[0001] The invention relates to a head-mounted device and a headband. Background Art
[0002] In recent years, the application of virtual reality (VR) and augmented reality (AR) has become more and more popular, and there are many types of head-mounted devices. In existing head-mounted devices, a fixed headband is mainly used to fix the entire device on the user's head. However, each user has a different head shape, and the position of the headband that should contact the head for a comfortable and stable wearing feeling also varies from person to person. Therefore, how to make the head-mounted device be stably worn on the heads of different users and provide users with a comfortable wearing feeling is an important topic in this field. Summary of the invention
[0003] The present invention is directed to a head-mounted device and a headband, which has a rotatable headband to meet different needs of different users.
[0004] The head-mounted device of the present invention comprises a host and a headband. The host has two connecting parts located on opposite sides. The headband has two connecting ends located on opposite sides. The connecting ends are detachably and rotatably connected to the connecting parts. A first buckle part of each connecting end is rotatably buckled with a second buckle part of the corresponding connecting part. When the headband rotates to a detachable position relative to the host, the first buckle part is separated from the second buckle part.
[0005] The headband of the present invention is used for a head-mounted device. The head-mounted device includes a host. The host has two connecting parts located on opposite sides. The headband has two connecting ends located on opposite sides. The connecting ends are detachably and rotatably connected to the connecting parts. A first buckle part of each connecting end is rotatably buckled with a second buckle part of the corresponding connecting part. When the headband rotates to a detachable position relative to the host, the first buckle part is separated from the second buckle part.
[0006] In one embodiment of the present invention, each connection end includes a housing, a first snap-fit member and a turntable. The first snap-fit member is disposed in the housing. The first snap-fit member is used to move in an axial direction relative to the housing. The first snap-fit portion of the first snap-fit member is used to protrude from the housing and snap-fit the corresponding second snap-fit portion. The first snap-fit portion of the first snap-fit member is also used to retract into the housing and separate from the corresponding second snap-fit portion. The turntable is rotatably connected to the first snap-fit member. The first snap-fit member is used to move in an axial direction relative to the turntable. A third snap-fit portion of the turntable is used to snap-fit a fourth snap-fit portion of the corresponding connection portion so that the turntable cannot rotate relative to the connection portion.
[0007] In one embodiment of the present invention, the surface of the turntable facing the first buckle has an arc-shaped groove. The surface of the first buckle facing the turntable has an arc-shaped convex rib. When the headband rotates to a detachable position relative to the host, the arc-shaped convex rib slides into the arc-shaped groove and the first buckle part retracts into the shell. When the headband leaves the detachable position relative to the host, the arc-shaped convex rib keeps the turntable away from the first buckle and the first buckle part protrudes from the shell.
[0008] In one embodiment of the present invention, each connecting end further includes a second snap-on component. The second snap-on component is disposed in the housing. The second snap-on component is used to move axially relative to the housing. A fifth snap-on portion of the second snap-on component is used to protrude from the housing and snap-on a sixth snap-on portion of the corresponding connecting portion. The fifth snap-on portion of the second snap-on component is also used to retract into the housing and separate from the sixth snap-on portion. The turntable is rotatably connected to the second snap-on component and is located between the first snap-on component and the second snap-on component. When the turntable rotates relative to the connecting end, the first snap-on component and the second snap-on component move in opposite directions axially relative to the turntable.
[0009] In one embodiment of the present invention, the rotating disk has a protrusion, and the corresponding housing has a limiting portion. The cooperation between the protrusion and the limiting portion is used to limit the rotation angle of the rotating disk relative to the connecting end.
[0010] Based on the above, in the head mounted device and the headband of the present invention, the headband can rotate relative to the host and is detachable, suitable for users with different head shapes, and the headband can also be replaced according to the usage scenario.

[0019] Reference will now be made in detail to exemplary embodiments of the present invention, examples of which are illustrated in the accompanying drawings. Whenever possible, the same reference numerals are used in the drawings and the description to refer to the same or like parts.
[0020] Figure 1 FIG. 4 is a schematic diagram of a scenario in which a head mounted device according to an embodiment of the present invention is worn on a user's head. Figure 2 yes Figure 1 A schematic diagram of another scenario in which the head mounted device is worn on the user's head. Please refer to Figure 1 and Figure 2 The head mounted device 100 of the present embodiment includes a host 110 and a headband 120. The headband 120 is rotatably connected to the host 110. Figure 1 The headband 120 is connected to the host 110 in a horizontal state, so the headband 120 mainly contacts the back of the user's 50 head. Figure 2 The headband 120 is connected to the host 110 in an inclined state, so the headband 120 mainly contacts the back of the head of the user 50. It can be seen that when the user 50 wears the head mounted device 100 of this embodiment, the headband 120 can be rotated according to his / her own preferences to contact different parts of the back of the head, thereby obtaining the most comfortable wearing feeling.
