Because the head circumference of different users may differ, the head-mounted device in the related art usually includes a band limiting mechanism with adjustable size, and a user can adjust the length of the band to adapt to the head circumference of the user. In the related art, the band adjustment principle of the band limiting mechanism of the head-mounted device is similar to the adjustment principle of the watchband of a watch, that is, the band is divided into a first segment that is fixed and not adjustable, and a second segment that is adjustable in length, one end of the first segment is provided with a lock buckle, and the first segment also needs to be connected with a limiting ring, one end of the second segment is sequentially threaded through the locking hole of the lock buckle and the limiting hole of the limiting ring, so that the overlapping length between the first segment and the second segment is changed by moving the second segment towards or away from one side of the first segment, so as to adjust the overall length of the band. However, in this kind of band limiting mechanism, the limiting ring usually needs to be fixedly connected with the first segment by the process of adhesion through the outermost cloth strip, and this connection mode directly exposes the connection cloth strip and the adhesion process to the outermost side, resulting in the problem of poor appearance.

It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are generally of a kind and do not limit the number of objects, for example, the first object can be one or more.

[0018] The band limiting assembly 100 and the head-mounted device provided by the embodiments of the present application will be described in detail below in combination with the drawings, through specific embodiments and application scenarios.

[0019] Please refer to Figures 1 to 5 The band limiting assembly 100 provided by the embodiments of the present application is applied to a head-mounted device, and includes a lock buckle 110, a connecting piece 120, a limiting piece 130, and a first flexible band 140. The lock buckle 110 is provided with a strip-shaped hole 111. The limiting piece 130 includes a first limiting hole 131, a second limiting hole 132, and a separation part 133. The first limiting hole 131, the separation part 133, and the second limiting hole 132 are sequentially stacked in the thickness direction of the first flexible band 140.

[0020] The first end 121 of the connecting piece 120 is fixedly connected with the separation part 133, and the second end 122 of the connecting piece 120 is fixedly connected with one end of the lock buckle 110 facing the limiting piece 130.

[0021] The first flexible band 140 is sequentially arranged in the first limiting hole 131, the strip-shaped hole 111, and the second limiting hole 132. The adjusting end 143 of the first flexible band 140 is located on the side of the second limiting hole 132 away from the lock buckle 110. The first flexible band 140 includes a first segment 141 between the first limiting hole 131 and the strip-shaped hole 111, and a second segment 142 between the second limiting hole 132 and the strip-shaped hole 111. The first segment 141, the connecting piece 120, and the second segment 142 are sequentially stacked.

[0022] The above-mentioned head-mounted device can be various types of virtual reality devices. Accordingly, please refer to Figure 7 The above-mentioned band limiting assembly 100 can be a length-adjustable band structure for connecting two temples of a virtual reality device. Since the length of the band structure is adjustable, it can be suitable for users with different head circumferences.

[0023] Please refer to Figure 5 The length direction of the first limiting hole 131, the length direction of the strip-shaped hole 111 and the length direction of the second limiting hole 132 can be respectively the same as the width direction of the first flexible band 140. The length of the first limiting hole 131, the length of the strip-shaped hole 111 and the length of the second limiting hole 132 can be respectively equal to the width of the first flexible band 140. Thus, when the first flexible band 140 is arranged in the first limiting hole 131, the strip-shaped hole 111 and the second limiting hole 132, the first limiting hole 131, the strip-shaped hole 111 and the second limiting hole 132 can limit the width direction of the first flexible band 140 respectively, so as to ensure that the first flexible band 140 can only slide relative to the first limiting hole 131, the strip-shaped hole 111 and the second limiting hole 132 along the length direction, so as to realize the length adjustment process of the band in the band limiting assembly 100.

[0024] Please refer to Figure 2 The second end 122 of the connecting piece 120 can be fixedly connected with one end of the lock buckle 110 which faces the limiting piece 130.

[0025] The lock buckle 110 can be a back-shaped buckle, or other types of lock buckles 110. The lock buckle 110 can be a rigid material, which is used to realize the closed loop structure of the band sliding adjustment.

[0026] The connecting piece 120 can be made of flexible or rigid material. The first end 121 of the connecting piece 120 can be connected with the separation part 133 by common fixing connection methods such as sewing, bonding, buckling or injection molding. Correspondingly, the second end 122 of the connecting piece 120 can be fixedly connected with the lock buckle 110 by common fixing connection methods such as sewing, bonding, buckling or injection molding.

[0027] The limiting piece 130 can be spliced by two ring structures, and the spliced part of the two ring structures forms the blocking part. In addition, the limiting piece 130 can also be provided with a blocking piece in the middle of a ring structure, which divides the ring-shaped hole in the ring structure into the first limiting hole 131 and the second limiting hole 132, and the blocking piece forms the blocking part.

