Therefore, the features specified as "first" or "second" may explicitly or implicitly include at least one such feature. Furthermore, the technical solutions of the various embodiments may be combined with each other, but only on the basis that they can be implemented by a person of ordinary skill in the art. If the combination of technical solutions is mutually contradictory or cannot be implemented, it shall be deemed that such combination of technical solutions does not exist and is not within the scope of protection claimed by the present invention.

[0050] Reference Figure 1 , Figure 1 Schematic diagram of the structure of the first embodiment of the head-mounted display device of the present invention.

[0051] like Figure 1 As shown, in this embodiment, the device includes: an eye mask 100 , a detachable display module 200 and a main body 300 .

[0052] The eye mask 100 is adsorbed on the display module 200 via an eye mask adsorption magnet.

[0053] When the display module 200 is separated from the main body 300 , the display module 200 transmits audio and video data with the main body 300 via a connecting line communication or wireless communication.

[0054] It should be noted that the display module 200 may be the part of the head mounted display device that displays virtual content.

[0055] It is understood that the main body 300 is the portion of the head-mounted display device that runs complex graphics rendering and real-time tracking algorithms to generate virtual content. The main body 300 can be used to implement the various functions of the head-mounted display device and includes a battery for powering each functional module and a heat dissipation system for heat dissipation.

[0056] In a specific implementation, the display module 200 and the main body 300 of the head mounted display device can be separated and the eye mask 100 is fixed on the display module 200 by an adsorption magnet. Figure 1 As shown, when the user needs to watch audio and video content, the eye mask 100 contacts the human eye, and the user can watch the virtual content provided by the head-mounted display device through the eye mask 100.

[0057] Accordingly, when the user needs to use the device for an extended period, the display module 200 can be separated from the main body 300. After separation, the display module 200 can be connected to the main body 300 via a cable for audio and video transmission. The display module 200 can also establish a wireless connection with the main body 300, such as a Wi-Fi connection or a Bluetooth connection, for audio and video data transmission via wireless communication.

[0058] It should be understood that since the main body 300 includes a large number of functional modules to provide virtual content to the user, these modules are relatively heavy. Accordingly, the batteries and cooling systems that power these modules also have a certain weight, limiting the space available for reducing the overall weight of the head-mounted display device. This embodiment allows the heavier main body 300 to be separated from the display module 200, so that the head-mounted display device worn by the user consists of the eye mask 100 and the display module 200. This significantly reduces the wearing weight and improves user comfort. Furthermore, the head-mounted display device can still be used normally after separation, effectively improving the user experience.

[0059] The head-mounted display device of this embodiment includes: an eye mask, a detachable display module, and a main body; the eye mask is attached to the display module via an eye mask attachment magnet; when the display module is separated from the main body, the display module transmits audio and video data with the main body via a connecting line or wireless communication. Compared to the existing head-mounted display devices that require the configuration of related auxiliary modules with certain weights for different functional modules, resulting in a larger head-mounted display device, the head-mounted display device of this embodiment can separate the display module from the main body, while still being able to transmit audio and video data after separation. Moreover, since most of the functional modules are arranged in the main body, separating the display module from the main body during use can reduce the overall weight of the device, effectively improving the user's wearing comfort and thereby enhancing the user experience.

[0060] refer to Figure 2 , Figure 2 Schematic diagram of the structure of the second embodiment of the head-mounted display device of the present invention.

[0061] Based on the above first embodiment, in this embodiment, the display module 200 is provided with a first USB interface 201 ; the main body 30 is provided with a second USB interface 301 .

[0062] The first USB interface 201 is connected to the second USB interface via a USB cable; the main body 300 supplies power to the display module 200 via the USB cable.

[0063] It should be noted that the first USB interface 201 may be a serial bus interface provided in the display module 200 for mutual communication between the display module 200 and the main body 300 , such as a Type cDP to MIPI interface.

[0064] It is understandable that the second USB interface 301 may be provided in the main body 300 and is used for a serial bus interface for mutual communication between the main body 300 and the display module 200 , such as a Type c MIPI to DP interface.

