[0038] It should be noted that the modifications of "one" and "plurality" mentioned in the present application are illustrative rather than restrictive, and those skilled in the art should understand that unless otherwise clearly indicated in the context, it should be understood as "one or more".

[0039] The names of the messages or information exchanged between multiple devices in the embodiments of the present disclosure are only used for illustrative purposes and are not used to limit the scope of these messages or information.

[0040] The embodiments of the present application can be applied to various application scenarios such as extended reality, virtual reality, augmented reality, and mixed reality.

[0041] First, some nouns or terms that appear in the description of the embodiments of the present application are explained as follows:

[0042] Extended Reality (XR) is a concept that includes Virtual Reality (VR), Augmented Reality (AR) and Mixed Reality (MR). It refers to the technology that creates an environment in which the virtual world is connected to the real world, and users can interact with the environment in real time.

[0043] Virtual Reality (VR) is a technology for creating and experiencing a virtual world. It generates a virtual environment by computation. It is a multi-source information (the virtual reality mentioned in this article includes at least visual perception, and can also include auditory perception, tactile perception, motion perception, and even taste perception, olfactory perception, etc.). It realizes the simulation of the fusion and interactive three-dimensional dynamic vision and entity behavior of the virtual environment, immersing users in a simulated virtual reality environment, and realizing its application in various virtual environments such as maps, games, videos, education, medical treatment, simulation, collaborative training, sales, assisted manufacturing, maintenance and repair.

[0044] Augmented Reality (AR) is a technology that calculates the camera's posture parameters in the real world (or three-dimensional world, real world) in real time during the process of the camera capturing images, and adds virtual elements to the images captured by the camera based on the camera posture parameters. Virtual elements include but are not limited to: images, videos and three-dimensional models. The goal of AR technology is to integrate the virtual world with the real world on the screen for interaction.

[0045] Mixed Reality (MR) is a simulated setting that integrates computer-created sensory input (e.g., virtual objects) with sensory input from a physical setting or its representation. In some MR settings, the computer-created sensory input can adapt to changes in sensory input from the physical setting. In addition, some electronic systems used to present MR settings can monitor the orientation and / or position relative to the physical setting so that virtual objects can interact with real objects (i.e., physical elements from the physical setting or their representations). For example, the system can monitor movement so that virtual plants appear stationary relative to physical buildings.

[0046] Augmented Virtuality (AV), AV scenery refers to a simulated scenery in which a computer-created scenery or a virtual scenery incorporates at least one sensory input from a physical scenery. One or more sensory inputs from a physical scenery may be a representation of at least one feature of the physical scenery. For example, a virtual object may present the color of a physical element captured by one or more imaging sensors. For another example, a virtual object may present features consistent with actual weather conditions in a physical scenery, as identified via weather-related imaging sensors and / or online weather data. In another example, an augmented reality forest may have virtual trees and structures, but animals may have features accurately reproduced from images taken of physical animals.

[0047] The head-mounted display device needs to be worn on the user's head. Since the head circumference of different people is different, there will be differences between men and women, the young and the old, and different races. In order to better improve the user experience, you can choose whether to use the top strap of the head-mounted device according to personal usage. This requires the top strap to be able to be quickly disassembled and assembled according to actual conditions.

[0048] In the related art, a top strap is connected between the visual module part at the front and the battery compartment part at the rear of the head-mounted display device. In order to install the top strap, two fixing rings are provided on the top of the visual module and the battery compartment, and the two ends of the top strap can be installed and fixed by the two fixing rings respectively.

[0049] However, when installing the top strap, one end of the top strap needs to be passed through the two fixing rings at the same time, and then passed through between the two fixing rings. The installation and removal are relatively complicated. After the top strap is removed, the fixing ring will be left on the head-mounted display device. The fixing ring can shake on the head-mounted display device, thereby scratching other objects, and the aesthetics is poor.

