Description of Related Art

As the technology industry becomes increasingly developed, the types, functions and methods of use of display devices are becoming more and more diverse, and wearable display devices that can be directly worn on the body of the user have also emerged accordingly. There are many types of head-mounted display devices. Taking a glasses-type of the head-mounted display device as an example, after the user wears this type of display device, in addition to seeing three-dimensional images, the image also changes as the head of the user rotates, which may provide the user with a more immersive experience. However, when the user is playing games and the movements are too intense, a pair of temples of the glasses-type of the head-mounted display device may not provide sufficient clamping force. Therefore, an additional headband module assembled to an end of the temple may be provided to reduce the risk of the glasses-type of the head-mounted display device falling.

The aforementioned display may be a built-in display or an external portable display (such as a smartphone, etc.), but the disclosure is not limited thereto. The optical system includes optical elements used to change a light path of the display, such as lenses, light guides, or prisms.

Please refer toFIG.1andFIG.2. In this embodiment, the wearable device100further includes a side head strap module120. The side head strap module120is connected to the host110to position the host110on the face of the user. In order to assist the stability of the host110, a weight of the host110is shared, and the pressure exerted on the user by the side head strap module120is reduced. The wearable device100further includes an upper head strap module130.

Please refer toFIG.1,FIG.2,FIG.3, andFIG.4. In this embodiment, the upper head strap module130includes a sliding base131, a front buckle132, and an upper head strap133.

The sliding base131is detachably coupled to the sliding rail111and slides along the sliding rail111. The host110has a sliding rail111. The sliding rail111has a first engaging part111a(for example, a clamping block, as shown inFIG.3). The sliding base131has a second engaging part131a(for example, a hook, as shown inFIG.4). The engagement between the first engaging part111aand the second engaging part131atemporarily fixes the sliding base131to the sliding rail111. The front buckle132is pivotally connected to the sliding base131. The upper head strap133is connected between the side head strap module120and the front buckle132, as shown inFIG.2.

Please refer toFIG.3,FIG.5A, andFIG.5B. In this embodiment, the sliding rail111may have a track slit111b. The track slit111bhas an open section S1, a transition section S2, and a locking section S3. The open section S1may be an original heat dissipation hole of the host110. In other words, the original heat dissipation hole is used as a part of a fixed structure of the upper head strap module130without changing the appearance of the host110as much as possible. Specifically, the open section S1, the transition section S2, and the locking section S3are connected in sequence. A width of the open section SI may be greater than a width of the locking section S3. A length of the open section S1and a length of the locking section S3may be greater than a length of the transition section S2. The sliding base131may have a sliding part131b (as shown inFIG.4andFIG.7). Since the width of the open section S1is greater than the width of the locking section S3, the sliding part131bmay enter the track slit111bfrom the open section S1of the track slit111b. The sliding part131bslides along the transition section S2and the locking section S3of the track slit111buntil the first engaging part111aengages with the second engaging part131a, as shown inFIG.6AandFIG.6B.

Please refer toFIG.3,FIG.4, andFIG.7. In this embodiment, the sliding rail111may have a track groove111c. The track groove111ccommunicates with the track slit111b. The sliding base131has a base part131cand an anti-separation part131d. The sliding part131bis connected between the base part131cand the anti-separation part131d. The front buckle132is pivotally connected to the base part131cof the sliding base131. The anti-separation part131d slides in the track groove111calong the sliding part131b. When the sliding part131bslides along the locking section S3of the track slit111b, the cooperation between the anti-separation part131dand the track groove111crestricts the base part131cfrom being disengaged from the sliding rail111.

Please refer toFIG.6A,FIG.6B, andFIG.7. In this embodiment, if the sliding base131is planned to be disengaged from the sliding rail111, the force is applied on the host110and the sliding base131to release the engagement between the first engaging part111aand the second engaging part.131a. Next, the sliding part131bof the sliding base131slides from the locking section S3(as shown inFIG.3) of the track slit111bto the open section S1(as shown inFIG.3) of the track slit111b, so that the anti-separation part131dno longer interlocks with the track groove111cand may be disengaged upward from the open section S1of the track slit111b. At this time, the sliding base131may be disengaged from the sliding rail111.

Please refer toFIG.3,FIG.4, andFIG.7. The first engaging part111ais located in the track groove111c. The second engaging part131ais elastically connected to the sliding part131b. When the sliding part131bslides along the locking section S3of the track slit111b, the second engaging part131ais pushed by the first engaging part111arelative to the track groove111cuntil the second engaging part131aengages with the first engaging part111a.

In this embodiment, the side head strap module120may include a headrest121and a pair of side head straps122. The pair of side head straps122are respectively connected between opposite sides of the host110and opposite sides of the headrest121. The upper head strap133may be connected between the front buckle132and the headrest121. Specifically, the headrest121may have a rear buckle121a. Both ends of the upper head strap133may be connected to the rear buckle121a and the front buckle132respectively through detachable connection means (for example, Velcro or buckles).

Please refer toFIG.8andFIG.9. The embodiments ofFIG.8andFIG.9are similar to the embodiments shown inFIG.1andFIG.7. The difference between the two lies in that the sliding base131of the embodiments ofFIG.8andFIG.9may further have a limiting part131e. The limiting part131eis connected to the base part131c. The limiting part131eextends from a top surface110aof the host110to a front surface110bof the host110. The first engaging part111aand the second engaging part131aare located between the sliding part131band the limiting part131e. The limiting part131emay restricts the base part131cfrom being disengaged from the sliding rail111.

In summary, an upper head strap module may be used as an accessory of a wearable device and may be installed, removed, or replaced according to the needs of the user. Therefore, an upper head strap of the upper head strap module may be designed with different sizes and appearances, and so the user may choose the upper head strap module to be installed according to personal head shape and preferences. In addition, an open section of a track slit may be an original heat dissipation hole of a host, so that the original heat dissipation hole may be used as a part of a fixed structure of the upper head strap module without changing the appearance of the host.
