[0021] The following will describe in detail the solutions provided by the embodiments of the present disclosure with reference to the accompanying drawings.

[0022] Combined with the attached Figures 1 to 2 As shown, the present disclosure provides a head-mounted device, including a main body housing 1 and an occlusion housing 2. The aforementioned main body housing 1 serves as the main structure of the head-mounted device. During specific use, a face-attached sponge 6 is connected to the side facing the user to improve the user's comfort. A receiving space (not labeled in the figure) is formed between the main body housing 1 and the occlusion housing 2. The main body housing 1 has a first air outlet 11, and the occlusion housing 2 has a second air inlet 21. A first fan 31 and a host chip (not shown in the figure) on the air flow path driven by the first fan 31 are provided in the receiving space. A air volume adjustment mechanism is provided at the second air inlet 21, and the air volume adjustment mechanism is used to adjust the ventilation area size of the second air inlet 21. The structural position of the aforementioned first air outlet 11 on the main body housing 1 only needs to be adapted to the host chip. Generally speaking, the aforementioned first air outlet 11 serves as an air outlet, and the second air inlet 21 serves as an air inlet. The relatively cold external air flows in through the air inlet and out through the air outlet under the driving action of the first fan 31 to achieve the purpose of dissipating heat from the host chip. At the same time, it can be understood that the face-attached sponge 6 has a breathable property or has breathable holes, and it exists as an inlet for external environmental air. The external environmental air is driven by the first fan 31 and enters the space between the occlusion housing 2 and the user's cheek through the face-attached sponge 6 to dissipate heat from this space, further improving the user's comfort. In this technical solution, by setting the air volume adjustment mechanism to adjust the ventilation area size of the second air inlet 21, the air intake volume can be adjusted, so that the head-mounted device can change the air intake volume according to the heat dissipation requirement and / or the user's comfort requirement, improving the comfort and reliability of the head-mounted device.

[0023] It should be noted that in some feasible embodiments, the aforementioned face-attached sponge 6 can also be made of other flexible materials, such as face-attached silicone, etc., and corresponding breathable holes can be provided separately thereon. Of course, the aforementioned breathable holes can also be constructed on the space where the main body housing 1 protrudes from the occlusion housing 2 close to the user's cheek. To facilitate cleaning the face-attached sponge 6, the face-attached sponge 6 is detachably connected to the main body housing 1.

[0024] As an alternative embodiment, the air volume adjusting mechanism includes a grille plate 41 having a plurality of ventilation holes (not labeled in the figure). The plurality of ventilation holes are arranged at equal intervals in sequence along the sliding direction of the grille plate 41. There are a plurality of second air outlets 21. The number of ventilation holes is the same as the number of the second air outlets 21 and their shape and size are adapted to each other. The grille plate 41 is slidably connected to the shielding housing 2, and the grille plate 41 has a first position for blocking each second air outlet 21 and a second position where each ventilation hole coincides with each second air outlet 21 respectively. The grille plate 41 can be driven to switch between the first position and the second position. In this technical solution, by driving the sliding displacement of the grille plate 41, the switching between its first position and the second position is realized, and further the adjustment of the ventilation volume of the second air outlet 21 from large to small (until blocked) or from small to large is realized. The structure is simple and reliable, and the manufacturing cost is low. At the same time, it should be particularly noted that each ventilation hole and the second air outlet 21 are arranged at equal intervals in sequence along the sliding direction of the grille plate 41, which can realize a large air volume range adjustment in a small space. The sliding switch can save the movement space of the mechanism, especially suitable for the working condition where the head-mounted device has a compact structure.

[0025] The air volume adjusting mechanism further includes a rotary motor 43 (specifically, a stepping motor for example). A gear 431 is connected to the rotating shaft of the rotary motor 43. The grille plate 41 has a rack portion (not labeled in the figure, see Figure 2 shown). The plurality of teeth of the rack portion are arranged at intervals along the sliding direction of the grille plate 41. The gear 431 meshes with the rack portion. By setting corresponding control strategies, the operation of the rotary motor 43 can be controlled, so as to realize the automatic control adjustment of the displacement of the grille plate 41 by the rotary motor 43, especially to meet the heat dissipation requirements of the host chip more real-time and accurately. Optionally, the rotary motor 43 is arranged in the accommodation space, that is, it is arranged on the side away from the user's cheek, preventing damage caused by accidental touch during the user's use, and at the same time having a certain dust-proof and sealing effect.

