Referring to fig. 1-3, a linkage assembly is disposed in the mounting cavity 330 of the sliding rail 300, and the display housing 200 can be slidably connected to the fixed housing 100 through the linkage assembly, so that the display housing 200 can be pushed to the forehead from the eyes of the user.
Referring to fig. 3 to 6, the linkage assembly includes a first linkage arm 410, a second linkage arm 420, two third linkage arms 430, a fourth linkage arm 440, a fifth linkage arm 450, a limiting shaft 452, and a torsion spring 470. The two ends of the first linkage arm 410 extend into the two first limiting grooves 310 respectively, and simultaneously extend out of the sliding rail 300 from the first limiting grooves 310 and are connected to the display housing 200, so that the display housing 200 can be utilized to drive the first linkage arm 410 to move along the opening direction of the first limiting grooves 310.
Referring to fig. 4 to 6, both ends of the second link arm 420 respectively extend into the two second limiting grooves 320, and the center line of the second link arm 420 is parallel to the center line of the first link arm 410. The two third link arms 430 are respectively located at two outer sidewalls of the slide rail 300, and one end of each third link arm 430 is sleeved to one end of the first link arm 410, so that the first link arm 410 is rotatably connected to the third link arm 430, while the other end of the third link arm 430 is sleeved to one end of the second link arm 420, so that the second link arm 420 is rotatably connected to the third link arm 430.
Referring to fig. 5 and 6, the fourth linkage arm 440 has a bent plate structure, and the fourth linkage arm 440 includes a first arm body 441 and a second arm body 442, wherein a portion located at an upper side of the fourth linkage arm 440 is defined as the first arm body 441, and a portion located at a lower side of the fourth linkage arm 440 is defined as the second arm body 442. The opposite ends of the first arm 441 and the second arm 442 are fixedly connected, and the center plane of the first arm 441 intersects with the center plane of the second arm 442 and may form an obtuse angle, in the present application, both the first arm 441 and the second arm 442 are inclined toward the inner side.
The connection between the first arm 441 and the second arm 442 is rotatably connected to the sliding rail 300 through a first rotation shaft 443, such that the first linkage arm 410 can rotate around the first rotation shaft 443. The other end of the first arm 441 extends toward the upper side and the outer side, while the other end of the second arm 442 extends toward the lower side and the inner side, so that the bottom end of the fourth link arm 440 may extend above the second link arm 420.
Referring to fig. 4 and 5, the top end of the fifth link arm 450 is rotatably connected to the slide rail 300 through the second rotation shaft 480, and the other end thereof extends toward the direction of the first link arm 410. Because the fifth linkage arm 450 is located outside the fourth linkage arm 440, a through groove 451 is formed at a position of the fifth linkage arm 450 near the top end thereof, the through groove 451 is formed along the length direction thereof, and the top end of the first arm body 441 is rotatably clamped into the through groove 451 through the third rotating shaft 460, so that the top end of the fourth linkage arm 440 can rotate relative to the fifth linkage arm 450 and can slide a distance relative to the fifth linkage arm 450.
Referring to fig. 4 and 5, a protrusion 453 is disposed on a side wall of the fifth link arm 450, and the protrusion 453 is disposed near a bottom end of the fifth link arm 450 and protrudes toward the first limiting slot 310. The slide rail 300 is provided with a limiting shaft 452 near the bottom end of the fifth link arm 450, the center line of the limiting shaft 452 is parallel to the center line of the first link arm 410, the limiting shaft 452 is located outside the fifth link arm 450 and below the protruding part 453, so that the bottom end of the fifth link arm 450 can be abutted to the limiting shaft 452, and the limiting shaft 452 is used for limiting the limit position of the rotation of the fifth link arm 450.
Referring to fig. 4 and 5, the torsion spring 470 is sleeved outside the first rotation shaft 443 and between the fourth linkage arm 440 and the fifth linkage arm 450, one end of the torsion spring 470 can be abutted to the fourth linkage arm 440, and the other end of the torsion spring 470 can be abutted to the fifth linkage arm 450.
Referring to fig. 1 to 10, when the user wears the display device, the display housing 200 shields the entire periphery of the user's eye field of view, and if something else needs to be temporarily handled by the user, the user can push the display housing 200 upward. When the display housing 200 is pushed, the display housing 200 drives the first linkage arm 410 to slide upwards along the first limiting groove 310 until the first linkage arm 410 abuts against the protrusion 453 of the fifth linkage arm 450. While the second link arm 420 may be moved along the second limiting groove 320 by the driving of the third link arm 430 until the second link arm 420 abuts against the bottom end of the fourth link arm 440.
As the display housing 200 is further pushed up, the first link arm 410 applies a pushing force to the protrusion 453, so that the fifth link arm 450 rotates inward around the second rotation shaft 480. Since the tip of the fourth link arm 440 is inserted into the through-slot 451 through the third rotation shaft 460, the tip of the first arm 441 may slide upward along the through-slot 451 so that the fourth link arm 440 may be rotated at an angle to the outside about the first rotation shaft 443, at which time the second arm 442 is rotated toward the outside while compressing the torsion spring 470 so that it may deviate from the second link arm 420. The first linkage arm 410 may drive the second linkage arm 420 to move along the second limiting groove 320 through the third linkage arm 430, so that the display housing 200 can be pushed to the forehead from the eyes of the user.
Meanwhile, when the first and second link arms 410 and 420 slide along the first and second limiting grooves 310 and 320, respectively, the first link arm 410 is separated from the protrusion 453, so that the pushing force applied to the fifth link arm 450 disappears, and the torsion spring 470 can convert its elastic force into a pushing force to drive the fourth link arm 440 and the fifth link arm 450 to reset.
Referring to fig. 5-10, the sliding rail 300 is further provided with a limiting assembly at a middle position of the mounting cavity 330, where the limiting assembly includes a first limiting arm 510, a second limiting arm 520, two third limiting arms 530, and two driving arms 540.
