The second through hole 520 corresponds to the first through hole 412 of the chain knuckle 400, so that the second through hole 520 is located inside the tail knuckle 500.
Referring to fig. 5, 8 and 9, the end of the tail joint 500 facing away from the chain joint 400 is concavely formed with a limiting groove 530, and the limiting groove 530 is communicated with the second through hole 520. The end of the traction rope 230 is connected with a limit pin 231, and the limit pin 231 can be snapped into the limit groove 530, so that the end of the traction rope 230 is fixed to the tail joint 500.
The end of the strap 300 is inserted into the fixing groove 510, so that the strap 300 and the tail joint 500 are relatively fixed, thereby ensuring that the chain joint 400 sleeved outside the strap 300 does not fall off, shift in position, etc.
Referring to fig. 1 and 2, a protective cover 600 is sleeved on the outer side of the headband, and the protective cover 600 is made of a flexible elastic material, so that the protective cover 600 has a certain elastic deformation property, and the protective cover 600 is made of a high-density sponge. The protective cover 600 can prevent the headband from being directly attached to the head of the user, thereby relieving the pressure of the headband on the head and improving the wearing comfort.
Referring to fig. 1 to 9, since the head circumference of the user varies within a general range, the user can be divided into different wearing gear positions according to the above range. The number of the pin holes 221 formed on the traction wheel 220 can be reasonably designed according to the above range, and when the magnetic pin shafts 260 are penetrated into different pin holes 221, the tightness of the traction rope 230 is different. Because the tightness of the traction rope 230 can affect the rotation angle of the adjacent chain joints 400, the curvature of the head bands is different, so that the wearing space enclosed by the two head bands is different, and the head-mounted display device can adjust different wearing gears. Therefore, the head-mounted display device can be suitable for users with different head sizes, and the curvature of the head band can be adjusted by using the tightness of the traction rope 230, so that the adjustment mode can be simplified, and the user can wear the head-mounted display device conveniently.
Referring to fig. 1 to 9, the headband adjusts the bending state by using the band body 300 and the chain joints 400 sleeved outside the band body, and the plurality of chain joints 400 are sequentially hinged, so that the headband has a combination of rigidity and elasticity, has better reliability and stronger dynamic stability, is not easy to shake and fall off in activities such as games, sports and the like, and improves the safety and stability in use of the head-mounted display device.
One end of the traction rope 230 is wound on the traction wheel 220, the other end of the traction rope is sequentially penetrated through a plurality of hinged chain joints 400, and the rotation and the stop of the traction wheel 220 can be controlled by using a control mechanism, so that the tightness of the traction rope 230 is adjusted. Because the band body 300 is an arc-shaped elastic strip structure, the concave surface of the band body 300 is disposed towards the inner side, and the first through hole 412 is located at the inner side of the chain joint 400, when the chain joint 400 is tightened, the inner sides of the chain joint 400 are close to each other, so that the headband is bent towards the inner side, and the headband is tightly attached to the head of a user, so that the head-mounted display device can be suitable for users with different head circumferences.
The foregoing has provided a head mounted display device for the purposes of providing a detailed description of the principles and embodiments of the present application, and specific examples have been provided herein to assist in understanding the methods of the present application and their core ideas; meanwhile, as those skilled in the art will have modifications in the specific embodiments and application scope in accordance with the ideas of the present application, the present description should not be construed as limiting the present application in view of the above.