[0050] In order to solve at least one of the above problems, the embodiment of the present application provides a connection device and a head-mounted display device, by setting a connection device between the device body and the strap of the head-mounted display device, the connection device includes a first component and a second component, the first component includes a connection member, the connection member includes a connection section and a protruding section connected in sequence along a first direction, and the protruding section protrudes from the peripheral side of the connection section; the second component includes a mounting member and a telescopic member, the mounting member is provided with a receiving groove for accommodating the first component, the inner side wall of the receiving groove is provided with a mounting groove, the telescopic member is telescopically arranged in the mounting groove, and the receiving groove includes a receiving section located between the telescopic member and the bottom wall of the receiving groove; if the connection member moves relative to the receiving groove along the first direction, the protruding section can push the telescopic member and move into the receiving section, and the telescopic member can protrude from the inner side wall to prevent the protruding section from detaching from the receiving section. When installing the strap, it is only necessary to align the connection member with the receiving groove, and then make the connection member move relative to the receiving groove along the first direction, so that the strap and the device body can be installed, and the operation is convenient and simple.

[0051] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0052] Figure 1 A schematic diagram of the structure of a head mounted display device provided in one embodiment of the present application; Figure 2 for Figure 1 Schematic diagram of the structure of the middle strap; Figure 3 for Figure 1The structural diagram of the main body of the device; Figure 4 for Figure 3 A schematic diagram of the structure of the first component; Figure 5 for Figure 1 A cross-sectional schematic diagram of the connecting device; Fig. 6A for Figure 1 A schematic diagram of the connecting device in the figure when the protruding section contacts the telescopic member during installation; Figure 6B for Figure 1 A schematic diagram of the protruding section of the connecting device pushing the telescopic member during installation; Figure 6C for Figure 1 Schematic diagram of the connection device at the end of installation. The first direction is Figure 5 In the bottom-up direction, FIG. 6A to FIG. 6C The arrow direction in the figure indicates the relative movement direction of the connector relative to the receiving groove. Figures 1 to 6C An embodiment of the present application provides a connecting device 10 that can be used in a head-mounted display device. The head-mounted display device may include a device body 20 and a strap 30. The connecting device 10 can be used to connect the strap 30 and the device body 20.

[0053] Figure 1 In the embodiment, the device body 20 may include a display module located at the front side and a battery compartment located at the rear side, and the two sides of the display module and the two sides of the battery compartment may be connected by a left strap and a right strap, and the top of the display module and the battery compartment may also be connected by a top strap. The strap 30 may be a top strap, or a left strap or a right strap.

[0054] In other embodiments, the device body may be an integrated structure including a display module and a battery compartment, the device body is located in front of the user's head, and its two ends may be connected by side straps so as to surround the user's head, and in addition, a top strap may be connected between the top of the device body and the middle of the side straps so that the top strap may cross the top of the user's head in the front-to-back direction. The straps in the embodiments of the present application may be top straps or side straps.

[0055] It can be understood that for a strap, one end of the strap 30 can be connected to the device body through a connecting device 10, and the other end can be connected through a non-detachable or fixed ring, or the two ends of the strap 30 can be connected to the device body 20 through a connecting device 10 respectively.

[0056] The connecting device 10 includes: a first component 100 and a second component 200, the first component 100 includes a connecting member 110, the connecting member 110 includes a connecting section 112 and a protruding section 111 sequentially connected along a first direction, the protruding section 111 protrudes from the peripheral side surface of the connecting section 112; the second component 200 includes a mounting member 210 and a telescopic member 220, the mounting member 210 is provided with a receiving groove 211 for accommodating the first component 100, the inner side wall of the receiving groove 211 is provided with a mounting groove 213, and the telescopic member 220 is telescopically arranged in the mounting groove 211. 13, and the accommodating groove 211 includes a accommodating section 212 located between the telescopic member 220 and the bottom wall of the accommodating groove 211; if the connecting member 110 moves relative to the accommodating groove 211 along the first direction, the protruding section 111 can push the telescopic member 220 and move into the accommodating section 212, and the telescopic member 220 can protrude from the inner side wall to prevent the protruding section 111 from detaching from the accommodating section 212; and one of the first component 100 and the second component 200 is used to connect the device body 20 of the head-mounted display device, and the other is used to connect the strap 30 of the head-mounted display device.

