[0036] The head-mounted XR device generally comprises an XR host for imaging and a band for wearing the XR host on the head. However, the band in the prior art is generally integrally arranged with the XR host, and in order to provide support strength and structural strength, the band is generally a hard shell, which causes the head-mounted XR device to be unable to be stored separately, occupy a large space, and be easily damaged by external force due to the hard material of the band. In addition, the increasing requirement of users for comfort leads to different needs of users for the band in different scenarios, but the integrally arranged band cannot be replaced and cannot meet the different needs of users for the band.

[0037] To solve the above problems, the present application provides a head-mounted XR device 100.

[0038] Please refer to Figure 1 , Figure 4 and Figure 6 In an embodiment of the present application, the head-mounted XR device 100 comprises an XR host 1 and a band assembly 2. The XR host 1 forms an imaging surface 11 and a wearing surface 12 on both sides in a first direction, respectively. The XR host 1 is provided with a mounting rod 13 on the edge of both sides in a second direction. The mounting rod 13 extends in the direction of the wearing surface 12 along the first direction. The first direction is different from the second direction. Each mounting rod 13 is provided with a clamping groove 14 on the side facing the other mounting rod 13. The clamping groove 14 comprises a guide section 141 and a clamping section 142 which are sequentially communicated along the first direction. The band assembly 2 is provided with two buckles 21 on opposite sides in the second direction, respectively. The two buckles 21 are arranged corresponding to the two clamping grooves 14, respectively. The buckle 21 is configured to extend into the corresponding guide section 141 along the second direction, and to slide from the guide section 141 into the clamping section 142 along the first direction to be clamped and matched with the clamping section 142.

[0039] It should be noted that the specific structure and function of the band assembly 2 are not limited, and different band assemblies 2 can be designed according to different use scenarios and use requirements. However, the buckle 21 needs to be installed on the band assembly 2, and the buckle 21 can extend into the clamping groove 14.

[0040] The technical scheme of the present application adopts the above technical scheme, sets the mounting rod 13 on the two side edges of the XR host 1 along the second direction, sets the clamping groove 14 on the side of each mounting rod 13 facing the other mounting rod 13, sets the buckle 21 on the two sides of the binding strap assembly 2 corresponding to the clamping groove 14 along the second direction, and sets the binding strap assembly 2 separately from the XR host 1. When in use, the binding strap assembly 2 is moved to the position corresponding to the mounting rod 13, the clamping block is inserted into the clamping groove 14, first contacts the guide section 141, is in sliding contact with the guide section 141, is guided by the guide section 141, and is then slid to the clamping section 142. Then, the buckle 21 is clamped and matched with the clamping section 142, and the fixing of the binding strap assembly 2 and the XR host 1 is completed. The design of the buckle 21 and the clamping groove 14 makes the binding strap assembly 2 easily installed and disassembled with the XR host 1, so that the binding strap assembly 2 and the XR host 1 can be separately set and stored, occupy smaller space, and the binding strap assembly 2 set separately is less likely to be damaged by force, prolongs the service life of the binding strap assembly 2, and different binding strap assemblies 2 can be replaced according to different needs. Only the buckle 21 and the clamping section 142 of one kind of binding strap assembly 2 need to be disassembled, and then the buckle 21 and the clamping section 142 of another kind of binding strap assembly 2 are clamped and matched, so that the replacement and installation of the binding strap assembly 2 are completed. The head-mounted XR device 100 can replace different binding strap assemblies 2 according to different use scenarios, and meet the use needs of different users.

