6 is a view showing the principle of focus adjustment of the head-mounted display apparatus 100 of the present invention. Since the distance between the display unit 210 and the user's eye is short, the lens 250 adjusts the position of the image output from the display unit 210 to be positioned at the focal distance. However, the focal distance differs depending on the user's eyesight. In the case of nearsightedness, as shown in FIG. 6, since the image is formed in front of the retina, the focal distance must be further increased so that the image is formed on the retina and a clear image can be seen.

Adjusting the distance d between the lens 250 and the display unit 210 can change the focal distance. In general, the head-mounted display device changes the position of the display unit to adjust the focal distance, and in particular, it is difficult to adjust the focus of the left eye. In order to solve the above problem, the head-mounted display device 100 of the present invention uses a focus adjustment unit 227, 247 for adjusting the position of the lens 250 to adjust the distance between the lens 250 and the display unit 210 Adjust.

FIG. 7 is a perspective view showing the visual module 200, the horizontal adjustment section, and the focus adjustment section of the head-mounted display apparatus 100 of the present invention, and FIG. 8 is a cross-sectional view taken along line A-A of FIG. The barrel 240 is inserted into the barrel accommodating portion 225 of the display frame 220 and the focus adjusting portion moves the barrel 240 in the barrel accommodating portion 225 in the forward and backward direction, The distance between the lens 250 and the display unit 210 fixed to the display frame 220 is adjusted.

The focus adjustment part of the present invention is inserted into a screw hole 271 formed in the other one of the display frame 220 and the barrel 240 so as to be rotatable and rotatable and can move along the screw hole 271, . 7 and 8 illustrate a screw 271 that is fixed to the barrel 240 and has a screw hole 271 formed in the display frame 220. The barrel 240 is fixed to the display frame 220, A screw hole 271 may be formed in the screw hole 271.

A thread is formed on the outer surface of the screw 271, and a screw groove corresponding to the thread is formed on the inner surface of the screw 271. When the user rotates the screw 271, the thread of the screw 271 moves along the thread groove and the screw 271 moves in the forward and backward directions, and the barrel 240 fixed to the screw 271 moves to the barrel accommodating portion 225, As shown in FIG.

In order to facilitate the rotation of the screw 271, a disc-shaped wheel 272 which rotates the screw 271 can be used. One side of the wheel 272 is exposed to the outside of the housing 110 as shown in Figures 2 and 3 and the user pushes the wheel 272 exposed to the outside of the housing 110 in the left and right direction, . 8A shows a state in which the barrel 240 is positioned in the front direction, and FIG. 8B shows a state in which the barrel 240 is positioned in the rear direction. The barrel 240 is pulled out of the barrel accommodating portion 225 by the screw 271 as shown in FIG.

In order to prevent the user from unintentionally rotating the screw 271, the screw 271 may be made of a metal material, and a magnet 279 may be provided at a position adjacent to the screw 271 as shown in Fig. 8 have. The magnetic force of the magnet 279 causes the screw 271 to move only when a force of a predetermined magnitude or more is applied without moving easily.

The screw 271 is fixed to one side of the barrel 240 so that the barrel 240 is prevented from rotating in the barrel accommodating part 225 by the rotation of the screw 271 and the guide shaft 274 ) And a guide hole can be used. A first guide hole 242 formed in the barrel 240 and a guide shaft 274 inserted in the second guide hole 222 formed in the display frame 220 extend in the front and rear direction parallel to the screw 271 .

The barrel 240 can move along the first guide hole 242 and the second guide hole 222 when the barrel 240 moves in the forward and backward directions. When the first guide hole 242 is positioned in the front direction as shown in FIG. 7, the movement distance of the barrel 240 in the backward direction can be limited. That is, when the first guide hole 242 and the second guide hole 222 come into contact with each other, they do not move any more, and the gasket fixed to the end portion of the guide shaft 274 has the first guide hole 242, So that the barrel 240 moves too far forward to prevent the display unit 210 from touching.

9 is a view for explaining the positional relationship between the head-mounted display device 100 of the present invention and the user's eyes. It is necessary to adjust the interval of the pair of vision modules 200 according to the distance between the eyes, that is, the interpupillary distance (IPD), as well as the focal distance with the eyes. Since the 3D image is obtained by two different cameras, the pupil position and the center of the image coincide with each other by providing the 3D image to the left eye and the right eye, respectively, so that the user can accurately provide the 3D image.