[0028] Please refer to Figure 3The strap limiting component 100 further includes a second flexible strap 150 with a non-adjustable length. The overall length of the strap in the strap limiting component 100 is the sum of the length of the second flexible strap 150 and the length of the inner layer of the first flexible strap 140. When it is necessary to increase the overall length of the strap in the strap limiting component 100, the outermost end of the first flexible strap 140 can be pushed to the left. At this time, the inner layer of the first flexible strap 140 moves to the right, thereby achieving bidirectional adjustment. During this process, the length of the outer layer of the first flexible strap 140 decreases, and the length of the inner layer of the first flexible strap 140 increases, thereby increasing the overall length of the strap in the strap limiting component 100. Correspondingly, when it is necessary to decrease the overall length of the strap in the strap limiting component 100, the outermost end of the first flexible strap 140 can be pulled to the right, that is, the adjusting end 143 of the first flexible strap 140 is pulled along... Figure 1 As shown by the dotted line, the inner layer of the first flexible strap 140 moves to the left, thereby achieving bidirectional adjustment. During this process, the outer layer length of the first flexible strap 140 increases, and the inner layer length of the first flexible strap 140 decreases, thereby reducing the overall length of the strap in the strap limiting assembly 100.

[0029] In this embodiment, since the limiting member 130 is connected to the latch 110 through the connector 120, and the first segment 141, the connector 120 and the second segment 142 are stacked in sequence, the connector 120 can be hidden between the first segment 141 and the second segment 142. This improves the aesthetics of the connection between the limiting member 130 and the latch 110. Furthermore, since the first flexible strap 140 is sequentially inserted into the first limiting hole 131, the strip hole 111, and the second limiting hole 132, and the adjustment end 143 of the first flexible strap 140 is located on the side of the second limiting hole 132 away from the buckle 110, the first flexible strap 140 is folded at the strip hole 111 to form a double-layer structure. Since the first flexible strap 140 is a double-layer structure, compared with a single-layer structure, the first flexible strap 140 can be stacked in the thickness direction, which is beneficial to increasing the length of the first flexible strap 140. Since the first flexible strap 140 serves as the length adjustment part of the strap limiting component 100, the longer the first flexible strap 140 is, the greater the range of strap length adjustment of the strap limiting component 100. That is, the above arrangement is beneficial to increasing the range of strap length adjustment of the strap limiting component 100.

[0030] Optionally, the width of the connector 120 is less than or equal to the width of the first flexible strap 140.

[0031] Please see Figure 1Since the connecting piece 120 is located between the first segment 141 and the second segment 142, and the width dimension of the connecting piece 120 is less than or equal to the width dimension of the first flexible band 140, the connecting piece 120 can be completely hidden between the first segment 141 and the second segment 142, that is, the connecting piece 120 does not protrude out of the first segment 141 and the second segment 142.

[0032] It can be understood that the width dimension of the connecting piece 120 is less than the width dimension of the lock buckle 110.

[0033] In this embodiment, by making the width dimension of the connecting piece 120 less than or equal to the width dimension of the first flexible band 140, the connecting piece 120 can be completely hidden between the first segment 141 and the second segment 142, so that the connecting piece 120 cannot be seen in the direction of both sides of the band limiting assembly 100, which can improve the appearance of the connection between the limiting piece 130 and the lock buckle 110.

[0034] Optionally, the first limiting hole 131 has a dimension along the thickness direction of the first flexible band 140 equal to the thickness dimension of the first flexible band 140, and the second limiting hole 132 has a dimension along the thickness direction of the first flexible band 140 equal to the thickness dimension of the first flexible band 140.

[0035] In this embodiment, since the first limiting hole 131 has a dimension along the thickness direction of the first flexible band 140 equal to the thickness dimension of the first flexible band 140, and the second limiting hole 132 has a dimension along the thickness direction of the first flexible band 140 equal to the thickness dimension of the first flexible band 140, the first flexible band 140 can be prevented from being displaced up and down along the thickness direction, that is, the first flexible band 140 can be prevented from being displaced in the direction of the dashed line in FIG. 10, so that the inner and outer layers of the first flexible band 140 can be more closely attached, enhancing the stability of the band guiding and preventing the problem of bulging of the first flexible band 140 due to the close attachment of the inner and outer layers of the first flexible band 140. In addition, since the displacement of the first flexible band 140 along the thickness direction can be prevented, the first flexible band 140 can only slide in the length direction, and without the interference of the thickness direction displacement, the first flexible band 140 can achieve more accurate displacement. Figure 7 Optionally, the connecting piece 120 is a double-layer structure folded around the separation portion 133, and the first end 121 of the connecting piece 120 is a closed end of the double-layer structure, and the second end 122 of the connecting piece 120 is an unclosed end of the double-layer structure.

