Description

Technical Field

[0001] This invention relates to a head-mounted display device. Background Technology

[0002] With the rapid advancement of technology, the types and functions of head-mounted display devices are becoming increasingly diverse. Taking the eye mask type of head-mounted display device as an example, when a user wears such a device, the gyroscope and position tracker inside the head-mounted display device will track the user's movement and project corresponding scene images, providing the user with an experience as if they were in a virtual world.

[0003] When using head-mounted displays, because each user has a different degree of myopia, the display can provide two zoom lens groups to accommodate different users and ensure the best user experience for each individual. Currently, head-mounted displays primarily use manual zoom lens groups for focusing. However, installing a face shield to improve comfort and stability prevents users from directly accessing the zoom lens groups for focusing. Summary of the Invention

[0004] This invention provides a head-mounted display device that can improve the problem of a face mask obstructing zooming.

[0005] The head-mounted display device of the present invention includes a main body, two adjustment rings, and a face mask. The main body has two zoom lens groups corresponding to the eyes. The two adjustment rings are detachably assembled to their respective zoom lens groups. The face mask is detachably assembled to the main body and is used to contact a user's face. The face mask has two adjustment knobs. Each adjustment knob is coupled to a corresponding adjustment ring and rotates the corresponding zoom lens group to zoom, and a portion of each adjustment knob is exposed to the outside for user operation.

[0006] In one embodiment of the present invention, each adjustment knob is a gear set.

[0007] In one embodiment of the invention, the head-mounted display device further includes a headband module having two opposing connection ends for detachably assembling to two temples of the body.

[0008] In one embodiment of the invention, the headband module also has a built-in battery.

[0009] In one embodiment of the present invention, the headband module further includes a communication module.

[0010] In one embodiment of the invention, the headband module further includes a head pad for contacting the back of the user's head.

[0011] Based on the above, in the head-mounted display device of the present invention, the mask has an adjustment knob so that the user can zoom via the adjustment knob. Attached Figure Description

[0015] Reference will now be made in detail to exemplary embodiments of the invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same element references are used in the drawings and description to denote the same or similar parts.

[0016] Figure 1 This is a schematic diagram of the assembly state of a head-mounted display device according to an embodiment of the present invention. Figure 2 yes Figure 1 This is a disassembled diagram of the head-mounted display device. Please refer to it. Figure 1 and Figure 2 The head-mounted display device 100 of this embodiment includes a main body 110, two adjustment rings 120, and a face mask 130. The main body 110 has two zoom lens groups 112 corresponding to the eyes. The two adjustment rings 120 are respectively used to be detachably assembled to the corresponding zoom lens group 112. The face mask 130 is used to be detachably assembled to the main body 110 and to contact a user's face. The face mask 130 has two adjustment buttons 132. Each adjustment button 132 is coupled to the corresponding adjustment ring 120 and rotates the corresponding zoom lens group 112 to zoom, and a portion of each adjustment button 132 is exposed to the outside for user operation.

[0017] In this embodiment, the face mask 130 is detachably assembled to the main unit 110. Therefore, when the user uses the head-mounted display device 100 in a static usage scenario, the face mask 130 can be removed to reduce weight, and other lightweight face masks can be used instead. On the other hand, when the user uses the head-mounted display device 100 in a scenario where there may be intense activity, or in an immersive scenario where isolation from the outside world is required, the face mask 130 can be assembled to the main unit 110. This not only improves the stability of wearing the head-mounted display device 100, but also blocks external light to reduce interference and provide a better immersive user experience.

[0018] Furthermore, in the head-mounted display device 100 of this embodiment, the two zoom lens groups 112 can be zoomed independently. When a user has myopia, the zoom lens group 112 can be zoomed to obtain a clear image. Moreover, even if the user's eyes have different degrees of myopia, the two zoom lens groups 112 can be zoomed to different degrees individually, allowing both eyes to obtain a clear image. When the mask 130 is not assembled to the main unit 110, the user can directly touch and rotate the zoom lens group 112 to zoom. When the mask 130 is assembled to the main unit 110, the user can still operate it by touching the exposed part of the adjustment knob 132. The operated adjustment knob 132 can drive the adjustment ring 120 to rotate the corresponding zoom lens group 112 to zoom. Therefore, regardless of whether the mask 130 is assembled to the main unit 110, the user can conveniently zoom the zoom lens group 112.

