DETAILED DESCRIPTION
[0023] Below, the exemplary embodiments according to the present application will be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application, and it should be understood that the present application is not limited to the exemplary embodiments described herein.
[0024] Figure 1 This is a structural block diagram of a virtual reality device provided by an exemplary embodiment of the present application. Figure 1As shown, the virtual reality device 300 provided in this application may include a handle 200 and a head-mounted display device 100. The handle 200 is electrically connected to the head-mounted display device 100. The head-mounted display device 100 can be worn on the user's head and then present images in front of the user's eyes, guiding the user to feel as if they are in a virtual environment. In actual use, the user can control operations by holding the handle 200, and the image on the head-mounted display device 100 will change accordingly based on the signals sent by the handle 200.
[0025] Figure 2 This is a schematic diagram of the structure of a head-mounted display device provided by an exemplary embodiment of the present application. Figure 2 As shown, the head-mounted display device 100 may include a bracket assembly 110, a lens barrel assembly 130 and a screen 131. The bracket assembly 110 is provided with a lens 111, and the screen 131 is externally provided on the lens barrel assembly 130. The image on the screen 131 can be refracted into the user's eyes through the lens 111. The bracket assembly 110 and the lens barrel assembly 130 are detachably connected, so that the bracket assembly 110 can be easily replaced.
[0026] Figure 3 A comparison diagram of two bracket assemblies with different heights provided for an exemplary embodiment of the present application. Figure 4 This is a comparison diagram of two head-mounted display devices after assembling bracket assemblies of different heights according to an exemplary embodiment of the present application. Figure 3 and Figure 4 As shown, by replacing the bracket assembly 110, the lens barrel assembly 130 can be connected to different types of bracket assemblies 110 (such as Figure 3 As shown), it should be noted that different types of bracket assemblies 110 can be understood as having different heights from the bottom of the bracket assembly 110 to the top of the bracket assembly 110, with reference to Figure 3 , the bracket assembly 110 is Figure 3 In the placed state, Figure 3 The lower end of the middle bracket assembly 110 can be understood as the bottom of the bracket assembly 110, and the upper end of the bracket assembly can be understood as the top of the bracket assembly 110. Since the relative position of the lens 111 in the bracket assembly 110 and the bracket assembly 110 as a whole remains unchanged, when the lens barrel assembly 130 is connected to the bracket assembly 110 at different heights, the distance between the lens 111 and the screen 131 will also change (e.g. Figure 4 As shown), the clarity of the image seen by the user after wearing the head-mounted display device 100 will also change.
[0027] In actual application, the user can replace the bracket assembly 110 with a suitable height according to their own needs, so that the distance between the lens 111 and the screen 131 is appropriate, thereby obtaining a clearer image. In other words, if a myopic user uses the head-mounted display device 100 provided by this application, then the user can select a bracket assembly 110 of a corresponding height according to their own myopia degree, so that the lens 111 and the screen 131 are at a suitable distance, ensuring that the myopic user can obtain a clear image. In this way, when the myopic user wears the head-mounted display device 100, even if they do not wear myopia glasses, they can still obtain a clear image, which not only makes it easier for the user to wear the head-mounted display device 100, but also improves the user's experience.
[0028] The head-mounted display device 100 and virtual reality device 300 provided in the present application are detachably connected to the lens barrel assembly 130 via the bracket assembly 110, so that a myopic user can choose to assemble the bracket assembly 110 at an appropriate height according to his or her myopia degree, so that the lens 111 and the screen 131 are at an appropriate distance, ensuring that the myopic user can obtain a clear image. In this way, when wearing the head-mounted display device 100, the myopic user can obtain a clear image even without wearing myopic glasses, which not only makes it convenient for the user to wear the head-mounted display device 100, but also improves the user experience.
[0029] like Figure 2 As shown, the head-mounted display device 100 may further include a connecting frame 140 and a fastener 150, wherein the connecting frame 140 is connected to the aforementioned lens barrel assembly 130, and the fastener 150 is detachably connected to the support assembly 110 and the connecting frame 140. In other words, the support assembly 110 and the lens barrel assembly 130 are detachably connected via the connecting structure between the fastener 150 and the connecting frame 140. Specifically, after the fastener 150 connects the support assembly 110 and the connecting frame 140, the support assembly 110 and the connecting frame 140 are relatively fixed, and the assembly between the support assembly 110 and the lens barrel assembly 130 is completed. When it is necessary to replace the support assembly 110, the fastener 150 can be detached from the connecting frame 140, and the support assembly 110 can be separated from the lens barrel assembly 130. Then, the support assembly 110 of another height can be assembled on the lens barrel assembly 130 via the connecting structure between the fastener 150 and the connecting frame 140.
[0030] In one embodiment, the fastener 150 may include a bolt, a screw, a pin, or the like.
[0031] like Figure 2 As shown, the bracket assembly 110 is provided with a support ear 112, and a fastener 150 detachably connects the support ear 112 and the connecting frame 140. It should be understood that the support ear 112 can facilitate the assembly of the fastener 150, effectively improving the efficiency of installation and removal.
[0032] In one embodiment, threaded holes are provided on both the support ear 112 and the connecting frame 140 , and the fastener 150 is threadedly engaged with the threaded holes on both the support ear 112 and the connecting frame 140 .
[0033] In one embodiment, a threaded hole is provided on the connecting frame 140, and a light hole is provided on the support ear 112. After the fastener 150 passes through the light hole on the support ear 112, the passed portion is threadedly engaged with the threaded hole on the connecting frame 140. This not only achieves relative fixation between the bracket assembly 110 and the connecting frame 140, but also during the assembly process, the fastener 150 can directly pass through the light hole on the support ear 112, which can improve the assembly efficiency of the fastener 150.