[0036]

[0037] ​Please refer to Figure 4 (a), the connecting piece 120 can be a double-layer structure formed by folding in half, and the closed end of the connecting piece 120 refers to the end formed by the folding area of the connecting piece 120. Accordingly, the non-closed end of the connecting piece 120, i.e. the end formed by the area where the two heads of the connecting piece 120 are located.

[0038] Please refer to Figure 4 (b), the barrier portion can be embedded inside the connecting piece 120, and the non-closed end of the connecting piece 120 and the barrier portion can be fixedly connected by common fixing connection methods such as sewing, bonding, buckling, or injection molding.

[0039] Please refer to Figure 4 In the embodiment shown in Figure 4 , the connecting piece 120 is made of flexible cloth material, and the limiting piece 130 is made of cloth material with added rigidity.

[0040] In this embodiment, by making the connecting piece 120 a double-layer structure folded around the separation portion 133, and making the non-closed end of the connecting piece 120 fixedly connected with the barrier portion, this is conducive to improving the reliability of the connection between the connecting piece 120 and the barrier portion, reducing the risk of the connecting portion detaching from the barrier portion, and thus the service life of the whole band limiting assembly 100 can be improved.

[0041] Optionally, the connecting piece 120 and the limiting piece 130 are integrally formed.

[0042] Please refer to Figure 5 In some embodiments of the present application, the connecting piece 120 and the limiting piece 130 can both be made of plastic material, and they can be integrally formed by injection molding, i.e. the barrier portion of the connecting piece 120 and the limiting piece 130 does not need to be connected by other connecting structures.

[0043] During the assembly of the band limiting assembly 100, please refer to Figure 5 (a) to Figure 5 (b), the second end 122 of the connecting piece 120 can be embedded in the first groove 112, and the second end 122 of the connecting piece 120 can be fixedly connected with the lock 110, then, please refer to Figure 5 (b) to Figure 5 (c), the lock 110 can be connected with the second flexible band 150 and the second temple 220, in this way, only the fixed end 144 of the first flexible band 140 needs to be fixedly connected with the first temple 210, and subsequently, the adjusting end 143 of the first flexible band 140 is sequentially threaded through the first limiting hole 131, the strip-shaped hole 111, and the second limiting hole 132, and the assembly process of the band limiting assembly 100 can be completed.

[0044] In this embodiment, the connecting piece 120 is integrally formed with the limiting piece 130, which can improve the connection reliability between the connecting piece 120 and the blocking part, reduce the risk of disconnection between the connecting part and the blocking part, and thus prolong the service life of the binding limiting assembly 100 as a whole.

[0045] Optionally, the size of the connecting piece 120 along the length direction of the first flexible binding band 140 is 5 mm to 15 mm.

[0046] In some embodiments of the present application, the size of the connecting piece 120 along the length direction of the first flexible binding band 140 is 10 mm. In some embodiments of the present application, the size of the connecting piece 120 along the length direction of the first flexible binding band 140 is 11 mm.

[0047] In this embodiment, the size of the connecting piece 120 along the length of the first flexible binding band 140 can be regarded as the distance between the lock buckle 110 and the limiting piece 130. Therefore, by setting the size of the connecting piece 120 along the length direction of the first flexible binding band 140 to be 5 mm to 15 mm, the distance between the lock buckle 110 and the limiting piece 130 can be controlled to be 5 mm to 15 mm. It has been verified through experiments that when the distance between the lock buckle 110 and the limiting piece 130 is controlled to be 5 mm to 15 mm, the performance of the binding limiting assembly 100 is relatively good, that is, the overall performance of the binding limiting assembly 100 can be improved.

[0048] Optionally, the lock buckle 110 is provided with a first groove 112 at one end facing the limiting piece 130, and the second end 122 of the connecting piece 120 is embedded in the first groove 112.

[0049] Please refer to Figure 4 , the first groove 112 can be used as an assembly groove. During the assembly of the binding limiting assembly 100, please refer to Figure 4 (a) to Figure 4 (b), the connecting piece 120 can be first fixedly connected with the blocking part, then please refer to Figure 4 (b) to Figure 4 (c), the second end 122 of the connecting piece 120 can be embedded in the first groove 112, and the second end 122 of the connecting piece 120 can be fixedly connected with the lock buckle 110, and then please refer to Figure 4 (c) to Figure 4(d), the lock 110 can be connected with the second flexible band 150 and the second temple 220, so that only the fixed end 144 of the first flexible band 140 is fixedly connected with the first temple 210, and then the adjusting end 143 of the first flexible band 140 is sequentially threaded through the first limiting hole 131, the strip-shaped hole 111 and the second limiting hole 132, so that the assembly process of the band limiting assembly 100 is completed.