[0019] In this embodiment, the host device 110 is a lightweight head-mounted display similar to eyeglasses, which can be applied to fields such as virtual reality systems, augmented reality systems, or mixed reality systems. The host device 110 may include an optical system and protective housing, and may be equipped with or adapted to house a display. The aforementioned display may be a built-in display or an external portable display (e.g., a smartphone), but the invention is not limited thereto. The optical system includes optical components for altering the light path of the display, such as lenses, light guides, or prisms.

[0020] In this embodiment, the head-mounted display device 100 also includes a headband module 140 with two opposing connecting ends 142 for detachably attaching to the two temples 114 of the main body 110. For example, the connecting ends 142 and the temples 114 can be connected using Velcro or other methods. When the user uses the head-mounted display device 100 in situations where there may be vigorous movement, in addition to attaching the face mask 130 to the main body 110, the headband module 140 can also be attached to the main body 110. In this way, the face mask 130 and the headband module 140 can respectively contact the front and back of the user's head, providing wearing stability and comfort in a clamping manner, approaching the feel of an all-in-one device. Even if the user makes vigorous movements, the head-mounted display device can still be stably fixed to the user's head without worrying about falling or even being damaged.

[0021] In this embodiment, the length of the headband module 140 is adjustable. By adjusting the length of the headband module 140, users with different head circumferences can comfortably and securely wear the head-mounted display device 100. In this embodiment, the headband module 140 also has a built-in battery 144 electrically connected to the host unit 110. The host unit 110 itself may have a battery, but such a design would increase the weight of the host unit 110. Alternatively, the host unit 110 could be powered by an external power source, such as a computer or a power bank. However, the power source would affect the user's operating experience. With the headband module 140 having a battery 144, the head-mounted display device 100 does not need to be connected to an external power source, avoiding restrictions on the user's movements when using the head-mounted display device 100. Furthermore, this architecture also allows for a more balanced weight distribution of the head-mounted display device 100 on the user's head, resulting in better operational stability.

[0022] In this embodiment, the headband module 140 also includes a communication module 146 for receiving, for example, fifth-generation mobile communication signals or other wireless communication signals, enabling the host 110 to communicate with the outside world. In this embodiment, the headband module 140 may also include a headrest 148 for contacting the back of the user's head, providing more stable support.

[0023] Figure 3 yes Figure 1 A schematic diagram of the adjustment ring and adjustment knob of a head-mounted display device. Figure 3 Other components of the head-mounted display device are omitted to clearly illustrate the coupling relationship between the adjustment ring and the adjustment knob. Please refer to [reference needed]. Figure 1 and Figure 3 In this embodiment, each adjustment knob 132 is a gear set. For example, each adjustment knob 132 includes gear 132A and gear 132B. A portion of gear 132A is exposed to the outside for user operation. Gear 132A also meshes with gear 132B, and gear 132B meshes with rack 122 on adjustment ring 120. When the user rotates gear 132A, gear 132B is rotated by gear 132A, which in turn moves rack 122 to drive adjustment ring 120 to rotate, and adjustment ring 120 then rotates zoom lens assembly 112 to zoom.

[0024] In summary, in the head-mounted display device of the present invention, even with the face mask assembled to the main body, the user can still zoom via the adjustment knob on the face mask, eliminating the need to repeatedly remove the head-mounted display device to access the zoom lens assembly for zooming and then put it back on to check if the zoom state is ideal, thus improving ease of use. Furthermore, when combined with the detachable face mask and headband module, the head-mounted display device can be securely mounted on the user's head and is less likely to fall off. When using the head-mounted display device in relatively stable usage scenarios, the face mask and headband module can be removed to reduce weight, allowing for the use of other lightweight face masks.
