Description

Technical Field

[0001] Embodiments of the present disclosure relate to the technical field of virtual reality devices, and more specifically, to a head-mounted display device and a control method for a head-mounted display device. Background Art

[0002] At present, on the one hand, the high integration of head-mounted VR (Virtual Reality) devices leads to serious heat generation of head-mounted VR devices; on the other hand, in order to prevent external light from affecting the user experience of the product, when experiencing a head-mounted VR device, the head-mounted VR device needs to be closely attached to the user's face. In this way, when the user uses or experiences a sports scene in a hot environment, the user will produce a large amount of sweat and water vapor, which will affect the user experience.

[0059] <Embodiment of the head-mounted display device>

[0060] Please refer to Figure 1 , which is a schematic structural diagram of a head-mounted display device provided by an embodiment of the present application. As Figure 1 and 2 shown, the head-mounted display device 10 includes a device body 11, a bottom shell 12, an adsorption layer 13 and a heating sheet 14. The bottom shell 12 is disposed on one side of the device body 11. The bottom shell 12 has a first side surface and a second side surface. An exhaust groove 121 is formed in the first side surface, and an exhaust hole 122 is formed in the second side surface. The exhaust hole 122 is communicated with the exhaust groove 121. Among them, the first side surface is the side surface for contacting the wearer. The adsorption layer 13 is disposed in the exhaust groove 121. The heating sheet 14 is located in the exhaust groove 121 and is disposed close to the exhaust hole 122.

[0061] In this embodiment, as Figure 1As shown, the bottom shell 12 is disposed on the side of the device body 11 that contacts the wearer. The bottom shell 12 has a first side and a second side that are adjacent to each other. The first side can be the side that contacts the wearer, that is, the side opposite to the device body. The second side can be the outer peripheral surface of the shell 12.

[0062] In this embodiment, the exhaust groove 121 is disposed near the edge of the bottom shell 12, and the exhaust groove 121 is used to place the adsorption layer. When the head-mounted display device 10 is in use, the adsorption layer 13 near the edge of the bottom shell 12 is closely attached to the wearer's face to prevent external light from affecting the user experience of the product. Exemplarily, the depth of the exhaust groove 121 can be uniform. Exemplarily, the depth of the part of the exhaust groove 121 communicating with the exhaust hole 122 is greater than that of other parts.

[0063] In this embodiment, one exhaust groove can be opened on the first side of the bottom shell 12. Multiple exhaust grooves can also be opened on the second side of the bottom shell 12.

[0064] In one embodiment, as Figure 1 shown, the exhaust groove 121 can be annular. Exemplarily, the exhaust groove 121 is disposed near the edge of the bottom shell 12, and the shape of the exhaust groove 121 is consistent with the outer contour of the bottom shell 12.

[0065] In one embodiment, the exhaust groove 121 can include at least two exhaust groove segments, and the at least two exhaust groove segments are arranged in an annular shape. One exhaust hole, one adsorption layer, and one heating sheet are correspondingly arranged for one exhaust groove segment.

[0066] Exemplarily, as Figure 5 shown, the exhaust groove includes two exhaust groove segments, namely an exhaust groove segment 121a and an exhaust groove segment 121b, and the two exhaust groove segments can form an annular shape. Two exhaust holes 122 are correspondingly opened on the second side of the shell 12, and the two exhaust holes 122 are respectively communicated with the two exhaust groove segments. A heating sheet is also arranged in each exhaust groove segment, and the heating sheet is located near the exhaust hole.

[0067] In this embodiment, the exhaust hole 122 is located on the second side of the bottom shell 12 and is communicated with the exhaust groove 121. That is, when the head-mounted display device 10 is in use, a closed space is formed between the bottom shell 12 and the wearer. The exhaust hole 122 is located outside the closed space, and the exhaust hole 122 can communicate the exhaust groove 121 with the outside to discharge the vaporized sweat.

