Referring to fig. 1 to 13, an embodiment of the present utility model provides a head-mounted display apparatus 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 assembly 3; the head wear assembly 2 includes a wear front 21 and a wear side 22, and the position adjustment assembly 3 is mounted at a connection position of the wear front 21 and the wear side 22. The position adjustment assembly 3 is used to adjust the position of the display member 1 relative to the head-worn assembly 2 to adjust the display member 1 to either the first position or the second position.

When the user wears the head mounted display device and the display part 1 is in the first position relative to the head mounted assembly 2, at least part of the display part 1 is located directly in front of the eyes of the user. When the user wears the head mounted display device and the display part 1 is in the second position relative 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 other functions included are not limited, and the placement positions of components or parts for implementing the corresponding functions are not limited, so that the head-mounted display device can be flexibly set according to 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, etc., and components for implementing the relevant 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 positioned directly 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 eyes of the user, the display part 1 at least does not shade the view right in front of eyes of the user, so that the user can conveniently view the view. The shape, the structural composition and the size of the display component 1 are not limited, and for example, the display component 1 may be a waveguide-type optical-mechanical assembly, a free-form-surface optical-mechanical assembly, or a prism-type optical-mechanical assembly.

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

In order to ensure the safety, the aesthetic appearance and the stability of the head-mounted display device, the head-mounted assembly 2 includes at least a housing having a receiving cavity, in which electronic components such as a controller (not shown), a main board (not shown), a connection line (not shown), a power source (not shown) and the like are mounted, and the display part 1 is electrically connected to at least the controller in the receiving cavity.

In this embodiment, referring to fig. 1-8, the head wear assembly 2 includes a wear front 21 and a wear side 22, the wear front 21 being positioned in front of the head of the user and the wear side 22 being positioned laterally of the head of the user when the head mounted display device is worn by the user.

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

In this embodiment, the first position and the second position may refer to only two fixed positions, or may be a generic term for a plurality of positions. For a user whose interpupillary distance and head width are within normal ranges, when the head-mounted assembly 2 is worn behind the head in a correct manner and the display member 1 is located at the first position relative to the head-mounted assembly 2, at least part of the display member 1 is located directly in front of the eyes of the user, i.e., at least part of the display member 1 is located in a field of view directly in front of the user, so that the user can conveniently view what is displayed by the display member 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 wearing assembly 2, so that the display part 1 is moved away from the front of the eyes of the user, that is, the display part 1 is positioned outside the visual field area in the front of the eyes of the user, thereby avoiding the shielding of the display part 1 to the visual field of the user, and the user does not need to move the head wearing display device out of the head if the user does not need to view the content displayed by the display part 1 in the use process, which is beneficial to improving the use experience of the user.

With reference to fig. 1-2, and fig. 5-8, the display member 1 may also have a different angle of rotation relative to the head-worn assembly 2 when the display member 1 is in the first position relative to the head-worn assembly 2. Likewise, when the display member 1 is in the second position relative to the head-mounted assembly 2, the display member 1 may also have a different angle of rotation relative to the head-mounted assembly 2. Different users can adjust the position of the display part 1 according to the pupil distance, the head width and the use habit of the users, 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 portion 31 and a second sliding portion 32 slidably connected. The first sliding portion 31 is mounted on the head-mounted assembly 2, and the display member 1 is connected to the second sliding portion 32. When the position of the display part 1 relative to the head-wearing 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-wearing assembly 2 so as to adjust the display part 1 to the first position or the second position. The specific structure, shape, material, etc. of the first sliding portion 31 and the second sliding portion 32 are not limited, and may be reasonably selected according to practical 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 may be a sliding block, where 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 slide groove, and the other may be a slider, and the slider is mounted in the slide groove.

