Description

Technical Field

[0001] The present application relates to the technical field of electronic devices, and in particular to a head-mounted display mechanism and a head-mounted device. Background Art

[0002] With the maturity of VR (Virtual Reality) technology, VR devices have begun to be popularized among individual users, and more and more people have begun to use VR devices for work, entertainment or socializing. At present, in order to facilitate users to view the external environment, the displays of most VR devices can be flipped so that they can be opened from the front of the user's eyes when the user views the external environment. At the same time, the display will also generate a certain resistance when flipping, so as to provide the user with a damped rotation feel. For example, the flip structure of a common display generally uses an interference fit to generate friction to provide a damped feel for the flipping of the display. However, the interference fit method of generating friction requires extremely high processing accuracy of the parts of the flip structure, resulting in great difficulty in manufacturing the flip structure and low yield rate, which is not conducive to reducing the production cost of the flip structure. Summary of the invention

[0004] On the other hand, the present application also provides a display mechanism, which includes: a display component and a flip component, and the flip component includes: a connecting shaft, a clamping piece connected to one end of the connecting shaft, and a rotating piece and an elastic piece sleeved on the connecting shaft; wherein the rotating piece is rotatably connected to the connecting shaft and connected to the display component, and the display component is configured to flip as the rotating piece rotates; the elastic piece is located on the side of the rotating piece away from the clamping piece, and is configured to generate an elastic force to press the rotating piece against the clamping piece.

[0005] The present application also provides a head-mounted device, which includes: a wearing mechanism and the above-mentioned display mechanism; wherein the wearing mechanism is connected to the other opposite end of the connecting axis away from the clamping member, and the display component is configured to flip relative to the wearing mechanism as the rotating member rotates.

[0006] The flip assembly provided by the present application is provided with a clamping piece at one end of the connecting shaft, and a rotating piece and an elastic piece sleeved on the connecting shaft, and the elastic piece is also located on the side of the rotating piece away from the clamping piece, and generates elastic force to press the rotating piece against the clamping piece, so that the rotating piece rotatably connected to the connecting shaft can generate resistance by friction with the clamping piece when rotating, so as to provide a damping feeling for the external structure (such as a display) connected and linked to the rotating piece. In such a setting, since the damping feeling is brought about by the elastic piece pressing the rotating piece against the clamping piece to generate resistance by friction, the machining accuracy required for the rotating piece and the connecting shaft is low, which is conducive to reducing the manufacturing difficulty of the flip assembly, and improving the yield rate of the flip assembly, so as to reduce the manufacturing cost of the flip assembly.

Figure 3 yes Figure 2 The middle part is a schematic diagram of the connection structure between the display component 110 and the flip component 120.

[0019] The head mounted device 10 provided in the embodiment of the present application can be worn on the user's head and can realize the function of virtual reality or augmented reality in front of the user's eyes. The following is only an example of the head mounted device 10 being used to realize the function of virtual reality. Figure 1 As shown, the head-mounted device 10 includes: a display mechanism 100 and a wearing mechanism 200. Among them, the display mechanism 100 can be connected to the wearing mechanism 200, and the user can wear the display mechanism 100 on the head through the wearing mechanism 200. At the same time, when the user wears the display mechanism 100 on the head, the display mechanism 100 can be located in front of the user's eyes, and the display mechanism 100 can emit light to the user's eyes for imaging to achieve the function of virtual reality. In addition, the display mechanism 100 is also rotatably connected to the wearing mechanism 200, and can be flipped relative to the wearing mechanism 200 after rotation, so that the display mechanism 100 can be opened from the front of the user's eyes, so that the user can view the external environment when wearing the head-mounted device 10. In this embodiment, the components of the display mechanism 100 can have the advantages of low manufacturing difficulty and high yield rate, which is conducive to reducing the production cost of the display mechanism 100.