[0026] In an optional technical solution, the shaft passes through the shielding shell 2 from the accommodating space to the side of the shielding shell 2 away from the accommodating space. At this time, a manual knob 44 is set on the protruding end of the shaft to facilitate the user to adjust the position of the grille plate 41 according to his or her subjective feelings. For example, when the user is using the head-mounted device, the blocked part of the cheek sweats, and the user needs a larger air intake volume. At this time, the manual knob 44 can be manually rotated to increase the ventilation volume of the second air outlet 21, thereby utilizing the larger air volume to dissipate heat and improve user comfort. For another example, a large amount of air intake blows against the user's eyes, causing discomfort such as tears or dry eyes. At this time, the user can also manually rotate the manual knob 44 to reduce the ventilation volume of the second air outlet 21 according to his or her subjective feelings. A smaller air volume can effectively prevent the aforementioned discomfort from occurring. For another example, when the requirements for environmental quietness are high, the user can manually rotate the manual knob 44 to make the ventilation volume of the second air outlet 21 at the maximum position, that is, at the aforementioned second position, thereby reducing the wind resistance of the intake airflow, making the airflow flow smoother, thereby reducing the operating noise of the head-mounted device. Furthermore, an air guide duct 5 is provided between the second air outlet 21 and the first fan 31. The specific structural type of the air guide duct 5 can be various, but it should have a relatively smooth inner air guide wall surface to prevent obstruction to the air flow. In a specific embodiment, it is designed as a structure roughly in the shape of a cone.

[0027] In some embodiments, a second fan (not shown in the figure) is further provided in the accommodation space, and the second fan and the first fan 31 are independently controlled. The provision of the second fan can increase the overall air intake of the head-mounted device, thereby making it easier to meet the heat dissipation requirements of the device and the comfort requirements of the user, that is, the second fan can compensate for the possible insufficient driving force of the single first fan 31. The first fan 31 and the second fan can be completely the same in structure, or of course they can be different, and both can be implemented by a miniature centrifugal fan. Based on the purpose of compact structural design, the first fan 31 and the second fan share the air guide duct 5.

[0028] The present disclosure also provides a control method for the head mounted device as described above, which can be used for the head mounted device provided in the present disclosure, wherein only the first fan 31 is provided in the head mounted device but no second fan is provided, and the control method comprises the following steps:

[0029] When the device is running, control the first fan 31 to operate; obtain the power consumption change state of the device host and the operation state of the manual knob 44; if the operation state of the manual knob 44 is not rotated, control the air volume adjustment mechanism to operate according to the power consumption change state to adjust the ventilation area of the second air outlet 21 until the temperature of the host chip is within the target temperature range. In this technical solution, before controlling the operation of the air volume adjustment mechanism according to the power consumption change state to achieve the matching adjustment of the ventilation area of the second air outlet 21, first determine whether the manual knob 44 is rotated by the user. When the user does not manually rotate the manual knob 44, then adopt an automatic control method to adjust the position of the grille (i.e., the aforementioned grille plate 41) to adjust the ventilation area of the second air outlet 21, change the cooling capacity of the host chip, and then adjust the actual temperature of the host chip, effectively preventing the reduction of the adjustment effect while automatically adjusting when manually intervening in the air volume. Specifically, taking Figure 3 the logic shown as an example for further elaboration: The change in the host power consumption, that is, the aforementioned power consumption change state of the host, is obtained by real-time feedback according to the operation of the device, and it may increase, remain unchanged, or decrease. Generally speaking, when the power consumption remains unchanged or decreases, the corresponding temperature of the host chip will not increase, and the temperature is within the target range. At this time, the control system can maintain the status quo of each relevant component. Of course, during this process, the user can appropriately turn the manual knob 44 according to their subjective feeling of comfort to change the size of the incoming air volume and improve their own use comfort. It should be noted that this manual adjustment process should not be based on the principle that the temperature of the host chip is within the target temperature range; when the host power consumption increases, this means that the host temperature (i.e., the temperature of the host chip) may rise beyond the target temperature range. At this time, first determine whether the user has manually adjusted the position of the grille plate 41. If it is detected that the user is manually adjusting, then wait for the user's manual adjustment and, after the host temperature is within the target temperature range and meets the user's blowing face air volume requirement (based on the user's subjective feeling (such as a refreshing face), and can be adjusted repeatedly), the adjustment ends; when the user does not rotate the manual knob 44, then control the rotary motor 43 of the air volume adjustment mechanism (i.e., Figure 3 the motor in

[0030] to operate, automatically adjust the position of the grille plate 41 relative to the second air outlet 21, and stop the adjustment after detecting that the temperature of the host chip is within the target temperature range.

