Referring to fig. 1 to 13, an embodiment of the present invention provides a head-mounted display device, including a display part 1, a head-mounted assembly 2, and a position adjustment assembly 3; wherein, the display part 1 is connected with the position adjusting component 3; the position adjustment assembly 3 is mounted on the headgear assembly 2. The position adjustment assembly 3 is used to adjust the position of the display part 1 relative to the head-mounted assembly 2 to adjust the display part 1 to the first position or the second position.

When the head mounted display apparatus is worn by the user and the display part 1 is located at the first position with respect to the head mounted assembly 2, at least a part of the display part 1 is located directly in front of the eyes of the user. When the head mounted display apparatus is worn by the user and the display part 1 is located at the second position with respect to the head mounted assembly 2, the display part 1 is not located directly in front of the eyes of the user.

In this embodiment, the head-mounted display device has at least a display function, and the other functions included are not limited, and the placement positions of the components or parts that realize the corresponding functions are not limited, and can be flexibly set according to the actual application requirements. For example, in addition to the display function, the head-mounted display device may further include one or more functions of AR, VR, video playing, audio playing, image capturing, audio recording, voice communication, and the like, and the components for implementing the related functions may be disposed outside or inside the head-mounted assembly 2.

In this embodiment, the display unit 1 is used for displaying content for viewing by a user, and when the display unit 1 is located right in front of eyes of the user, the user can view the content displayed by the display unit 1. When the display part 1 is not positioned right in front of the eyes of the user, the display part 1 at least does not shield the view right in front of the eyes of the user, so that the user can conveniently view the view. The shape, structural composition and size of the display part 1 are not limited, for example, the display part 1 may be a waveguide type optical mechanical assembly, a free-form surface type optical mechanical assembly, or a prism type optical mechanical assembly.

In this embodiment, the head-mounted component 2 is used for supporting other components or parts of the head-mounted display device, and is worn by the head of the user, and the specific shape and structural composition are not limited, and can be flexibly set according to actual application requirements. For example, the head mount assembly 2 may be in the form of glasses, a hat, or the like.

In order to ensure the safety, the aesthetic property and the stability of the head-mounted display device, the head-mounted assembly 2 at least comprises a housing having a receiving cavity, electronic components such as a controller (not shown), a main board (not shown), a connecting line (not shown), a power supply (not shown) and the like can be installed in the receiving cavity, and the display component 1 is electrically connected with at least the controller in the receiving cavity.

In this embodiment, the position adjustment assembly 3 is used to adjust the position of the display component 1 relative to the head wearing assembly 2, and the specific structure and the adjustment mode are not limited, and can be flexibly set according to the actual application requirements. For example, position adjustment assembly 3 may adjust the position of display member 1 relative to head mounted assembly 2 by moving display member 1 and/or adjust the position of display member 1 relative to head mounted assembly 2 by rotating display member 1.

In this embodiment, the first position and the second position may refer to only two fixed positions, or may be a general term for a plurality of positions. For a user with the pupil distance and the head width within the normal range, when the head-worn assembly 2 is worn behind the head in a correct manner and the display unit 1 is located at the first position relative to the head-worn assembly 2, at least part of the display unit 1 is located directly in front of the eyes of the user, that is, at least part of the display unit 1 is located in the field of view directly in front of the user, thereby facilitating the user to view the content displayed by the display unit 1. If the user does not need to view the content displayed by the display part 1, referring to fig. 3 and 4, the display part 1 can be adjusted to the second position relative to the head-mounted assembly 2 to move the display part 1 away from the front of the eyes of the user, that is, the display part 1 is located outside the visual field area in front of the eyes of the user, so that the shielding of the display part 1 on the visual field of the user can be avoided, and if the user does not need to view the content displayed by the display part 1 in the using process, the user does not need to move the head-mounted display device out of the head, which is beneficial to improving the using experience of the user.

Wherein, referring to fig. 1-2, and 5-8, display member 1 may also have different angles of rotation relative to head-mounted assembly 2 when display member 1 is in the first position relative to head-mounted assembly 2. Likewise, display member 1 may have a different angle of rotation relative to head mounted assembly 2 when display member 1 is in the second position relative to head mounted assembly 2. Different users can adjust the position of the display part 1 according to the self pupil distance, head width and use habits so as to obtain better wearing experience.