[0057] Among them, the first component 100 can be set on the shell of the device body 20, and the second component 200 can be set at one end of the strap 30, or the first component 100 can be set at one end of the strap 30, and the second component 200 can be set on the shell of the device body 20, thereby realizing the connection between the strap 30 and the device body 20.

[0058] For ease of explanation, the following description will be made by taking the strap 30 as the top strap, the first component 100 being disposed on the device body 20 , and the second component 200 being disposed on the front end of the top strap 30 as an example.

[0059] The first component 100 may include a connector 110 , which may be mounted on the device body 20 in a common manner, or a portion of the connector 110 may be integrally formed with the housing of the device body 20 through an integral molding process.

[0060] The connecting member 110 may include a cylindrical or prismatic connecting section 112, the connecting section 112 may extend along a first direction, and a protruding section 111 may be provided at the top of the connecting section 112 along the first direction, the protruding section 111 protruding from the surrounding side surfaces of the connecting section 112. One end of the connecting section 112 away from the protruding section 111 may be connected to the device body 20. The protruding section 111 may be integrally processed with the connecting section 112, or connected by common screw connection, welding, and the like.

[0061] The second component 200 may include a mounting member 210 and a telescopic member 220. The mounting member 210 may be a member made of plastic, metal or other materials. One end of the mounting member 210 may be connected to the strap 30 in a common manner. The other end of the mounting member 210 may be provided with a receiving groove 211. The receiving groove 211 may be a cylindrical structure. The receiving groove 211 has a bottom wall opposite to the opening and an inner side wall connected to the bottom wall. The inner side wall may be provided with a mounting groove 213. The mounting groove 213 may be provided at a position of the inner side wall close to the opening of the receiving groove 211.

[0062] A telescopic member 220 is provided in the mounting groove 213. It can be understood that the telescopic member 220 can be telescoped in the mounting groove 213 along a direction perpendicular to the first direction. The telescopic member 220 can be elastic, that is, it can be completely retracted into the mounting groove 213 under the action of an external force, and when the external force disappears, it can also extend out of the mounting groove 213, that is, protrude from the inner wall of the accommodating groove 211.

[0063] When installing the strap 30, the connecting member 110 can be aligned with the receiving groove 211, and then the strap 30 can be moved downward, that is, the connecting member 110 moves upward relative to the mounting member 210 in the first direction, and the top of the protruding section 111 can contact the telescopic member 220 (such as Fig. 6A ), continue to move the connecting member 110 upward, at this time, the connecting member 110 can push the telescopic member 220 to retract into the installation groove 213 (such as Figure 6B ), after the protruding section 111 enters the accommodating section 212, the telescopic member 220 can extend out of the mounting slot 213 again, approaching or even pressing against the connecting section 112, since there is no push from the protruding section 111, thereby preventing the protruding section 111 from escaping from the accommodating section 212 downward in a second direction opposite to the first direction, i.e., preventing the strap 30 from being separated from the device body 20 under tension.

[0064] The connection device provided in this embodiment only needs to insert the first component into the receiving groove 211 of the second component when installing the strap 30, so that the strap 30 and the device body can be automatically installed. It has a simple structure, fast and convenient installation, and high reliability.

[0065] It can be understood that in some embodiments, the telescopic member 220 can also be connected to a toggle member, and the telescopic member 220 can be retracted from the extended state into the mounting groove 213 by toggling the toggle member, so that when the strap is removed, the toggle member can be toggled to retract the telescopic member 220 into the mounting groove 213, and then the connecting member 110 can be pulled out from the accommodating groove 211 along the second direction, so that the strap 30 and the device body 20 can be separated.

