[0041] In the embodiment, the unfolding manner of the three-fold computer is: first, opening the three displays to 90° position, then turning the lower display 4 forward until the lower side of the lower display 4 contacts the first position of the keyboard body 1 (for example, the lower side of the lower display 4 contacts the upper part of the keyboard body 1), at this time, the locking mechanism on the lower display 4 cooperates with the screen locking block on the keyboard body 1 to realize the locking and fixing of the lower display 4; then turning the upper display 2 forward above the middle display 3 to complete the unfolding of the three displays, as shown in Figure 2 .
[0042] In the embodiment, the folding manner of the three-fold computer is: turning the upper display 2 away from the user until the back of the upper display 2 is attached to the back of the middle display 3; then unlocking the cooperation between the locking mechanism and the screen locking block, turning the lower display 4 away from the user until the front of the lower display 4 is attached to the front of the middle display 3; then turning the three displays downward until the back of the lower display 4 is attached to the upper part of the keyboard body 1 to complete the folding of the three displays, as shown in Figure 1 .
[0043] In some embodiments of the embodiment, the lower side of the upper display 2 and the upper side of the middle display 3 are respectively provided with magnetic members, when the upper display 2 is turned upward to the position above the middle display 3, the upper display 2 and the middle display 3 are fixedly connected through the attraction force of the magnetic members.
[0044] For example, the magnetic members are permanent magnets embedded in the lower side of the upper display 2 and the upper side of the middle display 3.
[0045] In some embodiments of the embodiment, the locking mechanism includes a locking pin, and the screen locking block is provided with a lock hole matched with the locking pin, and the locking mechanism and the screen locking block are fixedly matched by inserting the locking pin into the lock hole.
[0046] In some embodiments of the embodiment, as shown in Figure 3 , one end of the locking pin extends to the front of the lower display 4 and is fixedly connected with a knob 6, and the other end of the locking pin is provided with a radially protruding limiting part 8; the knob 6 is formed with a non-circular arc-shaped matching part, and the front of the lower display 4 is provided with a groove matched with the shape of the matching part; the lock hole is provided with a clamping structure matched with the limiting part 8; the locking pin is configured such that the limiting part 8 on the locking pin cooperates with the clamping structure, so that in the locked state, the limiting part 8 and the clamping structure form axial limiting, and the matching part is embedded in the groove.
[0047] Specifically, the lock pin is arranged in a mounting hole in the back of the lower display 4, and one end of the lock pin extends to the front of the lower display 4 and is fixedly connected with a knob 6. The knob 6 is formed with a non-circular arc-shaped matching part, and correspondingly, a groove with a shape matching the matching part is arranged on the front of the lower display 4 beside the mounting hole. The other end of the lock pin is provided with a limiting part 8 which protrudes radially from the column body of the lock pin and forms a T-shaped end structure together with the column body. The lock hole is formed with a clamping structure. For example, the clamping structure includes a blocking part 9 on the side wall of the lock hole, and the blocking part 9 is formed with a through groove at the opening of the lock hole. The profile of the through groove matches the profile of the limiting part 8, and the limiting part 8 is allowed to pass through the through groove in a specific orientation.
[0048] The locking process is as follows: first, rotate the pin shaft 7 to ensure that the orientation of the limiting part 8 is consistent with the orientation of the through groove, at this time the limiting part 8 can pass through the through groove, so as to completely insert the lock pin into the lock hole, as shown in FIG. 6. Figure 4 Then rotate the knob 6 to rotate the lock pin together. After the lock pin is rotated, the limiting part 8 thereon is rotated to a position where the limiting part 8 and the blocking part 9 axially abut each other, forming axial limiting, thereby preventing the lock pin from being withdrawn from the lock hole, as shown in FIG. 7. Figure 5 At the same time, the matching part of the knob 6 is completely embedded in the groove on the front of the lower display 4 after rotation, which prevents the lock pin from continuing to rotate. At this time, through the axial limiting of the limiting part 8 and the blocking part 9, and the circumferential limiting of the matching part and the groove, the stable locking of the lower display 4 relative to the keyboard body 1 is achieved.
[0049] The unlocking process is as follows: rotate the knob 6, the knob 6 rotates the lock pin, so that the orientation of the limiting part 8 is re-aligned with the orientation of the through groove, thereby removing the axial blocking of the blocking part 9. At the same time, the matching part of the knob 6 is separated from the groove, which removes the constraint on the rotation of the lock pin, so that the lock pin can be vertically pulled out of the lock hole, and the lower display 4 is unlocked.
[0050] The locking mechanism in the embodiment realizes stable locking and convenient unlocking through the axial limiting cooperation of the limiting part 8 and the clamping structure, and the circumferential embedding of the matching part and the groove, and forms a mechanical locking system with clear structure and reliable operation, thereby ensuring the stability of the equipment in the unfolded state.
[0051] In some embodiments of the embodiment, the upper surface of the keyboard body 1 is provided with a receiving groove. The receiving groove is configured to accommodate the end of the lock pin in the unlocked state, such as the limiting part 8 and the adjacent part of the column body of the pin shaft 7, in the folded state.
[0052] In some embodiments of the embodiment, anti-slip stripes, protrusions or knurl structures are arranged on the operation surface of the knob 6, so as to enhance the friction force during operation and effectively prevent slipping during operation.
[0053] In some embodiments of the present application, the damping hinge comprises a hollow hinge shaft, and the electrical connection cables between the upper display 2 and the middle display 3 and between the lower display 4 and the middle display 3 are arranged inside the corresponding hinge shafts, so that the cables are accommodated inside the hinge, which helps to reduce exposure, regularize wiring and reduce the risk of cable wear.
[0054] In some embodiments of the present application, the upper part of the keyboard body 1 is provided with a lock screen slider 5, the lock screen slider 5 is provided with a lock tongue, and the upper side edge of the upper display 2 is provided with a slot; when the upper display 2, the middle display 3 and the lower display 4 are in a folded state, the slot corresponds to the position of the lock tongue, and the sliding stroke of the lock screen slider 5 covers the position where the lock tongue is inserted into or separated from the slot.
[0055] When the three-fold computer is needed to be opened, the lock screen slider 5 is first slid to make the lock tongue exit from the slot, so as to unlock all the displays; when the three-fold computer is folded, the folding of the three displays is first completed, and then the lock screen slider 5 is slid to make the lock tongue inserted into the slot, so as to realize the locking of the three displays.
[0056] In some embodiments of the present application, the upper side of the lower display 4 is provided with a handgrip for assisting the unfolding operation.
[0057] The above specific embodiments further illustrate the purpose, technical scheme and beneficial effects of the present application.