[0021] FIG. 3A to FIG. 3D yes Figure 1 Schematic diagram of the four states of the head mounted device. Figure 3A The host 110 has two connecting parts 112 located on opposite sides. The headband 120 has two connecting ends 122 located on opposite sides. FIG. 3A to FIG. 3D Due to the viewing angle, only one connecting portion 112 and one connecting end 122 can be seen, but those skilled in the art can easily understand the specific positions of the two connecting portions 112 and the two connecting ends 122. Each connecting end 122 is detachably and rotatably connected to the connecting portion 112. Please refer to Figure 3B Because the connecting end 122 is rotatably connected to the connecting portion 112, the headband 120 can be rotated to an inclined position relative to the host 110. Figure 3C , the headband 120 can continue to rotate relative to the host 110 to a nearly vertical position, that is, a detachable position. Figure 3D When the headband 120 is rotated to a nearly vertical detachable position relative to the host 110, the headband 120 can be detached from the host 110 because the connecting end 122 is detachably connected to the connecting portion 112. Therefore, the headband 120 can be applied to different hosts 110 according to needs, and different headbands can be used to match the original host, so that the head-mounted device 100 can be applied to a variety of different usage scenarios.
[0022] Figure 4 yes Figure 1 Schematic diagram of the disassembled state of the connection between the main body and the headband of the head-mounted device. Figure 5 yes Figure 1 Schematic diagram of the connection end of the headband of the headset. Figure 4 and Figure 5 A first buckle portion 122B1 of each connecting end 122 can rotatably buckle a second buckle portion 112A of the corresponding connecting portion 112 . Figure 3C In the embodiment, when the headband 120 rotates relative to the host 110 to a detachable position, the first buckle portion 122B1 is separated from the second buckle portion 112A, so that the connecting end 122 can be detached from the connecting portion 112 .
[0023] As can be seen from the above, the headband 120 of the head-mounted device 100 of this embodiment is not only rotatable, but also can be detached from the host 110 when the headband 120 is rotated relative to the host 110 to a detachable position. Therefore, each user can rotate the headband 120 according to their own preferences so that the headband 120 contacts the position that they feel most comfortable. Moreover, as long as the headband 120 is rotated to a detachable position, the headband 120 can be directly detached without additional operations. The headband 120 can further have a back of the head pad 126 for contacting the back of the user's head to provide support and increase the comfort of wearing.
[0024] Please refer to Figure 4 and Figure 5 In this embodiment, each connecting end 122 includes a housing 122A, a first fastener 122B and a rotating disk 122C. The first fastener 122B is disposed in the housing 122A. The first fastener 122B is used to move relative to the housing 122A in an axial direction A10. Figure 5 In the embodiment, the first locking portion 122B1 of the first locking member 122B is retracted into the housing 122A. Figure 5 The connection terminal 122 of the state can be placed Figure 4At this time, the first buckle portion 122B1 is retracted into the housing 122A, so it will not interfere with the second buckle portion 112A of the connecting portion 112, and the two are separated.
[0025] On the other hand, the first buckle portion 122B1 of the first buckle member 122B may also protrude from the housing 122A. At this time, if the connecting end 122 has been inserted into the connecting portion 112, the first buckle portion 122B1 protruding from the housing 122A will buckle the corresponding second buckle portion 112A of the connecting portion 112, so that the connecting end 122 is connected to the connecting portion 112 and cannot be separated.
[0026] The rotating disk 122C is rotatably connected to the first latch 122B. For example, the rotating shaft 122C4 of the rotating disk 122C can be inserted into the shaft hole 122B3 of the first latch 122B, but the rotating disk 122C and the first latch 122B can also be rotatably connected to each other using other mechanisms. The first latch 122B is used to move relative to the rotating disk 122C in the axial direction A10. That is, the first latch 122B can move away from or approach the rotating disk 122C in the axial direction A10, and the cooperation between the rotating shaft 122C4 and the shaft hole 122B3 makes the movement of the first latch 122B limited in the axial direction A10. A third latch portion 122C1 of the rotating disk 122C is used to latch a fourth latch portion 112B of the corresponding connecting portion 112. Therefore, when the connecting end 122 has been inserted into the connecting portion 112 , the fourth locking portion 112B prevents the rotating disk 122C from rotating relative to the connecting portion 112 , but the rotating disk 122C can rotate relative to other components of the connecting end 122 .