[0066] In some embodiments, Figure 4The outer surface of the protruding section 111 facing away from the connecting section 112 constitutes a first surface 1112, and the area of ​​the region enclosed by the cross-sectional profile of the first surface 1112 gradually decreases along the first direction. During the installation process of the binding strap 30, the first surface 1112 can convert the force applied by the user to push the connecting member 110 along the first direction into a component force perpendicular to the first direction, and the component force can overcome the elastic force of the telescopic member 220, so that the protruding section 111 can push the telescopic member 220 to move in the direction of retracting into the installation groove 213.

[0067] In some embodiments, the first surface 1112 includes a hemispherical surface, which has a relatively smooth transition without sharp protrusions and turns, and is not easy to scratch or scrape surrounding objects and users.

[0068] Fig. 7A for Figure 1 A schematic diagram of the sliding member pushing the telescopic member when the connecting device is disassembled; Figure 7B for Figure 1 A schematic diagram of the connecting device in which the sliding member is located in the accommodating section when the connecting device is disassembled; Figure 7C for Figure 1 A schematic diagram of the sliding member and the protruding section cooperating with each other when the connecting device is disassembled; Fig.7D for Figure 1 A schematic diagram of the sliding member pushing the telescopic member when the connecting device is disassembled; Fig. 7E for Figure 1 Schematic diagram of the protruding section of the connecting device leaving the receiving section when disassembling.

[0069] Please refer to 7A to 7E In some embodiments, the first component 100 further includes: a sliding member 120, which is movably connected to the connecting section 112 so that the sliding member 120 can cooperate with or separate from the protruding section 111; when the protruding section 111 is located in the accommodating section 212, if the connecting member 110 is moved relative to the accommodating groove 211 in a first direction, the sliding member 120 can push the telescopic member 220 and move into the accommodating section 212, and if the connecting member 110 continues to move in a second direction opposite to the first direction, the sliding member 120 first moves relative to the connecting section 110 so that the protruding section 111 cooperates with the sliding member 120, and then the sliding member 120 can push the telescopic member 220 so that the sliding member 120 and the protruding section 111 are separated from the accommodating section 212.

[0070] The sliding member 120 can slide up and down along the connecting section 112. When it slides close to the protruding section 111, it can cooperate with the protruding section 111. When it slides away from the protruding section, the two can separate from each other. The second direction is opposite to the first direction. Figure 5 In the direction from top to bottom.

[0071] It can be understood that after the installation is completed, the protruding section 111 is located in the accommodating section 212, and the sliding member 120 can be located in the accommodating groove 211 outside the accommodating section 212. Fig. 7A If the connecting member 110 continues to move upward relative to the receiving groove 211 along the first direction, the sliding member 120 can push the telescopic member 220 so that the telescopic member 220 retracts into the installation groove 213. At this time, the sliding member 120 can move upward to the receiving section 212, such as Figure 7B As shown, the telescopic member 220 can also extend out of the mounting slot 213 again under the action of its own elastic force. Then, the connecting member 110 can be moved outward relative to the receiving slot 211 along the second direction, as shown in FIG. Figure 7C In the embodiment, due to the obstruction of the telescopic member 220 , the protruding section 111 first moves relative to the sliding member 120 , so that the protruding section 111 cooperates with the sliding member 120 .

[0072] like Fig.7D As shown, in the state where the two are matched, if the connecting member 110 continues to be moved along the second direction, the sliding member 120 can push the telescopic member 220, so that the telescopic member 220 retracts to the installation groove 213, and due to the thrust of the telescopic member 220 on the sliding member 120, the protruding section 111 and the sliding member 120 remain matched, as shown in FIG. Fig. 7E As shown, after the sliding member 120 is separated from the accommodating section 212 , the protruding section 111 may also follow the sliding member 120 to leave the accommodating section 212 , so as to realize the disassembly of the binding belt 30 .

