More specifically, thefirst positioning element 141 includes afirst ratchet 141a and asecond ratchet 141b on opposite sides thereof.

The drivenmember 142 includes ashaft portion 142a, agear 142b, asecond fixing portion 142c and a secondengaging portion 142 d. Theshaft portion 142a is rotatably disposed in thegroove 111a of thefirst housing 111 of thecase 110. Thegear 142b is connected to theshaft portion 142a and coupled to thefirst rack 123 of thefirst strap 120 and thesecond rack 133 of thesecond strap 130, such that when thefirst strap 120 and thesecond strap 130 change the total length L when overlapping, the displacement of thefirst rack 123 and thesecond rack 133 can rotate thegear 142b, so as to rotate the drivenelement 142. Thesecond fixing portion 142c is connected to theshaft portion 142a and is engaged with thefirst fixing portion 151 of thereset element 150. When the drivenmember 142 rotates, thesecond fixing portion 142c rotates to drive thefirst fixing portion 151, so that thereset member 150 accumulates potential energy.

The linkingrotary disc 143 has a first releasingportion 143a, a second releasingportion 143b, a firstabutting portion 143c, a secondabutting portion 143d and a firstengaging portion 143 e. The secondengaging portion 142d of the drivenmember 142 is generally hexagonal, the first engagingportion 143e of the linkingdial 143 is generally hexagonal, and the second engagingportion 142d is engaged with the first engagingportion 143e, so that the linking dial 143 can rotate along with the drivenmember 142.

Thesecond positioning member 144 has a firstelastic portion 144a, a firstengaging portion 144b, a secondelastic portion 144c, a secondengaging portion 144d, a first position-limitingportion 144e and a second position-limitingportion 144 f. The firstelastic portion 144a corresponds to thefirst release portion 143a of the interlockingdial 143. The firstengaging portion 144b is connected to the firstelastic portion 144a and corresponds to thefirst ratchet 141a of thefirst positioning member 141. The secondelastic portion 144c corresponds to thesecond release portion 143b of the interlockingdial 143. The secondengaging portion 144d is connected to the secondelastic portion 144c and corresponds to thesecond ratchet 141b of thefirst positioning member 141. The first pushingportion 143c of the linkingrotary disc 143 is coupled to the first position-limitingportion 144 e. The second pushingportion 143d of the linkingrotary disc 143 is coupled to the second limitingportion 144 f.

Fig. 5B is a perspective view of the adjustment device of fig. 5A with the first and second straps overlapping and the total length thereof increased. Fig. 5C is a perspective view of the adjustment device of fig. 5B after the total length of the first strap and the second strap is reduced when the first strap and the second strap are overlapped. For clarity and ease of illustration, some components are shown in phantom in fig. 5B and 5C.

Referring to fig. 1, 5A and 5B, as shown in the process of fig. 5A to 5B, when thehousing 110 is moved along the first direction D1 by an external force, the total length L of thefirst strap 120 and thesecond strap 130 when they are overlapped increases. In the head-mounteddisplay device 10 shown in fig. 1, when thefirst strap 120 and thesecond strap 130 of theadjustment device 100 overlap the total length L shown in fig. 5B, the head-mounteddisplay device 10 can be conveniently sleeved on the head of the user.

Referring to fig. 1, 5B and 5C, when the external force is removed from thehousing 110, the adjustingmodule 140 drives thehousing 110 to move along a second direction D2 (a direction toward the head of the user) opposite to the first direction D1, so that the total length L of thefirst strap 120 and thesecond strap 130 when overlapped is reduced and adapted to the head circumference of the user, and theadjusting module 140 temporarily fixes the position of thesecond strap 130 relative to thefirst strap 120.

In other words, theadjustment apparatus 100 of the embodiment can change the total length L of thefirst strap 120 and thesecond strap 130 overlapped with each other by pulling thehousing 110, and a roller knob for adjusting the circumference of the conventional head-mounted display device can be omitted, so that the overall appearance of theadjustment apparatus 100 can be more beautiful, and the overall thickness of theadjustment apparatus 100 is thinner, which is convenient for the user to lie on his back.