[0020] The display mechanism 100 is worn in front of the user's eyes and is used to realize the function of virtual reality, and the display mechanism 100 is also rotatably connected to the wearing mechanism 200. Figure 1 to Figure 2 As shown, the display mechanism 100 includes: a display component 110 and a flip component 120. Among them, the display component 110 is connected to the flip component 120, and the display component 110 can be located in front of the user's eyes, and emit light to the user's eyes for imaging to achieve the function of virtual reality. The flip component 120 is connected to the wearing mechanism 200, and is used to realize the rotational connection between the display component 110 and the wearing mechanism 200, so that the display component 110 can be flipped relative to the wearing mechanism 200, so that the user can turn over the display component 110 to view the external environment. In this embodiment, the flip component 120 can have the advantages of low manufacturing difficulty and high yield rate, which is conducive to reducing the production cost of the flip component 120.

[0021] The display component 110 can be worn in front of the user's eyes and used to realize the function of virtual reality. For example, the display component 110 can have an optical machine and a display lens (waveguide), and the optical machine can be used to emit image light, and the display lens can be used to transmit the image light emitted by the optical machine to the user's eyes for imaging, so as to realize the function of virtual reality. At the same time, the display component 110 can also have functional components such as a camera, a speaker, a laser emitter, and an inertial sensor to increase the diversity of the functions of the display component 110. In addition, in order to install the aforementioned various functional components, the display component 110 can also have a housing 111 (such as Figure 2As shown), the housing 111 can be used to install and protect the aforementioned functional components. In this embodiment, the specific layout positions of the aforementioned functional components on the housing 111 can be adaptively adjusted according to design requirements, and this embodiment does not limit this.

[0022] The display assembly 110 is also connected to the flip assembly 120, and can be rotatably connected to the wearing mechanism 200 through the flip assembly 120, so that the display assembly 110 can be flipped in front of the user's eyes to facilitate the user to view the external environment. Figures 2 to 3 As shown, the display assembly 110 may be provided with a connecting bracket 112 located on the housing 111, and the connecting bracket 112 is used to connect with the flip assembly 120, so that the display assembly 110 can be flipped through the flip assembly 120. Considering the heavy weight of the display assembly 110, the connecting bracket 112 is preferably fastened to the flip assembly 120 by screws or bolts, so as to ensure sufficient connection strength between the connecting bracket 112 and the flip assembly 120, and realize the detachable connection between the connecting bracket 112 and the flip assembly 120. In this embodiment, in addition to being a structural member independent of the housing 111, the connecting bracket 112 may also be a part of the housing 111. That is, the display assembly 110 may also be directly connected to the flip assembly 120 through the housing 111.

[0023] Optionally, the connecting bracket 112 and the flip assembly 120 may be connected by one or more methods such as welding, clamping, and bonding, as long as the connecting bracket 112 and the flip assembly 120 have sufficient connection strength, which is not limited in this embodiment.

[0024] Optionally, in addition to the above embodiments, the specific structure of the display component 110 can also be adjusted according to design requirements. It only needs that the display component 110 can be connected to the flip component 120 and can be flipped by the flip component 120. This embodiment does not limit this.

[0025] All directional indications (such as up, down, left, right, front, back...) in the embodiments of the present application are only used to explain the relative positional relationship, movement, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication also changes accordingly. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but optionally also includes steps or units that are not listed, or optionally also includes other steps or units inherent to these processes, methods, products or devices.

[0026] See also Figures 4 to 6 , Figure 4 yes Figure 3 The exploded structural diagram of the flip assembly 120 is shown in FIG. Figure 5 yes Figure 4 A schematic diagram of the connection structure of the middle connecting shaft 121, the clamping member 122, the rotating member 123 and the elastic member 124, Figure 6 yes Figure 1 A schematic diagram of the partial cross-sectional structure of the middle flip assembly 120 along V-V.

