AR devices, VR devices, etc. are one type of portable intelligent head mounted display device. The head-mounted display device is provided with an imaging device and a projection device, and the optical machine projects an image to a grating area on the waveguide lens, so that a user can see a picture that the projected virtual image is superimposed on a physical environment. The head-mounted display device is often configured into a binocular structure, namely, two imaging devices and a projection device are arranged in the AR device, and due to poor binocular vision, after the left eye and the right eye of a user see two object images to be transferred to the brain, a complete single object image with 3D stereoscopic vision is generated through analysis and synthesis. Similarly, in order to secure the imaging position, the head-mounted display apparatus is also extremely high in the requirement of the degree of positional variation of each imaging device and projection device.
However, the daily use environment of the user is complex, and due to the head circumference difference of different users, the glasses legs can be turned outwards to deform the glasses frame, so that the positions of the imaging device and/or the projection device are changed, violent tearing or accidental falling and other conditions can occur, the positions of the imaging device and/or the projection device are changed, the imaging effect of the head-mounted display device is affected, and the use experience of the user is affected.
The present invention proposes a head mounted display device 10, which head mounted display device 10 may be an AR device or a VR device or the like.
In the embodiment of the present invention, as shown in fig. 1 to 10, the head-mounted display device 10 includes a temple 12, a frame 11, and an optical machine module 13, the temple 12 being mounted at an end of the frame 11; the optical module 13 is disposed in the lens frame 11, the middle portion 131a of the optical module 13 is fixed to the lens frame 11, and the rest of the optical module 13 is disposed in a gap with the lens frame 11.
Specifically, the middle portion 131a of the optical module 13 is fixed in the frame 11 for imaging the head-mounted display device 10. The temple 12 is mounted on an end portion of the frame 11, and in general, the temple 12 is rotatably mounted on the frame 11 such that the temple 12 can rotate relative to the frame 11, thereby enabling the head-mounted display device 10 to be opened and retracted. Therefore, bending deformation tends not to occur when the temple 12 moves inward (toward the side of the face), but bending deformation tends to occur when the temple 12 moves outward (away from the face). When the glasses legs 12 are bent, a larger torque is generated on two sides of the glasses frame 11, the torque can force the glasses frame 11 to deform, and the glasses frame 11 can drive the optical machine module 13 inside the glasses frame to deform, so that the imaging effect is affected. The deformation of the end portion of the frame 11 is often larger and gradually decreases toward the middle portion 131a of the frame 11, so that the middle portion 131a of the frame 13 is fixed to the frame 11 and the rest of the frame 13 is disposed in a gap with the frame 11 to reduce the possibility of deformation of the frame 11 and the deformation of the frame 13. That is, only the middle part 131a of the optical machine module 13 is hung in the lens frame 11, the middle part 131a of the optical machine module 13 is the middle part 131a of the lens frame 11, that is, the optical machine module 13 is hung at the position with the minimum deformation in the lens frame 11, so that the possibility of shifting the optical machine module 13 in the lens frame 11 in the use process is reduced, and the wearing comfort of a user is improved.
The middle portion 131a of the optical module 13 is the middle portion 131a of the frame 11, and corresponds to the nose bridge of the wearer. The rest of the optical module 13 is disposed in a gap with the lens frame 11, that is, the optical module 13 and the housing of the lens frame 11 have no connection relationship except for the mounting portion of the optical module 13 and the lens frame 11. For easy assembly, the lens frame 11 includes a front housing 113 and a rear housing 114 that are spliced with each other, and the optical module 13 may be mounted on the front housing 113 or on the rear housing 114, or the optical module 13 may be mounted on the front housing 113 and the rear housing 114 at the same time, that is, the optical module 13 is sandwiched between the front housing 113 and the rear housing 114. And the rest positions of the optical machine module 13 except the installation part of the optical machine module 11 are provided with a certain gap with the optical machine module 11, so that the deformation of the optical machine module 13 caused by the deformation of the glasses legs 12 can be blocked, the possibility that the internal electronic device of the optical machine module 13 is shifted by the front shell 113 or the rear shell 114 of the optical machine module 13 after the deformation of the optical machine module 11 when the optical machine module 11 is impacted (the head-mounted display device 10 is accidentally dropped) can be reduced, the possibility that the optical machine module 13 in the optical machine module 11 is shifted in the use process is further reduced, and the wearing comfort of a user is improved.
