[0002] Currently, with the increasing popularity of virtual reality / augmented reality (VR / AR) devices, improving the comfort of head-mounted devices and meeting users' needs for extended immersive experiences are becoming important considerations in the design of VR / AR devices. Current head-mounted devices suffer from uneven weight distribution, with weight concentrated on the forehead, leading to significant forward tilting and imbalance, thus reducing the user experience. Summary of the Invention

The main body has a wearing cavity, and a rotating track is formed within the main body, located around the wearing cavity. The rotating ring is rotatably disposed within the rotating track. The output end of the drive assembly is connected to the rotating ring, and the drive assembly is used to drive the rotating ring to rotate.

[0005] Preferably, the drive assembly includes a drive element and an accelerator, the output end of the drive element is connected to the accelerator, the accelerator extends along the axial direction of the rotating ring, the accelerator is located within the rotating track, and the accelerator is rotatably connected to the rotating ring.

[0006] Preferably, there are multiple accelerators, which are spaced apart circumferentially along the rotating ring.

[0007] Preferably, the accelerator surface is provided with wear-resistant texture.

[0008] Preferably, the rotating ring is detachably connected to the main body.

[0009] Preferably, the main body includes a mounting part, a first mounting ring, and a second mounting ring. Both the first mounting ring and the second mounting ring are connected to the mounting part. A rotating track is formed between the first mounting ring and the second mounting ring. The first mounting ring cooperates with the rotating ring to form a mounting groove. The head-mounted device also includes a ball bearing, which can rotate relative to the groove wall of the mounting groove.

[0010] Preferably, the first mounting ring has a first connecting groove; the rotating ring has a second connecting groove on the side near the first mounting ring, the second connecting groove extends circumferentially along the rotating ring, and the second connecting groove cooperates with the first connecting groove to form the mounting groove.

[0011] Preferably, the head-mounted device further includes a sensor disposed on the main body, the sensor being used to detect the rotational speed of the rotating ring.

[0012] In addition, the present invention also provides a control method for controlling the head-mounted device as described above, the control method comprising:

[0013] Obtain the balance state of the head-mounted device;

[0014] When the balance state is unbalanced, the rotating ring is adjusted to run at a preset speed.

[0015] Preferably, the step of adjusting the rotating ring to operate at a preset speed includes:

[0016] The rotational speed of the rotating ring is acquired in real time;

[0017] Calculate the difference between the operating speed and the preset speed;

The drive component drives the rotating ring to rotate, thereby generating angular momentum in the rotating ring.

[0020] After the head-mounted device is powered on, the drive component acts as a power source, driving the rotating ring to rotate at high speed along the rotating track. This causes the rotating ring to generate angular momentum. The high-speed rotating ring has the characteristic of maintaining its rotation axis unchanged. Therefore, it will counteract the tendency of the head-mounted device to be unbalanced and enhance the user's balance experience.

[0021] The head-mounted device of this invention drives a rotating ring to rotate along a rotating track via a drive component, causing the rotating ring to generate angular momentum. The high-speed rotating ring has the characteristic of maintaining its rotation axis unchanged, which will counteract the tendency of the head-mounted device to be unbalanced and enhance the user's balance experience.

[0022] In the control method of this invention, the balance state of the head-mounted device can be obtained. When the balance state is unbalanced, the rotating ring is adjusted to run at a preset speed. The preset speed is a pre-set speed that can better enhance the user's balance experience. The rotating ring runs at the preset speed to counteract the unbalanced trend of the head-mounted device and improve the user's comfort when wearing the head-mounted device.

[0039] This invention provides a head-mounted device and its control method.

[0040] In one embodiment, such as Figures 1 to 2 As shown, the head-mounted device 100 includes a main body 10, a rotating ring 20, and a drive assembly 30. The main body 10 has a wearing cavity 11, and a rotating track 12 is formed inside the main body 10, located on the periphery of the wearing cavity 11. The rotating ring 20 is rotatably disposed in the rotating track 12. The output end of the drive assembly 30 is connected to the rotating ring 20, and the drive assembly 30 is used to drive the rotating ring 20 to rotate.

[0041] The main body 10 has a wearing cavity 11 in the middle, which is inserted into the user's head for wearing. A rotating track 12 is formed inside the main body 10, located around the wearing cavity 11, and a rotating ring 20 is rotatably disposed within the rotating track 12. A drive assembly 30 serves as a power source, and its output end is connected to the rotating ring 20. The drive assembly 30 drives the rotating ring 20 to rotate, thereby generating angular momentum in the rotating ring 20.

[0042] After the head-mounted device 100 is powered on, the drive component 30 acts as a power source to drive the rotating ring 20 to rotate at high speed along the rotating track 12, which causes the rotating ring 20 to generate angular momentum. The high-speed rotating ring 20 has the characteristic of keeping its rotation axis unchanged, thus counteracting the tendency of the head-mounted device 100 to be unbalanced and enhancing the user's balance experience.

