[0002] A head-mounted display is a near-eye display device, which has wide applications in fields such as augmented reality, virtual reality, and stereoscopic display. When the head-mounted display is applied to the field of augmented reality, the head-mounted display generally includes a camera and an eyepiece. The external information acquired by the camera is superimposed on the virtual information of the eyepiece, so as to skillfully integrate the virtual information with the real world.

[0003] Since the interpupillary distances of users are different, it is necessary to adjust the position of the eyepiece in the head-mounted display so that the head-mounted display can be suitable for users with different interpupillary distances. However, after adjusting the position of the eyepiece, the optical axes of the camera and the eyepiece in the head-mounted display are prone to deviation. In this case, there is a deviation between the external information observed by using the head-mounted display and the real external information, which affects the user's wearing experience.

The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0043] A head mounted display is a near-eye display device, which has a wide range of applications in the fields of augmented reality, virtual reality, and stereoscopic display. In order to provide users with a more comfortable wearing experience, the head mounted display has one or more of the following functions: focus adjustment for users with different vision, pupil distance adjustment for users with different pupil distances, headband adjustment for users with different head circumferences, face piece adjustment for users with different face shapes, and nose pad adjustment for users with different nose shapes.

[0044] When a head-mounted display is applied to the field of augmented reality, the head-mounted display includes a camera and an eyepiece. The external information obtained by the camera and the virtual information of the eyepiece are superimposed on each other, thereby cleverly integrating the virtual information with the real world. However, for existing head-mounted displays, after the position of the eyepiece is adjusted using the pupil distance adjustment mechanism, the optical axis of the camera and the optical axis of the eyepiece are prone to deviation. In this case, the external information observed by the head-mounted display deviates from the real external information, and the user will feel dizzy, which seriously affects the user's wearing experience.

[0045] In order to at least partially solve one or more of the above-mentioned problems and other potential problems, the present application proposes a display device. Specifically, a display device is proposed that enables a camera module to move with the eyepiece assembly to ensure that the optical axis of the camera module always coincides with the optical axis of the eyepiece.

[0046] Figure 1 , Figure 3 and Figure 4 The schematic diagrams of the structures of the display device 100 according to the exemplary embodiments of the present application are shown respectively. The display device 100 may be augmented reality (AR) glasses applied in various fields.

[0047] refer to Figure 1 , Figure 3 and Figure 4 , the display device 100 may include an eyepiece assembly 110, a camera module 120, and a first adjustment mechanism 130. The eyepiece assembly 110 may include a bracket 111 and an eyepiece 112, and the eyepiece 112 is fixed to the bracket 111. The camera module 120 may be located on a side of the bracket 111 away from the eyepiece 112. The first adjustment mechanism 130 may be located on a side of the bracket 111 away from the eyepiece 112, and connected to the camera module 120. The first adjustment mechanism 130 is used to make the camera module 120 follow the eyepiece assembly 110 so that the optical axis of the camera module 120 coincides with the optical axis of the eyepiece 112.

[0048] The display device 100 provided by the present application can ensure that the optical axis of the camera module 120 always coincides with the optical axis of the eyepiece 112 by making the camera module 120 follow the eyepiece assembly 110, avoiding the deviation between the external information observed by using the display device 100 and the real external information, reducing the dizziness feeling generated when the user wears the display device 100, and improving the wearing experience of the user.

[0049] To further elaborate on the spatial relationship of the components in the display device 100, the following will Figures 1 to 7 give an example of the display device 100.

[0050] In some embodiments, referring to Figure 1 , Figure 3 and Figure 4 , the number of the eyepiece assemblies 110 can be two. The two eyepiece assemblies 110 may include a first eyepiece assembly and a second eyepiece assembly. The first eyepiece assembly corresponds to the user's left eye, and the second eyepiece assembly corresponds to the user's right eye. The first eyepiece assembly may include a first bracket and a first eyepiece, and the first eyepiece is fixed on the first bracket. The second eyepiece assembly may include a second bracket and a second eyepiece, and the second eyepiece is fixed on the second bracket.

[0051] In some embodiments, referring to Figure 1 , Figure 3 and Figure 4 , the number of the camera modules 120 can be two. The two camera modules 120 may include a first camera module and a second camera module. The first camera module corresponds to the first eyepiece and is located on the side of the first bracket away from the first eyepiece. The second camera module corresponds to the second eyepiece and is located on the side of the second bracket away from the second eyepiece.