Fig. 6A to 6C illustrate the operation principle of the adjustment module of the adjustment device shown in fig. 5A to 5C. Referring to fig. 2A, fig. 3A, fig. 5A and fig. 6A, the adjustingmodule 140 in fig. 6A is defined as a default state. At this time, the first pushingportion 143c of the linking rotary table 143 is not pushed to the limit positions at the two ends of the first limitingportion 144e of thesecond positioning member 144, and the second pushingportion 143d of the linking rotary table 143 is not pushed to the limit positions at the two ends of the second limitingportion 144f of thesecond positioning member 144. The firstengaging portion 144b of thesecond positioning element 144 is coupled to thefirst ratchet 141a of thefirst positioning element 141, and the second engagingportion 144d of thesecond positioning element 144 is coupled to thesecond ratchet 141b of thefirst positioning element 141, so that thefirst strap 120 and thesecond strap 130 are positioned at the total length L shown in fig. 5A.

Referring to fig. 2A, 5B, 6A and 6B, the adjustingmodule 140 in fig. 6B is defined as a screwing process, which means a process of accumulating the energy of thereset element 150. When the user applies force to move thehousing 110 in the first direction D1, the total length L of thefirst strap 120 and thesecond strap 130 when they overlap increases. In the process of increasing the total length L of thefirst strap 120 and thesecond strap 130, thefirst rack 123 and thesecond rack 133 drive thegear 142 b. In the view of fig. 6B, the drivenmember 142 rotates clockwise.

At this time, the second engagingportion 142d of the drivenmember 142 drives the first engagingportion 143e of the linkingrotary disc 143, so that the linkingrotary disc 143 rotates clockwise along with the drivenmember 142. The first pushingportion 143c moves to the limit of one end of the first position-limitingportion 144e, and the second pushingportion 143d moves to the limit of one end of the second position-limitingportion 144 f. The first releasingportion 143a pushes the firstelastic portion 144a to elastically deform, so that the first engagingportion 144b is disengaged from thefirst ratchet 141a of thefirst positioning member 141. Meanwhile, the second releasingportion 143b of the linkingdial 143 is away from the secondelastic portion 144c of thesecond positioning member 144, and the second engagingportion 144d of thesecond positioning member 144 generates a ratchet action on thesecond ratchet 141b of thefirst positioning member 141.

Along with the clockwise rotation of the drivenmember 142, the second engagingportion 142d of the drivenmember 142 drives thefirst fixing portion 151 of thereset member 150 to rotate clockwise, so that thereset member 150 accumulates potential energy.

In other embodiments, the adjusting device may not be provided with a reset element, and the adjusting module may temporarily fix the position of the second strap relative to the first strap after the housing is moved in the first direction by an external force.

Referring to fig. 2A, fig. 5C, fig. 6B and fig. 6C, the adjustingmodule 140 in fig. 6C is defined as a releasing process, which means a process of enabling thereset element 150 to release the bit energy. The user may release the force applied to thehousing 110. At this time, since theadjusting module 140 accumulates a certain potential energy in the resettingelement 150 through the screwing process, when the external force is removed from thehousing 110, the resettingelement 150 releases the potential energy and rotates in the opposite direction, i.e., counterclockwise in the perspective of fig. 6C. Then, thereset member 150 drives the drivenmember 142 to rotate counterclockwise, and the drivenmember 142 drives the linkingturntable 143 to rotate counterclockwise through the cooperation of thesecond clamping portion 142d and thefirst clamping portion 143 e.

Similarly, the first abuttingportion 143c moves to the limit of the other end of the first position-limitingportion 144e, and the second abuttingportion 143d moves to the limit of the other end of the second position-limitingportion 144 f. The second releasingportion 143b pushes the secondelastic portion 144c to elastically deform, so that the second engagingportion 144d is disengaged from thesecond ratchet 141b of thefirst positioning member 141. Meanwhile, the first releasingportion 143a of the linkingdial 143 is away from the firstelastic portion 144a of thesecond positioning member 144, and the first engagingportion 144b of thesecond positioning member 144 generates a ratchet action on thefirst ratchet 141a of thefirst positioning member 141.

Then, thegear 142b of the drivenelement 142 rotates counterclockwise and drives thefirst rack 123 of thefirst strap 120 and thesecond rack 133 of thesecond strap 130, so as to reduce the total length L of thefirst strap 120 and thesecond strap 130.

In summary, the adjusting device of the present invention can achieve the effects of making the appearance of the head-mounted display device more beautiful, reducing the overall thickness of the structure behind the brain to facilitate the user to lie on his back, and being capable of being quickly stretched, worn, loosened, and fine-tuned.

Although the present invention has been described with reference to the above embodiments, it should be understood that the invention is not limited thereto, and that various changes and modifications can be made by those skilled in the art without departing from the spirit and scope of the invention.