[0034] like Figure 2 As shown, there are a plurality of lugs 112, which are distributed along the circumference of the bracket assembly 110. It should be understood that after assembly, each lug 112 is equipped with the aforementioned fastener 150, and each fastener 150 is used to connect the lug 112 to the connecting frame 140. This can improve the connection strength between the lug 112 and the connecting frame 140 in different directions, thereby improving the connection strength between the bracket assembly 110 and the lens barrel assembly 130, making it difficult for the assembled bracket assembly 110 and the lens barrel assembly 130 to separate relative to each other.
[0035] It should be noted that the “multiple” involved in this application can be understood as two or more.
[0036] Figure 5 This is a schematic diagram of the structure of a head-mounted display device provided by another exemplary embodiment of the present application. Figure 2 and Figure 5 As shown, the bracket assembly 110 includes a first side wall 113 and a second side wall 114 that are oppositely disposed, and the lens barrel assembly 130 includes a third side wall 132 and a fourth side wall 133 that are oppositely disposed. Figure 2 The first side wall 113 of the bracket assembly 110 and the third side wall 132 of the lens barrel assembly 130 are shown. Figure 5 The second side wall 114 of the support assembly 110 and the fourth side wall 133 of the lens barrel assembly 130 are shown. Figure 2 and Figure 5As shown, the first side wall 113 and the second side wall 114 are both provided with a support ear 112, and the third side wall 132 and the fourth side wall 133 are both connected to a connecting frame 140. The support ear 112 on the first side wall 113 is connected to the connecting frame 140 on the third side wall 132 through a fastener 150, and the support ear 112 on the second side wall 114 is connected to the connecting frame 140 on the fourth side wall 133 through a fastener 150. Since the first side wall 113 and the second side wall 114 are arranged opposite to each other, and the third side wall 132 and the fourth side wall 133 are arranged opposite to each other, after the bracket assembly 110 and the lens barrel assembly 130 are assembled, it is not easy for one side to be relatively tilted while the other side has a gap. The sealing between the bracket assembly 110 and the lens barrel assembly 130 can be enhanced, dust can be prevented from falling onto the screen 131, and the service life of the screen 131 can be extended.
[0037] In one embodiment, the number of the supporting ears 112 on the first side wall 113 may be one, two, three, etc. The number of the supporting ears 112 on the second side wall 114 may be one, two, three, etc.
[0038] like Figure 2 As shown, the positions of the first portion 115 and the second portion 116 of the bracket assembly 110 correspond to the corresponding two ends of the connecting frame 140. The first portion 115 and the second portion 116 are both provided with ears 112. The ears 112 on the first portion 115 and the ears 112 on the second portion 116 are respectively connected to the two ends of the connecting frame 140 via fasteners 150. In this way, for the connecting frame 140, both ends of the connecting frame 140 are connected to the fasteners 150, which makes it less likely that one end will be lifted, thereby improving the sealing performance between the bracket assembly 110 and the lens barrel assembly 130. In addition, for the bracket assembly 110 and the lens barrel assembly 130, both ends of the connecting frame 140 are connected to the fasteners 150, which can improve the connection stability between the assembled bracket assembly 110 and the lens barrel assembly 130, and make it less likely that they will separate from each other.
[0039] like Figure 2 and Figure 5 As shown, the lens barrel assembly 130 is also provided with a connecting shaft 134, and the connecting frame 140 can be slidably mounted on the connecting shaft 134. In this way, after the bracket assembly 110 and the lens barrel assembly 130 are assembled, the connecting frame 140 can move along its axial direction relative to the connecting shaft 134. Since the connecting shaft 134 is placed horizontally, during the sliding of the connecting frame 140 relative to the connecting shaft 134, the bracket assembly 110 can also move horizontally relative to the lens barrel assembly 130, so that the head-mounted display device 100 can adapt to different pupil distances, provide users with clearer images, and give users a better user experience.
[0040] Figure 6This is an exploded view of a head mounted display device provided by an exemplary embodiment of the present application. Figure 6 As shown, the bracket assembly 110 may include a bracket housing 117, a light strip 118, a reflective sheet 119, and a camera module 120. The bracket housing 117 is detachably connected to the lens barrel assembly 130. The light strip 118 and the reflective sheet 119 are both disposed within the bracket housing 117, and the camera module 120 is connected to the bracket housing 117. Specifically, after the user wears the head-mounted display device 100, the light strip 118 emits light. After the user's eyeball is illuminated by the light strip 118, an eye image is formed on the reflective sheet 119. The camera module 120 can then obtain the eye image on the reflective sheet 119, thereby facilitating the subsequent implementation of the eye tracking function.
[0041] like Figure 6 As shown, the bracket assembly 110 may further include a lamp cover 121 . The lamp cover 121 is disposed on the bracket housing 117 . The lamp cover 121 covers the light strip 118 . The lamp cover 121 may protect the light strip 118 .
[0042] like Figure 6 As shown, the lens barrel assembly 130 may include a lens barrel shell 135 and a dustproof sheet 136. The dustproof sheet 136 is provided on the lens barrel shell 135. The aforementioned screen 131 is externally provided on the lens barrel shell 135. The dustproof sheet 136 is located between the screen 131 and the bracket assembly 110. During the process of replacing the bracket assembly 110, the bracket assembly 110 and the lens barrel assembly 130 are separated from each other. The dustproof sheet 136 can prevent dust from falling onto the screen 131, thereby protecting the screen 131 and extending the service life of the screen 131.
[0043] The above description has been provided for the purpose of illustration and description. Furthermore, this description is not intended to limit the embodiments of the present application to the forms disclosed herein.