Alternatively, in order to adjust the position of the display part 1 more conveniently, the position adjustment assembly 3 may include a first sliding part 31 and a second sliding part 32 that are slidably coupled. The first slider 31 is attached to the head mount assembly 2, and the display unit 1 is connected to the second slider 32. When the position of the display part 1 relative to the head-mounted assembly 2 needs to be adjusted, the second sliding part 32 can drive the display part 1 to move relative to the first sliding part 31 and the head-mounted assembly 2, so as to adjust the display part 1 to the first position or the second position. The specific structure, shape, material and the like of the first sliding portion 31 and the second sliding portion 32 are not limited, and can be reasonably selected according to the actual application requirements. For example, one of the first sliding portion 31 and the second sliding portion 32 may be a sliding rail, and the other one is a sliding block, and the sliding rail is movably connected with the sliding block; one of the first sliding portion 31 and the second sliding portion 32 may be a sliding groove, and the other may be a slider, and the slider is mounted in the sliding groove.

Further, considering that the weight of the head-worn assembly 2 is generally heavier than that of the display part 1, in order to ensure the overall structural strength, referring to fig. 9-13, it is preferable that the first sliding part 31 is a sliding rail, and the second sliding part 32 is a sliding block, so that when the sliding block moves along the sliding rail, the position of the display part 1 relative to the position adjustment assembly 3 can be adjusted. The slide rail can be integrally formed on the shell of the head wearing component 2, and can also be mounted on the shell of the head wearing component 2 through fasteners, gluing, welding and the like, and the connection mode of the slide rail and the head wearing component 2 is not limited in the embodiment.

Further, considering that different users may have different requirements for the placement angle of the display part 1 relative to the eyes when viewing the content displayed on the display part 1, in order to better meet the requirements of the users, referring to fig. 9, the position adjustment assembly 3 may further include a rotating part 33 mounted on the second sliding part 32, the rotating part 33 is connected to the display part 1, and the rotating part 33 is used for driving the display part 1 to rotate relative to the head wearing assembly 2. The user can not only move the display part 1 relative to the head-mounted assembly 2 by using the position adjusting assembly 3, but also rotate the display part 1 relative to the head-mounted assembly 2, that is, the rotating part 33 can drive the display part 1 to rotate relative to the head-mounted assembly 2, so that when the display part 1 is located at the first position or the second position relative to the head-mounted assembly 2, the display part can also have different rotation angles relative to the head-mounted assembly 2.

The shape, size and structural composition of the rotating part 33 are not limited, and can be reasonably selected according to the actual application requirements. For example, the turning portion 33 may include one or more turning shaft structures such that the display member 1 can be rotated with respect to the turning shaft structures; the rotation part 33 may further include a rotation sphere structure so that the display part 1 can be rotated in a plurality of different directions by the rotation sphere structure.

Further, referring to fig. 10 and 11, the rotating portion 33 includes a first rotating member 331 and a second rotating member 332, the first rotating member 331 is mounted on the second sliding portion 32, the first rotating member 331 is rotatably connected with the second rotating member 332, and the second rotating member 332 is rotatably connected with the display part 1. The axis of the first rotating member 331 is not parallel to the axis of the second rotating member 332, so that the display part 1 can be rotated by the first rotating member 331 and the second rotating member 332 along the axes of a plurality of different directions, and the range of positional adjustment of the display part 1 with respect to the head mounted assembly 2 is expanded.

The connection mode between the first rotating member 331 and the second sliding portion 32, the connection mode between the second rotating member 332 and the first rotating member 331, and the connection mode between the second rotating member 332 and the display unit 1 are not limited, and can be selected reasonably according to actual application requirements. For example, the connection may be direct or indirect.

Further, in order to ensure the stability of the overall structure and further expand the position adjustment range of the display part 1 relative to the head-mounted assembly 2, it is preferable that the first rotating member 331 and the second rotating member 332 are both rotating shafts, and the axis of the first rotating member 331 is perpendicular to the axis of the second rotating member 332.

Further, in order to facilitate the manufacturing process and assembly, referring to fig. 10 and 11, the rotating part 33 may include a first rotating member 331, a second rotating member 332, a first rotating fixing member 333, and a second rotating fixing member 334, wherein the first rotating member 331 is integrally formed with the second sliding part 32, or the first rotating member 331 is fixedly mounted on the second sliding part 32; the second rotating part 332 is rotatably connected with the first rotating part 331 through a first rotating fixing part 333, wherein the second rotating part 332 is integrally formed with the first rotating fixing part 333, or the second rotating part 332 is fixedly mounted on the first rotating fixing part 333; the second rotating fixing member 334 is fixedly connected to the display unit 1, and the second rotating fixing member 334 is rotatably connected to the second rotating member 332.

