Referring to fig. 1 to 5, a head-mounted display apparatus 1000 according to an embodiment of the present invention includes: a housing 100, a display screen 200, an optical system 300, a circuit element 400, and a heat conductive member 500. The housing 100 includes a first side 120 proximate to a user and a second side 140 opposite the first side 120. The display screen 200, the optical system 300, the circuit element 400, and the heat conductive member 500 are disposed within the case 100. The first end 520 of the heat conductive member 500 is connected to at least one of the display screen 200, the optical system 300, and the circuit element 400. The second end 540 of the thermally conductive member 500 is disposed at the first side 120. The second end 540 of the heat conductive member 500 corresponds to the eyes of the user when the user uses the head-mounted display device 1000.
The head-mounted display apparatus 1000 according to the embodiment of the invention conducts or radiates heat of at least one of the display screen 200, the optical system 300, and the circuit element 400 to the eyes of the user using the heat conduction member 500, so that the eye fatigue of the user can be alleviated and the heat accumulation of the head-mounted display apparatus 1000 can be reduced.
Referring to fig. 6, in some embodiments, the case 100 may include a visor 160, and the visor 160 completely seals the display screen 200, the optical system 300, and the circuit element 400 when the user uses the head-mounted display device 1000, so that immersion may be increased, and heat accumulation of the display screen 200, the optical system 300, and the circuit element 400 may be facilitated, thereby enabling the heat conduction member 500 to conduct or radiate sufficient heat to the eyes of the user.
In some embodiments, the display 200 may be a liquid crystal display or an Organic Light-Emitting Diode (OLED) display. The optical system 300 may include one or more lens groups, and the optical system 300 is used for transmitting the picture displayed by the display screen 200, and the display screen 200 is generally disposed between the second side of the housing 100 and the optical system 300. The circuit element 400 may include a circuit board and electronics (e.g., capacitors, resistors, processors, etc.) disposed on the circuit board.
In some embodiments, the first end 520 of the heat conducting member 500 is connected to at least one of the display screen 200, the optical system 300 and the circuit element 400, and it is understood that the first end 520 is connected to the display screen 200, or the first end 520 is connected to the optical system 300, or the first end 520 is connected to the circuit element, or the first end 520 is connected to the display screen 200 and the optical system 300, or the first end 520 is connected to the display screen 200 and the circuit element 400, or the first end 520 is connected to the optical system 300 and the circuit element 400, or the first end 520 is connected to the display screen 200, the optical system 300 and the circuit element 400.
In some embodiments, when the user uses the head-mounted display device 1000, the second end 540 of the heat conducting member 500 corresponds to the eyes of the user, and it can be understood that the second end 540 of the heat conducting member 500 is disposed close to the eyes of the user, and particularly, the second end 540 may be disposed around the eyes of the user, so as to avoid the danger that the second end 540 may contact with the eyes of the user, and may not obstruct the user from viewing the picture displayed by the display screen 200. In addition, the second end 540 may be disposed close to acupuncture points around the user's eyes, so that the heat guided by the heat conduction member 500 can massage the relevant acupuncture points around the user's eyes, thereby improving a massage effect and relieving eye fatigue of the user to a greater extent.
In some embodiments, the second end 540 of the heat conductive member 500 may be dotted or have a sheet shape. When the second end 540 of the heat conductive member 500 is dotted, heat can be accurately and concentratedly transferred to acupuncture points around the eyes of the user. When the second end 540 of the heat conductive member 500 is shaped like a sheet, the head-mounted display device 1000 may be more suitable for different users.
In some embodiments, in order to reduce or avoid the heat conducting member 500 from affecting the user's view of the display screen 200, the heat conducting member 500 may be disposed to avoid the user's view, for example, the heat conducting member 500 is designed to be arc-shaped, the heat conducting member 500 is not disposed in the display area of the display screen 200, and the like. In addition, the influence of the heat conduction member 500 on the user's view can also be reduced by reducing the number of the heat conduction members 500.
Referring to fig. 1, in some embodiments, the second end 540 of the thermally conductive member 500 extends from the first side 120 and is spaced apart from the user's eyes.
As such, the second end 540 of the heat conductive member 500 may be disposed in the air and transfer heat to the eyes of the user using heat radiation.