[0052] In some embodiments, referring to Figure 3 and Figure 4 , the display device 100 may further include a second adjustment mechanism 140, and the second adjustment mechanism 140 is used to adjust the distance between the two eyepiece assemblies 110. By adjusting the distance between the two eyepiece assemblies 110 through the second adjustment mechanism 140, the distance between the two eyepieces 112 can be made equal to the user's interpupillary distance.

[0053] In some embodiments, referring to Figure 4, the second adjustment mechanism 140 may include a transmission gear 141 and two transmission racks 142. The transmission gear 141 may be disposed between two brackets 111. The two transmission racks 142 are respectively disposed on the two brackets 111 and are located on opposite sides of the transmission gear 141 in a preset direction, and the preset direction is a direction perpendicular to the plane formed by the optical axis of the eyepiece 112 and the arrangement direction of the two eyepiece assemblies 110. Each transmission rack 142 extends along the arrangement direction of the two eyepiece assemblies 110 and includes a tooth-shaped structure 143 for cooperating with the transmission gear 141. The tooth-shaped structures 143 of the two transmission racks 142 are respectively engaged with the transmission gear 141. When the transmission gear 141 rotates circumferentially, the transmission gear 141 can drive the two brackets 111 to move towards each other or away from each other in the arrangement direction of the two eyepiece assemblies 110.

[0054] Specifically, the two transmission racks 142 may include a first transmission rack and a second transmission rack. The first transmission rack may be disposed on the first bracket and includes a first tooth-shaped structure. The second transmission rack may be disposed on the second bracket and includes a second tooth-shaped structure. The first tooth-shaped structure and the second tooth-shaped structure are disposed facing each other. Rotating the transmission gear 141 can drive the first transmission rack and the second transmission rack to move towards each other or away from each other in the arrangement direction of the two eyepiece assemblies 110, thereby driving the first bracket and the second bracket to move towards each other or away from each other in the arrangement direction of the two eyepiece assemblies 110, and realizing the adjustment of the distance between the two eyepiece assemblies 110.

[0055] In some embodiments, referring to Figure 1 and Figure 2 , the number of the first adjustment mechanisms 130 may be two. One first adjustment mechanism 130 corresponds to the first eyepiece assembly, and the other first adjustment mechanism 130 corresponds to the second eyepiece assembly. Each first adjustment mechanism 130 may include a first support arm 131. The first support arm 131 is fixed on the side of the bracket 111 away from the eyepiece 112 and is connected to the imaging module 120. The first support arm 131 can follow the movement of the bracket 111, and then drive the imaging module 120 to move together with the bracket 111, so as to ensure that the optical axis of the imaging module 120 always coincides with the optical axis of the eyepiece 112.

[0056] In some embodiments, referring to Figure 1 and Figure 2 , the first adjustment mechanism 130 may include a first support arm 131 and an adjustment screw 132. The first support arm 131 is located on the side of the bracket 111 away from the eyepiece 112 and is connected to the imaging module 120. The adjustment screw 132 extends in a direction perpendicular to the optical axis of the eyepiece 112 (i.e., the arrangement direction of the two eyepiece assemblies 110) and is threadedly connected to the first support arm 131.

[0057] Specifically, the first support arm 131 may include a support portion 1311 and an extension portion 1312. The support portion 1311 is disposed on the bracket 111 and extends along the optical axis of the eyepiece 112. The extension portion 1312 extends from the end of the support portion 1311 away from the bracket 111 along a preset direction, and the preset direction is a direction perpendicular to the plane formed by the optical axis of the eyepiece 112 and the arrangement direction of the two eyepiece assemblies 110. The extension portion 1312 may include a first threaded channel, and the imaging module 120 is mounted on the side of the extension portion 1312 away from the bracket 111. The adjusting screw 132 passes through the first threaded channel and is threadedly connected to the extension portion 1312. The first support arm 131 can follow the bracket 111, thereby driving the imaging module 120 to move along with the bracket 111 in the arrangement direction of the two eyepiece assemblies 110, ensuring that the optical axis of the imaging module 120 always coincides with the optical axis of the eyepiece 112.

[0058] In some embodiments, the first support arm 131 is slidably connected to the bracket 111, that is, the first support arm 131 can move relative to the bracket 111 in the extending direction of the adjusting screw 132. The circumferential rotation of the adjusting screw 132 drives the first support arm 131 and the imaging module 120 to move in the extending direction of the adjusting screw 132. When the adjusting screw 132 is rotated circumferentially, the circumferential rotation of the adjusting screw 132 can be converted into the movement of the first support arm 131 in the extending direction of the adjusting screw 132, thereby driving the imaging module 120 to move along the extending direction of the adjusting screw 132, facilitating the adjustment of the position of the imaging module 120 relative to the eyepiece 112, and further ensuring that the optical axis of the imaging module 120 coincides with the optical axis of the eyepiece 112.

