[0002] This application claims priority to Chinese Patent Application No. 202510230400.X, filed in China on February 28, 2025, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application belongs to the field of electronic device technology, specifically relating to a head-mounted display device. Background Technology

[0004] With the advancement of technology and the widespread adoption of smart devices, people have increasingly higher demands for these devices. Head-mounted extended reality (XR) devices can bring better experiences to people's entertainment and work.

[0005] Currently, protective layers (also known as face shields) are unavoidable in the lens and mask designs of head-mounted displays. These layers provide aesthetic appeal and occasionally offer light-blocking benefits. However, during lens movement, the protective layer creates resistance, leading to increased motor power consumption. Summary of the Invention

[0006] The purpose of this application is to provide a head-mounted display device that can solve the problem in related technologies where the motor power consumption increases due to the resistance generated by the protective layer on the lens movement when the lens moves.

[0009] A protective layer is connected to both the lens and the device housing.

[0010] The scaling structure connected to the protective layer;

[0011] When the lens moves toward the target direction relative to the device housing, the scaling structure causes the first part of the protective layer to contract and the second part of the protective layer to release. The first part of the protective layer is the part that is moved into the scaling structure during the movement, and the second part of the protective layer is the part that is moved out of the scaling structure during the movement.

One of the second roll mechanisms is arranged on the side of the first lens away from the first edge, and the other second roll mechanism is arranged on the side of the second lens away from the second edge.

[0015] In some embodiments, when the target direction is a first direction, the first roller mechanism rotates in the direction of rolling up the edge of the protective layer, causing a first portion of the protective layer to contract, and the second roller mechanism rotates in the direction of releasing the edge of the protective layer, causing a second portion of the protective layer to release; or...

[0019] When the target direction is the first direction, the first rotating shaft rotates in the direction of rolling up the edge of the protective layer through the first energy storage component, causing the first part of the protective layer to shrink.

[0020] When the target direction is the second direction, the first rotating shaft rotates in the direction of releasing the edge of the protective layer through the first energy storage component, so that the second part of the protective layer is released.

[0021] In some embodiments, the first energy storage component is a deformable spring.

[0022] In some embodiments, the second reel mechanism includes:

[0023] A second rotating shaft is connected to the protective layer; a second energy storage component is disposed at both ends of the second rotating shaft and connects the second rotating shaft and the lens;

[0024] When the target direction is the first direction, the second rotating shaft of the second energy storage component rotates in the direction of releasing the edge of the protective layer, thereby releasing the second part of the protective layer;

[0025] When the target direction is the second direction, the second rotating shaft rotates in the direction of rolling up the edge of the protective layer through the second energy storage component, causing the first part of the protective layer to shrink.

[0026] In some embodiments, the second energy storage component includes a second support member and a second energy storage member. The second support member is sleeved on the second rotating shaft and connected to the lens. The second energy storage member is connected to the end of the second rotating shaft and the lens, respectively.

[0027] In some embodiments, the second energy storage component is a deformable spring.

[0028] In some embodiments, the device housing includes a first frame and a second frame that is fastened to the first frame;

[0029] The lens and the moving adjustment mechanism are disposed within the first frame;

[0030] The protective layer is connected to the lens and the second frame, respectively.

[0031] In some embodiments, the moving adjustment mechanism includes: a drive motor;

[0032] The drive motor is connected to the lens and is used to drive the lens to move.

[0034] The first drive shaft and the second drive shaft are distributed on both sides of the lens and are parallel to the length direction of the device housing; the first drive shaft is connected to the lens, and the second drive shaft is connected to the lens.

[0035] The drive motor provides driving force to the lens, causing the lens to move relative to the device housing toward the target direction via the first drive shaft and the second drive shaft.

[0036] In this embodiment, a movable adjustment mechanism disposed within the device housing is connected to a lens within the device housing to control the movement of the lens; a protective layer is connected to both the lens and the device housing; a scaling structure is connected to the protective layer; wherein, when the lens moves relative to the device housing toward the target direction, the scaling structure causes the first part of the protective layer to contract and the second part of the protective layer to release; the first part of the protective layer is the portion moved into the scaling structure during the movement, and the second part of the protective layer is the portion moved out of the scaling structure during the movement. In this way, when adjusting the distance between the lenses, the scaling structure allows the protective layer to extend and contract freely, thereby reducing the resistance of the protective layer to the movement of the lens and achieving the effect of not affecting the power consumption of the motor.

