[0037] Specifically, the second locking member is a buckle type locking member, which comprises a second buckle 51 and a second buckle slot 52, the side wall of the bottom enclosing ring 12 is provided with the second buckle 51, and the side wall of the top enclosing ring 22 is provided with the second buckle slot 52 corresponding to the position of the second buckle 51, when the bottom shell 1 and the cover shell 2 are installed, the top enclosing ring 22 is embedded on the inner side of the bottom enclosing ring 12 and is clamped by the second buckle 51 and the second buckle slot 52 to complete the installation and locking of the bottom shell 1 and the cover shell 2, as a subsequent improved embodiment, the bottom shell 1 and the cover shell 2 are further provided with threaded holes, and the bottom shell 1 and the cover shell 2 can be further locked and fixed by screws.

[0038] Specifically, due to the differences in the weights of different VR hosts, the configurations of different VR headbands will also be different, and here, when the above different combinations are put together, the front and rear weight of the head will change, so the user needs to select different weight blocks 102 according to the VR host used and the VR headband selected, when different sizes and weights of the weight block 102 are installed in the weight compartment 101, due to the difference in size, the weight block 102 of different models cannot be matched with the weight compartment 101 with the same volume, here, a solution is proposed, the inner side of the weight compartment 101 is provided with an elastic buffer 6, the elastic buffer 6 comprises a buffer spring 61 and an elastic protrusion 62, the inner side of the weight compartment 101 is provided with the buffer spring 61, the free end face of the buffer spring 61 is inwardly provided with the elastic protrusion 62, preferably, the buffer spring 61 is formed by a U-shaped hollow at the bottom wall of the seat 13, of course, it can also be made in the form of a direct spring, the buffer spring 61 has elasticity because it is only connected to the bottom wall of the seat 13 at one place, the elastic protrusion 62 is arranged towards the opening of the weight compartment 101 or the direction of the weight block 102, when the weight block 102 is placed inwardly into the weight compartment 101, it will press the protrusion inwardly, the protrusion will drive the buffer spring 61 to press inwardly, and finally cooperate with the locking and pressing of the outer weight compartment cover 33 to complete the stable installation of the weight block 102, and can adapt to different models and sizes of the weight block 102, so as to meet the needs of adjusting the weight and size of the weight block 102.

[0039] Specifically, in order to realize flexible matching of the weight block 102, here, the weight compartment 101 is composed of a plurality of sub-ware bodies 101a, which are distributed in the curvature of the fitting surface 103 of the weight box 10, for example, if the fitting surface 103 is designed as a concave surface, the surface composed of the plurality of sub-ware bodies 101a after being connected is also a concave surface, if the fitting surface 103 is designed as a V-shaped corner surface, the surface composed of the plurality of sub-ware bodies 101a after being connected is also a corner surface, as one of the embodiments, the plurality of sub-ware bodies 101a are arranged in a transverse direction and a longitudinal direction, for example, Figure 8The two sub-warehouses 101a are horizontally arranged, and one of the two sub-warehouses 101a can be selected to accommodate the counterweight 102 when the counterweight 102 is placed. Different weight models of the counterweight 102 can also be used as counterweights according to the weight of the front-end VR device. Thus, the user can select the counterweight 102 for installation according to the optimal counterweight matching prepared in advance by the product. As an alternative embodiment, the plurality of sub-warehouses 101a are circumferentially distributed (not shown in the figure). In this embodiment, the counterweight warehouse cover 33 is shaped and arranged in a circular or elliptical shape. The sub-warehouses 101a are circumferentially distributed, which has the advantage of dispersing the counterweight 102 into smaller units, which can be placed and taken away symmetrically. This adjustment of the counterweight 102 has less effect on the overall weight of the rear pillow assembly 710 and the entire VR headband 700, and can achieve symmetric placement and removal.

[0040] Specifically, in order to facilitate the installation of the counterweight warehouse cover 33, one side of the warehouse seat 13 is provided with an entry slot 132, and the hinge hole 131 is an open hinge hole 131 located on one side of the entry slot 132. During use, the side of the counterweight compartment cover with the hand-pulling tab 41 can be inserted along the entry slot 132. When the hand-pulling tab 41 reaches above the lock slot 42, the hinge shaft 31 reaches the position of the hinge hole 131. Thus, the installation of the counterweight warehouse cover 33 can be completed by clamping the hinge shaft 31 to the position of the hinge hole 131. This installation method can greatly avoid the problem of inconvenience to other components caused by the excessive opening angle of the counterweight warehouse cover 33. Thus, this installation method does not need to consider the opening angle of the counterweight warehouse cover 33, because the installation is from the entry slot 132 on the side of the warehouse seat 13.

[0041] The utility model discloses still disclose a kind of VR headband 700 installed with counterweight assembly 100, including rear pillow assembly 710 and side band 730, wherein the side of rear pillow assembly 710 is connected with side band 730, the upper mounting of rear pillow assembly 710 is described above described counterweight assembly 100, interface above described, counterweight assembly 100 and the mounting of rear pillow assembly 710 have multiple installation modes, such as magic paste adhering mode, or using clamping mode, preferably clamping mode here, specifically, rear pillow assembly 710 includes rear pillow support 711 and rear pillow cotton 712, the upper end of rear pillow support 711 is hollow and forms hollow groove 711a, when installing, bottom shell 1 is inserted from the bottom of hollow groove 711a upwards, bottom enclosing ring 12 is inserted into hollow groove 711a, because the size of panel 11 is greater than the size of hollow groove 711a, so panel 11 remains at the bottom, that is, bottom clamping portion 111 remains at the bottom, cover shell 2 is inserted from the upper end of hollow groove 711a downwards, and the diameter of top enclosing ring 22 is less than the diameter of bottom enclosing ring 12, and top enclosing ring 22 is just inserted into the inner side of bottom enclosing ring 12 and is clamped and matched by second buckle 51 and second clamping groove 52, and because the size of face cover 21 is greater than the size of hollow groove 711a, that is, top clamping portion 211 remains at the top of hollow groove 711a, whereby top clamping portion 211 and bottom clamping portion 111 respectively clamp the groove wall of the edge of hollow groove 711a from two directions of top and bottom, so as to clamp rear pillow support 711, bottom shell 1 and cover shell 2 just form a complete counterweight box 10, and the bottom of counterweight box 10 has a fitting surface 103, which is just located at the inner side end face of rear pillow support 711 at this time, that is, towards the back of the head of human body position, but in order to make wearing more comfortable, the inner side of rear pillow support 711 is provided with rear pillow cotton 712, and rear pillow cotton 712 is preferably connected with rear pillow support 711 in the form of magic paste, after installing counterweight assembly 100, rear pillow cotton 712 is pasted again by magic paste form, when needing to replace counterweight block 102, tear rear pillow cotton 712, then open counterweight bin cover 33, remove original counterweight block 102, replace new counterweight block 102, or adjust the weight combination form of counterweight block 102, after operation is completed, cover counterweight bin cover 33 again, and finally paste rear pillow cotton 712.

[0042] The above embodiments are only preferred embodiments of the utility model, and cannot be used to limit the range of protection of the utility model, and any non-substantial changes and replacements made by the person skilled in the art on the basis of the utility model belong to the range of protection required by the utility model.