[0027] Fig. 6A and Figure 6B yes Figure 1 Schematic diagram of two states of the buckle at the connecting end of the headband of the head-mounted device and the turntable. Fig. 7A and Figure 7B They are Figure 1 The connection end of the headband of the head mounted device corresponds to Fig. 6A and Figure 6B Please refer to the schematic diagram of the two states. Figure 3A , Fig. 6A and Fig. 7A In this embodiment, the surface of the rotating disk 122C facing the first locking member 122B has an arc-shaped groove 122C2. The surface of the first locking member 122B facing the rotating disk 122C has an arc-shaped convex rib 122B2. Figure 3A When the headband 120 is away from the detachable position relative to the host 110, the arc-shaped rib 122B2 keeps the turntable 122C away from the first buckle 122B, and the first buckle portion 122B1 protrudes from the housing 122A, that is, Fig. 6A and Fig. 7A Specifically, Fig. 6A and Fig. 7A In the state, because the position of the arc rib 122B2 does not completely correspond to the arc groove 122C2, the arc rib 122B2 cannot be placed in the arc groove 122C2, and a distance will be generated between the rotating disk 122C and the first locking member 122B to accommodate the arc rib 122B2. In other words, the first locking portion 122B1 of the first locking member 122B will also protrude upward, and at this time, the first locking portion 122B1 protrudes from the housing 122A and can lock the second locking portion 112A.
[0028] Please refer to Figure 3C , Figure 6B and Figure 7B , Figure 3C When the headband 120 rotates relative to the host 110 to the detachable position, the arcuate rib 122B2 slides into the arcuate groove 122C2, and the first buckle portion 122B1 retracts into the housing 122A, that is, Figure 6B and Figure 7B Specifically, Figure 6B and Figure 7B In the state, because the position of the arc-shaped convex rib 122B2 completely corresponds to the arc-shaped groove 122C2, the arc-shaped convex rib 122B2 is placed in the arc-shaped groove 122C2, and the rotating disk 122C can completely fit the first buckle 122B. In other words, the first buckle portion 122B1 of the first buckle 122B will also retract downward, and at this time, the first buckle portion 122B1 is retracted into the housing 122A and separated from the second buckle portion 112A, so the connecting end 122 can be detached from the connecting portion 112.
[0029] Figure 8 yes Figure 1 A diagram of the head mounted device's connection section. Figure 3C , Figure 6B and Figure 8 At this time, although the positions of the arc groove 122C2 of the rotating disk 122C and the arc convex rib 122B2 of the first locking member 122B correspond to each other, an external force still needs to be applied to the first locking member 122B to make it lean against the rotating disk 122C. In the process of detaching the connecting end 122 from the connecting portion 112, the inclined surface 112D adjacent to the second locking portion 112A will apply a thrust to the first locking portion 122B1. Since the arc convex rib 122B2 can be placed in the arc groove 122C2, the arc convex rib 122B2 will not hinder the first locking member 122B from leaning against the rotating disk 122C, and the connecting end 122 can also be smoothly detached from the connecting portion 112.
[0030] In this embodiment, the height of the arc-shaped rib 122B2 is designed to gradually increase from both ends to the middle, and the depth of the arc-shaped groove 122C2 is correspondingly designed to gradually deepen from both ends to the middle. Therefore, when the rotating disk 122C and the first fastener 122B rotate relative to each other, the distance between the rotating disk 122C and the first fastener 122B gradually increases or decreases to avoid the feeling of jamming. Of course, the height of the arc-shaped rib 122B2 and the depth of the arc-shaped groove 122C2 can also be designed in other ways to obtain the desired operating experience.
[0031] Please refer to Figure 4 and Figure 5 In this embodiment, each connection end 122 may further include a second snap-fitting member 122D. The second snap-fitting member 122D is disposed in the housing 122A. The second snap-fitting member 122D is used to move relative to the housing 122A in the axial direction A10. A fifth snap-fitting portion 122D1 of the second snap-fitting member 122D is used to protrude from the housing 122A and snap-fit a sixth snap-fitting portion 112C of the corresponding connection portion 112. The fifth snap-fitting portion 122D1 of the second snap-fitting member 122D is also used to retract into the housing 122A and separate from the sixth snap-fitting portion 112C. The rotating disk 122C is rotatably connected to the second snap-fitting member 122D and is located between the first snap-fitting member 122B and the second snap-fitting member 122D. When the rotating disk 122C rotates relative to the connection end 122, the first snap-fitting member 122B and the second snap-fitting member 122D move in opposite directions relative to the rotating disk 122C in the axial direction A10. That is, the second locking member 122D is substantially the same as the first locking member 122B, and the two are symmetrical to each other with the rotating disk 122C as the center.
