Referring to fig. 1, the display device 100 is movably connected to the supporting frame 200 through two sets of flipping devices symmetrically disposed on two sides of the supporting frame 200, so as to ensure the accuracy of the position of the display device 100 during the reciprocating motion.
The direction in which the display device 100 approaches the support frame 200 is defined as a reference direction in this application, and thus the position along the reference direction is the front.
Referring to fig. 1, each set of turning devices includes a limiting plate 300 and an adapted hinge plate 400, wherein a rear end of the limiting plate 300 is connected to a side of the display device 100, while a front end of the hinge plate 400 is connected to a side of the support frame 200, and when the limiting plate 300 slides and turns relative to the hinge plate 400, the display device 100 can slide and turn relative to the support frame 200.
Referring to fig. 1 to 5, the limiting plate 300 is provided with a first slot 310, a second slot 320, a third slot 330 and a limiting hole 350, wherein the first slot 310 is linearly provided along a reference direction and is provided from a rear end of the limiting plate 300 to a position close to a front end thereof. The second slot 320 and the third slot 330 are both disposed near the front end of the limiting plate 300, and are both communicated to the front end of the first slot 310.
The second groove 320 and the third groove 330 are arc structures, and the concave surface of the second groove 320 and the concave surface of the third groove 330 are both disposed upward, the limiting hole 350 is located on the extension line of the third groove 330, and the limiting hole 350 is not communicated with the third groove 330. The central angle of the second groove body 320 is 80 ° -100 °, and preferably the central angle is 90 °; while the central angle of the third slot 330 is 80-90.
Referring to fig. 1-5, the hinge plate 400 is provided with a first slider 410 and an elastic ball post 420, wherein the first slider 410 is formed by combining a pull rivet post and a sliding gasket, so that the first slider 410 is assembled to the hinge plate 400. The end of the elastic ball stud 420 protrudes from the hinge plate 400, and the elastic ball stud 420 is made of an elastic material so that it has elastic deformation properties.
The first slider 410 can reciprocate in the first and second grooves 310 and 320, and at the same time, the elastic ball post 420 can reciprocate in the first and third grooves 310 and 330 and can be slid into the limiting hole 350 from the inside of the third groove 330. In this application, the elastic ball column 420 is located above the front side of the first slider 410, so that the elastic ball column 420 always moves in front of the first slider 410, and meanwhile, the third slot 330 is located above the second slot 320, so that the elastic ball column 420 and the first slider 410 can slide to the inside of the third slot 330 and the second slot 320 respectively.
In this application, the radius of the first slider 410 is greater than the radius of the elastic ball column 420, and the opening width of the second slot 320 is greater than the opening width of the third slot 330, so that interference between the first slider 410 and the elastic ball column 420 can be avoided.
Referring to fig. 1-5, in an initial state, the display device 100 and the supporting frame 200 are relatively fixed, and the first slider 410 is located at the rear end of the first slot 310. When the display device 100 is gradually pulled up to move in a direction away from the support frame 200, the first slider 410 slides in synchronization with the elastic ball column 420 within the first groove 310, and when the first slider 410 moves to the communication position of the first groove 310 and the second groove 320, the display device 100 is pulled up to the maximum position away from the support frame 200, and at this time the elastic ball column 420 has slid to the inside of the third groove 330. When the display device 100 is gradually turned upwards relative to the support frame 200, the first slider 410 slides from the first slot 310 to the inside of the second slot 320, while the elastic ball post 420 continues to slide inside the third slot 330. When the first slider 410 abuts against the front end portion of the second slot 320, the elastic ball post 420 can be clamped into the limiting hole 350 from the third slot 330, so that the display device 100 is fixed relative to the support frame 200, and the display device 100 is at the turned-over limit position, in this case, the display device 100 is turned over vertically above the support frame 200.
Referring to fig. 1 to 5, when a user needs to temporarily deal with a problem to obtain a real field of view, the user can quickly obtain the real field of view by stretching and turning the display device 100 without picking up the head-mounted display device. Meanwhile, since the display device 100 turned over to the upper side of the supporting frame 200 can be relatively fixed by the clamping force between the elastic ball posts 420 and the limiting holes 350, the hands of the user can be liberated, so that the user can process other matters conveniently.
Since the display device 100 stretched and separated from the support frame 200 is turned upward and may be fixed to the upper side of the support frame 200, the display device 100 does not interfere with the user's view at all, thereby facilitating the user to process other matters. Meanwhile, when the display device 100 is stretched along the first groove 310, the display device 100 is separated from the face of the user, so that when the end part of the first groove 310 is stretched and turned upwards, the display device 100 and the face of the user can be prevented from interfering, the face of the user can be prevented from being pressed in the adjustment process, and the wearing comfort of the head-mounted display device is ensured.
The display device 100 located above distributes pressure to the first wearing case 500 and the second wearing case 600 through the support frame 200, so that the weight of the entire head-mounted display device 100 can be more distributed on the head, thereby reducing the pressure on the face of the user and improving the wearing comfort.
The movement track of the first slider 410 and the elastic ball post 420 is fixed, so that the display device 100 can still maintain the accuracy of the position in the process of reciprocating movement, and the eyes of the user can be accurately aligned after the display device 100 is reset, thereby improving the wearing effect.
Referring to fig. 1 to 5, the limiting plate 300 is provided with a fourth groove 340 along the reference direction, and the fourth groove 340 and the first groove 310 are parallel to each other. The hinge plate 400 is correspondingly provided with a second slider 430 such that the second slider 430 can slide inside the fourth groove 340.
The opening length of the fourth slot 340 is equal to the opening length of the first slot 310, and when the display device 100 is gradually pulled up to move in a direction away from the support frame 200, the first slider 410 slides in the second slot 320, and simultaneously the second slider 430 slides in the fourth slot 340 synchronously. When the first slider 410 moves to the communication position of the first and second grooves 310 and 320, the second slider 430 slides to the front end of the fourth groove 340. When the first slider 410 slides from the first slot 310 to the second slot 320, the second slider 430 is always located at the end of the fourth slot 340 and rotates.
Because the first slot body 310 and the fourth slot body 340 are arranged in parallel, the first slider 410 and the second slider 430 can slide synchronously, so that the rotation, offset, dislocation and other phenomena of the limiting plate 300 in the process of being far away from the hinge plate 400 can be avoided, and the accuracy of the movement direction of the display device 100 when being separated is ensured.
Referring to fig. 1-5, the bottom of the front end of the limiting plate 300 has an arc structure, the hinge plate 400 is provided with a limiting pin 440, and the bottom of the limiting plate 300 can be placed on the limiting pin 440 to support the bottom of the limiting plate 300 by using the limiting pin 440. When the first slider 410 slides into the second groove 320, the limiting plate 300 rotates synchronously with respect to the hinge plate 400, so that the abutment position of the limiting pin 440 rotates from the bottom of the limiting plate 300 to the front end thereof, and the movement of the display device 100 is smoother.
The limit pin 440 applies an upward pushing force to the limit plate 300, so that the shear stress applied to the first slider 410 can be reduced, and bending and deformation of the first slider 410 during long-term use can be reduced. The turning track of the limiting plate 300 can be limited by the limiting pins 440, so that the movement accuracy of the display device 100 relative to the supporting frame 200 is improved, and the adjustment accuracy of the head-mounted display device in long-term use is maintained.