[0050] In this embodiment, the first groove 112 is formed at one end of the lock 110 facing the limiting piece 130, and the second end 122 of the connecting piece 120 is embedded in the first groove 112, so that the reliability of the connection between the connecting piece 120 and the lock 110 is improved due to the limiting effect of the first groove 112. At the same time, the connection area of the connecting piece 120 and the lock 110 is hidden inside the first groove 112, so as to improve the appearance of the connection between the connecting piece 120 and the lock 110.

[0051] Optionally, the band limiting assembly 100 further comprises a second flexible band 150, one end of the second flexible band 150 being fixedly connected with one end of the lock 110 away from the limiting piece 130.

[0052] The second flexible band 150 is a band with a length that cannot be adjusted.

[0053] Please refer to Figure 7 In some embodiments of the present application, the head-mounted device comprises a device body 200, the device body 200 comprising a first temple 210 and a second temple 220, one end of the second flexible band 150 away from the lock 110 being fixedly connected with the first temple 210, the first flexible band 140 further comprising a fixed end 144, the fixed end 144 of the first flexible band 140 being fixedly connected with the second temple 220, at this time, the device body 200, the first flexible band 140 and the second flexible band 150 are sequentially connected to form a ring-shaped structure, so that the user can wear the head-mounted device on the head, as shown in Figure 6 It is a schematic diagram of a user wearing a head-mounted device on the head, Figure 6 The dashed line and the solid line in the figure are schematic diagrams of the lengths of the bands corresponding to users with different head circumferences.

[0054] In some embodiments of the present application, the lock 110 away from the limiting piece 130 is provided with a second groove, one end of the second flexible band 150 can be embedded in the second groove, and the one end of the second flexible band 150 embedded in the second groove can be fixedly connected with the lock 110 by common fixing connection methods such as sewing, bonding, buckling or injection molding.

[0055] In this embodiment, the binding position assembly 100 further comprises a second flexible binding 150, one end of the second flexible binding 150 is fixedly connected with the end of the lock buckle 110 which is opposite to the limiting piece 130. In this way, the two external connection ends of the binding position assembly 100 are respectively one end of the first flexible binding 140 and one end of the second flexible binding 150, so that the binding position assembly 100 can be fixedly connected with the leg of the head-mounted device.

[0056] Optionally, the length of the first flexible binding 140 is greater than the length of the second flexible binding 150.

[0057] Please refer to Figure 3 Since the length of the second flexible binding 150 is not adjustable, the overall length of the binding in the binding position assembly 100 is the sum of the length of the second flexible binding 150 and the length of the inner layer of the first flexible binding 140, and the length of the inner layer of the first flexible binding 140 is adjustable. Therefore, the smaller the length of the second flexible binding 150 in the overall length of the binding in the binding position assembly 100, the longer the length of the inner layer of the first flexible binding 140. The length of the outer layer of the first flexible binding 140 can be set to be equal to the length of the inner layer of the first flexible binding 140, and at this time, the overall length of the first flexible binding 140 can also be longer. The longer the length of the first flexible binding 140, the greater the length adjustment range of the binding of the binding position assembly 100, that is, by making the length of the first flexible binding 140 greater than the length of the second flexible binding 150, it is beneficial to increase the length adjustment range of the binding of the binding position assembly 100.

[0058] In some embodiments of the present application, the length of the first flexible binding 140 can be less than 1 / 4L, and in other embodiments of the present application, the length of the first flexible binding 140 can be less than 1 / 5L. Wherein, the L is: when the adjustment end 143 of the first flexible binding 140 is located at the middle position of the length direction of the inner layer of the first flexible binding 140, the overall length of the binding in the binding position assembly 100.

[0059] In this embodiment, by making the length of the first flexible binding 140 greater than the length of the second flexible binding 150, it is beneficial to increase the length adjustment range of the binding of the binding position assembly 100.

[0060] It should be noted that the binding position assembly 100 provided by the embodiments of the present application has at least the following beneficial effects:

[0061] Since the limiting piece 130 has two limiting holes, the two limiting holes can realize double-track guidance, thereby ensuring that the first flexible binding 140 can move smoothly and without deviation during length adjustment.

[0062] By designing the connecting piece 120 to be hidden between the first segment 141 and the second segment 142, the integrity of the appearance of the strap limiting assembly 100 can be improved.

[0063] When the limiting piece 130 is made of fabric material, the strap can be more integrated.

[0064] During the adjustment process, the inner layer and the outer side of the first flexible strap 140 move bidirectionally, which can improve the convenience of use.

[0065] The strap limiting assembly 100 as a whole adopts a modular design, which can facilitate assembly and maintenance.

[0066] Please refer to Figure 7 The application also provides a head-mounted device, which comprises the strap limiting assembly 100 described in the above embodiments.