[0068] In this embodiment, one exhaust hole 122 can be opened on the second side of the bottom shell 12, or multiple exhaust holes 122 can be opened. It can be understood here that multiple exhaust holes 122 can correspond to one exhaust groove 121. Exemplarily, as Figure 2As shown, two exhaust holes 122 are formed in the second side surface of the bottom case 12. The two exhaust holes 122 are symmetrically arranged. One exhaust hole 122 is arranged on the left side of the bottom case 12, and the other exhaust hole 122 is arranged on the right side of the bottom case 12. The multiple exhaust holes 122 can also respectively correspond to different exhaust groove segments. Exemplarily, as Figure 5 shown, two exhaust holes 122 are formed in the second side surface of the bottom case 12. The two exhaust holes 122 are symmetrically arranged. One exhaust hole 122 is arranged on the left side of the bottom case 12 and communicates with the left exhaust groove segment 121a, and the other exhaust hole 122 is arranged on the right side of the bottom case 12 and communicates with the right exhaust groove segment 121b.

[0069] It should be noted here that the exhaust hole 122 can be composed of multiple sub-air holes. For example, as Figure 3 and Figure 4 shown, an annular array composed of multiple sub-air holes.

[0070] It can be understood that the bottom case 12 is also provided with other structures for cooperating with the device body, and the embodiments of the present disclosure do not limit this.

[0071] In this embodiment, the adsorption layer 13 is arranged in the exhaust groove 121 of the bottom case 12, that is, the adsorption layer 13 fills the exhaust groove 121. The structure of the adsorption layer 13 is adapted to the structure of the exhaust groove 121.

[0072] In one embodiment, when the exhaust groove is annular, the adsorption layer 13 includes an annular portion 131 and a protruding portion 132. The annular portion 131 is arranged in the annular exhaust groove 121, and the protruding portion 132 is connected to the annular portion 131 and is correspondingly arranged with the exhaust hole 122.

[0073] Exemplarily, as Figure 3 and 4 shown, the protruding portion 132 of the adsorption layer 13 is arranged on the lower side of the annular portion 131. That is to say, when the adsorption layer 13 is placed in the exhaust groove 121 of the bottom case 12, the upper surface of the annular portion 131 of the adsorption layer 13 is flush with the bottom case 12 or slightly higher than the first side surface of the bottom case 12 to closely fit the wearer's face. The protruding portion 132 of the adsorption layer 13 is located below the annular portion 131 and is correspondingly arranged with the exhaust hole 122, that is, the protruding portion 132 can block the exhaust hole 122. In this way, the arrangement of the protruding portion 132 of the adsorption layer 13 can increase the exhaust area, so that the water vapor generated after the sweat is heated can be quickly discharged, further improving the user experience.

[0074] It should be noted here that the number of the protruding portions 132 can be set according to the number of the exhaust holes 122. For example, as Figure 3 and 4As shown, the adsorption layer 13 is provided with two protruding parts 132, and the two protruding parts 132 are respectively arranged corresponding to the two exhaust holes 122 of the bottom case 12.

[0075] It should also be noted here that in the case where the exhaust groove includes at least two exhaust groove segments, an adsorption layer is provided for each exhaust groove segment.

[0076] In this embodiment, the adsorption layer 13 may have a fibrous structure for adsorbing the sweat generated by the wearer to prevent the sweat from turning into water vapor, which may affect the user experience of the product, and to avoid leaving sweat stains on the bottom case when the head-mounted display device is used for a long time.

[0077] In one embodiment, the adsorption layer 13 may be a structure formed by injection molding to reach a fibrous state. Optionally, the adsorption layer 13 may be a bamboo charcoal fiber layer, and the embodiments of the present disclosure do not limit this.

[0078] In this embodiment, the adsorption layer 13 is made of bamboo charcoal fiber, which can reduce the cost. Moreover, the user can replace the adsorption layer 13 regularly according to needs to ensure the sweat absorption effect of the adsorption layer 13, and the maintenance cost is relatively low.