[0059] As an example, the first support arm 131 is provided with a first protrusion, the bracket 111 is provided with a first groove for cooperating with the first protrusion, and the first groove extends a predetermined length in the extending direction of the adjusting screw 132. The first protrusion can be fitted into the first groove. By driving the first support arm 131 to move along the extending direction of the first groove, the position of the imaging module 120 relative to the eyepiece 112 can be adjusted.

[0060] As an example, the first support arm 131 is provided with a second groove, the bracket 111 is provided with a second protrusion for cooperating with the second groove, and the second protrusion extends a predetermined length in the extending direction of the adjusting screw 132. The second groove can be sleeved around the second protrusion. By driving the first support arm 131 to move along the extending direction of the second protrusion, the position of the imaging module 120 relative to the eyepiece 112 can be adjusted.

[0061] It should be noted that the present application does not specifically limit the structures of the first support arm 131 and the bracket 111. Any structure capable of adjusting the position of the camera module 120 relative to the eyepiece 112 may fall within the protection scope of the present application.

[0062] In some embodiments, the first support arm 131 is movable relative to the bracket 111 in a direction parallel to the optical axis of the eyepiece 112. In other words, the distance between the camera module 120 and the eyepiece 112 on the optical axis of the eyepiece 112 is adjustable.

[0063] In some embodiments, referring to Figure 3 , Figure 4 , Figure 5 and Figure 6 , the first adjustment mechanism 130 may include a second support arm 133, an adjustment screw 132, a fixed seat 134, and a guide rail structure 135. The second support arm 133 is located on the side of the bracket 111 away from the eyepiece 112. The adjustment screw 132 extends in a direction perpendicular to the optical axis of the eyepiece (i.e., the arrangement direction of the two eyepiece assemblies 110) and is threadedly connected to the second support arm 133. The guide rail structure 135 extends along the extension direction of the adjustment screw 132. The fixed seat 134 is sleeved around the adjustment screw 132 and is threadedly connected to the adjustment screw 132. The fixed seat 134 is mounted with the camera module 120. The fixed seat 134 is configured with a slider that cooperates with the guide rail structure 135. Among them, the second support arm 133 follows the bracket 111, and the movement of the second support arm 133 can drive the adjustment screw 132 to rotate circumferentially. The circumferential rotation of the adjustment screw 132 drives the fixed seat 134 and the camera module 120 to move along the extension direction of the adjustment screw 132.

[0064] The second support arm 133 can follow the bracket 111, thereby driving the adjustment screw 132 to rotate circumferentially. When the adjustment screw 132 rotates circumferentially, since the fixed seat 134 is provided with a slider that cooperates with the guide rail structure 135, the fixed seat 134 cannot rotate circumferentially with the adjustment screw 132 and can only move along the extension direction of the guide rail structure 135, thereby driving the camera module 120 to move along the extension direction of the guide rail structure 135, which is convenient for ensuring that the optical axis of the camera module 120 coincides with the optical axis of the eyepiece 112.

[0065] As an example, as shown in Figure 3 and Figure 5 , a second threaded channel is provided on the side of the second support arm 133 away from the bracket 111. The adjustment screw 132 passes through the second threaded channel and is threadedly connected to the second support arm 133.

[0066] As an example, as shown in Figure 3 and Figure 4As shown, the fixed seat 134 is provided with a third threaded channel. The adjusting screw 132 passes through the third threaded channel and is threadedly connected to the fixed seat 134.

[0067] As an example, the guide rail structure 135 can be a convex structure, and the slider of the fixed seat 134 is configured with a groove structure that cooperates with the convex structure. Alternatively, the guide rail structure 135 can be a groove structure, and the slider of the fixed seat 134 is configured with a convex structure that cooperates with the groove structure.

[0068] It should be noted that the present application does not specifically limit the structures of the second support arm 133 and the fixed seat 134. Any structure that can enable the imaging module 120 to move along the extension direction of the adjusting screw 132 to ensure that the optical axis of the imaging module 120 coincides with the optical axis of the eyepiece 112 can be within the protection scope of the present application.