In some embodiments, the first side 120 of the housing 100 may be located far from the eyes of the user, and in order to enable the second end 540 of the heat-conducting member 500 to be disposed close to the eyes of the user, the second end 540 of the heat-conducting member 500 may protrude from the first side 120 of the housing 100, thereby shortening the distance between the second end 540 of the heat-conducting member 500 and the eyes of the user and facilitating the heat transfer from the second end 540 of the heat-conducting member 500 to the eyes of the user. To reduce the risk of the second end 540 of the thermally conductive member 500 coming into contact with the user's eyeball, the second end 540 extending from the first side 120 may be spaced from the user's eyes. When the second end 540 of the heat conductive member 500 is spaced apart from the user's eyes, the second end 540 of the heat conductive member 500 transfers heat to the user's eyes mainly by means of heat radiation.
Referring to fig. 2, in some embodiments, the second end 540 of the thermal conduction member 500 is completely received in the housing 100 and spaced apart from the eyes of the user.
As such, the second end 540 of the heat conductive member 500 may be received within the case 100 and transfer heat to the eyes of the user using heat radiation.
In some embodiments, the first side 120 of the housing 100 may be sufficiently close to the eyes of the user, and thus the second end 540 of the heat-conducting member 500 may be completely received in the housing 100, thereby avoiding an increase in manufacturing cost caused by unnecessarily lengthening the heat-conducting member 500 without affecting the heat transfer from the second end 540 of the heat-conducting member 500 to the eyes of the user. In order to reduce the risk of the second end 540 of the heat conductive member 500 coming into contact with the eyeball of the user, the second end 540 completely received in the housing 100 may be spaced apart from the eyes of the user. When the second end 540 of the heat conductive member 500 is spaced apart from the user's eyes, the second end 540 of the heat conductive member 500 transfers heat to the user's eyes mainly by means of heat radiation.
Referring to fig. 3, in some embodiments, the second end 540 of the thermal conduction member 500 extends from the first side 120 and fits the eyes of the user.
In this way, the second end 540 of the heat conducting member 500 can be suspended and can transfer heat to the eyes of the user by using heat conduction.
In some embodiments, the first side 120 of the housing 100 may be located far from the eyes of the user, and in order to enable the second end 540 of the heat-conducting member 500 to be disposed close to the eyes of the user, the second end 540 of the heat-conducting member 500 may protrude from the first side 120 of the housing 100, thereby shortening the distance between the second end 540 of the heat-conducting member 500 and the eyes of the user and facilitating the heat transfer from the second end 540 of the heat-conducting member 500 to the eyes of the user. To improve the efficiency of the second end 540 of the heat conductive member 500 in transferring heat to the user's eyes, the second end 540 protruding from the first side 120 may be fitted to the user's eyes. When the second end 540 of the heat conduction member 500 is engaged with the eyes of the user, the second end 540 of the heat conduction member 500 mainly transfers heat to the eyes of the user by means of heat conduction.
Referring to fig. 4, in some embodiments, the second end 540 of the thermal conduction member 500 is completely received in the casing 100 and is attached to the eyes of the user.
As such, the second end 540 of the heat conductive member 500 may be received within the case 100 and transfer heat to the eyes of the user by means of heat conduction.
In some embodiments, the first side 120 of the housing 100 may be sufficiently close to the eyes of the user, and thus the second end 540 of the heat-conducting member 500 may be completely received in the housing 100, thereby avoiding an increase in manufacturing cost caused by unnecessarily lengthening the heat-conducting member 500 without affecting the heat transfer from the second end 540 of the heat-conducting member 500 to the eyes of the user. In order to improve the efficiency of the second end 540 of the heat conductive member 500 in transferring heat to the eyes of the user, the second end 540 completely received in the casing 100 may be attached to the eyes of the user. When the second end 540 of the heat conduction member 500 is engaged with the eyes of the user, the second end 540 of the heat conduction member 500 mainly transfers heat to the eyes of the user by means of heat conduction.
In some embodiments, the thermally conductive member 500 is spaced from the housing 100.
In this way, the heat transfer of the heat conductive member 500 to the case 100 can be reduced, thereby reducing the loss of heat.
Specifically, the first end 520 of the heat conductive member 500 is connected to at least one of the display screen 200, the optical system 300, and the circuit element 400, and the other portions of the heat conductive member 500 are suspended, so that the heat conductive member 500 is spaced apart from the housing 100.