[0027] The flip assembly 120 is connected to the connecting bracket 112 and the wearing mechanism 200 respectively, and is used to realize the rotation connection between the connecting bracket 112 and the wearing mechanism 200. Figures 4 to 5 As shown, the flip assembly 120 includes: a connecting shaft 121, a clamping member 122, a rotating member 123 and an elastic member 124. Among them, the connecting shaft 121 is connected to the wearing mechanism 200, and the clamping member 122 is arranged on the end of the connecting shaft 121. The rotating member 123 is sleeved on the connecting shaft 121 and is rotationally connected to the connecting shaft 121, and the connecting bracket 112 is also linked with the rotating member 123, so that the connecting bracket 112 can flip with the rotation of the rotating member 123. The elastic member 124 is also sleeved on the connecting shaft 121 and is located on the side of the rotating member 123 away from the clamping member 122, and the elastic member 124 also generates elastic force to press the rotating member 123 against the clamping member 122, so that the rotating member 123 can rub against the clamping member 122 when rotating to generate resistance, so as to provide a damping feel for the flipping of the connecting bracket 112.

[0028] After long-term research by the inventor, it is found that the flipping structure of some schemes uses an interference fit shaft core and a sleeve to respectively connect the wearing mechanism 200 and the display assembly 110 (connecting bracket 112), and uses the rotation of the sleeve to rub against the shaft core to generate resistance, so as to provide a damping feel for the flipping of the display assembly 110. However, the above scheme has extremely high requirements for the processing accuracy of the shaft core and the sleeve. If the accuracy is insufficient, the shaft core and the sleeve are prone to being too tight or too loose, which seriously affects the damping feel of the display assembly 110 when flipping. The high-precision processing requirements will not only increase the processing difficulty of the parts, but also affect the yield rate of the parts, which is not conducive to reducing the production cost of the flipping structure. At the same time, since the shaft core and the sleeve are rubbed to generate resistance by interference fit, the shaft core and the sleeve are very likely to wear after long-term friction, and the resistance generated by the friction between the shaft core and the sleeve will gradually decrease until it disappears as the degree of wear increases, which is not conducive to maintaining the duration and effect of the damping feel when the display assembly 110 is flipped.

[0029] In order to solve the above technical problems, the flip assembly 120 provided in the embodiment of the present application is provided with a clamping member 122 at the end of the connecting shaft 121, and a rotating member 123 and an elastic member 124 sleeved on the connecting shaft 121, and the elastic member 124 is also located on the side of the rotating member 123 away from the clamping member 122, and generates elastic force to press the rotating member 123 against the clamping member 122, so that the rotating member 123 rotatably connected to the connecting shaft 121 can generate resistance by friction with the clamping member 122 when rotating, so as to provide a damping feel for the connecting bracket 112 (equivalent to the display assembly 110) connected and linked with the rotating member 123. In such a configuration, since the damping feel is brought about by the elastic member 124 pressing the rotating member 123 against the clamping member 122 to generate resistance by friction, the machining accuracy required for the rotating member 123 and the connecting shaft 121 is low, which is conducive to reducing the manufacturing difficulty of the flip assembly 120, and improving the yield rate of the flip assembly 120, so as to reduce the manufacturing cost of the flip assembly 120. At the same time, even after long-term use, the elastic force generated by the elastic member 124 can compensate for the wear caused by the friction between the rotating member 123 and the clamping member 122, which is beneficial to maintaining the duration and effect of the damping feel when the display assembly 110 is flipped.