[0051] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0052] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0053] In its current state, the two lenses of the head-mounted display can move simultaneously inward or outward under the action of the drive motor. When the protective layer retracts inward (i.e., both lenses move inward simultaneously), if the protective layer has weak elasticity, the protective layer on both sides of the temples of the head-mounted display will tighten; similarly, when the protective layer expands outward (i.e., both lenses move outward simultaneously), the protective layer on the center side of the head-mounted display will tighten. This tightening state means that for the same distance of movement, the drive motor needs to provide additional power to the lenses, resulting in increased motor power consumption and affecting the smoothness of lens movement.

[0054] To address the aforementioned technical problems, this application provides a head-mounted display device. The head-mounted display device provided in this application will be described in detail below with reference to Figures 1 to 14, through specific embodiments and application scenarios.

[0055] This application provides a head-mounted display device, including a device housing 1 and lenses (2,3) disposed within the device housing 1, a movement adjustment mechanism 4 disposed within the device housing 1 and connected to the lenses (2,3) respectively; the movement adjustment mechanism 4 is used to control the movement of the lenses (2,3); a protective layer 5 is connected to the lenses (2,3) and the device housing 1 respectively; and a scaling structure 100 connected to the protective layer 5.

[0056] When the lens (2,3) moves toward the target direction relative to the device housing 1, the scaling structure 100 causes the first part of the protective layer 5 to contract and the second part of the protective layer 5 to release; the first part of the protective layer 5 is the part that is moved into the scaling structure 100 during the movement, and the second part of the protective layer 5 is the part that is moved out of the scaling structure 100 during the movement.

[0057] Specifically, lenses (2,3) include a first lens 2 and a second lens 3. It should be understood that the movement of lenses (2,3) relative to the device housing 1 towards the target direction can be: the first lens 2 moves relative to the device housing 1 towards the target direction while the second lens 3 remains stationary; the second lens 3 moves relative to the device housing 1 towards the target direction while the first lens 2 remains stationary; or both the first lens 2 and the second lens 3 move relative to the device housing 1 towards the target direction. The target direction can be a direction in which the first lens 2 and the second lens 3 move closer to each other, a direction in which the first lens 2 and the second lens 3 move further apart, or any other direction.

[0058] In the head-mounted display device of this application embodiment, when adjusting the distance between the lenses, the protective layer can be freely extended and contracted through the scaling structure, thereby reducing the resistance of the protective layer to the movement of the lenses and achieving the effect of not affecting the power consumption of the motor.

[0059] Optionally, the protective layer 5 is a flexible protective layer, that is, made of flexible materials.

[0060] In some embodiments, the scaling structure 100 includes: a first scroll mechanism 6 symmetrically disposed on a first edge 101 and a second edge 102 of the device housing 1, and the first scroll mechanism 6 is connected to the protective layer 5 and the device housing 1 respectively, and the first edge 101 and the second edge 102 are both away from the center of the device housing 1; and a second scroll mechanism 7 symmetrically disposed on a first lens 2 and a second lens 3, the second scroll mechanism 7 being connected to the protective layer 5 and the lenses (2,3) respectively, one of the second scroll mechanisms 7 being disposed on the side of the first lens 2 away from the first edge 101, and the other second scroll mechanism 7 being disposed on the side of the second lens 3 away from the second edge 102.

[0061] In this embodiment, there are two first scroll mechanisms 6 and two second scroll mechanisms 7. Of course, the number of scroll mechanisms included in the scaling structure 100 is not limited to four; this is just an example, and the specific number can be determined as needed and is not specifically limited.

[0062] Wherein, the first edge 101 and the second edge 102 are both far away from the center of the device housing 1. Referring to Figure 1, it can be understood that the first edge 101 and the second edge 102 are close to the temple of the head-mounted display device, respectively.

[0063] Specifically, when the target direction is the first direction, the first roller mechanism 6 rotates in the direction of rolling up the edge of the protective layer 5, causing the first part of the protective layer 5 to contract, and the second roller mechanism 7 rotates in the direction of releasing the edge of the protective layer 5, causing the second part of the protective layer 5 to release; or,

[0064] When the target direction is the second direction, the first reel mechanism 6 rotates in the direction of releasing the edge of the protective layer 5, so that the second part of the protective layer 5 is released; the second reel mechanism 7 rotates in the direction of rolling up the edge of the protective layer 5, so that the first part of the protective layer 5 is contracted, and the second direction is opposite to the first direction.

[0065] It should be understood that the edge of the protective layer 5 refers to the portion of the protective layer 5 along its edge, and the roller mechanism (6,7) is connected to this portion.