[0079] In this embodiment, the heating sheet 14 is used to heat the sweat adsorbed by the adsorption layer 13, so that the sweat is vaporized by heat and discharged from the exhaust hole 122. The heating sheet 14 is located in the exhaust groove 121 and is arranged close to the exhaust hole 122. Exemplarily, as Figure 4 shown, the heating sheet 14 is arranged in the exhaust groove and is located below the adsorption layer 13. More specifically, the heating sheet 14 is arranged below the protruding part 132 of the adsorption layer 13 ( Figure 4 in the case where the opening of the exhaust groove faces downward and the heating layer 14 is located above the adsorption layer 13), that is, the heating sheet 14 and the adsorption layer 13 are stacked in the exhaust groove, and the adsorption layer 13 is located on the outside. In this way, the heating sheet 14 heats the adsorption layer 13 near the exhaust hole 122, so that the sweat adsorbed there is vaporized by heat acceleration and discharged through the exhaust hole 122. At this time, the moisture content of the adsorption layer 13 near the exhaust hole 122 decreases, and the moisture content of the adsorption layer 13 near the exhaust hole 122 is always lower than other parts of the adsorption layer 13, and the sweat adsorbed by the adsorption layer 13, that is, the moisture of the adsorption layer 13, will always flow towards the exhaust hole 122.

[0080] It should be noted here that the number of the heating sheets 14 can be set according to the number of the exhaust holes 122. For example, as Figure 3 and 4As shown in the figure, the head-mounted display device 10 includes two heating sheets 14. One heating sheet 14 is disposed near the exhaust hole 122 on the left side of the bottom case 122, and the other heating sheet 14 is disposed near the exhaust hole 122 on the right side of the bottom case 122. In this embodiment, increasing the number of exhaust holes and heating sheets can shorten the discharge path of the sweat or moisture adsorbed by the adsorption layer, so that the sweat or moisture adsorbed by the adsorption layer is quickly discharged.

[0081] It should also be noted here that in the case where the exhaust groove includes at least two exhaust groove segments, each exhaust groove segment is provided with a heating sheet.

[0082] In one embodiment, the heating sheet 14 can be a graphite heating sheet, and the heating sheet 14 can also be graphene.

[0083] In this embodiment, by providing a heating sheet near the exhaust hole, the sweat adsorbed by the adsorption layer near the exhaust hole is quickly vaporized and discharged by heating, and the moisture content of the adsorption layer near the exhaust hole is always lower than other parts of the adsorption layer, so that the moisture of the adsorption layer will always flow toward the exhaust hole, thereby keeping the adsorption layer dry, avoiding the discomfort caused by a large amount of sweat of the wearer, and improving the user experience. In addition, using a graphite heating sheet for the heating sheet can save space.

[0084] In one embodiment, as Figure 6 shown, the head-mounted display device 10 further includes a sensor 15 and a control chip 16. The sensor 15 is disposed inside the device body 11, and the sensor 15 is used to collect a first detection value, wherein the first detection value is used to measure the sweating degree of the wearer of the head-mounted display device. The control chip 16 is disposed inside the device body 11, and the control chip 16 is respectively connected to the sensor 15 and the heating sheet 14. The control chip 16 is used to obtain the first detection value detected by the sensor 15 and control the heating sheet 14 to work according to the first detection value.

[0085] In this embodiment, the head-mounted display device 10 further includes a sensor, which is used to detect the sweating degree of the wearer, or to detect the moisture content of the enclosed space between the wearer and the bottom case. The first detection value can be a parameter value reflecting the sweating degree of the wearer of the head-mounted display device. It can be understood that the head-mounted display device can be provided with one sensor or multiple sensors.

[0086] In this embodiment, the control chip is respectively connected to the sensor and the heating sheet to obtain the first detection value collected by the sensor and control the heating sheet to work according to the first detection value. In this way, when the wearer produces a large amount of sweat, the adsorption layer is heated to quickly discharge a large amount of sweat, which can improve the working efficiency of the heating sheet and reduce the device power consumption.

[0087] In a more specific example, the sensor 15 is a sweat sensor, and the first detection value is the amount of sweat of the wearer. The control chip 16 is configured to obtain the amount of sweat of the wearer detected by the sweat sensor, and control the heating sheet 14 to heat up when the amount of sweat is greater than or equal to a set first threshold.

[0088] In this embodiment, the sweat sensor is disposed within the device body 11. The probe of the sweat sensor is close to the skin of the wearer and is used to detect the amount of sweat of the wearer. Exemplarily, the sweat sensor may be a flexible sweat sensor or a non-flexible sweat sensor, and the embodiments of the present disclosure do not limit this.