During use, a user can drive the display component 1 to rotate around the axis of the second rotating component 332 relative to the second rotating component 332 through the second rotating fixing component 334; the first rotating fixing part 333 drives the second rotating part 332, the second rotating fixing part 334 and the display part 1 to rotate around the axis of the first rotating part 331 relative to the first rotating part 331 and the second sliding part 32, so as to adjust the rotation angle of the display part 1 relative to the head wearing assembly 2 and the second sliding part 32.

For example, referring to fig. 11, if the axis of the first rotating member 331 is parallel to the z direction in the drawing, and the axis of the second rotating member 332 is parallel to the x direction in the drawing, when the display part 1 is located at the first position relative to the head-mounted component 2, the first rotating fixing member 333 can drive the second rotating member 332, the second rotating fixing member 334 and the display part 1 to rotate around the axis parallel to the z direction relative to the first rotating member 331 and the second sliding part 32, so that the display part 1 can be adjusted from the first rotation angle of the first position shown in fig. 1 and 2 to the second rotation angle of the first position shown in fig. 5 or from the first rotation angle of the first position shown in fig. 1 and 2 to the third rotation angle of the first position shown in fig. 6 relative to the head-mounted component 2.

When the display part 1 is located at the first position relative to the head-mounted assembly 2, the second rotating fastener 334 can drive the display part 1 to rotate relative to the second rotating member 332 around an axis parallel to the x-direction, so that the display part 1 can be adjusted to a fourth rotation angle from the first rotation angle of the first position shown in fig. 1 and 2 to the first position shown in fig. 7, or to a fifth rotation angle from the first position shown in fig. 1 and 2 to the second rotation angle shown in fig. 8, relative to the head-mounted assembly 2.

Alternatively, in order to limit the movement range of the second sliding portion 32 relative to the first sliding portion 31, that is, to limit the movement range of the display component 1 relative to the head-mounted component 2, referring to fig. 12 and 13, the position adjusting component 3 may further include a first limiting member 35 and a second limiting member 36, and the first limiting member 35 and the second limiting member 36 are respectively disposed at two ends of the first sliding portion 31. When the display component 1 is located at the first position relative to the head-mounted assembly 2, the first limiting member 35 abuts against the second sliding portion 32 to prevent the second sliding portion 32 from continuously sliding relative to the first sliding portion 31 in the direction of the first limiting member 35. When the display component 1 is located at the second position relative to the head-mounted assembly 2, the second limiting member 36 abuts against the second sliding portion 32 to prevent the second sliding portion 32 from continuously sliding relative to the first sliding portion 31 in the direction of the second limiting member 36. The number, shape, size, etc. of the first limiting member 35 and the second limiting member 36 are not limited, and can be reasonably selected according to the actual application requirements.

For example, referring to fig. 12 and 13, the first stopper 35 and the second stopper 36 may be provided in different shapes and respectively provided at both ends of the first sliding portion 31; the number of the first limiting members 35 and the number of the second limiting members 36 are two, and both are symmetrically arranged relative to the first sliding portion 31.

Further, in order to improve the connection stability of the display part 1 in the first position and the second position with respect to the head mount assembly 2 and to provide a better operation experience for the user during the operation of adjusting the position of the display part 1, referring to fig. 12 and 13, the position adjusting assembly 3 may further include a profile spring 34, a first end of the profile spring 34 being rotatably connected to the first sliding portion 31, and a second end of the profile spring 34 being rotatably connected to the second sliding portion 32. The specific shape and size of the special-shaped spring 34 are not limited, and can be reasonably selected according to the actual application requirements.

When the second sliding portion 32 slides relative to the first sliding portion 31, the first end of the shaped spring 34 is driven to rotate relative to the first sliding portion 31, and the second end of the shaped spring 34 is driven to rotate relative to the second sliding portion 32, and a portion between the first end and the second end of the shaped spring 34 is elastically deformed, so that the elastic force generated by the elastic deformation can drive the second sliding portion 32 to slide relative to the first sliding portion 31, and further the second sliding portion 32 abuts against the first limiting member 35 or the second limiting member 36. So that the user can reduce the magnitude and length of the urging force in the process of operating the second slider portion 32 to slide relative to the first slider portion 31.