[0065] It should be noted that Figure 2 The detachable display module is the display module 200 mentioned above, and the VR / MR main body is the main body 300 mentioned above. When the display module 200 and the main body 300 are not separated, they can be fixedly connected by structural parts.

[0066] In a specific implementation, one end of the USB cable is connected to the first USB port 201, and the other end is connected to the second USB port 301. The main body 300 can transmit power to the display module 200 through the USB cable to power the display module 200 and ensure normal operation of the display module 200.

[0067] Furthermore, in this embodiment, the main body 300 is further provided with an external power supply interface 302 .

[0068] When the main body 300 supplies power to the display module 200 via the USB connection cable, the main body 300 receives power from an external power source via the external power supply interface 302 .

[0069] In the specific implementation, for ease of understanding, Figure 2 In the figure, external power supply refers to the external power supply interface 302 in the main body 300. The external power supply interface 302 can be connected to a power line to receive power from an external power source to ensure that the main body 300 can operate normally.

[0070] In addition, if Figure 2 As shown, the main body 300 is also equipped with a battery and charging and discharging module, a camera / sensor, and other peripheral modules. The battery and charging and discharging module is used to process the power provided by the external power source to power the various modules in the main body 300. At the same time, the battery and charging and discharging module can also store the power provided by the external power source to power the display module 200.

[0071] Furthermore, in this embodiment, the display module 200 is further provided with a first wireless module 202 , and the main body is further provided with a second wireless module 303 ;

[0072] When the display module 200 is separated from the main body 300 , if the first wireless module 202 and the second wireless module 303 successfully establish a wireless communication connection, the display module 200 transmits audio and video data with the main body 300 through the wireless communication connection after being powered on.

[0073] It should be noted that both the first wireless module 202 and the second wireless module 303 may be modules with wireless communication functions, such as a Wi-Fi module or a Bluetooth module.

[0074] In a specific implementation, the first wireless module 202 of the above-mentioned display module 200 can establish a wireless communication connection with the second wireless module 303 of the main body 300. When the display module 200 is separated from the main body 300, the main body 300 can wirelessly transmit audio and video data to the display module 200 through the wireless communication connection.

[0075] Furthermore, in this embodiment, when the display module 200 is separated from the main body 300, if the first wireless module 202 and the second wireless module 303 fail to successfully establish a wireless communication connection, the display module 200 transmits audio and video data with the main body 300 through the USB cable after powering on.

[0076] In a specific implementation, when the first wireless module 202 and the second wireless module 303 have not established a wireless communication connection, since the main body 300 is connected to the display module 200 via a USB cable and the display module 200 is powered by the USB cable, at this time, if the display module 200 is separated from the main body 300, the main body 300 can transmit audio and video data to the display module 200 via the USB cable.

[0077] In this embodiment, when the display module 200 is separated from the main body 300, if the first wireless module 202 and the second wireless module 303 successfully establish a wireless communication connection, the main body 300 transmits audio and video data to the display module 200 through the wireless communication connection; if the first wireless module 202 and the second wireless module 303 fail to successfully establish a wireless communication connection, the main body 300 transmits audio and video data to the display module 200 through a USB connection cable, thereby achieving the goal of still being able to accurately display virtual content after the display module 200 is separated from the main body 300, thereby effectively improving the display accuracy.

[0078] Further, refer to Figure 3 , Figure 3 Schematic diagram of the first surface structure of the display module in the second embodiment of the head-mounted display device of the present invention. Figure 3 It can be a rear view of the display module 200, i.e. Figure 1 In the direction from the main body 300 to the human eye, the Figure 3 The structure involved in the portion between the display module 200 and the main body 300 can be characterized.

[0079] like Figure 3 As shown, in this embodiment, the first surface of the display module is provided with a Pogopin contact array and an HMD magnetic attraction position.

[0080] The Pogopin contact array 203 is located in the central area of ​​the first surface; the HMD magnetic attraction position 204 is located in the edge area of ​​the first surface; and an HMD adsorption magnet is located in the HMD magnetic attraction position 204 .

