[0049] The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.

[0050] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0051] In the current state, the two lenses of the head-mounted display device can move inward or outward at the same time under the action of the driving motor. When the protective layer retracts inwards (that is, the two lenses move inwards at the same time), if the protective layer has weak elasticity, the protective layer on both sides of the temples of the head-mounted display device will be tightened; similarly, when the protective layer expands outwards (the two lenses move outwards at the same time), the protective layer on the center side of the head-mounted display device will be tightened; the above-mentioned tight state will cause the driving motor to provide additional power to the lens for the same distance of movement, resulting in increased motor power consumption and affecting the smoothness of the lens movement.

[0052] In order to solve the above technical problems, the present application embodiment provides a head display device. Figures 1 to 14 , the head display device provided in the embodiment of the present application is described in detail through specific embodiments and their application scenarios.

[0053] The embodiment of the present application provides a head display device, comprising a device housing 1 and lenses (2, 3) arranged in the device housing 1, a movable adjustment mechanism 4, the movable adjustment mechanism 4 is arranged in the device housing 1 and is respectively connected to the lenses (2, 3); the movable adjustment mechanism 4 is used to control the movement of the lenses (2, 3); a protective layer 5, the protective layer 5 is respectively connected to the lenses (2, 3) and the device housing 1; and a zoom structure 100 connected to the protective layer 5.

[0054] When the lens (2, 3) moves toward the target direction relative to the device housing 1, the zoom 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 zoom structure 100 during the movement, and the second part of the protective layer 5 is the part that is moved out of the zoom structure 100 during the movement.

[0055] Specifically, the lens (2, 3) includes a first lens 2 and a second lens 3. It should be understood that the movement of the lens (2, 3) relative to the device housing 1 toward the target direction may be that the first lens 2 moves relative to the device housing 1 toward the target direction, while the second lens 3 does not move; or the second lens 3 moves relative to the device housing 1 toward the target direction, while the first lens 2 does not move; or the first lens 2 and the second lens 3 move relative to the device housing 1 toward the target direction. The target direction may be a direction in which the first lens 2 and the second lens 3 approach each other, or a direction in which the first lens 2 and the second lens 3 move away from each other, or any direction.

[0056] In the head display device of the embodiment of the present application, when the distance between the lenses is adjusted, 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, thereby achieving the effect of not affecting the power consumption of the motor.

[0057] Optionally, the protective layer 5 is a flexible protective layer, that is, made of a flexible material.

[0058] In some embodiments, the zoom structure 100 includes: a first scroll mechanism 6 symmetrically arranged at a first edge 101 and a second edge 102 of the device housing 1, and the first scroll mechanism 6 is respectively connected to the protective layer 5 and the device housing 1, and the first edge 101 and the second edge 102 are both far away from the center of the device housing 1; a second scroll mechanism 7 symmetrically arranged at the first lens 2 and the second lens 3, and the second scroll mechanism 7 is respectively connected to the protective layer 5 and the lens (2, 3), one of the second scroll mechanisms 7 is arranged on a side of the first lens 2 away from the first edge 101, and the other second scroll mechanism 7 is arranged on a side of the second lens 3 away from the second edge 102.

[0059] 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 zoom structure 100 is not limited to four. This is just an example. The specific number may depend on the situation and is not specifically limited.

[0060] The first edge 101 and the second edge 102 are both far away from the center of the device housing 1. Figure 1 , it can be understood that the first edge 101 and the second edge 102 are respectively close to the temples of the head display device.

[0061] Specifically, when the target direction is the first direction, the first scroll mechanism 6 rotates toward the direction of rolling the edge of the protective layer 5 to shrink the first part of the protective layer 5, and the second scroll mechanism 7 rotates toward the direction of releasing the edge of the protective layer 5 to release the second part of the protective layer 5; or

[0062] 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 to release the second part of the protective layer 5; the second reel mechanism 7 rotates in the direction of rolling the edge of the protective layer 5 to shrink the first part of the protective layer 5, and the second direction is opposite to the first direction.

