头戴式设备的应用领域广泛，特别是对于头戴式电子设备来说，头戴式设备可以用在虚拟现实(VR)系统、增强现实(AR)系统中。无论是对虚拟现实(VR)系统还是增强现实(AR)系统，其前端机构一般为显示装置，通过显示器向用户提供图像、视频等信息，后端机构配合前端机构形成可穿戴式结构。Head-mounted devices have a wide range of applications, especially for head-mounted electronic devices. Head-mounted devices can be used in virtual reality (VR) systems and augmented reality (AR) systems. Whether it is a virtual reality (VR) system or an augmented reality (AR) system, the front-end mechanism is generally a display device, which provides images, videos and other information to users through the display. The back-end mechanism cooperates with the front-end mechanism to form a wearable structure.
现有技术中，后端机构一般为弹性伸缩织物，或者大多数采用的是机械调整机构，调节起来较为繁琐。同时，现有的头戴式设备对于不同人群的适应能力有限，由于小孩、成年人头型和大小不一致，会造成小孩过松，成年人戴起来很紧非常不舒服。而且，即使是成年人，其体型不同，头型大小也不尽相同，因此，现有的头戴式设备适应能力有限，很难适应不同的使用人群，同时大多数机械调节方式的张紧程度较为固定，致使头部较胖的人群戴起来过紧，头部较小的人群戴起来又过松，影响使用体验。In the existing technology, the back-end mechanism is generally an elastic stretchable fabric, or most of them use a mechanical adjustment mechanism, which is relatively cumbersome to adjust. At the same time, existing head-mounted devices have limited adaptability to different groups of people. Due to the inconsistent head shapes and sizes of children and adults, it may be too loose for children and tight and uncomfortable for adults. Moreover, even adults have different body shapes and head sizes. Therefore, existing head-mounted devices have limited adaptability and are difficult to adapt to different user groups. At the same time, the tension of most mechanical adjustment methods is limited. It is relatively fixed, causing people with fatter heads to wear it too tightly, and people with small heads to wear it too loosely, affecting the user experience.

The rear end mechanism 2 uses the tension spring 71 and the guide column 73 to ensure that the inner elastic frame 21 is always in the farthest position, that is, the initial position, before the inner elastic frame 21 is automatically pulled apart. The inner diameter of the display device is the largest. At the same time, during the motor tightening process, the inner elastic frame 21 has a guiding function when moving and will not deviate. The tension spring 71 can ensure automatic return while regardless of whether the motor 31 is powered on or off, regardless of the wire rope. Whether it is tightened or loosened, the stability of the entire rear end mechanism 2 can be ensured so that it will not shake. During operation, the size can also be adjusted manually, that is, the inner elastic frame 21 can be manually pulled. When the inner elastic frame 21 is manually pulled, the motor 31 and other structures will not be damaged.

At the same time, the first arc-shaped plate 211 The plate 211 drives the second arc-shaped plate 212 to contract and deform. At this time, the tension spring 71 will pull the first arc-shaped plate 211 backward to generate a damping force, so that the motor 31 retracts. When rolling, the first arc-shaped plate 211 and the second arc-shaped plate 212 can change smoothly. Similarly, when the motor 31 does not work and the head-mounted device 100 is detached from the brain, the tension spring 71 pulls the first arc plate 211 backward, so that when the inner elastic frame 21 is reset, the The wire rope connected to the motor 31 will also generate a forward pulling force to generate a damping force, so that when the inner elastic frame 21 returns to the initial position, the first arc plate 211 and the second arc plate 212 can change smoothly.

Specifically, it is determined whether the real-time pressure value endured by the inner elastic frame 21 meets the preset value; if not, that is, if the real-time pressure value is less than the minimum threshold, the motor 31 is started to rewind the traction rope 32 and tighten the inner elastic frame 21 . The elastic frame 21 stops the motor 31 until the real-time pressure value of the inner elastic frame 21 reaches the preset value, that is, if the real-time pressure value is greater than or equal to the minimum threshold and less than or equal to the maximum threshold. In this step, due to the installation of membrane pressure sensors with 45-degree directions on the left and right at the right rear and side rear, it is possible to detect the pressure in all directions when the inner elastic frame 21 with the entire rear end tightened is tightened forward. When a person puts it on and tightens the motor, the rubber column 214 will deform. At this time, the rubber column 214 will squeeze the film pressure sensor, thereby detecting the current pressure value of the second arc plate 212, and The pressure value is transmitted to the host 12 for processing. The host calculates the average value of the pressure values of the three membrane pressure sensors, and converts it through a preset algorithm to obtain the current real-time pressure of the second arc plate 212. pressure value and compare whether the average value matches the preset value. When the pressure value is compared with the preset value and does not meet the preset value, that is, is lower than the preset value, the motor is turned on and the inner elastic frame 21 is tightened until the real-time pressure of the inner elastic frame 21 is value reaches the preset value, the motor is turned off. When the motor winds up the steel wire rope, the steel wire rope can drive the first arc-shaped plate 211 to move forward, and its size shrinks and deforms. At the same time, the first arc-shaped plate 211 drives the second arc-shaped plate 211 to move forward. The shaped plate 212 shrinks and deforms. At this time, the tension spring 71 will produce a backward pulling force on the first arc plate 211 to generate a damping force, so that when the motor is rewinding, the first arc plate The plate 211 and the second arc plate 212 can change smoothly.