[0081] When the display module 200 is not separated from the main body 300 , the display module 200 is connected to the main body 300 via the HMD adsorption magnet, and the display module 200 transmits audio and video data with the main body 300 via the Pogopin contact array 203 .

[0082] It should be noted that the first surface of the display module 200 may be the surface where the display module 200 contacts the main body 300 .

[0083] In a specific implementation, HMD magnetic positions 204 can be set at the junction of two adjacent edges of the first surface, for a total of four HMD magnetic positions 204, each of which can be equipped with an HMD magnet. The display module 200 is attached to the main body 300 via the HMD magnet, connecting to the main body 300. When the display module 200 and the main body 300 do not need to be separated, the main body 300 can transmit audio and video data to the display module 200 via the pogopin contact array 203.

[0084] Accordingly, when the display module 200 and the main body 300 need to be separated, the HMD adsorption magnet and the Pogopin contact array 203 can be removed to separate the display module 200 from the main body 300 .

[0085] In addition, if Figure 3 As shown, a plurality of positioning holes 205 are further provided on the first surface of the display module 200 for positioning the relative positions of the display module 200 and the main body 300, so that when the display module 200 and the main body 300 do not need to be separated, the display module 200 can be aligned with the above-mentioned main body 300, thereby allowing the display module 200 to be adsorbed in the correct position of the main body 300 through the above-mentioned HMD adsorption magnet without deviation.

[0086] Further, refer to Figure 2 In this embodiment, the display module 200 is further provided with a first Pogopin interface 206 , and the main body is further provided with a second Pogopin interface 304 .

[0087] One end of the Pogopin contact array 203 is disposed in the first Pogopin interface 206 .

[0088] When the display module 200 is not separated from the main body 300 , the other end of the Pogopin contact array 203 is connected to the second Pogopin interface 304 .

[0089] In a specific implementation, when the display module 200 is not separated from the above-mentioned main body 300, one end of the above-mentioned Pogopin contact array 203 can be connected to the above-mentioned first Pogopin interface 206, and the other end can be connected to the above-mentioned Pogopin interface 304, so that the Pogopin contact array 203 can accurately transmit the audio and video data generated by the main body 300 to the display module 200.

[0090] Further, refer to Figure 2 In this embodiment, the display module 200 includes a first processor 207 and the display module 208 , and the main body 300 includes a second processor 305 .

[0091] The first processor 207 is connected to the first wireless module 202 and the display module 208 respectively; the display module 208 is connected to the first USB interface 201 and the first Pogopin interface 206 respectively.

[0092] The second processor 305 is connected to the second wireless module 303 , the second Pogopin interface 304 , and the second USB interface 301 respectively.

[0093] It should be noted that since the main body 300 needs to run complex graphics rendering and real-time tracking algorithms to generate virtual content, the main body 305 has high performance requirements for the second processor 305. Figure 2 The second processor 305 is represented by a high-performance processor. The display module 200 is used to display the performance content generated by the main body 300 and does not participate in the calculation. Therefore, the display module 200 does not have high performance requirements for the first processor 207, so the first processor 207 is directly represented by a processor.

[0094] It is understandable that the above-mentioned first processor 207 can be connected to the above-mentioned first wireless module 202 through a PCIE communication bus, the above-mentioned first processor 207 can be connected to the above-mentioned display module 208 through a MIPI communication bus, and the above-mentioned second processor 207 can be connected to the above-mentioned second wireless module 303 through a PCIE communication bus.

[0095] In a specific implementation, the above-mentioned second processor 305 can generate virtual content (i.e., audio and video data) through graphics rendering and real-time tracking algorithms. When the display module 200 is not separated from the above-mentioned main body 300, the second processor 305 can transmit audio and video data to the first Pogopin interface 206 in the display module 200 through the Pogopin contact array 203 connected to the second Pogopin interface 304, and then the first processor 207 can obtain the audio and video data, and display the audio and video data on the display module 208 after corresponding processing.