In the present embodiment, the temple 12 is rotatably connected to an end of the rear housing 114, and the middle portion 131a of the opto-mechanical module 13 is fixed to the rear housing 114. That is, the rear shell 114 is used for being connected with the temple 12, and the front shell 113 is spliced with the rear shell 114 and then connected with the temple 12, so that the end of the front shell 113 does not generate connection relation with the temple 12, and further the possibility that the front shell 113 drives the optical machine module 13 to deform due to the outward turning of the temple 12 is reduced. Also, since the end portion of the front housing 113 does not have a connection relationship with the temple 12, when the temple 12 is bent outward, the front housing 113 may be separated from the rear housing 114, so that the middle portion 131a of the optical module 13 is fixed to the rear housing 114, which not only ensures the mounting stability of the optical module 13, but also reduces the possibility of deformation of the optical module 13. Of course, in other embodiments, the middle portion 131a of the optical module 13 may be fixed to the front housing 113, or the temple 12 is rotatably connected to an end portion of the front housing 113; or the temples 12 are simultaneously rotatably connected to the ends of the front case 113 and the rear case 114.
In this embodiment, the middle portion 131a of the optical module 13 is fixed on the frame 11 through the fastener 16, so that the installation stability of the optical module 13 can be ensured, the assembly of the optical module 13 can be facilitated, and the assembly space of the optical module 13 can be reduced to a certain extent compared with the case that the optical module 13 is fastened and fixed on the frame 11. The fastening members 16 may be configured as fastening screws, and at least two fastening members 16 are provided for securing the mounting stability of the opto-mechanical module 13. In other embodiments, the middle portion 131a of the optical module 13 may be fastened to the frame 11 by a clamping or bonding.
Further, to facilitate the installation and positioning of the opto-mechanical module 13, in one embodiment, the frame 11 is provided with positioning posts 17 for positioning the opto-mechanical module 13. The positioning column 17 can be used for positioning the optical machine module 13, for example, a positioning hole is correspondingly formed in the optical machine module 13, and when the optical machine module 13 is installed, the positioning column 17 is inserted into the positioning hole, so that the installation of the fastener 16 is facilitated.

Specifically, the optical machine bracket 131 is used for fixing the lens 133 and the optical machine 132, so the optical machine bracket 131 extends along the extending direction of the lens frame 11, the middle portion 131a of the optical machine bracket 131 is the middle portion 131a of the lens frame 11, the two rib portions 131b are used for correspondingly mounting the two lenses 133 and the two optical machines 132, the lenses 133 are configured as waveguide lenses, and the two rib portions 131b are configured as reinforcing structures, thereby ensuring the mounting reliability of the optical machines 132 and the lenses 133. One optical machine 132 and one lens 133 together form a group of imaging components, so that the two optical machines 132 and the two lenses 133 are arranged in a one-to-one correspondence, the optical machine 132 is positioned at the rear side of the lens 133, and a waveguide area is arranged on the lens 133, thereby realizing imaging of the head-mounted display device 10.
To further reduce the possibility that the rear housing 114 deforms to drive the optical module 13 to deform, in one embodiment, the optical frame 11 is provided with an avoidance groove 111 corresponding to the optical machine 132, one end of the optical machine 132 away from the lens 133 extends into the avoidance groove 111, and the groove wall gap between the optical machine 132 and the avoidance groove 111 is set. Specifically, for realizing miniaturization of the product, the overall thickness of the mirror frame 11 is generally smaller, but the optical machine 132 may have a certain thickness, for facilitating installation of the optical machine 132, the mirror frame 11 is provided with an avoidance groove 111 corresponding to the optical machine 132, and one end of the optical machine 132, which is far away from the lens 133, extends into the avoidance groove 111, so that under the premise of realizing miniaturization of the product, installation of the optical machine 132 is facilitated, and the possibility that the rear shell 114 is deformed to drive the optical machine module 13 to deform is reduced, and the groove wall gap of the optical machine 132 and the avoidance groove 111 are arranged, so that the possibility that the avoidance groove 111 is slightly deformed to immediately push the optical machine 132 to shift is reduced.
