Description

Technical Field

[0001] This invention relates to a display module, and more particularly to an external display module. Background Technology

[0002] External display modules are designed to connect to the flip cover of laptops, allowing users to enjoy a dual-screen or triple-screen experience. An external display module consists of a module base and a screen unit, with the screen unit pivotally connected to the module base. The screen unit can rotate relative to the module base between a folded and unfolded position. In existing technology, to avoid interference between the screen unit and the module base during flipping, the edge of the screen unit is relatively far from the side of the module base. When in use, users may perceive an excessively large gap between the external display module's screen and the laptop's screen. Summary of the Invention

[0003] The present invention provides an external display module to address the problems of the prior art, suitable for detachably connecting to an electronic device, comprising a module base and a first screen unit. The module base includes a first base side, two first slide rails, and at least one first guide groove. The first screen unit is rotatably connected to the module base, wherein the first screen unit includes a first screen, a first pivot, at least one first guide member, and two first sliders. The first pivot is located at the edge of the first screen unit, the first guide member is fixed to the first pivot and rotates with the first pivot, the first slider is connected to the first pivot, the first guide member is inserted into and guided by the first guide groove, and the first slider is adapted to slide within the first slide rail. During the rotation of the first screen unit from a first folded position to a first unfolded position, the edge of the first screen unit moves closer to the first base side.

[0004] In one embodiment, the first screen unit includes two first extension plates, the first pivot is rotatably connected to the first extension plates, and the first slider is fixed to the first extension plates.

[0005] In one embodiment, the first slide rails extend along a first direction, and the first guide is inserted into the first guide groove along a second direction perpendicular to the first direction.

[0006] In one embodiment, during the process of the first screen unit rotating from the first folded position to the first unfolded position, the first guide member is guided from a first guide groove end to a second guide groove end of the first guide groove, the second guide groove end being closer to the side of the first base than the first guide groove end, and the extension direction of the first guide groove having an angle between the first direction and the first direction, the angle being between 20° and 70°.

[0007] In one embodiment, the external display module further includes a second screen unit rotatably connected to the module base. The second screen unit includes a second screen, a second pivot, at least one second guide, and two second sliders. The second pivot is located at the edge of the second screen unit. The second guide is fixed to the second pivot and rotates with it. The second sliders are connected to the second pivot. The module base also includes a second base side, two second slide rails, and at least one second guide groove. The second guide is inserted into and guided by the second guide groove. The second sliders are adapted to slide within the second slide rails. During the rotation of the second screen unit from a second folded position to a second unfolded position, the edge of the second screen unit moves closer to the second base side.

[0008] In one embodiment, when the first screen unit is in the first folding position and the second screen unit is in the second folding position, the first screen unit is at least partially located between the second screen unit and the module base.

[0009] In one embodiment, the second screen unit further includes a push-top unit disposed at the edge of the second screen unit. When the second screen unit is rotated from the second folded position to the second unfolded position, the push-top unit pushes against the side of the first screen unit, causing the first screen unit to rotate from the folded position.

[0010] In one embodiment, the second screen unit includes two second extension plates, the second pivot is rotatably connected to the second extension plates, the second slider is fixed to the second extension plates, and during the process of the second screen unit rotating from the second folded position to the second unfolded position, the second guide is guided from a third guide groove end of the second guide groove to a fourth guide groove end of the second guide groove, the fourth guide groove end being closer to the side of the second base than the third guide groove end.

[0011] In one embodiment, the second guide channel includes an idle section and a guide section. The idle section is located at the end of the third guide channel. During the process of the unit pushing the first screen unit, the second guide moves in the idle section, and the edge of the second screen unit has not yet approached the side of the second base. After the second guide enters the guide section and moves toward the end of the fourth guide channel, the edge of the second screen unit approaches the side of the second base.

[0012] In embodiments of the present invention, through the design of a first slide rail, a first guide groove, a first guide member, and a first slider, the edge of the first screen unit moves closer to the side of the first base during the rotation of the first screen unit from the first folded position to the first unfolded position. Therefore, interference between the first screen unit and the module base can be avoided during rotation. In the unfolded state, the gap between the first screen of the first screen unit and the screen of the notebook computer can be reduced to improve the user's operating experience.
