A head-mounted display device and an adjustment module are provided. The head-mounted display device includes a body and two adjustment modules. The two adjustment modules are configured to be assembled to two zoom lens groups of the body. Each of the adjustment modules includes a base, a sliding block, a first shape memory alloy (SMA) element, a first recovery element, a braking element, a second SMA element, and a second recovery element. The first SMA element is connected between the base and an actuating end of the sliding block and is configured to actuate the sliding block so that a transmission end of the sliding block drives the zoom lens group to zoom. The first recovery element is connected between the base and the actuating end and is configured to keep the sliding block at an original position when the first SMA element is in a power-off state. The braking element is engaged with a braking end of the sliding block when the braking element is in a braking position. The braking element is separated from the braking end when the braking element is in a movable position. The second SMA element is connected between the base and the braking element and is configured to actuate the braking element to move between the braking position and the movable position. The second recovery element is connected between the base and the braking element and is configured to keep the braking element at the braking position or the movable position when the second SMA element is in the power-off state.

Head-mounted display device and adjustment module

A head-mounted display device and a zoom lens module are provided. The zoom lens module includes a first fixing frame, an arc zoom ring, a second fixing frame, and a first non-circular lens. The first fixing frame has an arc segment and a non-arc segment connected to each other. The arc segment has a slot. The arc zoom ring is disposed on an inner side of the arc segment and capable of sliding in a circumferential direction of the arc segment. An outer side of the arc zoom ring has a slide bar. An inner side of the arc zoom ring has a guide block. The slide bar passes through the slot and is adapted to slide along the slot. The second fixing frame is disposed on an inner side of the first fixing frame and the arc zoom ring and capable of sliding in an axial direction of the arc segment. An outer side of the second fixing frame has a guide rail. The guide block is embedded in the guide rail and adapted to slide along the guide rail. The first non-circular lens is disposed on an inner side of the second fixing frame. The guide block drives the second fixing frame to slide in the axial direction of the arc segment in response to the arc zoom ring sliding in the circumferential direction of the arc segment.

Head-mounted display device and zoom lens module

A head-mounted device includes a host, a first cradle, a second cradle, a speaker, and a shape memory alloy element. The first cradle and the second cradle are connected to two opposite sides of the host. The speaker is movably disposed on the first cradle. The shape memory alloy element is connected between the speaker and the first cradle and is configured to move the speaker after being powered on and heated and shrinking.

Head-mounted device

A head-mounted display device includes a front assembly, a wearable assembly, and a cushion module. The wearable assembly is connected to the front assembly and is suitable for wearing the front assembly onto a face of a user. The cushion module includes a hard member, a soft member, and a fan. The hard member is connected to the wearable assembly. The soft member is connected to the hard member to contact skin of the user, and has a rear channel. The fan communicates with the rear channel. The soft member is connected to the hard member to contact the skin of the user, and the fan drives airflow to flow through the rear channel of the soft member to provide a heat dissipation effect.