[0032] When the headband 120 is rotated from the detachable position to another position relative to the host 110, the first buckle 122B and the second buckle 122D gradually move away from the turntable 122C, and the first buckle portion 122B1 and the fifth buckle portion 122D1 gradually protrude from the housing 122A, and buckle the second buckle portion 112A and the sixth buckle portion 112C, so that the headband 120 is firmly connected to the host 110 and will not be separated from the host 110.
[0033] When the headband 120 is rotated from other positions to a detachable position relative to the host 110, the first buckle 122B and the second buckle 122D gradually approach the turntable 122C, and the first buckle portion 122B1 and the fifth buckle portion 122D1 gradually retract into the housing 122A and disengage from the second buckle portion 112A and the sixth buckle portion 112C, so that the headband 120 can be detached from the host 110.
[0034] In addition, the surface of the rotating disk 122C facing the second buckle 122D has an arc-shaped groove 122C2. The surface of the second buckle 122D facing the rotating disk 122C has an arc-shaped convex rib 122D2. When the headband 120 rotates to a detachable position relative to the host 110, the arc-shaped convex rib 122D2 slides into the arc-shaped groove 122C2, and the first buckle portion 122D1 of the second buckle 122D retracts into the housing 122A. When the headband 120 leaves the detachable position relative to the host 110, the arc-shaped convex rib 122D2 keeps the rotating disk 122C and the second buckle 122D at a distance, and the first buckle portion 122D1 protrudes from the housing 122A.
[0035] In this embodiment, the turntable 122C has a convex point 122C3, and the corresponding housing 122A has a limiting portion 122A21. The cooperation between the convex point 122C and the limiting portion 122A21 is used to limit the rotation angle of the turntable 122C relative to the connection end 122. For example, the limiting portion 122A21 includes two bearing surfaces corresponding to the circumference of the turntable 122C. When the turntable 122C rotates relative to the housing 122A, the convex point 122C can move between the two bearing surfaces. However, when the convex point 122C contacts the bearing surface of the limiting portion 122A21, the turntable 122C can no longer continue to rotate in the same direction relative to the housing 122A. Therefore, an appropriate supporting force can be provided when a specific angle is formed between the host 110 and the headband 120.
[0036] In this embodiment, the housing 122A is, for example, divided into a first housing 122A1 and a second housing 122A2 to facilitate assembly. The turntable 122C is disposed between the first housing 122A1 and the second housing 122A2, the first latch 122B is disposed between the first housing 122A1 and the turntable 122C, and the second latch 122D is disposed between the second housing 122A2 and the turntable 122C. The first housing 122A1, for example, has a positioning pin 122A11 and an opening 122A12. The first latch 122B, for example, has a positioning hole 122B4 for inserting the positioning pin 122A11 so that the first latch 122B cannot rotate relative to the first housing 122A1. The first latch portion 122B1 is adapted to pass through the opening 122A12 and protrude outside the first housing 122A1. The second housing 122A2, for example, has a positioning pin 122A22 and an opening 122A23. The second locking member 122D has, for example, a positioning hole 122D4 for the positioning pin 122A22 to be inserted into, so that the second locking member 122D cannot rotate relative to the second housing 122A2. The fifth locking portion 122D1 is adapted to pass through the opening 122A23 and protrude out of the second housing 122A2.
[0037] The host 110 of the present embodiment is a head-mounted display, which can be applied to, for example, a virtual reality system, an augmented reality system, or a mixed reality system. The host 110 may include components such as an optical system and a protective housing, and may be provided with a display or be suitable for placing a display. The aforementioned display may be a built-in display or an external portable display (such as a smart phone, etc.), but the present invention is not limited thereto. The optical system includes optical components for changing the optical path of the display, such as a lens, a light guide, or a prism. Figure 1 The host 110 in the figure is presented in a slightly larger form, but the host 110 may also be a lighter form or other forms.
[0038] In summary, in the head-mounted device and the headband of the present invention, the headband can rotate relative to the host, which is suitable for the user to adjust the position of the headband according to his or her own preferences. In addition, because the headband can be detached from the host, the user can replace the headband or replace the host according to the usage scenario.