Of course, in some embodiments, the heat conduction member 500 may also be in contact with the housing 100, for example, the heat conduction member 500 is fixed by the first side 120 of the housing 100, so that the heat conduction member 500 is not easily shaken. Specifically, a through hole may be formed at the first side 120 of the case 100, and the second end 540 of the heat conductive member 500 is fixed in or protruded from the through hole. In one embodiment, the heat conductive member 500 has a cylindrical shape, the heat conductive member 500 has a circular cross-section, a circular through hole is formed at the first side 120 of the case 100, and the second end 540 of the heat conductive member 500 is fixed in or protruded from the through hole. The heat conduction member 500 is in contact with the casing 100, and the heat of the heat conduction member 500 can be transferred to other positions of the head of the user through the casing, so that the massage effect on other positions of the head of the user is realized.
Referring to fig. 1-5, in some embodiments, the second end 540 of the heat conduction member 500 is formed with a fitting portion 542, and the material of the fitting portion 542 includes a thin cotton material.
In this way, the injury of the heat conduction member 500 to the user may be reduced, and the fitting portion 542 is brought into elastic contact with the user's eyes when the heat conduction member 500 fits the user's eyes.
In some embodiments, the fitting portion 542 can wrap the second end 540 of the heat conducting member 500, so as to reduce the possibility that the second end 540 of the heat conducting member 500 may cause damage to the eyes of the user, which makes the eyes of the user feel better when contacting the heat conducting member 500. The thin cotton material includes pure cotton material, silk floss material, sponge material and the like, the thin cotton material is soft and elastic, and the comfort level of a user can be improved by utilizing the attaching part 542 formed by the thin cotton material to attach to the user. In addition, the heat transfer efficiency of the attaching portion 542 can be improved by using a heat-dissipating thin cotton material having a good heat conduction effect.
Of course, the material of the fitting portion 542 may be other soft or elastic materials, such as rubber materials, and is not limited in particular.
In some embodiments, the material of the heat conductive member 500 includes graphene, carbon nanotubes, and thermally conductive silicone grease.
In this way, the heat conduction member 500 can be formed by using a material having a high heat transfer capability.
Referring to FIG. 5, in some embodiments, the display panel 200 includes a display panel high heat region 220, and the first end 520 of the heat conductive member 500 is connected to the display panel high heat region 220; and/or the optical system 300 includes an optical system high heat region 320, the first end 520 of the heat conductive member 500 is connected to the optical system high heat region 320; and/or the circuit element 400 includes a circuit element high heat region 420, the first end 520 of the thermally conductive member 500 being connected to the circuit element high heat region 420.
In the head-mounted display apparatus 1000 according to the embodiment, the first end 520 of the heat conduction member 500 is directly connected to the high heat region (the high heat region 220 of the display screen, the high heat region 320 of the optical system, and/or the high heat region 420 of the circuit element), and compared with the case that the first end 520 is directly connected to the low heat region except the high heat region, the heat in the high heat region is prevented from being transferred to the low heat region and then to the heat conduction member 500, so that the heat accumulation of the heat conduction member 500 is accelerated, and the heat transfer efficiency of the heat conduction member 500 is improved.
Specifically, before the head-mounted display device 1000 is used, the heat generation of the display screen 200, the optical system 300 and the circuit element 400 during the operation of the head-mounted display device 1000 can be measured through experiments, for example, after a predetermined period of time for starting the head-mounted display apparatus 1000, the area of the display screen 200 with a higher temperature (e.g., a temperature greater than a first preset temperature) is divided into the display screen high heat area 220, the area of the optical system 300 with a higher temperature (e.g., a temperature greater than a second preset temperature) is divided into the optical system high heat area 320, the area of the circuit element 400 with a higher temperature (e.g., a temperature greater than a third preset temperature) is divided into the circuit element high heat area 420, wherein the preset time can be taken as different values according to the requirements, the first preset temperature, the second preset temperature and the third preset temperature can also be taken as different values according to the requirements, and the first preset temperature, the second preset temperature and the third preset temperature may be the same or different. In one embodiment, the predetermined time period is 20 minutes, and the first preset temperature, the second preset temperature and the third preset temperature are all 40 degrees celsius.