[0031] Obtain the power consumption change status of the device host; when the power consumption change status is an increase in power consumption, control the first fan 31 to operate at the highest speed, and control the air volume adjustment mechanism to operate according to the relationship between the temperature of the host chip and the target temperature range to adjust the ventilation area of the second air outlet 21, and control the second fan to operate until the temperature of the host chip is within the target temperature range. In this technical solution, when it is detected that the power consumption of the head-mounted device increases, directly control the first fan 31 to operate at the highest speed (i.e., the nominal maximum speed of the first fan 31) to ensure that it provides the air volume required for heat dissipation at full load. Then, adjust the ventilation area of the second air outlet 21 according to the temperature of the host chip and control the second fan to operate, which can simplify the control strategy under high-power consumption conditions, ensure the heat dissipation requirements of the device, and thus ensure the reliable operation of the device. At the same time, on the premise that the first fan 31 operates at full load, by adjusting the speed of the second fan and the ventilation area of the second air outlet 21, the user's comfort during use is taken into account. That is to say, in this technical solution, the heat dissipation requirements of the host chip are given priority, and secondly, the air volume requirements and comfort of the user's cheeks are taken into account. The two fans are controlled in a decoupled manner, and the control is simplified.

[0032] In some embodiments, before controlling the air volume adjustment mechanism to operate, it further includes: obtaining the action status of the manual knob 44. If the action status of the manual knob 44 is not rotated, then control the air volume adjustment mechanism to operate according to the relationship between the temperature of the host chip and the target temperature range to adjust the ventilation area of the second air outlet 21. The design purpose of this technical solution is the same as the corresponding content of only setting the first fan 31 described above, and will not be elaborated here.

[0033] Specifically, taking Figure 4 the shown logic as an example for further elaboration: The cooling fan in the figure is the aforementioned first fan 31, and the face-blowing fan is the aforementioned second fan. When it is detected that the host power consumption increases, at this time, control the cooling fan to operate at full speed. Then, detect the temperature of the host chip. When the temperature of the host chip is still relatively high, control the air volume adjustment mechanism to operate to increase the ventilation area at the second air outlet 21, and at the same time control the face-blowing fan to operate to increase the overall air intake of the device, so as to achieve efficient cooling and heat dissipation of the host chip. During the operation of the face-blowing fan, when the user accepts the corresponding air volume, this automatic air volume adjustment process can be left unintervened until the adjustment is completed. When the user does not accept the corresponding air volume, that is, the comfort brought by the air volume to the user is relatively poor, the user can turn the manual knob 44 according to his own comfort feeling to appropriately adjust the air intake, and this manual adjustment process is based on whether the temperature of the host chip is within the target temperature range.

[0034] The head-mounted device in the embodiments of the present disclosure may be a head-mounted display device, such as a virtual reality device. The present disclosure also proposes an extended reality device, which includes the head-mounted device proposed by the present disclosure. The extended reality device may be, for example, a virtual reality device, an augmented reality device, a mixed reality device, etc. In some embodiments, as Figure 5 shown, users can perform social interactions, entertainment, learning, work, remote work, creation of UGC (User Generated Content), etc. through extended reality devices such as head-mounted displays (HMDs). Users can enter the extended reality space through extended reality devices such as head-mounted glasses and head-mounted helmets, and control their virtual avatars in the extended reality space to perform social interactions, entertainment, learning, remote work, etc. with virtual avatars controlled by other users.

[0035] In one embodiment, in the extended reality space, users can achieve relevant interaction operations through a controller, which can be a handle. For example, users can perform relevant operation controls by operating the buttons on the handle. Of course, in other embodiments, gestures, voice, or multimodal control methods can also be used instead of a controller to control the target object in the extended reality device.

[0036] The extended reality devices described in the embodiments of the present disclosure may include but are not limited to the following types:

[0037] Computer-side extended reality devices, which perform relevant calculations and data output for extended reality functions using the computer side. The externally connected computer-side extended reality devices use the data output by the computer side to achieve the extended reality effect.

[0038] Mobile extended devices, which support setting a mobile terminal (such as a smart phone) in various ways (such as a head-mounted display with a dedicated card slot). Through wired or wireless connection with the mobile terminal, the mobile terminal performs relevant calculations for extended reality functions and outputs data to the mobile extended reality device. For example, watch extended reality videos through the APP of the mobile terminal.

[0039] All-in-one extended reality devices, which have a processor for performing relevant calculations for extended reality functions, and thus have independent extended reality input and output functions. They do not need to be connected to a computer side or a mobile terminal, and have a high degree of freedom of use.

[0040] Of course, the implementation forms of the extended reality devices are not limited to this, and they can be further miniaturized or enlarged according to needs.

[0041] The extended reality device is equipped with sensors for attitude detection (such as nine-axis sensors) to detect the attitude changes of the extended reality device in real time. If a user wears the extended reality device, when the user's head attitude changes, the real-time attitude of the head will be transmitted to the processor, and based on this, the fixation point of the user's line of sight in the extended reality space environment is calculated. According to the fixation point, the images within the user's viewing range (i.e., the virtual field of view) in the three-dimensional model of the extended reality space environment are calculated and displayed on the display screen, providing an immersive experience as if the user is in a real environment.