[0063] It should be understood that the edge of the protective layer 5 refers to the portion along the edge of the protective layer 5, and the reel mechanism (6, 7) is connected to this portion.

[0064] For example, the first direction is the direction in which the first lens 2 and the second lens 3 move away from each other, see Fig.11 The second direction is the direction in which the first lens 2 and the second lens 3 approach each other, see Figure 6 .Depend on Figure 6 and Fig.11 It can be seen that when the first lens 2 and the second lens 3 are directed toward the first direction under the control of the mobile 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 directed toward the second direction under the control of the mobile 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 near the head-mounted display device will be in a taut state; and by using the first scroll mechanism 6 and the second scroll mechanism 7 provided in the present application, when the first lens 2 and the second lens 3 are directed toward the first direction under the control of the mobile adjustment mechanism 4, the second scroll mechanism 7 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, thereby avoiding the protective layer 5 near the center of the device housing 1 from being in a taut state, and at the same time As the lens slowly approaches the first scroll mechanism 6, the first scroll mechanism 6 rotates in the direction of the edge of the rolling protective layer 5, so that the first part of the protective layer 5 shrinks, and the protective layer 5 between the lens and the first scroll mechanism 6 is stretched; and when the first lens 2 and the second lens 3 are moved in the second direction under the control of the moving adjustment mechanism 4, the first scroll 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, thereby preventing the protective layer 5 on both sides of the temples close to the head display device from being in a tight state. At the same time, the first lens 2 and the second lens 3 are slowly approaching, and the second scroll mechanism 7 rotates in the direction of the edge of the rolling protective layer 5, so that the first part of the protective layer 5 shrinks, and the protective layer 5 between the two lenses is stretched. In this way, the resistance of the protective layer to the movement of the lens can be reduced, thereby achieving the effect of not affecting the power consumption of the motor.

[0065] See also Figure 1 , Figure 6 and Fig.11 In an optional embodiment, the device housing 1 includes a first frame body 11 and a second frame body 12 snap-fittedly connected to the first frame body 11; wherein the lens (2, 3) and the movable adjustment mechanism 4 are arranged in the first frame body 11; and the protective layer 5 is respectively connected to the lens (2, 3) and the second frame body 12.

[0066] The first frame 11 and the second frame 12 are snap-fitted and connected, which facilitates the disassembly of the head display device and is beneficial to the subsequent replacement, maintenance or inspection of parts.

[0067] In some embodiments, see Figure 2 and Figure 3 , Figure 7 to Figure 10 The first reel mechanism 6 includes: a first rotating shaft 61, the first rotating shaft 61 is connected to the protective layer 5; a first energy storage component 60 is arranged at both ends of the first rotating shaft 61 and connects the first rotating shaft 61 and the device housing 1;

[0068] When the target direction is the first direction, the first rotating shaft 61 rotates toward the edge of the rolling protective layer 5 through the first energy storage assembly 60, so that the first part of the protective layer 5 shrinks;

[0069] When the target direction is the second direction, the first rotating shaft 61 rotates toward the direction of releasing the edge of the protective layer 5 through the first energy storage assembly 60, so that the second part of the protective layer 5 is released.

[0070] 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 respectively connected to the ends of the first rotating shaft 61 and the device housing 1.

[0071] Corresponding to the embodiment in which the above-mentioned device housing 1 includes a first frame body 11 and a second frame body 12, in this embodiment, the first support members 62 are arranged at both ends of the first rotating shaft 61 to connect the first rotating shaft 61 and the second frame body 12, and the first energy storage member 63 is arranged at both ends of the first rotating shaft 61 to connect the first rotating shaft 61 and the second frame body 12.

[0072] It should be noted that the first supporting member 62 is located between the first energy storage member 63 and the protective layer 5 .

