[0033] Reference Figure 1-5 As shown: A portable headband device includes a headrest 01 and a connecting and adjusting structure. The headrest 01 is used to wrap around the back of the user's head; the connecting and adjusting structure is used to connect the headrest 01 and the XR host to wear the XR host on the user's head.

[0034] The headrest 01 is arc-shaped, and the connection adjustment structure includes a pair of side adjustment straps 02 and a pair of connection covers 03. The pair of side adjustment straps 02 are located on the left and right sides of the user's head, respectively. One end of the side adjustment strap 02 is fixed to the headrest 01, and the other end of the side adjustment strap 02 is connected to one of the connection covers 03. The connection cover 03 is used for detachable connection with the connection ear of the XR host.

[0035] In order to securely connect the side adjustment strap 02 to the headrest 01, the headrest 01 is also provided with an installation port 043. There is a pair of installation ports 043, located on the left and right sides of the headrest 01 respectively. One end of the side adjustment strap 02 is inserted into the installation port 043 and adhered and fixed to the headrest 01.

[0036] The connecting cover 03 has a first strap opening 041 and a second strap opening 042. One end of the side adjustment strap 02 passes through the first strap opening 041 and the second strap opening 042 and extends to the side of the connecting cover 03 away from the XR host. The connection adjustment structure also includes a fixing component, which is used to fix the position of the end of the side adjustment strap 02 that passes through the first strap opening 041 and the second strap opening 042.

[0037] In use, install the connector cover 03 onto the connector ear of the XR host, then loosen the side adjustment strap 02 and place the XR host on the user's face. Then place the headrest 01 on the back of the user's head. Finally, tighten the side adjustment strap 02 and fix one end of the side adjustment strap 02 with the firmware component to stably fix the XR host on the user's face.

[0038] The connecting cover 03 includes a cover plate 031 and a clamping frame 032. The clamping frame 032 is arranged around the periphery of the cover plate 031 and is used to clamp the connecting ears of the XR host. The first strap opening 041 is located on the connecting cover 03 near the headrest 01 and is formed at the clamping frame 032. In this embodiment, the first strap opening 041 is located on the clamping frame 032 near the headrest 01. The second strap opening 042 is located at the cover plate 031. The side adjustment strap passes through the first strap opening 041 and the second strap opening 042 in sequence and extends to the side of the connecting cover 03 away from the user's head.

[0039] To reduce friction between the side adjustment belt 02 and the cover plate 031 and connecting ears, facilitating adjustment of the side adjustment belt 02, the cover plate 031 has a recessed groove 044 on the side closest to the XR main unit. The recessed groove 044 extends from the end of the cover plate 031 near the headrest 01 to the second belt opening 042. Furthermore, the second belt opening 042 is positioned perpendicular to the length of the connecting cover 03. This ensures that the side adjustment belt 02 experiences uniform stress during operation at the location of the second belt opening 042, improves the service life of the side adjustment belt 02, and also makes it easier for the user to pull the side adjustment belt 02.

[0040] The second opening 042 has a relief slope 0421 on the side wall near the settling tank 044. The angle between the relief slope 0421 and the outer side of the cover plate 031 is greater than 10 degrees and less than 90 degrees. In this embodiment, the relief slope 0421 and the outer side of the cover plate 031 are set at a 45-degree angle.

[0041] To facilitate the disassembly of the connector cover 03 from the XR host's connecting ear, the locking frame 032 is equipped with a lever protrusion 06. During disassembly, the lever protrusion 06 can be used as a point of leverage, thereby facilitating the quick separation of the connector cover 03 from the connecting ear.

[0042] The fixing component includes a hook surface portion 053 disposed at the end of the side adjustment belt 02 and a rough surface portion disposed at the main body portion of the side adjustment belt 02. After the side adjustment belt 02 passes through the first belt opening 041 and the second belt opening 042, the hook surface portion 053 at the end of the side adjustment belt 02 is adjusted to adhere to each other with the rough surface portion at the main body portion of the side adjustment belt 02, thereby realizing the tightening and loosening of the headband device.

[0043] To further improve the stability and applicability of the headband device, a textured surface portion 051 is fixed to the side of the connecting cover 03 opposite to the XR main unit. This arrangement allows the side adjustment strap 02 to adhere to the textured surface portion 051 immediately after passing through the first strap opening 041 and the second strap opening 042.

[0044] The side adjustment band 02 is an elastic band, and the looped part 052 is a hook and loop fastener strip, which is fixed to the side of the elastic band away from the user's head. The hook part 053 is a hook and loop fastener strip, and both the looped and hook and loop fastener strips are non-elastic.

[0045] As can be seen from the above description, the beneficial effects of this utility model are: the simple headband device can achieve stable wearing on the one hand, and can also significantly reduce the overall weight of the headband device and improve wearing comfort on the other hand.

[0046] In use, first fasten the connector cover 03 to the connector ear of the XR host to fix the connector cover 03 to the connector ear. Separate the hook side 053 of the side adjustment strap 02 from its fur side 052 and the fur side 051. Then place the XR host on the user's face and place the headrest 01 on the back of the user's head, so that the user's head is between the pair of side adjustment straps 02. Finally, adjust the position of the end of the side adjustment strap 02 to adjust the tightness of the fit. When the user feels comfortable, fasten the hook side 053 of the side adjustment strap 02 to the fur side 051 and the fur side 052 respectively to achieve a stable fit of the XR host.

[0047] It will be readily understood by those skilled in the art that the above embodiments can be freely combined and superimposed without conflict.

[0048] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
