The base 110 is used to carry electronic components such as a central processing unit, a hard disk, a memory, a battery, a motherboard, a slot, a keyboard, a speaker, a microphone, and the like. The back cover 120 is pivotally connected to the base 110 and has an accommodation space AS. The support plate 130 has a first end E1 and a second end E2 opposite to the first end E1. The first end E1 is pivotally connected to the base 110 and the back cover 120. The main display 140 is pivotally connected to the second end E2 of the support plate 130 , wherein the main display 140 adopts a display panel or a touch panel. The front lens 150 is disposed on a top TE of the back cover 120 and is located above the main display 140. The front lens 150 is misaligned with the accommodation space AS.

Referring to FIG. 2A , in a folded state, the support plate 130 is located in the accommodation space AS and is attached to the back cover 120 . The main display 140 is stored in the accommodation space AS and covers the support plate 130 . A display surface 141 of the main display 140 is attached to the back cover 120 . on the base 110. In short, the back cover 120 is stacked on the base 110, and the support plate 130 and the main display 140 are stored in the accommodation space AS. Referring to Figures 1A and 2B, in an unfolded state, there is an included angle CA between the back cover 120 and the base 110.

FIG. 3A is a schematic side view of the main display and support plate of FIG. 2B unfolded on the back cover. FIG. 3B is a schematic plan view of the main display of FIG. 2C overlapping the base. FIG. 3C is a schematic plan view of the back cover of FIG. 2C unfolded 135 degrees.

Referring to FIG. 1A, FIG. 1B and FIG. 3B, the electronic device 100 includes a pair of display 180, which is disposed on the back cover 120 (for example, distributed on the top TE and the accommodation space AS of the back cover 120), and the slave display 180 and the front lens 150 are offset from each other, and the part of the secondary display 180 located at the top TE is flush with the front lens 150 .

Referring to FIG. 1A , when the back cover 120 is unfolded on the base 110 and the main display 140 overlaps a part of the secondary display 180 , the secondary display 180 outputs a reduced icon and function shortcut keys on another part of the top TE, which is conducive to Users are reminded and can switch interfaces through function shortcut keys. Referring to FIG. 3B , when the main display 140 is separated from the accommodation space AS and misaligned with the secondary display 180 , the secondary display 180 is suitable for outputting a complete interface.

Referring to FIGS. 1A , 1C and 2B , in a first mode, the user drives the back cover 120 to pivot relative to the first rotating shaft 171 , because the first torsion force of the back cover 120 pivoting on the first rotating shaft 171 is greater than the support plate 130 Pivoted to the second torque of the second rotating shaft 172, the back cover 120 can synchronously drive the support plate 130 and the main display 140 to unfold on the base 110, and the angle CA of the back cover 120 relative to the base 110 expands from 0 degrees to 100 degrees. In addition, The first torque of the first rotating shaft 171 is greater than the third torque provided by the third rotating shaft 173 to the support plate 130 . The support plate 130 is overlapped with the back cover 120 , the main display 140 is overlapped with the support plate 130 , and both the support plate 130 and the main display 140 are stored in the accommodation space AS of the back cover 120 .

Referring to FIG. 1C and FIG. 3A , in this embodiment, in the second mode, there is no linkage module 160 between the support plate 130 and the main display 140 , so the support plate 130 and the main display 140 pivot relative to the second rotation axis 172 The main display 140 is unfolded on the back cover 120, and the main display 140 is folded on the support plate 130. A first angle A1 is formed between the support plate 130 and the back cover 120.

Referring to FIGS. 1B and 2C , in the third mode, the support plate 130 is unfolded on the back cover 120 , the main display 140 is unfolded on the support plate 130 to form a second angle A2 , and the third angle between the back cover 120 and the support plate 130 is An angle A1 is an acute angle.

Referring to FIG. 1C and FIG. 3B , in the fourth mode, the support plate 130 pivots relative to the second rotation axis 172 to unfold on the back cover 120 , a first angle A1 is formed between the support plate 130 and the back cover 120 , and the main display 140 is unfolded. A second angle A2 is formed on the support plate 130 . Wherein, the first angle A1 is a right angle or an obtuse angle and the second angle A2 is an obtuse angle or an obtuse angle, so that the main display 140 overlaps the base 110 . Since the second torque provided by the second rotating shaft 172 to the supporting plate 130 is greater than the third torque provided by the third rotating shaft 173 to the supporting plate 130 , the user is suitable to apply force on the main display 140 to drive the supporting plate 130 to unfold relative to the back cover 120 , thereby adjusting the position and viewing angle of the main display 140 on the base 110 .

Furthermore, in the fourth mode of this case, the main display 140 is adapted to overlap on the base 110 without covering the keyboard, or the main display 140 is adapted to directly lean against the base 110 to ensure the stability of the main display 140. Reduce shaking.

Referring to FIG. 3B , the back cover 120 has a gap G suitable for receiving the first end E1 of the support plate 130 . In addition, since the first end E1 of the support plate 130 has an L-shaped structure, when the first end E1 of the support plate 130 does not enter the gap G, the back cover 120 will be stopped by the first end E1 when it directly rotates relative to the base 110. This prevents the back cover 120 from colliding with the main display 140 . Furthermore, the notch G of the back cover 120 can accommodate the first end E1 of the support plate 130, so the appearance integrity of the base 110 can be maintained.

Referring to FIG. 3C , in the fourth mode, a first angle A1 is formed between the support plate 130 and the back cover 120 , and the main display 140 is unfolded on the support plate 130 to form a second angle A2 , in which the angle between the back cover 120 and the base 110 is The included angle CA is 135 degrees. Here, in the first mode, the user is allowed to continue to expand 25 degrees toward the first rotation direction T1 to facilitate adjusting the viewing angle of the front lens 150 .

FIG. 4A is a schematic plan view of the main display of the electronic device clamped to the base according to another embodiment of the present invention. FIG. 4B is an exploded schematic diagram of the shielding module of the electronic device of FIG. 4A .