[0089] The first threshold can be used to measure whether the sweat produced by the wearer is excessive. When the amount of sweat of the wearer detected by the sweat sensor is greater than or equal to the first threshold, it indicates that the wearer produces a large amount of sweat, and it is considered that the water content adsorbed by the adsorption layer 13 reaches a certain level, and the adsorption capacity of the adsorption layer 13 is close to saturation. At this time, the control chip controls the heating sheet to heat up to timely discharge the moisture in the adsorption layer, so that the adsorption layer and the closed space between the wearer and the bottom shell remain dry. When the amount of sweat of the wearer detected by the sweat sensor is less than the first threshold, it indicates that the wearer produces a small amount of sweat, and it is considered that the water content adsorbed by the adsorption layer 13 is low, and the adsorption capacity of the adsorption layer 13 is not close to saturation. At this time, there is no need for the heating sheet to work, and the small amount of sweat can be adsorbed by the adsorption layer. It should be noted here that the first threshold can be set by those skilled in the art, and the embodiments of the present disclosure do not limit this.

[0090] Next, taking the sensor as a sweat sensor as an example, the working principle of the bottom shell of the head-mounted display device will be described. As Figure 7As shown, during the use of the head-mounted display device, when a large amount of sweat is discharged from the skin surface of the wearer, it will be absorbed by the adsorption layer 13 on the bottom case 12 through capillary action. As the sweat stains increase, the sweat will flow towards the dry part of the adsorption layer 13. At the same time, the sweat sensor can collect the sweat volume of the wearer's skin in real time and send the collected sweat volume to the control chip. When the control chip detects that the sweat volume of the wearer's skin is greater than or equal to the first threshold, that is, when the moisture content of the adsorption layer 13 reaches a certain level and the adsorption capacity of the adsorption layer 13 is close to saturation, the control chip controls the heating sheet 14 to heat the adsorption layer 13 near the exhaust hole 122, so that the moisture in the adsorption layer at this place is heated and accelerated to vaporize and is discharged through the exhaust hole 122, reducing the moisture content of the adsorption layer 13 near the exhaust hole 122. The moisture content of the adsorption layer 13 near the exhaust hole 122 is always lower than other parts of the adsorption layer 13, further causing the moisture in the adsorption layer 13 to always flow towards the exhaust hole 122, that is, the moisture in the adsorption layer 13 flows towards the exhaust holes 122 on both sides and is discharged according to the illustrated moisture flow direction. When the control chip detects that the sweat volume of the wearer's skin is less than the first threshold, it controls the heating sheet 14 to stop heating.

[0091] In this embodiment, the sweat sensor is used to monitor the sweat volume of the wearer in real time, and when the sweat volume is greater than or equal to the first threshold, the heating sheet is controlled to heat. In this way, the detection accuracy can be improved, so that the moisture in the adsorption layer can be discharged in time, avoiding discomfort caused to the user by a large amount of sweat generated by the wearer.

[0092] In another more specific example, the sensor 15 is a humidity sensor, and the first detection value is the humidity value of the area between the device body and the wearer; the control chip 16 is used to obtain the humidity value of the area between the device body and the wearer detected by the humidity sensor, and when the humidity value is greater than or equal to the set second threshold, it controls the heating sheet 14 to heat.

[0093] In this embodiment, the humidity sensor is arranged inside the device body 11, and the probe of the humidity sensor is located in the enclosed space between the wearer and the bottom case, and is used to detect the humidity value of the area between the device body and the wearer. The humidity value of the area between the device body and the wearer can reflect the moisture content of the adsorption layer. The higher the humidity value of the area between the device body and the wearer, the more sweat the wearer generates, that is, the more moisture content the adsorption layer adsorbs. The lower the humidity value of the area between the device body and the wearer, the less sweat the wearer generates, that is, the less moisture content the adsorption layer adsorbs.

