Description

Technical Field

[0001] The present invention relates to the technical field of display and control terminals, and specifically to a vertical dual-screen portable terminal structure. Background Art

[0002] While meeting the performance indicators, display and control products increasingly focus on the user experience. Taking dual-screen portable terminals as an example, there is still much room for improvement in human-computer interaction and user-friendliness: high noise, large volume occupying space, poor operation comfort, and lack of aesthetic appearance, which cannot meet the advanced usage requirements of users.

[0003] The form of dual-screen portable terminals is usually a bottom chassis with a horizontal dual-screen configuration, which occupies a large space in the horizontal direction and is difficult to deploy in narrow cabins and cab spaces. In addition, the dual-screen layout methods of existing dual-screen portable terminals are mainly the following two. One is to arrange them on the BC surfaces respectively. The B-surface screen is connected to the front end of the chassis through a damping hinge, and the C-surface screen is fixed. The other is to arrange them all on the B-surface. The two are vertically arranged and connected through a damping hinge. The lower screen is connected to the front side of the chassis through a damping hinge.

[0004] Although the above-mentioned vertical dual-screen portable terminal can reduce the occupation of horizontal space, its screen layout is not reasonable enough. In the former case, the C-surface screen is flush with the chassis plane. If the terminal is placed horizontally, it is easy to cause reflection of top light, especially in outdoor usage scenarios, causing glare to the user. In addition, this layout method occupies the space of the keyboard and palm rest areas, resulting in poor user experience. In the latter case, the dual screens form a series cantilever beam structure, resulting in a relatively high center of gravity of the screens. The damping hinge of the lower screen needs to be designed with a large damping to overcome the gravity moment of the dual screens, which is not conducive to the user to open / close the screen. At the same time, under vibration and impact conditions, the high center of gravity of the series dual screens requires high structural strength, and it is difficult to ensure structural reliability. When the operator touches the screen, it may also cause the screen to shake and make accurate operation difficult. Therefore, a vertical dual-screen portable terminal structure is specifically proposed to improve the human-computer experience of dual-screen portable terminals. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the present invention provides a vertical dual-screen portable terminal structure, which solves the problems raised in the above background art.

[0006] To achieve the above objectives, the present invention is realized through the following technical solutions: A vertical dual-screen portable terminal structure includes a chassis. The front side of the top of the chassis is hinged with a lower screen through a first damping hinge. The back of the lower screen is hinged with an upper screen through a second damping hinge.

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

[0019] Please refer to Figures 1-5 , the embodiments of the present invention provide the following technical solutions: A vertical dual-screen portable terminal structure includes a chassis 5, and the front side of the top of the chassis 5 is hinged with a lower screen 2 through a first damping hinge 4, and the back of the lower screen 2 is hinged with an upper screen 1 through a second damping hinge 3.

[0020] As a preferred solution, in order to stably support the lower screen 2 after angle adjustment, foldable support link members 6 are hinged between the back of both sides of the upper screen 1 and the chassis 5. Specifically, the foldable support link member 6 includes two link rods 23, and the two link rods 23 are rotatably connected by a rotating shaft 8. One end of a link rod 23 is rotatably connected to one side of the lower screen 2, and one end of the other link rod 23 is hinged to one side of the chassis 5 through a third damping hinge 7. Further, in order to avoid the protrusion of the foldable support link member 6, grooves 9 are provided on the back of both sides of the chassis 5, and the grooves 9 are used in cooperation with the two link rods 23, that is, after the two link rods 23 are folded, they can be received in the grooves 9. In order to avoid the situation where the foldable support link member 6 squeezes the user's fingers when the lower screen 2 is received, flanging baffles 12 are fixedly installed on the back of both sides of the lower screen 2.

[0021] As a preferred solution, in order to realize the convenient unfolding of the lower screen 2, a grooved sliding block 10 is fixedly installed on the side of the upper screen 1 close to the lower screen 2, and a limit slide bar 11 that is used in cooperation with the grooved sliding block 10 is fixedly installed on the back of the top of the chassis 5. When the lower screen 2 and the upper screen 1 are in the received state, the grooved sliding block 10 and the limit slide bar 11 are in contact and form a sliding pair structure. When the upper screen 1 is unfolded, it drives the grooved sliding block 10 to slide on the limit slide bar 11. Through reverse extrusion, the lower screen 2 can be tilted at a certain angle to facilitate the user's use. Specifically, the user's hand acting point, the second damping hinge 3 and the sliding pair form a lever, and the sliding pair moves in the opposite direction to the user's hand acting point. The lower screen 2 is driven by the second damping hinge 3 to lift at a certain angle, greatly simplifying the dual-screen opening method and optimizing the user experience.

[0022] Further, in order to facilitate the unfolding of the upper screen 1, second finger grooves 13 are provided on both sides of the top of the upper screen 1.

[0023] As a preferred solution, a pull-out keyboard and touchpad integrated member 14 is slidably installed at the bottom of the chassis 5 through a sliding guide member 15. Specifically, mechanical limit blocks 16 are fixedly installed on both sides of the bottom of the pull-out keyboard and touchpad integrated member 14, and a spring bead locking member 17 is fixedly installed in the sliding guide member 15. In order to facilitate the removal of the pull-out keyboard and touchpad integrated member 14 from the chassis 5, a first finger groove 18 is provided at the front side of the bottom of the pull-out keyboard and touchpad integrated member 14.

[0024] As a preferred solution, in order to facilitate the carrying of the terminal, a pull-out handle 24 is fixedly installed in the middle of the front of the chassis 5. The position of the pull-out handle 24 is collinear with the center of gravity position of the terminal. The pull-out handle 24 adopts a hidden design. In order to facilitate the access of the pull-out handle 24, chamfers 25 are provided at the corners of the top and bottom of the front of the chassis 5.

[0025] Further, in order to ensure the long-term and stable use of the terminal, rubber corner protectors 19 are sleeved around the upper screen 1 and around the bottom of the chassis 5.

[0026] As a preferred solution, an air inlet 20 is provided on the front of the chassis 5 and above the integrated pull-out keyboard and touchpad 14, an air outlet 21 is provided on the back of the chassis 5, and a number of left and right aviation plug connectors 22 are provided on both sides of the back of the chassis 5 and located at the air outlet 21.

[0027] Further explanation, a USB interface is also provided at the front right of the chassis 5. In order to prevent dust from blocking the USB interface when it is not in use, as shown in the attachment Figure 5 where A is a sealing plate, the USB structure is arranged at the place blocked by the sealing plate, and the sealing plate is used to block the USB interface.

[0028] When in use, directly unfold the upper screen 1, the upper screen 1 drives the grooved slider 10 to slide on the limit slide bar 11, so that the lower screen 2 tilts at a certain angle. Then, according to the usage needs, rotate the lower screen 2. Under the setting of the first damping hinge 4, the lower screen 2 maintains the adjusted angle. At the same time, the lower screen 2 drives a connecting rod 23 to move upward, so that the foldable support link member 6 unfolds.

[0029] It should be noted that when the lower screen 2 is adjusted to the maximum angle and there is still a situation of reflection and glare, adjust the angle of the upper screen 1. Under the setting of the second damping hinge 3, the upper screen 1 maintains the adjusted angle to further avoid the situation of reflection and glare of the lower screen 2.