In some embodiments, the first end 520 of the heat conducting member 500 is connected to the display screen high heat area 220, or the first end 520 of the heat conducting member 500 is connected to the optical system high heat area 320, or the first end 520 of the heat conducting member 500 is connected to the circuit component high heat area 420, or the first end 520 of the heat conducting member 500 is connected to the display screen high heat area 220 and the optical system high heat area 320, or the first end 520 of the heat conducting member 500 is connected to the display screen high heat area 220 and the circuit component high heat area 420, or the first end 520 of the heat conducting member 500 is connected to the optical system high heat area 320 and the circuit component high heat area 420, or the first end 520 of the heat conducting member 500 is connected to the display screen high heat area 220, the optical system high heat area 320 and the circuit.
In some embodiments, the heat conducting member 500 includes a plurality of heat conducting members 500, and the plurality of heat conducting members 500 are connected to at least one of the display panel 200, the optical system 300, and the circuit element 400.
As such, heat transfer may be performed using a plurality of heat transfer members 500 to improve heat transfer efficiency.
Specifically, the first end 520 of one heat conductive member 500 may be connected to only one connection region of the display panel 200, the optical system 300, or the circuit element 400 (e.g., the display panel high heat region 220, the optical system high heat region 320, or the circuit element high heat region 420), so that the structure of the heat conductive member 500 may be prevented from being complicated, and heat transfer from among the connection regions may be prevented. When a plurality of connection regions exist in the display panel 200, the optical system 300, or the circuit element 400, the plurality of connection regions may be connected by the plurality of heat conductive members 500, respectively.
Referring to fig. 1 to 5, in some embodiments, the head-mounted display device 1000 includes a temperature detection unit 600, and the temperature detection unit 600 may be used to detect the temperature of the second end 540 of the heat conduction member 500.
In this manner, the temperature of the second end 540 of the heat conductive member 500 can be detected.
It is understood that when the temperature of the second end 540 of the heat conductive member 500 is too high, a burn or user discomfort may occur, and thus the temperature of the second end 540 of the heat conductive member 500 may be detected using the temperature detecting unit 600.
In some aspects, the temperature detection unit 600 may be a non-contact temperature detection unit (e.g., an infrared temperature measurement sensor), so that the temperature of the second end 540 of the heat conductive member 500 may be detected and obtained without the temperature detection unit 600 contacting the second end 540 of the heat conductive member 500, and the heat loss of the second end 540 of the heat conductive member 500 may be reduced.
Of course, in some embodiments, the temperature detection unit 600 may also be a contact temperature detection unit (e.g., a temperature measurement sensor including a thermistor), and is not limited in particular.
In some embodiments, the display screen 200 displays a warning screen when the temperature is higher than a preset temperature.
As such, the user may be prompted through the display screen 200 when the temperature is greater than the preset temperature.
Specifically, the preset temperature may be stored in the head-mounted display device 1000 in advance or set by the user, for example, 42 degrees celsius. When the temperature is higher than the preset temperature, user discomfort or user scalding risks may occur.
In some embodiments, the display 200 displays a warning screen, which may be a mode of displaying an over-temperature, displaying a current temperature, or flashing a display screen, and is not limited herein.
In some embodiments, the head mounted display device 1000 includes an electro-acoustic element (e.g., an earphone or a speaker, etc.) through which a user may be prompted to sound when the temperature is greater than a preset temperature.
In some embodiments, the head mounted display device 1000 is turned off when the temperature is greater than a preset temperature.
As such, the head-mounted display apparatus 1000 may be turned off when the temperature is greater than the preset temperature.
Specifically, the preset temperature may be stored in the head-mounted display device 1000 in advance or set by the user, for example, 42 degrees celsius. When the temperature is higher than the preset temperature, user discomfort or user scalding risks may occur. Therefore, when the temperature is greater than the preset temperature, the head-mounted display device 1000 is turned off, so that the head-mounted display device 1000 does not generate heat continuously, thereby avoiding the occurrence of danger.
In the present invention, unless otherwise expressly stated or limited, "above" or "below" a first feature means that the first and second features are in direct contact, or that the first and second features are not in direct contact but are in contact with each other via another feature therebetween. Also, the first feature being "on," "above" and "over" the second feature includes the first feature being directly on and obliquely above the second feature, or merely indicating that the first feature is at a higher level than the second feature. A first feature being "under," "below," and "beneath" a second feature includes the first feature being directly under and obliquely below the second feature, or simply meaning that the first feature is at a lesser elevation than the second feature.