[0066] For example, the first direction is the direction in which the first lens 2 and the second lens 3 move away from each other, as shown in Figure 11; the second direction is the direction in which the first lens 2 and the second lens 3 move closer to each other, as shown in Figure 6. As can be seen from Figures 6 and 11, when the first lens 2 and the second lens 3 are in the first direction under the control of the moving adjustment mechanism 4, without the cooperation of the first scroll mechanism 6 and the second scroll mechanism 7, the protective layer 5 near the center of the device housing 1 will be stretched and in a taut state; when the first lens 2 and the second lens 3 are in the second direction under the control of the moving adjustment mechanism 4, without the cooperation of the first scroll mechanism 6 and the second scroll mechanism 7, the protective layers on both sides of the temples of the head-mounted display device will be in a taut state; however, with the first scroll mechanism 6 and the second scroll mechanism 7 provided in this application, when the first lens 2 and the second lens 3 are in the first direction under the control of the moving adjustment mechanism 4, the second scroll mechanism 7 rotates in the direction of releasing the edge of the protective layer 5, causing the second part of the protective layer 5 to be released, thus preventing the protective layer 5 near the center of the device housing 1 from being in a taut state. Simultaneously, as the lens slowly approaches the first roll mechanism 6, the first roll mechanism 6 rotates in the direction of rolling the edge of the protective layer 5, causing the first part of the protective layer 5 to contract, and the protective layer 5 between the lens and the first roll mechanism 6 to stretch. When the first lens 2 and the second lens 3 move in the second direction under the control of the movement adjustment mechanism 4, the first roll mechanism 6 rotates in the direction of releasing the edge of the protective layer 5, causing the second part of the protective layer 5 to release, thus preventing the protective layers 5 on both sides of the temples of the head-mounted display from being in a taut state. At the same time, as the first lens 2 and the second lens 3 slowly approach each other, the second roll mechanism 7 rotates in the direction of rolling the edge of the protective layer 5, causing the first part of the protective layer 5 to contract, and the protective layer 5 between the two lenses to stretch. This process can reduce the resistance of the protective layer to the movement of the lens, achieving the effect of not affecting the power consumption of the motor.

[0067] Referring to Figures 1, 6 and 11, in an optional embodiment, the device housing 1 includes a first frame 11 and a second frame 12 that is fastened to the first frame 11; wherein, the lens (2,3) and the moving adjustment mechanism 4 are disposed within the first frame 11; and the protective layer 5 is connected to the lens (2,3) and the second frame 12 respectively.

[0068] The first frame 11 and the second frame 12 are fastened together, which facilitates the disassembly of the head-mounted display device and is beneficial for the replacement, repair or testing of parts in the future.

[0069] In some embodiments, referring to Figures 2 and 3, and Figures 7 to 10, the first reel mechanism 6 includes: a first rotating shaft 61, the first rotating shaft 61 being connected to the protective layer 5; and a first energy storage component 60 disposed at both ends of the first rotating shaft 61 and connecting the first rotating shaft 61 and the device housing 1.

[0070] When the target direction is the first direction, the first energy storage component 60 and the first rotating shaft 61 rotate in the direction of rolling the edge of the protective layer 5, causing the first part of the protective layer 5 to shrink.

[0071] When the target direction is the second direction, the first energy storage component 60 and the first rotating shaft 61 rotate in the direction of releasing the edge of the protective layer 5, so that the second part of the protective layer 5 is released.

[0072] In some embodiments, the first energy storage component 60 includes a first support member 62 and a first energy storage member 63. The first support member 62 is sleeved on the first rotating shaft 61 and connected to the device housing 1. The first energy storage member 63 is connected to the end of the first rotating shaft 61 and the device housing 1 respectively.

[0073] Corresponding to the above embodiment of the device housing 1 including a first frame 11 and a second frame 12, in this embodiment, a first support member 62 is disposed at both ends of a first rotating shaft 61, connecting the first rotating shaft 61 and the second frame 12, and a first energy storage member 63 is disposed at both ends of a first rotating shaft 61, connecting the first rotating shaft 61 and the second frame 12.

[0074] It should be noted that the first support member 62 is located between the first energy storage member 63 and the protective layer 5.

[0075] When the first lens 2 and the second lens 3 are in their original positions (which can be understood as the positions of the first lens 2 and the second lens 3 when the head-mounted display device is first manufactured), a portion of the edge of the protective layer 5 is wrapped around the first rotating shaft 61 (as shown in Figures 7 and 9); this allows excess protective layer to extend out when the first lens 2 and the second lens 3 move toward the target direction, so as to avoid the protective layer 5 being in a taut state.