[0073] In this embodiment, the sliding member 120 is used to push the connecting member 110 along the first direction first, and then pull the connecting member 110 along the second direction to achieve the disassembly of the strap. Compared with the fixed ring method in the related art, the disassembly is quick and convenient. After the strap 30 is disassembled, only the first component or the second component is retained on the device body. The first component and the second component do not need to be provided with straps, so they are not limited by the width of the strap, the volume can be made smaller, and the aesthetics can be improved. In addition, the first component or the second component can be fixed on the device body and will not shake relative to the device body 20, so as not to scratch other objects, thereby improving safety.

[0074] Understandably, Figure 5 It can be an orientation diagram when the connecting device 10 is installed or removed, that is, the direction of gravity can be opposite to the first direction, so that Figure 6A-6C During the installation process, the sliding member 120 can be separated from the protruding section 111 by its own gravity, so that it will not move into the accommodating section 212. 7A to 7E During the disassembly process, Figure 7B, the sliding member 120 can be pressed against the telescopic member 220 under the action of gravity, and by adjusting the elastic force of the telescopic member 220, the position of the telescopic member 220 can be kept unchanged in the state of the figure. Fig. 7E When the sliding member 120 is separated from the accommodating section 212 , it can be separated from the protruding section 111 under the action of gravity. However, since the sliding member 120 has opened a sufficient opening for the protruding section 111 , the protruding section 111 is separated from the accommodating section 212 .

[0075] In some embodiments, the sliding member 120 includes a first section 121 and a second section 122 connected in sequence along a first direction, and with a cross-section perpendicular to the first direction as a cross-section, the cross-sectional area of ​​the second section 122 gradually decreases along the first direction; a first groove 1111 is provided at one end of the protruding section 111 facing the sliding member 120, and the second section 122 can be accommodated in the first groove 1111 so that the protruding section 111 cooperates with the sliding member 120.

[0076] like Figure 4 The sliding member 120 includes an upper second section 122 and a lower first section 121, and the cross-sectional area of ​​the second section increases from top to bottom so that Fig. 7A In the embodiment, the second section 122 can push the telescopic member 220 , thereby causing the sliding member 120 to move into the interior of the accommodating section 212 .

[0077] A first groove 1111 is provided at the bottom of the protruding section 111 . The cooperation between the protruding section 111 and the sliding member 120 may mean that the protruding section 111 is accommodated in the first groove 1111 , and the protruding section 111 abuts against the groove wall of the first groove 1111 .

[0078] like Figure 7C It can be understood that the area of ​​the region enclosed by the contour of the lowest end of the first surface 1112 can be slightly smaller than or equal to the area of ​​the region enclosed by the contour of the lowest end of the second section 122, that is, after the protruding section 111 is accommodated in the first groove 1111, the maximum position of the contour of the second section 122 can be the maximum position of the contour of the whole after matching, which is beneficial to the disassembly process of the strap, and the second section 122 can open up a larger diameter for the protruding section 111, so as to facilitate the protruding section 111 to detach from the accommodating section 212.

[0079] In some embodiments, the second section 122 is connected to the first groove 1111 by shape fit, that is, the surface of the second section 122 can fit the groove wall of the first groove 1111, and the two have a better fit effect and are not easy to shake in the horizontal direction.

[0080] In other embodiments, the second section 122 may not completely fit the groove wall of the first groove 1111, as long as the maximum contour position of the second section 122 can be the maximum contour position of the entire body after fitting after the protruding section 111 is accommodated in the first groove 1111.

[0081] In some embodiments, Figure 4 , the cross-sectional area of ​​the first section 121 gradually increases along the first direction.

[0082] The first section 121 can be a structure with a small bottom and a large top. Combined with the shape of the second section 122, the position where the sliding member 120 has the largest cross section is the connecting position of the first section 121 and the second section 122, so that FIG. 7C to FIG. 7D In the state shown, the first section 121 can convert the force of the user pulling the connecting member 110 along the second direction into a component force along the horizontal direction perpendicular to the second direction, and the component force can push the telescopic member 220 to move the telescopic member 220 to the inside of the installation groove 213, which helps the sliding member 120 to disengage from the accommodating section 212.