[0041] Please refer to Figure 7 and Figure 8 Further, the buckle 21 comprises a connecting block 211 and a clamping block 212, the clamping block 212 is connected to the binding strap assembly 2 through the connecting block 211, a limiting gap 213 is formed between the clamping block 212 and the binding strap assembly 2, a limiting wall 143 is formed on the side groove wall of the clamping groove 14 away from the mounting rod 13 along the second direction, and the limiting wall 143 is used for extending into the limiting gap 213 and being in sliding contact with the connecting hole when the buckle 21 slides from the guide section 141 to the clamping section 142. The area of the clamping block 212 is greater than the area of the connecting block 211, so that the clamping block 212 covers the connecting block 211, and there is a protruding part outside the periphery of the clamping block 212. The protruding part and the binding strap assembly 2 form the limiting gap 213, the limiting wall 143 extends into the limiting gap 213 when the buckle 21 slides to the clamping section 142, and at this time, the opposite two surfaces of the limiting wall 143 are respectively in abutment with the surface of the clamping block 212 facing the binding strap assembly 2 and the surface of the binding strap assembly 2 facing the clamping block 212, that is, the protruding part outside the periphery of the clamping block 212 is blocked by the limiting wall 143, so as to limit the binding strap assembly 2 and fix the binding strap assembly 2 on the XR host 1. Through the above structure, the binding strap assembly 2 can provide vertical supporting force and horizontal limiting force for the XR host 1, so as to support the XR host 1 and prevent the binding strap assembly 2 from being separated from the XR host 1.

[0042] Please refer toFigures 7 to 10 In an embodiment, the limiting wall 143 is provided with a through hole 144 communicated with the clamping groove 14, the through hole 144 extends along the first direction, and the through hole 144 is formed with an opening 145 communicated with the guide portion at one side of the guide portion, the buckle 21 can slide from the guide segment 141 to the through hole 144 along the first direction through the opening 145, and the hole wall of the through hole 144 is used for sliding contact with the connecting block 211.

[0043] Specifically, the limiting wall 143 is a U-shaped wall, the two ends of the limiting wall 143 along the first direction are respectively an open end 146 and a closed end 147, the open end 146 forms the opening 145, the limiting wall 143 surrounds the U-shaped through hole 144, the hole walls on both sides of the through hole 144 corresponding to the open end 146 are respectively provided with two guide slopes 148, and the distance between the two guide slopes 148 is tapered away from the guide portion. It can be understood that the open end 146 of the U-shaped wall includes two end portions arranged at intervals, the two end portions are respectively provided with two guide slopes 148, and the distance between the two guide slopes 148 is tapered away from the guide portion, so that the distance between the guide slopes 148 is smaller when closer to the through hole 144, the guide slopes 148 are in sliding contact with the connecting block 211 to guide the connecting block 211, so that the connecting block 211 can more easily drive the clamping block 212 to be clamped into the clamping segment 142, the cooperation process of the buckle 21 and the clamping groove 14 is simplified, and the assembly and disassembly efficiency is improved.

[0044] In an embodiment, the side slot wall of the card slot 14 close to the mounting rod 13 is formed with an arc-shaped wall 149 in the second direction, which is spaced apart from the limiting wall 143 in the second direction and is arranged opposite to the limiting wall 143, and the arc-shaped wall 149 is arranged to be away from the limiting wall 143. One side of the clamping block 212 away from the connecting block 211 is formed with an arc-shaped sliding surface 214 matched with and slidingly fitted with the arc-shaped wall 149. The distance between the arc-shaped wall 149 and the outer side wall of the connecting rod away from the card slot 14 gradually decreases in a direction away from the XR host 1, that is, the card slot 14 gradually penetrates into the mounting rod 13. The arc-shaped wall 149 arranged obliquely makes the distance between the limiting wall 143 and the arc-shaped wall 149 at a position close to the end of the connecting rod larger, so as to allow the clamping block 212 to extend into the card slot 14, and the sliding surface of the clamping block 212 is in sliding contact with the arc-shaped wall 149, so that the clamping block 212 is directly clamped into the clamping section 142 under the guidance of the arc-shaped wall 149 after abutting against the arc-shaped wall 149, thereby avoiding the buckle 21 from being pulled out of the card slot 14 before the clamping block 212 is clamped with the clamping section 142, and ensuring that the buckle 21 can be smoothly and accurately inserted into the card slot 14, so as to reduce the deviation or jamming in the insertion process.