Further, considering that the head wear assembly 2 will generally be heavier than the display member 1, in order to ensure the overall structural strength, referring to fig. 9-13, it may be preferable that the first sliding portion 31 is a slide rail and the second sliding portion 32 is a slider, and the position of the display member 1 relative to the position adjustment assembly 3 may be adjusted when the slider moves along the slide rail. The sliding rail can be integrally formed on the shell of the head wearing assembly 2, and can be mounted on the shell of the head wearing assembly 2 through fastening pieces, gluing, welding and other modes, and the connection mode of the sliding rail and the head wearing assembly 2 is not limited in this embodiment.

Further, considering that different users may have different requirements on the placement angle of the display part 1 relative to the eyes when viewing the content displayed by the display part 1, in order to better meet the user requirements, referring to fig. 9, the position adjustment assembly 3 may further include a rotating portion 33 mounted on the second sliding portion 32, where the rotating portion 33 is connected to the display part 1, and the rotating portion 33 is used to drive 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-wearing assembly 2 by using the position adjustment assembly 3, but also rotate the display part 1 relative to the head-wearing assembly 2, i.e. the rotating part 33 can drive the display part 1 to rotate relative to the head-wearing assembly 2, so that when the display part 1 is located at the first position or the second position relative to the head-wearing assembly 2, the display part can also have different rotation angles relative to the head-wearing assembly 2.

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

Further, referring to fig. 10 and 11, the rotating part 33 includes a first rotating member 331 and a second rotating member 332, the first rotating member 331 is mounted on the second sliding part 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 rotate along a plurality of axes of different directions by the first rotating member 331 and the second rotating member 332, and the position adjustment range of the display part 1 relative to the head wearing assembly 2 is enlarged.

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 member 1 are not limited, and may be reasonably selected according to practical application requirements. For example, the connection may be direct or indirect.

Further, in order to secure the stability of the overall structure while further expanding the adjustment range of the position of the display part 1 with respect to the head-wearing assembly 2, it is preferable that both the first rotating member 331 and the second rotating member 332 are rotation shafts, and the axis of the first rotating member 331 is perpendicular to the axis of the second rotating member 332.

Further, for the convenience of production processing 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 member 332 is rotatably connected with the first rotating member 331 through the first rotating fixing member 333, wherein the second rotating member 332 is integrally formed with the first rotating fixing member 333, or the second rotating member 332 is fixedly mounted on the first rotating fixing member 333; the second rotation fixing piece 334 is fixedly connected with the display part 1, and the second rotation fixing piece 334 is rotatably connected with the second rotation piece 332.

In use, a user can rotate the display part 1 relative to the second rotating member 332 around the axis of the second rotating member 332 through the second rotating fixing member 334; the second rotating member 332, the second rotating member 334, and the display member 1 are rotated about the axis of the first rotating member 331 with respect to the first rotating member 331 and the second sliding portion 32 by the first rotating member 333, thereby adjusting the rotation angle of the display member 1 with respect to the head wearing assembly 2 and the second sliding portion 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, 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 with respect to the head wearing assembly 2, the second rotating member 332, the second rotating member 334, and the display part 1 may be rotated about the axis parallel to the z direction with respect to the first rotating member 331 and the second sliding portion 32 by the first rotating member 333, so that the display part 1 may 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 with respect to the head wearing assembly 2, 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.

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

Alternatively, in order to limit the movement range of the second sliding portion 32 with respect to the first sliding portion 31, that is, limit the movement range of the display member 1 with respect to the head-wearing assembly 2, referring to fig. 12 and 13, the position adjustment assembly 3 may further include a first stopper 35 and a second stopper 36, the first stopper 35 and the second stopper 36 being disposed at both ends with the first sliding portion 31, respectively. When the display member 1 is located at the first position relative to the head-wearing assembly 2, the first stopper 35 abuts against the second sliding portion 32, so as to prevent the second sliding portion 32 from sliding further relative to the first sliding portion 31 in the direction in which the first stopper 35 is located. When the display member 1 is located at the second position relative to the head-wearing assembly 2, the second stopper 36 abuts against the second sliding portion 32, so as to prevent the second sliding portion 32 from sliding further relative to the first sliding portion 31 in the direction in which the second stopper 36 is located. 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 practical application requirements.