[0083] In some embodiments, Figure 4 The connecting member 110 also includes a supporting segment 113 connected to one end of the connecting segment 112 away from the protruding segment 111, the supporting segment 113 protrudes from the peripheral side surface of the connecting segment 112, and the supporting segment 113 can be accommodated in the accommodating groove 211, and the sliding member 120 can move between the supporting segment 113 and the protruding segment 111.

[0084] The support segment 113 and the connection segment 112 may be integrally formed, or the support segment 113 and the connection segment 112 may be assembled by common connection methods, such as screw connection, welding, or bonding.

[0085] The size of the support section 113 can be smaller than the size of the accommodating groove 211, so that the support section 113 can also be accommodated in the accommodating groove 211. The support section 113 protrudes from the peripheral side of the connecting section 112. The support section 113 and the protruding section 111 can be used to limit the end points of the sliding path of the sliding member 120 respectively, so that the sliding member 120 can slide relative to the connecting section 112 between the support section 113 and the protruding section 111.

[0086] like Fig. 7A The sliding member 120 can be pressed against the supporting section 113 by the telescopic member 220 , so that the sliding member 120 can remain relatively fixed with the connecting member 110 , and can move along the first direction simultaneously with the connecting member 110 , thereby pushing the telescopic member 220 away.

[0087] In some embodiments, the sliding member 120 is an annular member sleeved outside the connecting section 112 , has a simple structure, is easy to process, and the movement of the sliding member 120 relative to the connecting section 112 is smoother.

[0088] In some embodiments, Figure 5 One end of the telescopic member 220 has a first inclined surface 221. When the telescopic member 220 is extended to the point where the first inclined surface 221 protrudes from the inner wall, the dimension of the first inclined surface 221 protruding from the inner wall gradually increases along the first direction.

[0089] The first inclined surface 221 is one end of the telescopic member 220 away from the bottom of the installation groove 213. It can be understood that when the telescopic member 220 is not subjected to external force, the first inclined surface 221 protrudes from the inner wall of the accommodating groove 211, and its protruding size gradually increases from bottom to top, so that the diameter of the accommodating groove 211 surrounded by the position of the telescopic member 220 gradually decreases along the first direction.

[0090] Under the action of the first inclined surface 221 , during the installation of the binding belt 30 , the protruding section 111 can more easily push the telescopic member 220 , and the operation is more labor-saving.

[0091] In some embodiments, Figure 2 As shown, the telescopic member 220 includes a telescopic portion 222 and an elastic portion 223 , one end of the elastic portion 223 abuts against the bottom of the mounting slot 213 , the other end of the elastic portion 223 is connected to the telescopic portion 222 , and the first inclined surface 221 is arranged at one end of the telescopic portion 222 away from the elastic portion 223 .

[0092] Among them, the elastic part 223 can be an elastic block or spring that can be deformed under the action of external force, such as a coil spring, so as to provide elastic force. The telescopic part 222 can be a block structure that is not easy to deform, so as to facilitate abutment against the protruding section 111 and the sliding part 120, and then the installation and removal of the strap can be achieved by relying on the interaction force.

[0093] The telescopic member 220 provided in this embodiment can be telescopic and has a simple structure, thereby reducing costs.

[0094] In some embodiments, there are multiple telescopic members 220 , and the multiple telescopic members 220 are arranged at equal intervals along the circumference of the accommodating groove 211 .

[0095] like Figure 2 There can be two mounting grooves 213, the number of which is the same as the number of telescopic members 220. Two telescopic members 220 can be installed in the two mounting grooves respectively, and the two telescopic members 220 can be symmetrically arranged, so that the acting force between the sliding member 120 and the telescopic member 220 or between the protruding section 111 and the telescopic member 220 can be more uniform, which is beneficial to the stability of relative movement.

When installing the strap, the installation of the strap and the device body can be realized by only aligning the connecting member with the receiving groove, and then moving the connecting member relative to the receiving groove along the first direction, and the operation is convenient and simple.