[0043] The head-mounted device 100 of the present invention drives the rotating ring 20 to rotate along the rotating track 12 through the driving component 30, so that the rotating ring 20 generates angular momentum. The high-speed rotating ring 20 has the characteristic of keeping its rotation axis unchanged, which will counteract the tendency of the head-mounted device 100 to be unbalanced and enhance the user's balance experience.

[0044] In one embodiment, please refer to the reference Figure 1 and Figure 2 The drive assembly 30 includes a drive element and an accelerator 31. The output end of the drive element is connected to the accelerator 31. The accelerator 31 extends along the axial direction of the rotating ring 20 and is located inside the rotating track 12. The accelerator 31 is rotatably connected to the rotating ring 20.

[0045] The driving component serves as the power source, and its output end is connected to the accelerator 31. The driving component can be a motor, which offers advantages such as high driving efficiency, fast response speed, high control precision, high transmission efficiency, small size, and light weight. Motors can meet the requirements of high-speed and high-precision applications, facilitating integration and lightweight design. The motor's output shaft is connected to the accelerator 31, driving the accelerator 31 to rotate. The accelerator 31 extends axially along the rotating ring 20, meaning it extends vertically. The accelerator 31 is located within the rotating track 12 and is rotatably connected to the rotating ring 20. The driving component drives the accelerator 31 to rotate, which in turn drives the rotating ring 20 to rotate. By adjusting the speed and direction of rotation of the accelerator 31, the speed and direction of rotation of the rotating ring 20 can be adjusted.

[0046] In one embodiment, please refer to the reference Figure 1 There are multiple accelerators 31, which are spaced apart circumferentially along the rotating ring 20.

[0047] The number of accelerators 31 can be multiple, and the multiple accelerators 31 are arranged at intervals along the circumference of the rotating ring 20. By setting multiple accelerators 31, the drive component 30 can drive the rotating ring 20 to rotate more quickly, and the force on the rotating ring 20 is more uniform, so that the rotating ring 20 can rotate more stably.

[0048] In some feasible embodiments, please refer to the references. Figure 1 There are four accelerators 31, which are evenly spaced along the circumference of the rotating ring 20, so that the rotating ring 20 can be evenly stressed. The accelerators 31 can drive the rotating ring 20 to rotate more stably, resulting in a better balance experience for the head-mounted device 100.

[0049] In other embodiments, the number of accelerators 31 can be two, three, or other numbers. The number of accelerators 31 can be flexibly adjusted according to actual needs. The present invention does not limit the number of accelerators 31.

[0050] In one embodiment, please refer to the reference Figure 1 The surface of the accelerator 31 is provided with wear-resistant texture. By providing wear-resistant texture on the surface of the accelerator 31, the wear resistance of the accelerator 31 is improved, avoiding wear caused by long-term contact between the accelerator 31 and the rotating ring 20, which would make it difficult for the accelerator 31 to drive the rotating ring 20 to rotate, thus extending the service life of the accelerator 31 and making the accelerator 31 more convenient to use.

[0051] In some feasible embodiments, the accelerator 31 is made of rubber, which has good wear resistance; the rotating ring 20 is made of wear-resistant metal, so that the rotating ring 20 can better cooperate with the accelerator 31, so that the rotation of the accelerator 31 drives the rotation of the rotating ring 20 to improve the balance experience of the head-mounted device 100.

[0052] In one embodiment, please refer to the reference Figure 2 The rotating ring 20 is detachably connected to the main body 10.

[0053] By setting the rotating ring 20 to be detachably connected to the main body 10, it is convenient to replace the rotating ring 20 when it is worn, making the use of the rotating ring 20 more convenient and improving the flexibility of the rotating ring 20.

[0054] In one embodiment, please refer to the reference Figure 2 and Figure 3The main body 10 includes a mounting part 13, a first mounting ring 14 and a second mounting ring 15. Both the first mounting ring 14 and the second mounting ring 15 are connected to the mounting part 13. A rotating track 12 is formed between the first mounting ring 14 and the second mounting ring 15. The first mounting ring 14 cooperates with the rotating ring 20 to form a mounting groove 60. The head-mounted device 100 also includes a ball bearing 40, which can rotate relative to the groove wall of the mounting groove 60.

[0055] The first mounting ring 14 and the second mounting ring 15 are arranged radially spaced apart along the rotating ring 20. The first mounting ring 14 is located on the side of the rotating ring 20 away from the wearing cavity 11, and the second mounting ring 15 is located on the side of the rotating ring 20 closer to the wearing cavity 11. That is, the second mounting ring 15 and the first mounting ring 14 are located on the inner and outer sides of the rotating ring 20, respectively. A rotating track 12 is formed between the first mounting ring 14 and the second mounting ring 15, thereby forming a rotating track 12 located on the periphery of the wearing cavity 11 within the main body 10. The first mounting ring 14 cooperates with the rotating ring 20 to form a mounting groove 60. The ball bearing 40 can rotate relative to the groove wall of the mounting groove 60. By setting the ball bearing 40 and the mounting groove 60 to cooperate, the ball bearing 40 can limit the rotation of the rotating ring 20, reduce the friction during power transmission, and improve the efficiency of mechanical power transmission, making the rotation of the rotating ring 20 more stable.