[0069] In some embodiments, referring to Figure 2 、 Figure 6 and Figure 7 , the adjusting screw 132 may include a threaded section 1321, at least one main body section 1322, and a plugging portion 1323. The display device 100 may further include a main board and a guide plate 150. The main board is disposed between the eyepiece 112 and the imaging module 120. The guide plate 150 is disposed on the side of the bracket 111 or the main board away from the eyepiece 112 and includes a guide channel 151 for the main body section 1322 of the adjusting screw 132 to pass through. The main body section 1322 passes through the guide channel 151 and is connected to the guide plate 150. The threaded section 1321 is threadedly connected to the first support arm 131. Alternatively, the threaded section 1321 is threadedly connected to the second support arm 133 and the fixed seat 134 respectively. When the second support arm 133 follows the bracket 111 and drives the adjusting screw 132 to rotate circumferentially, the main body section 1322 of the adjusting screw 132 can move relative to the guide plate 150 in the extension direction of the adjusting screw 132.

[0070] As an example, the radial dimension of the plugging portion 1323 can be greater than the radial dimension of the main body section 1322. The radial dimension of the guide channel 151 can be greater than or equal to the radial dimension of the main body section 1322 and less than the radial dimension of the plugging portion 1323, so that the guide channel 151 can allow the main body section 1322 to pass through, but not allow the plugging portion 1323 to pass through.

[0071] As an example, the adjusting screw 132 sequentially includes a threaded section 1321, a main body section 1322, and a plugging portion 1323 in its extension direction.

[0072] As an example, the adjusting screw 132 sequentially includes a main body section 1322, a threaded section 1321, a main body section 1322, and a plugging section 1323 in its extending direction. In other words, a main body section 1322 is provided at each end of the adjusting screw 132, the threaded section 1321 is disposed between the two main body sections 1322, and a plugging section 1323 is provided on one side of a main body section 1322 away from the threaded section 1321.

[0073] In some embodiments, referring to Figure 4 , the display device 100 may further include a support rod 160, and the support rod 160 is disposed on a side of the bracket 111 or the main board away from the eyepiece 112. One end of the adjusting screw 132 is connected to the guide plate 150, and the other end is connected to the support rod 160. By fixing the two ends of the adjusting screw 132 to the guide plate 150 and the support rod 160 respectively, the position of the adjusting screw 132 in the vertical direction can be relatively fixed when it rotates circumferentially.

[0074] In some embodiments, referring to Figure 5 and Figure 6 , the guide rail structure 135 is connected to the guide plate 150 and the second support arm 133 respectively on both sides in its extending direction. For example, the second support arm 133 is provided with a connecting portion 1331, the guide plate 150 is provided with a clamping portion, one end of the guide rail structure 135 can be connected to the second support arm 133 through the connecting portion 1331, and the other end of the guide rail structure 135 is fixed in the clamping portion of the guide plate 150.

[0075] As an example, in a direction parallel to the optical axis of the eyepiece 112, the second support arm 133 and the guide plate 150 are movable relative to the bracket 111. In other words, the distance between the camera module 120 and the eyepiece 112 on the optical axis of the eyepiece 112 is adjustable. When adjusting the position of the camera module 120 on the optical axis of the eyepiece 112 by using the guide plate 150 and the second support arm 133, since the guide rail structure 135 is fixed to the guide plate 150 and the second support arm 133, the guide rail structure 135 and the camera module 120 can move simultaneously, so as to ensure that the slider of the fixed seat 134 always cooperates with the guide rail structure 135.

[0076] In some embodiments, referring to Figure 4 and Figure 6, the display device 100 may further include a distance measurement module 170 and a control module (not shown). The distance measurement module 170 is used to obtain the user's pupil distance information. The user's pupil distance information refers to the pupil distance of the user wearing the current display device 100, and the user's pupil distance can be calculated based on the pupil positions of the user's left and right eyes. The distance measurement module 170 may be a Hall sensor. The control module is communicatively connected to the distance measurement module 170 and the second adjustment mechanism 140 respectively. After receiving the pupil distance information detected by the distance measurement module 170, the control module controls the second adjustment mechanism 140 and adjusts the distance between the two eyepiece assemblies 110 through the second adjustment mechanism 140.

[0077] In some embodiments, the display device 100 may further include two headband structures (not shown), which are respectively disposed on the two eyepiece assemblies 110. Through the above headband structures, the user can wear the above display device 100.

[0078] The above are only exemplary embodiments of the present application. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present application, several improvements and substitutions can be made, and these improvements and substitutions should also be regarded as the protection scope of the present application.
