[0003] Table 1 Main structural forms of existing dual-screen display mechanisms

[0004] Serial Number Name Screen Arrangement Screen Expansion Method Whether Single Screen Use is Supported Whether Screen Angle Adjustment is Supported Whether the Dual Screens are Centered After Expansion 1 Type A Vertical Single Fixed-Axis Rotation No Only One Screen is Supported Yes 2 Type B Horizontal Single Fixed-Axis Rotation No Only One Screen is Supported No 3 Type C Vertical Dual Fixed-Axis Rotation No Both Screens are Supported Yes 4 Type D Horizontal Sliding Yes Neither is Supported Yes 5 Type E Horizontal Sliding + Single Fixed-Axis Rotation No Only One Screen is Supported Yes

[0055] Reference Figures 2 to 11 will be used to explain the mechanism provided in this embodiment in detail below.

[0056] 1) Description of the overall machine composition and various working states

[0057] A portable electronic device applying the present invention is composed of a sliding connection locking component 4, a three-axis flipping connection component 3, a main display component 1, a secondary display component 2, and a chassis 5, and its composition is asFigure 2 as shown

[0058] Both the main display screen assembly 1 and the secondary display screen assembly 2 are installed on the three-axis flipping connection assembly 3, and then connected to the chassis 5 through the sliding connection locking assembly 4. When a vertically arranged screen layout needs to be formed, unlock the locking hook 15 on the side of the secondary display screen assembly 2, flip the secondary display screen assembly 2 upward to an appropriate position, and then flip the main display screen assembly 1 upward by a certain angle to form a vertically arranged dual-screen layout, with each screen in an independently adjustable angle state, and the effect is as Figure 3 shown

[0059] When a horizontally arranged screen layout needs to be formed, unlock the locking hook 15 on the side of the secondary display screen assembly 2, flip the secondary display screen assembly 2 to the right to a position flush with the main display screen assembly 1 to form a horizontally arranged dual-screen layout with the secondary screen offset, and the effect is as Figure 4 shown

[0060] Unlock the indexing pin 8 and the non-detachable screw 7 on the sliding connection locking assembly 4. After flipping the main display screen assembly 1 and the secondary display screen assembly 2 upward, slide the dual screens to the extreme left position, lock the indexing pin 8, and then close the main display screen assembly 1 and the secondary display screen assembly 2 downward to form a horizontally arranged dual-screen centered display state, and the effect is as Figure 5 shown

[0061] When in the horizontally arranged dual-screen state, whether the secondary screen is offset or centered, the main display screen assembly 1 and the secondary display screen assembly 2 can both be flipped upward by a certain angle to meet the viewing angle requirements of different operators. The effect of adjusting the pitch angle of the horizontal arrangement is as Figure 6 shown

[0062] 2) Sliding connection locking assembly 4

[0063] The function of the sliding connection locking assembly 4 is to enable the secondary display screen assembly 2 to have two modes, namely the secondary screen offset state and the dual-screen centered display state, when horizontally flipped to form a horizontally arranged dual-screen layout. This assembly mainly consists of a connecting beam 4 with a T-shaped chute 41, an indexing pin 8, and a non-detachable screw 7, and its composition is as Figure 7 shown. The sliding connection locking assembly 4 connects the three-axis flipping connection assembly 3 and the chassis 5 together and is locked by 1 non-detachable screw 7 and 1 indexing pin 8. Lock the non-detachable screw 7 during the transportation of the device. When the device is in use, the non-detachable screw 7 can be loosened. When it is necessary to move the dual screens to the centered display state, lift the pin of the indexing pin 8 and rotate it 60 degrees to the unlocked state, pull the dual screens to the extreme position (centered left and right), and then lock the indexing pin 8 to ensure that the two display screens in this state will not move left and right

[0064] 3) Three-axis flipping connection assembly 3

[0065] The function of the three-axis flipping connection component 3 is to connect the main display screen component 1 and the secondary display screen component 2, and enable the main display screen component 1 to rotate within a range of 0 - 60 degrees in the vertical direction, and enable the secondary display screen component 2 to rotate coaxially with the main display screen component 1 in the vertical direction, with a rotation range of 0 - 170 degrees. At the same time, it can also enable the secondary display screen component 2 to flip 180 degrees horizontally around its side. All three rotation axes have appropriate damping, allowing the display screen component to stop arbitrarily within its rotation range.