[0096] It should be understood that when the display module 200 is not separated from the above-mentioned main body 300, if the second wireless module 303 has established a wireless connection with the first wireless module 202, the second processor 305 can wirelessly transmit audio and video data to the first wireless module 202 of the display module 200 through the second wireless module 303, and the first processor 207 can obtain the audio and video data, and display the audio and video data on the display module 208 after corresponding processing.

[0097] Accordingly, when the display module 200 is not separated from the above-mentioned main body 300, if the second wireless module 303 has not established a wireless connection with the first wireless module 202, the second processor 305 can transmit audio and video data to the first USB interface 201 of the display module 200 through the USB connection cable connected to the second USB interface 301, and the first processor 207 can obtain the audio and video data, and display the audio and video data on the display module 208 after corresponding processing.

[0098] refer to Figure 4 , Figure 4 2 is a schematic structural diagram of a third embodiment of a head-mounted display device according to the present invention.

[0099] Based on the above embodiments, in this embodiment, the second surface of the display module 200 is provided with a left-eye lens module 209 , an IPD adjustment module 210 , a right-eye lens module 211 and an eye mask magnetic position 212 .

[0100] The IPD adjustment module 210 is arranged between the left-eye lens module 209 and the right-eye lens module 211; the eye mask magnetic position 212 is arranged in the edge area of ​​the second surface; the eye mask adsorption magnet is provided in the eye mask magnetic position 212; the eye mask 100 is connected to the display module 200 via the eye mask adsorption magnet.

[0101] It should be noted that Figure 4 It can be a front view of the display module 200, i.e. Figure 1 In the direction from the human eye to the display module 200, the Figure 4 The structure between the eye mask 100 and the display module 200 can be characterized.

[0102] It is understandable that the left-eye lens module 209 corresponds to the left eye of the user, and the right-eye lens module 211 corresponds to the right eye of the user.

[0103] It should be noted that the above-mentioned IPD adjustment module 210 can be used to adjust the interocular distance to improve the clarity, realism and comfort of virtual content, thereby enhancing the user's immersion in the virtual reality environment.

[0104] In a specific implementation, eye mask magnetic locations 212 are provided at the junction of two adjacent curves on the second surface, for a total of four eye mask magnetic locations 212. Each eye mask magnetic location 212 is equipped with an eye mask magnet. The eye mask 100 is attached to the display module 200 via the magnets, connecting the display module 200. After the user wears the head-mounted display device, they can view virtual content displayed on the display module 208 through the left-eye lens module 209 and can adjust the left-eye lens module 209 for optimal viewing.

[0105] In addition, since the eye mask 100 is adsorbed on the display module 200 by the eye mask adsorption magnet, when the user needs to remove the eye mask 100, the eye mask adsorption magnet can be removed without any additional complicated operations.

[0106] Further, refer to Figure 5 , Figure 5 Schematic diagram of the side surface structure of the display module in the third embodiment of the head-mounted display device of the present invention. Figure 5 It can be a side view of the display module 200, that is, a side view connecting the first surface and the second surface of the display module 200. Figure 3 The structure involved in the side portion of the display module 200 can be characterized.

[0107] like Figure 5 As shown, in this embodiment, a strap connection position 213 is provided on the side surface of the display module 200 .

[0108] When the display module 200 is separated from the main body 300 , the strap connection position 213 is connected to the head strap.

[0109] In a specific implementation, the above-mentioned strap connection position 213 can be connected to a head strap. When the display module 200 is separated from the main body 300, the head strap allows the user to more conveniently wear the head-mounted display device or the eye mask 100 and the display module 200 as a whole on the head for use.

[0110] It should be understood that the first USB port 201 may also be disposed on the side surface of the display module 200 and below the strap connection position 213 .

[0111] In this embodiment, the eye mask magnetic attraction position is set at the edge area of ​​the second surface, and the eye mask adsorption magnet is provided in the eye mask magnetic attraction position 212. The eye mask 100 is connected to the display module 200 via the eye mask adsorption magnet, thereby achieving a stable connection between the eye mask 100 and the display module 200. The user can also separate the eye mask 100 from the display module 200 by removing the eye mask adsorption magnet, thereby effectively improving the user experience.