[0094] The second threshold can be used to measure whether the humidity value in the area between the device body and the wearer is too high. When the humidity value is greater than or equal to the set second threshold, it indicates that the wearer produces a large amount of sweat, is prone to generating water vapor, and the water content adsorbed by the adsorption layer 13 reaches a certain level, and the adsorption capacity of the adsorption layer 13 is close to saturation. At this time, the control chip controls the heating sheet to heat up to timely discharge the moisture in the adsorption layer, so that the adsorption layer and the enclosed space between the wearer and the bottom shell remain dry. When the humidity value is less than the set second threshold, it indicates that the wearer produces a small amount of sweat, and it is considered that the water content adsorbed by the adsorption layer 13 is relatively low, and the adsorption capacity of the adsorption layer 13 is not close to saturation. At this time, there is no need for the heating sheet to work, and the small amount of sweat can be adsorbed by the adsorption layer. It should be noted here that the second threshold can be set by those skilled in the art, and the embodiments of the present disclosure do not limit this.

[0095] Taking the sensor as a humidity sensor as an example, the working principle of the bottom shell of the head-mounted display device will be described below. As Figure 7 shown, during the use of the head-mounted display device, when a large amount of sweat is discharged from the wearer's skin surface, it will be absorbed by the adsorption layer 13 on the bottom shell 12 through the capillary phenomenon. As the sweat stains increase, the sweat will flow towards the dry part of the adsorption layer 13. At the same time, the humidity sensor can collect the humidity value of the enclosed space between the wearer and the bottom shell in real time and send the collected humidity value to the control chip. When the control chip detects that the humidity value is greater than or equal to the second threshold, that is, when the water content of the adsorption layer 13 reaches a certain level and the adsorption capacity of the adsorption layer 13 is close to saturation, the control chip controls the heating sheet 14 to heat the adsorption layer 13 near the exhaust hole 122, so that the moisture in the adsorption layer at this place is heated and accelerated to vaporize and is discharged through the exhaust hole 122, so that the water content of the adsorption layer 13 near the exhaust hole 122 is reduced, and the water content of the adsorption layer 13 near the exhaust hole 122 is always lower than other parts of the adsorption layer 13, further causing the moisture in the adsorption layer 13 to always flow towards the exhaust hole 122, that is, the moisture in the adsorption layer 13 flows towards the exhaust holes 122 on both sides in the direction of the moisture flow shown in the figure and is discharged. When the control chip detects that the humidity value of the wearer's skin is less than the second threshold, the control chip controls the heating sheet 14 to stop heating.

[0096] In this embodiment, a humidity sensor is used to monitor the humidity value of the enclosed space between the wearer and the bottom shell in real time, and when the humidity value is greater than or equal to the second threshold, the heating sheet is controlled to heat up. In this way, the detection accuracy can be improved to timely discharge the moisture in the adsorption layer and avoid the discomfort caused to the user by the large amount of sweat produced by the wearer.

[0097] In one embodiment, the bottom shell 12 is detachably connected to the device body 11. Exemplarily, the bottom shell 12 and the device body 11 are connected by a snap connection. Exemplarily, the bottom shell 12 and the device body 11 are connected by a magnetic attraction method.

[0098] In this embodiment, the bottom shell is detachably connected to the device body. When there is sweat or dirt on the bottom shell, the bottom shell can be detached and cleaned, which is more convenient to use. In addition, the bottom shell can also be replaced, which can extend the service life of the head-mounted display device and reduce the maintenance cost.

[0099] According to an embodiment of the present disclosure, during the use of the head-mounted display device, when the wearer produces a large amount of sweat, the adsorption layer can adsorb the sweat produced by the wearer, and the heating sheet can heat the adsorption layer near the exhaust hole. The moisture in the adsorption layer at this place is heated and accelerated to vaporize and discharge, so that the moisture content of the adsorption layer near the exhaust hole is always lower than other parts of the adsorption layer. Further, the moisture in the adsorption layer will always flow towards the exhaust hole and be discharged, so that the sweat produced by the wearer is discharged in time. In this way, it is possible to avoid the generation of water vapor in the enclosed space between the wearer and the head-mounted display device, and it is possible to keep the adsorption layer dry, avoiding the discomfort caused to the user by the large amount of sweat produced by the wearer, so as to improve the user experience.

[0100] <Method Embodiment>

[0101] Figure 8 The flowchart of the control method of the head-mounted display device according to an embodiment of the present disclosure is shown. The control method of the head-mounted display device is applied to the head-mounted display device described in the above embodiment. As Figure 8 shown, the control method of the head-mounted display device provided in this embodiment may include the following steps S8100 to S8200.