[0030] Specifically, one end of the connecting shaft 121 can be connected to the clamping member 122, and the other opposite end can be connected to the wearing mechanism 200, and is sleeved with a rotating member 123 and an elastic member 124. Figures 4 to 6 As shown, the connecting shaft 121 includes: a main body 1211 and a protruding portion 1212 which are coaxially arranged. One end of the main body 1211 is connected to the clamping member 122, and the main body 1211 can be sleeved on the rotating member 123 and the elastic member 124, and is rotatably connected to the rotating member 123. The protruding portion 1212 is connected to the other opposite end of the main body 1211, and is arranged protruding from the circumferential side of the main body 1211 in the radial direction R of the main body 1211 (equivalent to the radial direction of the connecting shaft 121), and the protruding portion 1212 is also arranged opposite to the clamping member 122. At the same time, the rotating member 123 and the elastic member 124 are located between the protruding portion 1212 and the clamping member 122, and the elastic member 124 is also respectively in contact with the protruding portion 1212 and the rotating member 123 to generate elastic force to press the rotating member 123 against the clamping member 122. In this embodiment, the material of the connecting shaft 121 can be plastic, and the main body 1211 and the protruding portion 1212 can be integrally formed by injection molding to reduce the difficulty of manufacturing the connecting shaft 121 and the difficulty of subsequent processing.

[0031] Optionally, the main body 1211 is further provided with an annular groove 12101 on the circumferential side in the radial direction, and the annular groove 12101 is also located at the end of the main body 1211 away from the protruding portion 1212. The annular groove 12101 can be used to accommodate the clamping member 122 and limit the clamping member 122 to reduce the probability of the clamping member 122 being offset by the rotation member 123, thereby improving the connection firmness between the clamping member 122 and the main body 1211.

[0032] Optionally, the connecting shaft 121 may further include: a plug-in portion 1213 coaxially arranged with the main body portion 1211 and the protruding portion 1212. Figures 4 to 6 As shown, the plug-in portion 1213 is arranged on the side of the protrusion 1212 away from the main body 1211, and the plug-in portion 1213 can be inserted into the wearing mechanism 200 to achieve the connection between the connecting shaft 121 and the wearing mechanism 200. At the same time, the protrusion 1212 can also protrude from the plug-in portion 1213 in the radial direction R, so that when the plug-in portion 1213 is inserted into the wearing mechanism 200, the protrusion 1212 can also contact the wearing mechanism 200 and can be engaged with the wearing mechanism 200 to ensure that the plug-in portion 1213 is inserted into place. In this embodiment, the plug-in portion 1213 can also be interference-fitted with the wearing mechanism 200 to improve the assembly firmness of the connecting shaft 121 and the wearing mechanism 200. In addition, the main body 1211, the protrusion 1212 and the plug-in portion 1213 can also be integrally formed by injection molding.

[0033] Optionally, since the plug-in portion 1213 is inserted into the wearing mechanism 200, in order to prevent the plug-in portion 1213 from rotating relative to the wearing mechanism 200, a convex block 12121 is further provided on the side of the protruding portion 1212 facing the wearing mechanism 200, and the wearing mechanism 200 is provided with a groove corresponding to the convex block 12121. The convex block 12121 is located in the groove and can be engaged with the inner wall of the groove to limit the rotation of the plug-in portion 1213 relative to the wearing mechanism 200.

[0034] Optionally, the connecting shaft 121 may be hollow and have a wiring space 12102 that sequentially passes through the main body 1211, the protruding portion 1212, and the plug-in portion 1213. Figure 6 As shown, the wiring space 12102 can be connected to the wearing mechanism 200, so that the display component 110 can be wired through the wiring space 12102 and electrically connected to the wearing mechanism 200.

[0035] The clamping member 122 is disposed in the annular groove 12101 and surrounds the circumference of the main body 1211. Figures 4 to 6As shown, the clamping member 122 is also protruded from the peripheral side of the main body 1211 in the radial direction R, that is, the clamping member 122 is also protruded from the annular groove 12101, so that the clamping member 122 can be arranged opposite to the protruding portion 1212. Among them, the clamping member 122 can be a retaining spring, and the clamping member 122 is also interference fit with the main body 1211, and / or is fixed to the main body 1211 by laser welding, so as to improve the connection firmness between the clamping member 122 and the main body 1211, and reduce the probability of the clamping member 122 being offset by the rotating member 123. Of course, in addition to the retaining spring, the clamping member 122 can also be other similar structures, and the clamping member 122 can also be connected to the main body 1211 by other fixing methods. For example, the design of the annular groove 12101 can also be omitted, and the clamping member 122 can also be directly welded to the peripheral side of the main body 1211.