[0073] When the first lens 2 and the second lens 3 are in the original position (which can be understood as the position of the first lens 2 and the second lens 3 when the head display device is just shipped from the factory), a portion of the edge of the protective layer 5 is wound around the first rotating shaft 61 (such as Figure 7 and Fig. 9This facilitates the first lens 2 and the second lens 3 to move toward the target direction when the excess protective layer can be extended to avoid the protective layer 5 being in a tight state.

[0074] 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 rolling protective layer 5. That is, the energy stored in the first energy storage component 63 provides power for the protective layer 5 to move from extension to contraction (retraction).

[0075] 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 the original position toward the second direction, and the first rotating shaft 61 rotates in the direction of releasing the edge of the protective layer 5, so that the first energy storage member 63 stores energy. Here, when the first lens 2 and the second lens 3 move from the original position toward the second direction, the first rotating shaft 61 rotates in the direction of releasing the edge of the protective layer 5, that is, the protective layer stretches, which can reduce the resistance of the protective layer to the movement of the lens, thereby achieving the effect of not affecting the power consumption of the motor.

[0076] For details, see Fig.12 The first support member 62 includes: a connection 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 connection portion 621, wherein the first support portion 622 connects the connection portion 621 and the device housing 1, and the second support portion 623 connects the connection portion 621 and the device housing 1. In this way, the first support member 62 with the above structural design can play a role in supporting the first rotating shaft 61.

[0077] Corresponding to the embodiment in which the device housing 1 includes a first frame body 11 and a second frame body 12 , the first supporting portion 622 connects the connecting portion 621 and the second frame body 12 , and the second supporting portion 623 connects the connecting portion 621 and the second frame body 12 .

[0078] Optionally, the first energy storage member 63 is a deformable spring. For example, the deformable spring is a spiral spring.

[0079] In some embodiments, see Figure 4 and Figure 5 The second reel mechanism 7 comprises: a second rotating shaft 71, the second rotating shaft 71 is connected to the protective layer 5; a second energy storage component 70 is arranged at both ends of the second rotating shaft 71 and connects the second rotating shaft 71 and the lens (2, 3);

[0080] When the target direction is the first direction, the second rotating shaft 71 rotates toward the direction of releasing the edge of the protective layer 5 through the second energy storage assembly 70, so that the second part of the protective layer 5 is released;

[0081] When the target direction is the second direction, the second rotating shaft 71 rotates toward the edge of the rolling protective layer 5 through the second energy storage assembly 70, so that the first part of the protective layer 5 shrinks.

[0082] 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 respectively connected to the end of the second rotating shaft 71 and the lens (2, 3).

[0083] It should be noted that the second supporting member 72 is located between the second energy storage member 73 and the protective layer 5 .

[0084] 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 display device is just shipped from the factory), a portion of the edge of the protective layer 5 is wrapped around the second rotating shaft 71; this allows the first lens 2 and the second lens 3 to move in the target direction so that there is excess protective layer extending out to avoid putting the protective layer 5 in a tight state.

[0085] 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, and the second rotating shaft 71 rotates toward the direction in which the edge of the protective layer 5 is released, so that the second energy storage member 73 stores 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 direction in which the edge of the protective layer 5 is released, that is, the protective layer is extended, so that the resistance of the protective layer to the movement of the lens can be reduced, thereby achieving the effect of not affecting the power consumption of the motor.

[0086] 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 the original position 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. That is, the energy stored in the second energy storage component 73 provides power for the protective layer 5 to move from extension to contraction (retraction).

[0087] It should be noted that the structure of the second support member 72 is the same as that of the first support member 62. Fig.12 .

[0088] Optionally, the second energy storage member 73 is a deformable spring. For example, the deformable spring is a spiral spring.

[0089] See below Fig.13 , explaining the principle of deformable spring.

[0090] The deformable spring is subjected to tension ( Fig.13The black arrow in the figure indicates the direction of the pulling force), or the torque on the axis (indicated by Fig.13 When the tension or torque is removed, the original deformation energy will cause the deformable spring to return to its original state.