[0102] Step S8100, obtaining a first detection value collected by a sensor, where the first detection value is used to measure the sweating degree of the wearer of the head-mounted display device.

[0103] In this embodiment, the sensor is used to detect the sweating degree of the wearer, or to detect the moisture content in the enclosed space between the wearer and the bottom shell. The first detection value may be a parameter value reflecting the sweating degree of the wearer of the head-mounted display device.

[0104] Step S8200, controlling the heating sheet of the head-mounted display device to work according to the first detection value.

[0105] In one embodiment, the sensor is a sweat sensor, and the obtaining of the first detection value collected by the sensor may further include: obtaining the amount of sweat of the wearer collected by the sweat sensor; the controlling the heating sheet of the head-mounted display device to work according to the first detection value may further include: when the amount of sweat is greater than or equal to a set first threshold, controlling the heating sheet to heat up.

[0106] In this embodiment, the sweat sensor is disposed inside the device body, and the probe of the sweat sensor is close to the skin of the wearer for detecting the amount of sweat of the wearer. Exemplarily, the sweat sensor may be a flexible sweat sensor or a non-flexible sweat sensor, and the embodiments of the present disclosure do not limit this.

[0107] The first threshold may be used to measure whether the sweat produced by the wearer is excessive. When the amount of sweat of the wearer detected by the sweat sensor is greater than or equal to the first threshold, it indicates that the wearer produces a large amount of sweat, and it is considered that the moisture content adsorbed by the adsorption layer reaches a certain level and the adsorption capacity of the adsorption layer is close to saturation. At this time, the control chip controls the heating sheet to heat up to timely discharge the moisture of the adsorption layer, so that the closed space between the adsorption layer, the wearer and the bottom case remains dry. When the amount of sweat of the wearer detected by the sweat sensor is less than the first threshold, it indicates that the wearer produces a small amount of sweat, and it is considered that the moisture content adsorbed by the adsorption layer is low and the adsorption capacity of the adsorption layer is not close to saturation. At this time, there is no need for the heating sheet to work, and the small amount of sweat can be adsorbed by the adsorption layer. It should be noted here that the first threshold may be set by those skilled in the art, and the embodiments of the present disclosure do not limit this.

[0108] In specific implementation, during the use of the head-mounted display device, when a large amount of sweat is discharged from the skin surface of the wearer, it will be absorbed by the adsorption layer on the bottom case through capillary action. As the sweat stains increase, the sweat will flow towards the dry part of the adsorption layer. At the same time, the sweat sensor can collect the amount of sweat on the skin of the wearer in real time and send the collected amount of sweat to the control chip. When the control chip detects that the amount of sweat on the skin of the wearer is greater than or equal to the first threshold, that is, when the moisture content of the adsorption layer reaches a certain level and the adsorption capacity of the adsorption layer is close to saturation, the control chip controls the heating sheet to heat the adsorption layer near the exhaust hole, so that the moisture of the adsorption layer at this place is heated and accelerated to vaporize and discharged through the exhaust hole, so that the moisture content of the adsorption layer near the exhaust hole is reduced, and the moisture content of the adsorption layer near the exhaust hole is always lower than other parts of the adsorption layer, further causing the moisture of the adsorption layer to always flow towards the exhaust hole, that is, the moisture of the adsorption layer flows towards the exhaust holes on both sides and is discharged. When the control chip detects that the amount of sweat on the skin of the wearer is less than the first threshold, it controls the heating sheet to stop heating.

[0109] In this embodiment, a sweat sensor is used to monitor the amount of sweat of the wearer in real time. When the amount of sweat is greater than or equal to the first threshold, the heating sheet is controlled to heat up. In this way, the detection accuracy can be improved to timely drain the moisture in the adsorption layer and avoid discomfort caused to the user by a large amount of sweat produced by the wearer.

[0110] In one embodiment, the sensor is a humidity sensor. The obtaining of the first detection value collected by the sensor may further include: obtaining the humidity value of the area between the device body and the wearer collected by the humidity sensor; the controlling of the heating sheet of the head-mounted display device to work according to the first detection value may further include: controlling the heating sheet to heat up when the humidity value is greater than or equal to the set second threshold.