[0036] The rotating member 123 is sleeved on the main body 1211 and is located between the protruding portion 1212 and the fastening member 122. Figures 4 to 6 As shown, the rotating member 123 is also rotatably connected to the main body 1211, and can rotate with the extension direction of the main body 1211 as the axial direction. At the same time, the rotating member 123 can also be linked with the connecting bracket 112. That is, the connecting bracket 112 can be turned over with the rotation of the rotating member 123, so that the display assembly 110 can have a damping feeling generated by the friction between the rotating member 123 and the clamping member 122 when turning over. In this embodiment, the rotating member 123 is preferably wear-resistant to increase the service life of the rotating member 123.

[0037] The elastic member 124 is sleeved on the main body 1211 and is located between the rotating member 123 and the protruding portion 1212, and the elastic member 124 is also respectively in contact with the rotating member 123 and the protruding portion 1212 to generate elastic force to press the rotating member 123 against the clamping member 122. The elastic member 124 can be a spring, such as any one of a square spring, a disc spring or a round spring, and the opposite ends of the elastic member 124 can be in contact with the rotating member 123 and the protruding portion 1212 respectively. At the same time, during the assembly process, a certain pressure can be applied to the elastic member 124 in advance so that the elastic member 124 is in a compressed state, and then the rotating member 123 and the clamping member 122 are assembled on the main body 1211 to ensure that the elastic member 124 can generate elastic force to press the rotating member 123 against the clamping member 122. Optionally, in addition to the spring, the elastic member 124 can also be other structural members that can generate elastic force. For example, the elastic member 124 may also be an elastic pad made of elastic materials such as silicone or rubber, and the elastic pad may also be sleeved on the main body 1211 and compressed to generate elastic force to press the rotating member 123 against the clamping member 122 .

[0038] Optionally, the flip assembly 120 may also be provided with a connecting shell 125. Figure 4 and Figure 6 As shown, the connecting shaft 121 can be inserted into the connecting shell 125, and the clamping member 122, the rotating member 123 and the elastic member 124 are all located in the connecting shell 125, so that the connecting shell 125 can shield the clamping member 122, the rotating member 123 and the elastic member 124. At the same time, the connecting shell 125 can also be connected to the rotating member 123 and the connecting bracket 112 respectively, and is rotatably connected to the connecting shaft 121, and the connecting shell 125 can rotate with the rotation of the rotating member 123 to realize the linkage of the connecting bracket 112 and the rotating member 123. For example, the rotating member 123 can be provided with a socket, and the connecting shell 125 can be provided with a pin inserted in the socket to realize the connection between the rotating member 123 and the connecting shell 125.

[0039] Optionally, the connection shell 125 and the rotating member 123 may be connected in other ways, as long as the two can be linked, which is not limited in this embodiment. Optionally, the design of the connection shell 125 may be omitted, and the connection bracket 112 may be directly connected to the rotating member 123, as long as the connection bracket 112 can be linked with the rotating member 123, which is not limited in this embodiment.

[0040] Optionally, the connection shell 125 can also cooperate with the connection shaft 121 to achieve the stationary state of the display assembly 110 after flipping. Figures 5 and 6 As shown, a slide groove 12103 is provided on one side of the protruding portion 1212 facing the rotating member 123, and the slide groove 12103 also penetrates the protruding portion 1212 and protrudes from one side of the main body 1211 in the radial direction R. At the same time, the connecting shell 125 is provided with a sliding structure 1251 located in the slide groove 12103, and the sliding structure 1251 can slide in the slide groove 12103 as the connecting shell 125 rotates. In addition, after the sliding structure 1251 slides to a preset position in the slide groove 12103, the sliding structure 1251 can also stay in the slide groove 12103 to achieve the flipping and staying of the display assembly 110.