[0091] When a deformable spring is used in this application, see Figure 6 The first lens 2 and the second lens 3 are in the original position (the state of the first reel mechanism 6 at this time is shown in FIG. Figure 7 and Fig. 9 When the two lenses move in the second direction (i.e., the two lenses are close to each other and the lenses are in the retracted mode), as the lenses move, the protective layer 5 wound on the first reel mechanism 6 is extended, that is, the first rotating shaft 61 of the first reel mechanism 6 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 reel mechanism 6 at this time is shown in FIG. Figure 8 and Fig.10 As shown in the figure), the deformable spring arranged on the first reel mechanism 6 provides torque, and the deformable spring generates deformation energy; and the protective layer 5 wound on the second reel mechanism 7 is further retracted, that is, the second rotating shaft 71 on the second reel mechanism 7 distributed on the first lens 2 and the second lens 3 rotates toward the direction of the edge of the rolling protective layer 5, and the energy stored in the deformable spring of the second reel mechanism 7 provides power for the protective layer 5 to move from extension to contraction (retraction).

[0092] See also Fig.11 , when the first lens 2 and the second lens 3 move from their original positions to the first direction (that is, the two lenses move away from each other and the lenses are in the outward expansion mode), as the lenses move, the protective layer 5 wound on the second reel mechanism 7 is extended, and the second rotating shaft 71 on the second reel mechanism 7 distributed on 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 provided on the second reel mechanism 7 to provide torque, and the deformable spring generates deformation energy. The protective layer 5 wound on the first reel mechanism 6 is further retracted, that is, the first rotating shaft 61 on the first reel mechanism 6 distributed on the first edge 101 and the second edge 102 of the device housing 1 rotates in the direction of rolling the edge of the protective layer 5, and the energy stored in the deformable spring of the first reel mechanism 6 provides power for the protective layer 5 to move from extension to contraction (retraction).

[0093] In an alternative embodiment, see Fig.14 The moving adjustment mechanism 4 on the head display device includes: a driving motor 41; wherein the driving motor 41 is connected to the lens (2, 3), and the driving motor 41 is used to drive the lens (2, 3) to move.

[0094] Furthermore, the moving adjustment mechanism 4 also includes: a first transmission shaft 42 and a second transmission shaft 43; wherein the first transmission shaft 42 and the second transmission 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 transmission shaft 42 is connected to the lens (2, 3), and the second transmission shaft 43 is connected to the lens (2, 3); the driving motor 41 provides driving force for the lens (2, 3), so that the lens (2, 3) moves toward the target direction relative to the device housing (1) through the first transmission shaft 42 and the second transmission shaft 43.

[0095] Here, the first transmission shaft 42 and the second transmission shaft 43 play a guiding role in the movement of the lens (2, 3), so that the lens (2, 3) can move towards the target direction.

[0096] Among them, the first transmission shaft 42 and the second transmission shaft 43 are both parallel to the length direction of the device housing 1, which means that the first transmission shaft 42 is parallel to the second transmission shaft 43. In this way, the flatness can be guaranteed, making it convenient for the driving motor 41 to smoothly move the lens (2, 3).

[0097] Optionally, the first transmission shaft 42 is connected to the lens (2, 3) via a first plastic part, and the second transmission shaft 43 is connected to the lens (2, 3) via a second plastic part. Here, the plastic part not only plays a connecting role, but also plays a silent role when the lens (2, 3) moves, thereby improving the user experience.

[0098] In the head display device of the embodiment of the present application, when the distance between the lenses is adjusted, the scaling structure can make the protective layer stretch and shrink freely, thereby reducing the resistance of the protective layer to the movement of the lenses, thereby achieving the effect of not affecting the power consumption of the motor. Moreover, since the scaling structure can make the protective layer stretch and shrink freely, the material selection of the protective layer is also wider, and it will not affect the function of the motor, thereby achieving a better product effect.