Referring to fig. 3, the middle 131a of the lens frame 11 is fixed, the two lens legs 12 are pulled outwards by force F, so that the rear shell 114 is deformed, further, the angular deviation of the preset point (end point) of the lens frame 11 before and after the deformation is obtained, the preset point and the first longitudinal plane form an angle α1, the preset point and the second longitudinal plane form an angle α2, the preset point and the horizontal plane form an angle α3, the first longitudinal plane is parallel to the extending surface of the lens frame 11 and perpendicular to the horizontal plane, the first longitudinal plane is perpendicular to the extending surface of the lens frame 11, and the first longitudinal plane, the second longitudinal plane and the horizontal plane together form a space coordinate system, so as to obtain the following table:
With a length of 150mm for the frame 11, when the frame 11 receives a torque of 250 N.mm, the increment of α2 is the largest, and the deformation amount is calculated to be about 0.24mm. By the same token, the limit torque of the temple 12 can obtain the limit deformation of the frame 11 in different directions.
In an embodiment, referring to fig. 3 to 7, the avoidance groove 111 has a first side wall 111a located at the rear side of the optical bench 132, a second side wall 111b near the outer side of the temple 12, and a third side wall 111c near the inner side of the temple 12;

Specifically, as shown in fig. 5, the gap between the light machine 132 and the first sidewall 111a is D1, if the gap between the light machine 132 and the first sidewall 111a is smaller than 0.5mm, the gap may be smaller than the limit deformation of the frame 11, and further the first sidewall 111a may abut against the light machine 132, so that the light machine 132 may deform; if the gap between the light machine 132 and the first side wall 111a is greater than 1.5mm, the depth of the avoidance groove 111 may be too large, so that the size of the avoidance groove 111 is too large, which affects the wearing of the user and is not beneficial to miniaturization of the product. Preferably, the gap between the light engine 132 and the first sidewall 111a is 0.9mm.
The gap between the light engine 132 and the second side wall 111b is D2, and other electrical structures in the head-mounted display device 10 may need to be mounted or passed through, such as a circuit board, between the light engine 132 and the second side wall 111 b. Therefore, enough space needs to be reserved, if the gap between the light machine 132 and the second side wall 111b is smaller than 5mm, the gap formed finally may be smaller than the limit deformation of the frame 11, and further the second side wall 111b may abut against the light machine 132, so that the light machine 132 may deform; if the gap between the optical machine 132 and the second side wall 111b is greater than 6mm, the width of the avoidance groove 111 may be too large, so that the size of the avoidance groove 111 is too large, which affects the wearing of the user and is not beneficial to miniaturization of the product. Preferably, the gap between the light engine 132 and the second side wall 111b is 5.2mm.
If the gap between the light machine 132 and the third side wall 111c is smaller than 2mm, the gap may be smaller than the limit deformation of the frame 11, and thus the third side wall 111c may abut against the light machine 132, so that the light machine 132 may deform; if the gap between the optical machine 132 and the third side wall 111c is greater than 3mm, the width of the avoidance groove 111 may be too large, so that the size of the avoidance groove 111 is too large, which affects the wearing of the user and is not beneficial to miniaturization of the product. Preferably, the gap between the light engine 132 and the third side wall 111c is 2.4mm.
Further, the light machine 132 is fixed to one end of the rib 131b away from the middle 131a, the end of the lens frame 11 has a connection portion 112 connected to the temple 12, and the escape groove 111 is provided in the connection portion 112. Specifically, the light machine 132 is fixed to an end of the rib 131b away from the middle 131a, that is, the light machine 132 is disposed at a corner of the head-mounted display device 10, so that the wearing of the user is not affected, and the miniaturization of the head-mounted display device 10 can be realized. In order to facilitate the arrangement of the avoidance groove 111, the end of the mirror frame 11 is provided with a connecting portion 112 connected with the mirror leg 12, the avoidance groove 111 is arranged on the rear case 114, and the side wall of the front case 113 forms a second side wall 111b of the avoidance groove 111.

In one embodiment, the rib 131b is at least coated on the upper edge of the lens 133. Specifically, the rib 131b is at least coated on the upper edge of the lens 133, so as to ensure the mounting stability of the lens 133, and the rib 131b is configured in an arc shape to adapt to the shape of the lens 133. The rib 131b may cover only the upper edge of the lens 133, cover the upper edge and two opposite side edges of the lens 133, or cover the periphery of the lens 133.