[0041] Optionally, there may be two preset positions, and when the sliding structure 1251 is located at the first preset position for residence, the display component 110 may be located in front of the user's eyes, and the sliding structure 1251 may limit the display component 110 to reduce the probability of the display component 110 shaking due to external forces. When the sliding structure 1251 slides to the second preset position for residence, the display component 110 may be flipped open from in front of the user's eyes, and the sliding structure 1251 may also limit the display component 110 to maintain the flipped-open state of the display component 110, thereby facilitating the user to view the external environment. It is understandable that the foregoing description of the preset positions is for exemplary purposes only, and the selection and number of preset positions may be designed as required, and this embodiment does not limit this.

[0042] The terms "first", "second", and "third" in this application are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, a feature defined as "first", "second", and "third" may explicitly or implicitly include at least one of the features.

[0043] Optionally, in order to achieve the retention of the sliding structure 1251 at the preset position, a limiting groove 12104 may be provided on the bottom wall of the slide groove 12103. When the sliding structure 1251 slides in the slide groove 12103, the sliding structure 1251 can abut against the bottom wall of the slide groove 12103 and produce a certain elastic deformation (such as a spring or a combination structure of a spring and a ball head). When the sliding structure 1251 slides to the preset position, the sliding structure 1251 can be snapped into the limiting groove 12104 under the action of elastic force, and snapped with the inner wall of the limiting groove 12104 in the sliding direction to limit the sliding of the sliding structure 1251, thereby achieving the retention of the sliding structure 1251. Similarly, when the user flips the display assembly 110, the force applied by the user can overcome the clamping force between the sliding structure 1251 and the limiting groove 12104, so that the sliding structure 1251 can be elastically deformed by the side wall of the limiting groove 12104 and exit the limiting groove 12104 to release the stationary state of the sliding structure 1251. In this embodiment, the number of the limiting grooves 12104 is preferably two. Of course, the limiting groove 12104 can also be single or more than two, which is not limited in this embodiment.

[0044] Optionally, the positions of the sliding structure 1251 and the sliding groove 12103 may also be interchanged. That is, the protruding portion 1212 is provided with the sliding structure 1251, and the connecting shell 125 is provided with the sliding groove 12103, and the matching relationship between the sliding structure 1251 and the sliding groove 12103 after the positions are interchanged is the same or similar to the matching relationship before the interchange, which will not be described in detail.

[0045] The flip assembly 120 provided in the embodiment of the present application is provided with a clamping member 122 at one end of the connecting shaft 121, and a rotating member 123 and an elastic member 124 sleeved on the connecting shaft 121, and the elastic member 124 is also located on the side of the rotating member 123 away from the clamping member 122, and generates elastic force to press the rotating member 123 against the clamping member 122, so that the rotating member 123 rotatably connected to the connecting shaft 121 can generate resistance by friction with the clamping member 122 when rotating, so as to provide a damping feeling to the display assembly 110 connected and linked with the rotating member 123. In such a configuration, since the damping feeling is brought about by the elastic member 124 pressing the rotating member 123 against the clamping member 122 to generate resistance by friction, the machining accuracy required for the rotating member 123 and the connecting shaft 121 is low, which is conducive to reducing the manufacturing difficulty of the flip assembly 120, and improving the yield rate of the flip assembly 120, so as to reduce the manufacturing cost of the flip assembly 120.

[0046] Optionally, in addition to being applied to the head-mounted device 10 for realizing virtual reality, the flip component 120 can also be used in other devices with damped tactile rotation requirements, such as head-mounted lighting equipment, head-mounted camera equipment, and head-mounted detection equipment, etc., which is not limited in this embodiment.