Therefore, it is necessary to provide a horizontal adjustment unit for adjusting the distance of the pair of vision modules 200 according to the pupil distance of the user. In addition, since the distance between the left eye and the right eye differs from the nose to the nose for each user, the horizontal adjustment section, which moves independently of the horizontal adjustment section in which the visual module 200 on the left side and the visual module 200 on the right side move symmetrically, The module 200 can be disposed. In the visual module 200 of the present invention, the lens 250 and the display unit 210 are divided into left and right eyes, respectively, so that they can independently move, and the visual module 200 can be disposed at an accurate pupil position.

10 is a view for explaining the operation of the horizontal adjustment section of the head-mounted display apparatus 100 of the present invention. It is possible to adjust the interval between the eyes of the user by adjusting the left and right positions of the time module as shown in FIG. The left and right visual modules 200 can be respectively moved, and even when the distance from the nose to the eye is different between right and left eyes, the position can be adjusted to the correct position.

Since the barrel 240 and the lens portion of the visual module 200 are exposed in the back direction, an opening 113 is formed in the housing 110 so that the opening 113 can be moved in the left- As shown in FIG. 4, a spacer 280 is provided in the periphery of the barrel 240 in correspondence with the shape of the opening 113 to prevent the parts inside the housing 110 from being seen through the opening 113 can do. When the barrel 240 has a cylindrical shape as shown in Fig. 5, the opening 113 is formed in an elongated oval shape in the lateral direction, and the spacer 280 can be formed in the shape of a crescent moon.

The horizontal adjustment button 277 includes a button portion 277c located outside the housing 110, And a locking pawl 277d extending through the button opening 111 formed in the housing 110 in the locking pawl 277c. The locking pawl 277d engages with the time module 200 and is horizontally When the adjustment button 277 is moved in the left and right direction, the time module moves in the left and right direction relative to the housing 110.

The button opening 111 formed in the housing 110 is formed larger than the size of the fastening pawl 277d or the distance between the fastening pawls 277d located at both ends when two or more fastening pawls 277d are present And movement of the locking pawl 277d in the left and right direction is restricted when it touches the end of the button opening 111. [ The button portion 277c may be formed larger than the button opening 111 so that the button opening 111 is not exposed to the outside even when the horizontal adjustment button 277 moves left and right.

And may further include a rail 278 to prevent the visual module from being shaken when moving in the lateral direction. Referring to FIG. 4, the rail 278 is a bar-shaped member fixed to the housing 110 and extending in the left-right direction. The rail 278 is inserted laterally into the visual module 200 as shown in FIG. A groove for the rail 278 may be formed in the visual module 200 and a rail 278 may be interposed between the screw 271 and the display frame 220 as shown in FIG.

The magnet 279 can be used to prevent the visual module 200 from moving left and right along the rail 278 and moving the visual module 200 regardless of the user's intentions. In order for the rail 278 to move in the visual module 200, a force greater than a magnetic force must be applied. The magnet 279 may use a magnet 279 which limits the rotation of the screw described above. That is, one magnet 279 may be disposed adjacent to the screw and rail 278 to limit the horizontal movement of the time module 200 and the forward and backward movement of the barrel 240.

Alternatively, a latching groove (not shown) corresponding to the shape of the screw 271 is formed on the rail 278 so that the screw 271 can be moved in the lateral direction only when the screw 271 is fixed to the latching groove, .

When the leaf spring is used, the latching groove is resilient, so that the shape of the latching groove is changed when the user moves in the left and right direction, and the visual module 200 can be moved. A protrusion may be formed on the upper surface of the horizontal adjustment button 277 so that the frictional force between the finger and the horizontal adjustment button 277 can be increased when the user moves his finger to the left or right.

The horizontal adjustment button 277 may further include a wheel opening 277a for exposing the wheel 272 of the focus adjustment unit to the outside. The number of buttons exposed to the outside is minimized and the user simultaneously uses the wheel 272 and the horizontal adjustment button 277 positioned at the same position to adjust the position of the left and right positions of the time module 200 according to the pupil distance IPD And the distance between the lens 250 and the display unit 210 may be adjusted to adjust the focus.

As described above, according to at least one embodiment of the present invention, it is possible to adjust the focal distance in accordance with the visual acuity of the user and include a horizontal adjustment unit that matches the distance between the pair of lenses 250 and the interval between the pupils, You can enjoy 3D images comfortably.

In particular, according to the present invention, it is possible to control the left and right eye vision modules 200 and 200 in the left eye and the right eye independently, respectively, It can be finely adjusted.

The foregoing detailed description should not be construed in all aspects as limiting and should be considered illustrative. The scope of the present invention should be determined by rational interpretation of the appended claims, and all changes within the scope of equivalents of the present invention are included in the scope of the present invention.