[0076] For example, the first direction is the direction in which the first lens 2 and the second lens 3 move away from each other. The first lens 2 and the second lens 3 move from their original positions toward the first direction. The energy stored in the first energy storage component 63 assists the first rotating shaft 61 to rotate toward the edge of the protective layer 5. That is, the energy stored in the first energy storage component 63 provides power for the protective layer 5 to extend and retract (retract).

[0077] The second direction is the direction in which the first lens 2 and the second lens 3 move closer to each other. The first lens 2 and the second lens 3 move from their original positions towards the second direction, and the first rotating shaft 61 rotates towards the edge of the protective layer 5, causing the first energy storage component 63 to store energy. Here, when the first lens 2 and the second lens 3 move from their original positions towards the second direction, the first rotating shaft 61 rotates towards the edge of the protective layer 5, that is, the protective layer extends. This reduces the resistance of the protective layer to the movement of the lenses, achieving the effect of not affecting the power consumption of the motor.

[0078] Specifically, referring to Figure 12, the first support member 62 includes: a connecting portion 621 sleeved on the first rotating shaft 61; and a first support portion 622 and a second support portion 623 located on both sides of the connecting portion 621. The first support portion 622 connects the connecting portion 621 and the device housing 1, and the second support portion 623 connects the connecting portion 621 and the device housing 1. In this way, the first support member 62, with the above structural design, can support the first rotating shaft 61.

[0079] Corresponding to the embodiment of the above-mentioned device housing 1 including a first frame 11 and a second frame 12, the first support part 622 connects the connecting part 621 and the second frame 12, and the second support part 623 connects the connecting part 621 and the second frame 12.

[0080] Optionally, the first energy storage element 63 is a deformable spring. For example, the deformable spring is a spiral spring.

[0081] In some embodiments, referring to Figures 4 and 5, the second reel mechanism 7 includes: a second rotating shaft 71 connected to the protective layer 5; and a second energy storage assembly 70 disposed at both ends of the second rotating shaft 71 and connecting the second rotating shaft 71 and the lens (2,3).

[0082] When the target direction is the first direction, the second energy storage component 70 and the second rotating shaft 71 rotate in the direction of releasing the edge of the protective layer 5, so that the second part of the protective layer 5 is released.

[0083] When the target direction is the second direction, the second energy storage component 70 and the second rotating shaft 71 rotate in the direction of rolling the edge of the protective layer 5, causing the first part of the protective layer 5 to shrink.

[0084] In some embodiments, the second energy storage component 70 includes a second support member 72 and a second energy storage member 73. The second support member 72 is sleeved on the second rotating shaft 71 and connected to the lens (2,3). The second energy storage member 73 is connected to the end of the second rotating shaft 71 and the lens (2,3) respectively.

[0085] It should be noted that the second support member 72 is located between the second energy storage member 73 and the protective layer 5.

[0086] When the first lens 2 and the second lens 3 are in their original positions (which can be understood as the positions of the first lens 2 and the second lens 3 when the head-mounted display device is first manufactured), a portion of the edge of the protective layer 5 is wrapped around the second rotating shaft 71; this allows excess protective layer to extend out when the first lens 2 and the second lens 3 move toward the target direction, so as to avoid the protective layer 5 being in a taut state.

[0087] For example, the first direction is the direction in which the first lens 2 and the second lens 3 move away from each other. When the first lens 2 and the second lens 3 move from their original positions toward the first direction, the second rotating shaft 71 rotates toward the edge of the protective layer 5, causing the second energy storage component 73 to store energy. When the first lens 2 and the second lens 3 move from their original positions toward the first direction, the second rotating shaft 71 rotates toward the edge of the protective layer 5, that is, the protective layer extends. This reduces the resistance of the protective layer to the movement of the lenses, achieving the effect of not affecting the power consumption of the motor.

[0088] The second direction is the direction in which the first lens 2 and the second lens 3 approach each other. The first lens 2 and the second lens 3 move from their original positions toward the second direction. The energy stored in the second energy storage component 73 assists the second rotating shaft 71 to rotate toward the edge of the rolling protective layer 5. In other words, the energy stored in the second energy storage component 73 provides power for the protective layer 5 to extend and retract (retract).

[0089] It should be noted that the structure of the second support member 72 is the same as that of the first support member 62, as shown in Figure 12.