[0047] Please combine Figure 1 and Figure 6 See also Figure 7 , Figure 7 yes Figure 1 Schematic diagram of the structure of the wearing mechanism 200.

[0048] The wearing mechanism 200 is connected to the flip assembly 120, and the user can wear the display mechanism 100 on the head through the wearing mechanism 200. Figure 1 and Figure 7 As shown, the wearing mechanism 200 may include: a telescopic component 210 and a headrest component 220. The telescopic component 210 may be connected to the headrest component 220, and together with the headrest component 220, a head wearing space 202 is formed, and the telescopic component 210 is also connected to the flip component 120. The headrest component 220 is also arranged opposite to the display component 110, and the telescopic component 210 can be telescoped to adjust the distance between the headrest component 220 and the display component 110.

[0049] Further, the telescopic assembly 210 may include: a fixed rod 211 and a sliding rod 212. The fixed rod 211 may be connected to the headrest assembly 220, and the sliding rod 212 may be slidably connected to the fixed rod 211 to realize the telescopic function of the telescopic assembly 210, and the sliding rod 212 is also connected to the connecting shaft 121. The sliding rod 212 may be arranged in a hollow shape, and a receiving space 2121 connecting the fixed rod 211 and the connecting shaft 121 is formed, and the plug-in portion 1213 of the connecting shaft 121 may be inserted into the receiving space 2121, so that the receiving space 2121 can also be connected to the wiring space 12101 for wiring. The sliding rod 212 is also connected to the side of the protruding portion 1212 away from the rotating member 123, and is provided with a groove matched with the protruding block 12121 to realize the positioning connection between the sliding rod 212 and the protruding portion 1212. In this embodiment, the number of telescopic components 210 can be two groups, and the two groups of telescopic components 210 can be respectively connected to the opposite sides of the headrest component 220. At the same time, in order to cooperate with the two groups of telescopic components 210, the number of flip components 120 can also be two groups, so as to be connected to the two groups of telescopic components 210. In addition, the two groups of flip components 120 can also share the same connection shell 125 to reduce the number of structural parts required for the head mounted device 10.

[0050] Furthermore, the headrest assembly 220 can be worn behind the user's head and support the user's head. Among them, the headrest assembly 220 can also be installed with functional devices (such as batteries) required for the head-mounted device 10, as well as a driving structure for controlling the telescopic assembly 210 to telescope. At the same time, the fixed rod 211 can also be set in a hollow shape and connected to the headrest assembly 220, so that the headrest assembly 220 can be wired through the fixed rod 211 and the sliding rod 212 to achieve electrical connection between the headrest assembly 220 and the display assembly 110. It can be understood that the headrest assembly 220 and the telescopic assembly 210 are only exemplary illustrations of the wearing mechanism 200. In some embodiments, the wearing mechanism 200 can also be adaptively adjusted according to design requirements, which is not limited in this embodiment.

[0051] The flip assembly 120 provided in the embodiment of the present application is provided with a clamping member 122 at one end of the connecting shaft 121, and a rotating member 123 and an elastic member 124 sleeved on the connecting shaft 121, and the elastic member 124 is also located on the side of the rotating member 123 away from the clamping member 122, and generates elastic force to press the rotating member 123 against the clamping member 122, so that the rotating member 123 rotatably connected to the connecting shaft 121 can generate resistance by friction with the clamping member 122 when rotating, so as to provide a damping feeling to the display assembly 110 connected and linked with the rotating member 123. In such a configuration, since the damping feeling is brought about by the elastic member 124 pressing the rotating member 123 against the clamping member 122 to generate resistance by friction, the machining accuracy required for the rotating member 123 and the connecting shaft 121 is low, which is conducive to reducing the manufacturing difficulty of the flip assembly 120, and improving the yield rate of the flip assembly 120, so as to reduce the manufacturing cost of the flip assembly 120.