Specifically, since the wire spring 34 has a critical point of deformation, elastic forces having different directions are generated at both sides of the critical point. When the user operates the second sliding portion 32 to slide in one direction relative to the first sliding portion 31, after the wire spring 34 exceeds the critical point of deformation, even if the user does not continuously apply force between the first sliding portion 31 and the second sliding portion 32, the wire spring 34 can drive the second sliding portion 32 to continuously slide in the one direction relative to the first sliding portion 31; if the user does not continue to apply force between the first sliding portion 31 and the second sliding portion 32 when the wire spring 34 does not exceed the critical point of deformation, the wire spring 34 will drive the second sliding portion 32 to slide in the direction opposite to the direction relative to the first sliding portion 31.

Alternatively, in order to facilitate assembly of the display part 1 and improve the overall aesthetic appearance of the head-mounted display device, referring to fig. 1 to 8, the head-mounted assembly 2 may include a wearing front portion 21 and a wearing side portion 22, the wearing front portion 21 being located in front of the head of the user when the head-mounted display device is worn by the user, the wearing side portion 22 being located at the side of the head of the user, the first sliding portion 31 being installed at a connection position of the wearing front portion 21 and the wearing side portion 22, and the shape of the first sliding portion 31 being adapted to the shape at the connection position of the wearing front portion 21 and the wearing side portion 22. When the head-mounted component 2 is in the form of eyeglasses, the front-mounted part 21 refers to a frame of the eyeglasses, and the side-mounted part 22 refers to at least one temple of the eyeglasses.

Alternatively, in order to improve the overall aesthetic appearance of the head-mounted display device and to make the second sliding portion 32 slide relatively smoothly relative to the second sliding portion 32, referring to fig. 1 to 8, the connection position of the wearing front portion 21 and the wearing side portion 22 may include an arc-shaped transition surface, the first sliding portion 31 is fitted or embedded on the arc-shaped transition surface, and the shape of the first sliding portion 31 is adapted to the arc-shaped transition surface.

When the first sliding part 31 is a slide rail and the second sliding part 32 is a slide block, the shape of the slide rail is matched with the arc transition surface.

Further, referring to fig. 9, the display component 1 may include an optical engine rear housing 11, a switching circuit board 12, an optical engine body 13 and an optical engine front housing 14, wherein the switching circuit board 12 and the optical engine body 13 are located in a containing cavity formed by buckling and connecting the optical engine front housing 14 and the optical engine front housing 14, so as to facilitate assembly, avoid the switching circuit board 12 from being exposed, and facilitate improvement of the overall aesthetic property of the product.

Further, for the convenience of assembly, it is also preferable that the optical machine rear case 11 is engaged with the second rotating fixture 334.

Further, in order to reduce the power consumption of the head-mounted display device during use, when the display part 1 is located at a first position relative to the head-mounted assembly 2, for example, when the user wears the head-mounted display device and then the display part 1 is located in a visual field area right in front of the eyes of the user, the control assembly controls the display part 1 to be in an operating state; when the display part 1 is located at a second position relative to the head-mounted assembly 2, for example, when the user wears the head-mounted display device so that the display part 1 is located outside the visual field area right in front of the eyes of the user, the control assembly controls the display part 1 to be in a non-working state.

The working state of the display part 1 means that the display part 1 can display contents for a user to view after being powered on, for example, a display screen in the display part 1 is lightened; the non-operating state of the display part 1 means that the display part 1 is not powered on, or the display part does not display the content for the user to view after being powered on, for example, the display screen in the display part 1 is not lighted up and is in a black screen state.

Further, in order to automatically control the display component 1 to switch between the working state and the non-working state, the control assembly may include a hall switch (not shown), a magnetic body (not shown), and a controller, the controller being electrically connected to the hall switch; the Hall switch is arranged on the head wearing component 2; the magnetic body is mounted on the second slide portion 32.

When the second sliding part 32 drives the display part 1 to slide to a first position relative to the head wearing assembly 2, the hall switch generates and sends a first control signal to the controller, so that the controller controls the display part 1 to be in a working state; when the second sliding portion 32 drives the display component 1 to slide to the second position relative to the head-wearing component 2, the hall switch generates and sends a second control signal to the controller, so that the controller controls the display component 1 to be in a non-working state.

When the magnetic body is close to the Hall switch, the magnetic field intensity of the Hall switch is increased, and the Hall switch can be triggered to send a signal to the controller; when the magnetic body is far away from the Hall switch, the magnetic field intensity of the Hall switch is weakened, and the Hall switch can be triggered to send a signal to the controller.

In addition, the Hall switch has the characteristics of no contact, low power consumption, long service life, high response frequency and the like, and can reliably work in various severe environments, so that the use reliability and the service life of the head-mounted display equipment can be improved by adopting the Hall switch.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