[0090] Optionally, the second energy storage element 73 is a deformable spring. For example, the deformable spring is a spiral spring.

[0091] The principle of deformable springs is explained below with reference to Figure 13.

[0092] When a deformable spring is subjected to tension (the black arrow in Figure 13 indicates the direction of the tension) or torque on the axis (represented by the dashed arrow in Figure 13), the entire spring will generate deformation energy. When the tension or torque is removed, the original deformation energy will cause the deformable spring to return to its original state.

[0093] When the deformable spring is applied in this application, referring to Figure 6, when the first lens 2 and the second lens 3 move from their original positions (the state of the first winding mechanism 6 at this time is shown in Figures 7 and 9) in the second direction (that is, the two lenses move closer to each other and the lenses are in the retracted mode), as the lenses move, the protective layer 5 wound on the first winding mechanism 6 extends, that is, the first rotating shaft 61 distributed on the first edge 101 and the second edge 102 of the device housing 1 rotates in the direction of releasing the edge of the protective layer 5 (the state of the first winding mechanism 6 at this time is shown in Figures 8 and 10), driving the deformable spring provided on the first winding mechanism 6 to provide torque, and the deformable spring generates deformation energy; while the protective layer 5 wound on the second winding mechanism 7 further retracts, that is, the second rotating shaft 71 distributed on the second winding mechanism 7 of the first lens 2 and the second lens 3 rotates in the direction of rolling the edge of the protective layer 5, and the energy stored in the deformable spring of the second winding mechanism 7 provides power for the protective layer 5 from extension to contraction (retraction).

[0094] Referring to Figure 11, when the first lens 2 and the second lens 3 move from their original positions in the first direction (i.e., the two lenses move away from each other, and the lenses are in an outward expansion mode), the protective layer 5 wound on the second reel mechanism 7 extends as the lenses move. The second rotating shaft 71 distributed on the second reel mechanism 7 of the first lens 2 and the second lens 3 rotates in the direction of releasing the edge of the protective layer 5, driving the deformable spring set on the second reel mechanism 7 to provide torque, and the deformable spring generates deformation energy. Meanwhile, the protective layer 5 wound on the first reel mechanism 6 further retracts, that is, the first rotating shaft 61 distributed on the first reel mechanism 6 of the first reel mechanism 6 of the device housing 1 rotates in the direction of rolling the edge of the protective layer 5. The energy stored in the deformable spring of the first reel mechanism 6 provides the power for the protective layer 5 to retract from its extension.

[0095] In an optional embodiment, referring to FIG14, the motion adjustment mechanism 4 on the head-mounted display device includes a drive motor 41; wherein the drive motor 41 is connected to the lens (2,3) and the drive motor 41 is used to drive the lens (2,3) to move.

[0096] Furthermore, the moving adjustment mechanism 4 also includes: a first drive shaft 42 and a second drive shaft 43; wherein the first drive shaft 42 and the second drive shaft 43 are distributed on both sides of the lens (2,3) and are both parallel to the length direction of the device housing 1; the first drive shaft 42 is connected to the lens (2,3) and the second drive shaft 43 is connected to the lens (2,3); the drive motor 41 provides driving force to the lens (2,3) so that the lens (2,3) moves relative to the device housing (1) in the target direction through the first drive shaft 42 and the second drive shaft 43.

[0097] Here, the first drive shaft 42 and the second drive shaft 43 guide the movement of the lens (2,3), enabling the lens (2,3) to move toward the target direction.

[0098] The first drive shaft 42 and the second drive shaft 43 are both parallel to the length direction of the equipment housing 1, indicating that the first drive shaft 42 and the second drive shaft 43 are parallel. This ensures flatness and facilitates the smooth movement of the drive motor 41 on the lens (2,3).

[0099] Optionally, the first drive shaft 42 is connected to the lens (2,3) via a first plastic component, and the second drive shaft 43 is connected to the lens (2,3) via a second plastic component. Here, the plastic component not only serves as a connector but also helps to mute the movement of the lens (2,3), thus improving the user experience.

[0100] In the head-mounted display device of this application embodiment, when adjusting the distance between the lenses, the protective layer can be freely extended and contracted through the scaling structure, thereby reducing the resistance of the protective layer to the movement of the lenses and achieving the effect of not affecting the power consumption of the motor. Moreover, since the scaling structure can freely extend and contract the protective layer, it also allows for a wider range of material choices for the protective layer without affecting the function of the motor, resulting in better product performance.