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

Further, in order to enhance the connection stability of the display part 1 in the first position and the second position with respect to the head-wearing assembly 2 and to enable a user to obtain a better operation experience during the operation of adjusting the position of the display part 1, referring to fig. 12 and 13, the position adjustment assembly 3 may further include a shaped spring 34, wherein a first end of the shaped spring 34 is rotatably connected to the first sliding portion 31, and a second end of the shaped spring 34 is rotatably connected to the second sliding portion 32. The specific shape and size of the shaped spring 34 are not limited, and may be reasonably selected according to practical application requirements.

When the second sliding portion 32 slides relative to the first sliding portion 31, the first end of the shaped spring 34 can be driven to rotate relative to the first sliding portion 31, and the second end of the shaped spring 34 can be 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 can be elastically deformed, and 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 enable the second sliding portion 32 to abut against the first limiting member 35 or the second limiting member 36. So that the user can reduce the magnitude and duration of the urging force in the process of operating the second sliding portion 32 to slide with respect to the first sliding portion 31.

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

Alternatively, in order to facilitate assembly of the display part 1 and to improve the overall aesthetic appearance of the product of the head-mounted display device, the first sliding portion 31 is installed at the connection position of the wearing front portion 21 and the wearing side portion 22, and the shape of the first sliding portion 31 is adapted to the shape at the connection position of the wearing front portion 21 and the wearing side portion 22. When the head wearing unit 2 is in the form of eyeglasses, the wearing front portion 21 means a frame of the eyeglasses, and the wearing side portion 22 means at least one temple of the eyeglasses.

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

When the first sliding portion 31 is a sliding rail and the second sliding portion 32 is a sliding block, the shape of the sliding rail is adapted to the arc-shaped transition surface.

Optionally, the head mounted display device further comprises a control assembly (not shown) mounted on the head mounted assembly 2 and a power supply, both of which are electrically connected to the display part 1. The specific type of the power supply is not limited, and the power supply can be reasonably selected according to actual application requirements. For example, the power source may be a primary battery or a secondary battery mounted on the head-mounted module 2, or may be an external power source externally connected via a connection line.

Further, referring to fig. 9, 12 and 13, the display component 1 may include a relay circuit board 12 and an optomechanical body 13, the relay circuit board 12 being used to electrically connect the optomechanical body 13 and a control assembly located on the head-mounted assembly 2. When the light machine body 13 is electrified, the light machine body 13 can display content for a user to check. The first sliding portion 31 is provided with a wiring hole 311, and the switching circuit board 12 passes through the wiring hole 311 to connect the control assembly and the display component 1. Referring to fig. 1-8, this facilitates the electrical connection of the control assembly to the opto-engine body 13 and improves the safety of the product in use.

Further, referring to fig. 9, the display component 1 may include a rear chassis 11, a switching circuit board 12, a front chassis 13 and a front chassis 14, where the switching circuit board 12 and the front chassis 13 are located in a receiving cavity formed by snap-fit connection of the front chassis 14 and the front chassis 14, so that not only is assembly convenient, but also the switching circuit board 12 is prevented from being exposed, which is beneficial to improving the overall aesthetic property of the product.

Further, for ease of assembly, it is also preferable that the rear housing 11 of the optical engine is engaged with the second rotation fixing member 334.

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

The working state of the display component 1 means that the display component 1 can display content for a user to view after being electrified, for example, a display screen in the display component 1 is lightened; the inactive state of the display unit 1 means that the display unit 1 is not energized or does not display content for the user to view after being energized, for example, the display screen in the display unit 1 is not turned on and is in a black screen state.

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

When the second sliding part 32 drives the display part 1 to slide to the 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 assembly 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 strength of the Hall switch is increased, and the Hall switch can be triggered to send signals to the controller; when the magnetic body is far away from the Hall switch, the intensity of the magnetic field where the Hall switch is positioned is weakened, and the Hall switch can be triggered to send signals to the controller.

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

Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present utility model, and not for limiting the same; although the utility model has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some or all of the technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit of the utility model.