[0111] In this embodiment, the humidity sensor is disposed inside the device body, and the probe of the humidity sensor is located in the sealed space between the wearer and the bottom shell for detecting the humidity value of the area between the device body and the wearer. The humidity value of the area between the device body and the wearer can reflect the moisture content of the adsorption layer. The higher the humidity value of the area between the device body and the wearer, the more sweat the wearer produces, that is, the more moisture content the adsorption layer adsorbs. The lower the humidity value of the area between the device body and the wearer, the less sweat the wearer produces, that is, the less moisture content the adsorption layer adsorbs.

[0112] The second threshold can be used to measure whether the humidity value of the area between the device body and the wearer is too high. When the humidity value is greater than or equal to the set second threshold, it indicates that the wearer produces a large amount of sweat, is prone to generate water vapor, and the moisture content adsorbed by the adsorption layer reaches a certain level, and the adsorption capacity of the adsorption layer is close to saturation. At this time, the control chip controls the heating sheet to heat up to timely drain the moisture in the adsorption layer, so that the adsorption layer and the sealed space between the wearer and the bottom shell remain dry. When the humidity value is less than the set second threshold, it indicates that the wearer produces a small amount of sweat, and it is considered that the moisture content adsorbed by the adsorption layer is low, and the adsorption capacity of the adsorption layer is not close to saturation. At this time, the heating sheet does not need to work, and the small amount of sweat can be adsorbed by the adsorption layer. It should be noted here that the second threshold can be set by those skilled in the art, and the embodiments of the present disclosure do not limit this.

[0113] In specific implementation, during the use of the head-mounted display device, when a large amount of sweat is discharged from the skin surface of the wearer, it will be absorbed by the adsorption layer on the bottom shell through capillary action. As the sweat stains increase, the sweat will flow towards the dry part of the adsorption layer. At the same time, the humidity sensor can collect the humidity value of the closed space between the wearer and the bottom shell in real time, and send the collected humidity value to the control chip. When the control chip detects that the humidity value is greater than or equal to the second threshold, that is, when the moisture content of the adsorption layer reaches a certain level and the adsorption capacity of the adsorption layer is close to saturation, the control chip controls the heating sheet to heat the adsorption layer near the exhaust hole, so that the moisture in the adsorption layer at that place is heated and accelerated to vaporize, and is discharged through the exhaust hole, so that the moisture content of the adsorption layer near the exhaust hole is reduced, and the moisture content of the adsorption layer near the exhaust hole is always lower than other parts of the adsorption layer, further making the moisture in the adsorption layer always flow towards the exhaust hole, that is, the water in the adsorption layer flows towards the exhaust holes on both sides and is discharged. When the control chip detects that the humidity value of the wearer's skin is less than the second threshold, it controls the heating sheet to stop heating.

[0114] In this embodiment, the humidity sensor is used to monitor the humidity value of the closed space between the wearer and the bottom shell in real time, and when the humidity value is greater than or equal to the second threshold, the heating sheet is controlled to heat. In this way, the detection accuracy can be improved, so that the moisture in the adsorption layer can be discharged in time, and the discomfort caused by a large amount of sweat generated by the wearer can be avoided.

[0115] According to an embodiment of the present disclosure, during the use of the head-mounted display device, a first detection value collected by a sensor is obtained, and based on the first detection value, the heating sheet of the head-mounted display device is controlled to work. In this way, when the wearer generates a large amount of sweat, the adsorption layer can adsorb the sweat generated by the wearer, and the heating sheet can heat the adsorption layer near the exhaust hole. The moisture in the adsorption layer at that place is heated and accelerated to vaporize and discharged, so that the moisture content of the adsorption layer near the exhaust hole is always lower than other parts of the adsorption layer, further making the moisture in the adsorption layer always flow towards the exhaust hole and be discharged, so that the sweat generated by the wearer can be discharged in time, and the generation of water vapor in the closed space between the wearer and the head-mounted display device can be avoided. In addition, the adsorption layer can be kept dry, and the discomfort caused by a large amount of sweat generated by the wearer can be avoided, so as to improve the user experience.