[0056] In one embodiment, please refer to the reference Figure 3 The first mounting ring 14 has a first connecting groove 141; the rotating ring 20 has a second connecting groove 21 on the side near the first mounting ring 14. The second connecting groove 21 extends along the circumference of the rotating ring 20, and the second connecting groove 21 cooperates with the first connecting groove 141 to form a mounting groove 60.

[0057] The first connecting groove 141 is formed on the side of the first mounting ring 14 near the rotating ring 20, and the second connecting groove 21 is formed on the side of the rotating ring 20 near the first mounting ring 14. The second connecting groove 21 is disposed opposite to the first connecting groove 141 and extends along the circumference of the rotating ring 20. The second connecting groove 21 and the first connecting groove 141 cooperate to form a mounting groove 60, so that the ball 40 can rotate relative to the rotating ring 20 and the first mounting ring 14.

[0058] In some feasible embodiments, please refer to the references. Figure 4 and Figure 5The head-mounted device 100 includes multiple balls 40, which are evenly spaced along the circumference of the rotating ring 20. The head-mounted device 100 also includes a connector 50, which connects the multiple balls 40. The connector 50 has multiple connecting holes 51, the number of which corresponds to the number of balls 40. Each ball 40 can rotate relative to the wall of a connecting hole 51. By using the connector 50 and having multiple connecting holes 51, the position of the balls 40 is fixed, preventing displacement and making the rotation of the balls 40 more stable, thus improving the safety and reliability of the head-mounted device 100.

[0059] In one embodiment, please refer to the reference Figure 1 The head-mounted device 100 also includes a sensor (not shown) mounted on the main body 10, which is used to detect the rotational speed of the rotating ring 20.

[0060] The sensor is mounted on the main body 10 for installation and fixation. The sensor is also connected to the processor on the main body 10 for communication. The sensor is used to detect the rotation speed of the rotating ring 20 in real time and send the real-time detected rotation speed of the rotating ring 20 to the processor so that the processor can adjust the rotation speed of the rotating ring 20, making the head-mounted device 100 more convenient to use.

[0061] In addition, the present invention also provides a control method for controlling the head-mounted device 100 as described above. The specific structure of the head-mounted device 100 is as described in the above embodiments. Since the control method adopts all the technical solutions of the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0062] Please refer to the reference. Figure 1 The control methods include:

[0063] Step S10: Obtain the balance state of the head-mounted device;

[0064] Step S20: When the balance state is unbalanced, adjust the rotating ring to run at a preset speed.

[0065] The head-mounted device 100 is equipped with an IMU sensor. An IMU (inertial motion unit) is a combination of an accelerometer and a gyroscope sensor. The IMU sensor is used to detect acceleration and angular velocity to represent motion and motion intensity. In the control method of this invention, the balance state of the head-mounted device 100 can be obtained through the IMU sensor. When the balance state is unbalanced, the rotating ring 20 is adjusted to run at a preset speed. The preset speed is a pre-set speed that can better enhance the user's balance experience. The rotating ring 20 runs at the preset speed to counteract the unbalanced tendency of the head-mounted device 100 and improve the user's comfort when wearing the head-mounted device 100.

[0066] In one embodiment, please refer to the reference Figure 2 Step S20 includes:

[0067] Step S21: Obtain the operating speed of the rotating ring in real time;

[0068] The rotating ring 20 is monitored in real time by a sensor mounted on the main body 10 for installation and fixation. The sensor is also connected to the processor on the main body 10 for real-time detection of the rotation speed of the rotating ring 20 and sends the detected rotation speed to the processor so that the processor can adjust the rotation speed of the rotating ring 20, making the head-mounted device 100 more convenient to use.

[0069] Step S22: Calculate the difference between the operating speed and the preset speed;

[0070] Step S23: If the difference between the operating speed and the preset speed is greater than or equal to the preset value, adjust the operating speed according to the difference between the operating speed and the preset speed until the difference between the operating speed and the preset speed is less than the preset value.

[0071] The operating speed is compared with the preset speed, and the difference between the two is calculated. The preset value is the maximum tolerance between the operating speed and the preset speed. If the difference between the operating speed and the preset speed is greater than or equal to the preset value, it indicates that the difference is too large, and the operating speed needs to be further adjusted to bring it closer to the preset speed. If the difference between the operating speed and the preset speed is greater than or equal to the preset value, the operating speed is adjusted according to the difference until the difference is less than the preset value.

[0072] Specifically, if the difference between the operating speed and the preset speed is greater than or equal to the preset value, and the operating speed is greater than the preset speed, then the operating speed of the rotating ring 20 is reduced by adjusting the drive component and accelerator 31, so that the operating speed of the rotating ring 20 is closer to the preset speed. If the difference between the operating speed and the preset speed is greater than or equal to the preset value, and the operating speed is less than the preset speed, then the operating speed of the rotating ring 20 is increased by adjusting the drive component and accelerator 31, so that the operating speed of the rotating ring 20 is closer to the preset speed.

[0073] The above are merely preferred embodiments of the present invention and do not limit the patent scope of the present invention. Any equivalent structural transformations made under the concept of the present invention using the description and drawings of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
