmented reality or virtual reality glasses.

[0049] In examples of augmented reality or virtual reality glasses, the near-eye display device 300 can be configured to transmit and receive data from an external processing device via a signal connection, which can be a wired connection, a wireless connection, or a combination thereof. However, in other cases, the near-eye display device 300 can be used as a standalone device, i.e., data processing is performed within the near-eye display device 300 itself. The signal connection can be configured to carry any kind of data, such as image data (e.g., still images and / or fully moving video, including 2D and 3D images), audio, multimedia, voice, and / or any other type of data. The external processing device can be, for example, a game console, a personal computer, a tablet computer, a smartphone, or other type of processing device. The signal connection can be, for example, a Universal Serial Bus (USB) connection, a Wi-Fi connection, a Bluetooth or Bluetooth Low Energy (BLE) connection, an Ethernet connection, a cable connection, a DSL connection, a cellular connection (e.g., 3G, LTE / 4G, or 5G), or a combination thereof. Additionally, the external processing device can communicate with one or more other external processing devices via a network, which may be, for example, a local area network (LAN), a wide area network (WAN), an intranet, a metropolitan area network (MAN), the Internet, or a combination thereof.

[0050] The near-eye display device 300 may house display components, optics, sensors, and processors. In an example of augmented reality or virtual reality glasses, the display components are designed to, for example, function as virtual reality glasses by projecting light into the user's eyes, or as augmented reality glasses by projecting light into the user's eyes to overlay an image onto the user's view of their real-world environment. The near-eye display device 300 may also include an ambient light sensor and an electronic circuitry system to control at least some of the aforementioned components and perform associated data processing functions. The electronic circuitry system may include, for example, one or more processors and one or more memories.

[0052] The processor 3001 can process data and commands related to the normal operation of the near-eye display device 300 and / or the control handle 100, and can also be used to control the near-eye display device 300 and / or the control handle 100, or to enable the control handle 100 to control the near-eye display device 300, or vice versa. The first communication module 3002 establishes a communication connection with the control handle 100 to transmit data and commands between the near-eye display device 300 and the control handle 100. In some embodiments, the first communication module 3002 can be a Bluetooth module to enable Bluetooth or Bluetooth Low Energy (BLE) connection between the near-eye display device 300 and the control handle 100; of course, the first communication module 3002 can also be other types. In some embodiments, the first communication module 3002 can establish a communication connection and communicate with the control handle 100 under the control of the processor 3001. The camera module 3003 can be used to acquire images outside the near-eye display device 300. In some embodiments, the camera module 3003 can be used to acquire images to enable augmented reality or virtual reality for the near-eye display device 300. In some embodiments, the camera module 3003 can be used to acquire images to enable obstacle avoidance and / or alert functions for the near-eye display device 300. In some embodiments, the camera module 3003 can be used to acquire images of the control handle 100 to enable the near-eye display device 300 to determine the attitude and position of the control handle 100. In some embodiments, the camera module 3003 may include a fisheye camera, and of course, may also include others. In some embodiments, the camera module 3003 can acquire images of the control handle 100 under the control of the processor 3001.

[0053] Please see Figure 9The control handle 100 may include a second communication module 1001 communicatively connected to the near-eye display device 300 (e.g., a first communication module 3002), a light-emitting component 21 electrically connected to the second communication module 1001, and a sensor 1002 electrically connected to the second communication module 1001. The second communication module 1001 can transmit data, commands, etc., to the near-eye display device 300 (e.g., the first communication module 3002). In some embodiments, the second communication module 1001 can transmit commands to control the control handle 100 to the near-eye display device 300 (e.g., the first communication module 3002). In some embodiments, the second communication module 1001, in cooperation with the first communication module 3002, can transmit commands to control the control handle 100. In some embodiments, the second communication module 1001 can transmit commands to control the light-emitting component 21 to the near-eye display device 300 (e.g., the first communication module 3002). In some embodiments, the second communication module 1001, in cooperation with the first communication module 3002, can transmit commands to control the light-emitting component 21 to the control handle 100. In some embodiments, the second communication module 1001 can transmit data output by the sensor 1002 to the near-eye display device 300, such as the first communication module 3002. In some embodiments, the second communication module 1001 and the first communication module 3002 cooperate to transmit data output by the sensor 1002 to the near-eye display device 300. In some embodiments, the second communication module 1001 can transmit commands to control the near-eye display device 300, such as the first communication module 3002. In some embodiments, the second communication module 1001 and the first communication module 3002 cooperate to transmit commands to control the near-eye display device 300. In some embodiments, the near-eye display device 300, such as the camera module 3003, captures an image of the light emitted by the light-emitting component 21 on the control handle 100 (e.g., a light spot on the extension 20). In some embodiments, the near-eye display device 300, such as the processor 3001, can determine the posture and position of the control handle 100 based on the light emitted by the light-emitting component 21. In some embodiments, the near-eye display device 300, such as the processor 3001, can determine the attitude and position of the control handle 100 based on the light emitted by the light-emitting component 21 and the data output by the sensor 1002.

[0054] In some embodiments, sensor 1002 may be an inertial measurement unit (IMU). Of course, it may also be other sensors such as accelerometers, gyroscopes, or other sensors that measure attitude angles (or angular rates) and acceleration.

[0055] Understandably, since the near-eye display device 300 is an electronic device, other electronic devices can be used to replace it, allowing these other electronic devices to interact with the control handle 100 through the interaction between the near-eye display device 300 and the control handle 100. These electronic devices include, but are not limited to, cellular phones, smartphones, other wireless communication devices, personal digital assistants, audio players, other media players, music recorders, video recorders, cameras, other media recorders, radios, medical devices, calculators, programmable remote controls, pagers, netbooks, personal digital assistants (PDAs), portable multimedia players (PMPs), Moving Image Experts Group (MPEG-1 or MPEG-2), Audio Layer 3 (MP3) players, portable medical devices, and digital cameras and their combinations.

Sensors 1002 can be mounted on the grip body 10 and / or the extension 20. The coordinated design of the grip body 10 and the extension 20 provides the control handle 100 with a comfortable grip and enhances immersion in certain usage scenarios.

[0057] In some embodiments, a sensor 1002 may be disposed inside the gripping body 10. Of course, the sensor 1002 may also be disposed inside the extension 20.

[0058] The light-emitting component 21 provided on the extension 20 facilitates the near-eye display device 300 in determining the attitude and position of the control handle 100. In some embodiments, the light-emitting component 21 is used to emit light outward from the extension 20, and the light and data are used to cooperate in enabling the near-eye display device 300 to determine the attitude and position of the control handle 100.