[0066] The three-axis flipping connection component 3 mainly consists of a connecting piece 10, a vertical axis 11 of the main display screen component 1, a vertical axis 12 of the secondary display screen component 2 (the three are coaxially arranged on top of the transition plate 9), and a horizontal rotation axis 13 of the secondary display screen component 2, and its composition is as Figure 8 shown.

[0067] When it is necessary to form a display state with two screens arranged vertically, first rotate the secondary display screen component 2 and the transition plate 9 upwards to an appropriate position, and the main display screen component 1 can rotate upwards independently by a certain angle. When it is necessary to form a display state with two screens arranged horizontally, first flip the secondary display screen component 2 to the right by 180 degrees alone, and the main display screen component 1 and the transition plate 9 remain stationary.

[0068] 4) The main display screen component 1 and the secondary display screen component 2

[0069] The external dimensions of the main display screen component 1 and the secondary display screen component 2 are exactly the same. To ensure the display effect when the two screens are arranged horizontally, the display screens 16 are both centered. The lower part of the main display screen component 1 is connected to the chassis 5 through a ball catch 14, and the upper part of the main display screen component 1 is connected to the vertical axis 11 of the three-axis flipping connection component 3. The lower left part of the secondary display screen component 2 is connected to the chassis 5 through a spring lock hook 15, and the upper right part of the secondary display screen component 2 is connected to the horizontal rotation axis 13 of the three-axis flipping connection component 3.

[0070] The main display screen component 1 mainly consists of a display screen 16, a front shell 17 of the main display screen, a rear cover plate 18 of the main display screen, and a ball catch 14, and its composition is as Figure 9 shown.

[0071] The secondary display screen component 2 mainly consists of a display screen 16, a front shell 19 of the secondary display screen, a rear cover plate 20 of the secondary display screen, and a spring lock hook 15, and its composition is as Figure 10 shown.

[0072] 5) The chassis 5

[0073] Above the chassis 5, there are at least two pulley groups 21 installed. The pulley groups 21 can move in the chute 41 of the sliding connection locking component 4 to achieve two states: the offset of the secondary screen and the centered display of the dual screens when the screens are arranged horizontally. There are also two indexing pin holes 51 provided above the chassis 5 for locking the indexing pin 8 in the two states of the offset of the secondary screen and the centered display of the dual screens. Above the chassis 5, there is also a mounting hole 52 for a non-dropping screw 7. When the device needs to be transported, the non-dropping screw 7 can be locked to ensure that the screen does not move. Two catch seats 22 are arranged below the chassis 5 for locking the main display component 1 in the two states of the centered display in the horizontal direction of the dual screens and the arrangement in the vertical direction of the dual screens. The composition of the chassis 5 is as Figure 11 shown.

[0074] Compared with the prior art, this embodiment has at least the following effects:

[0075] An adaptive dual-screen display mechanism provided by the present utility model can support two layouts of the dual screens arranged vertically and horizontally at the same time. When arranged vertically, the two displays can be independently adjusted in angle respectively. When arranged horizontally, the pitching angles of the two displays can be adjusted simultaneously and support two modes of offset display and centered display;

[0076] The structure layout of the present utility model is compact, labor-saving to unfold, quick to lock and unlock, and has good anti-vibration and impact resistance;

[0077] By means of technical means such as appropriately scaling the screen size, replacing different locking and unlocking mechanisms, and adjusting the position of the horizontal rotation axis, the present utility model can be adapted to different chassis layouts, thereby forming a variety of different devices;

[0078] Through experimental verification, a portable electronic device adopting the present utility model can work reliably at -40°C to +55°C and can effectively resist salt spray erosion and mold growth.

[0079] Through the description of the specific implementation manners, it should be possible to understand more deeply and specifically the technical means and effects adopted by the present utility model to achieve the predetermined purpose. However, the attached drawings are only for reference and illustration, and are not used to limit the present utility model.
