Description

Terminal device

Technical Field

The application relates to the technical field of mobile communication, in particular to the technical field of mobile equipment, and specifically relates to a terminal device.

Background

With the development of communication technology, terminal devices such as smart phones are becoming more and more popular. With the increasing demand of the mobile phone industry for large screens and portability, and the further maturity of the flexible screen technology, the appearance and development of the folding screen mobile phone become a new trend of the future mobile phone technology. When new concept mobile phones are allowed and new generation foldable mobile phones are available, various manufacturers also accelerate the research and development of foldable mobile phones. Since the surface material of the folding screen cannot be used as a rigid material such as glass, and in order to protect the screen, the inner folding technology capable of well protecting the screen becomes a preferred solution in the market at present. However, when the screen of the folding screen mobile phone is folded, the folding position must form an angle R, and how to handle the angle R becomes a big problem of the inner folding screen.

The technology used in the market is to fix both ends of the screen to the corresponding casings, respectively, and to connect the middle part using a rotating shaft. When the mobile phone is folded, the screen is folded along with the shell until the screen is folded to zero, and a gap with the radius of 1.5-2 mm is formed in the middle of the shell and used for placing an R angle of the screen. By the implementation, the thickness of the folding screen mobile phone is 3-4 mm thicker than that of a conventional mobile phone, and discomfort caused when a user operates the mobile phone is caused. In addition, because a gap is formed in the middle of the shell, when the mobile phone is folded to zero, the shell of the mobile phone cannot well protect the screen, and the problems of screen scratch, screen damage and the like are easily caused.

Therefore, it is desirable to design a terminal device to solve the problems of the terminal device in the prior art.

Referring to fig. 1, an embodiment of the present application provides a terminal device. The terminal device includes: a foldable screen 110; a first housing 121 and a second housing 122 disposed to be symmetrical to each other; a first screen supporting plate 131 and a second screen supporting plate 132 are respectively provided in the first housing 121 and the second housing 122; the first screen support plate 131 and the second screen support plate 132 are respectively used for bearing corresponding partial screens 110; a third housing 123 is provided at an opposite side between the first housing 121 and the second housing 122. Gear boxes 141 are respectively arranged at two ends in the third housing 123; a first rotating arm 142 and a second rotating arm 143 are respectively disposed at both sides of the third housing 123; when the first housing 121 and the second housing 122 move towards each other by the rotation of the first rotating arm 142 and the second rotating arm 143, respectively, the first screen support plate 131 and the second screen support plate 132 can be driven to rotate correspondingly; when the respective sides of the first screen support plate 131 and the second screen support plate 132 rotate correspondingly, the respective other sides of the first screen support plate 131 and the second screen support plate 132 slide in the track grooves 161 of the screen support plate track blocks 160 disposed in the first housing 121 and the second housing 122, respectively, so that the first screen support plate 131 and the second screen support plate 132 sink, so that the foldable screen 110 can be located inside the first housing 121 and the second housing 122 when the first housing 121 and the second housing 122 move toward each other.

Specifically, the terminal device may be an electronic device such as a smart phone, a tablet computer, or a display screen. The terminal device includes a first housing 121 and a second housing 122 disposed symmetrically to each other. A third housing 123 is provided at an opposite side between the first housing 121 and the second housing 122. The terminal device further comprises a foldable screen 110. In particular, the screen 110 is a flexible screen. The screen 110 may be unfolded or folded along with the first housing 121 and the second housing 122. A first screen support plate 131 and a second screen support plate 132 are provided in the first housing 121 and the second housing 122, respectively. The first screen support plate 131 and the second screen support plate 132 are respectively used for bearing corresponding partial screens 110. As shown in fig. 1, 2 and 3, when the terminal device is in the unfolded state, the screen 110 is attached to the first screen support plate 131 and the second screen support plate 132. The first screen supporting plate 131 and the second screen supporting plate 132 are fixed to the first housing 121 and the second housing 122, respectively, so as to ensure that the screen 110 is well supported on a plane when the screen 110 is unfolded.

As shown in fig. 4, the terminal device further includes a hinge mechanism 140. The rotation shaft mechanism 140 includes a gear box 141, a pair of first rotation arms 142, and a pair of second rotation arms 143. Wherein the gear box 141 is disposed in the third housing 123, as shown in fig. 5. In this embodiment, the number of the gear boxes 141 is two, and the two gear boxes are respectively disposed at two ends of the third housing 123 and symmetrically disposed, as shown in fig. 4. The pair of first rotating arms 142 is disposed at one side of the third housing 123, and the pair of second rotating arms 143 is disposed at the other side of the third housing 123. As shown in fig. 4, in the present embodiment, the first rotating arm 142 and the second rotating arm 143 are also symmetrically disposed to each other, so as to ensure a synchronous action when the first casing 121 and the second casing 122 are unfolded or folded.

As shown in fig. 4 to 6, in the present embodiment, one end of the first rotation arm 142 is connected to the first housing 121, and the other end of the first rotation arm 142 is connected to the gear box 141. One end of the second rotating arm 143 is connected to the second housing 122, and the other end of the second rotating arm 143 is connected to the gear box 141. When the first housing 121 and the second housing 122 move towards each other by the rotation of the first rotating arm 142 and the second rotating arm 143, respectively, the mechanism of the rotating shaft mechanism 140 moves to drive the first screen supporting plate 131 and the second screen supporting plate 132 to rotate correspondingly, and the foldable screen 110 supported by the first screen supporting plate 131 and the second screen supporting plate 132 is also bent accordingly. When the first housing 121 and the second housing 122 are closed with each other, the screen 110 can form a U-shaped structure having an R-angle.

As shown in fig. 5, in the present embodiment, the gear box 141 includes a gear box 155, a first gear 151, and a second gear 152. One ends of the first gear 151 and the second gear 152 are respectively connected to the first rotating arm 142 and the second rotating arm 143, and the other ends of the first gear 151 and the second gear 152 are respectively connected to the gear box 155. Further, the first gear 151 and the second gear 152 each include a tooth portion 191 and a first spindle portion 192. The first rotation shaft portions 192 are provided at both ends of the tooth portion 191. The tooth portion 191 is used to transmit force by meshing with an adjacent gear (the third gear 153 or the fourth gear 154 described below). The first shaft portion 192 functions as a pivot joint, as described below.

The first rotating arm 142 and the second rotating arm 143 are both pivoted to the first rotating shaft 192 and rotate around the first rotating shaft 192. The rotation angle may range from 0 degrees to 90 degrees as shown in fig. 7.

As shown in fig. 5, further, the gear box 141 may further include a third gear 153 and a fourth gear 154. The third gear 153 is engaged with the first gear 151, the fourth gear 154 is engaged with the third gear 153, and the second gear 152 is engaged with the fourth gear 154. Because the centers of the first gear 151 and the second gear 152 of the gear box 141 coincide with the rotation centers of the first rotating arm 142 and the second rotating arm 143, when the first rotating arm 142 rotates, the first gear 151 is automatically driven to rotate, the first gear 151 drives the third gear 153 to rotate, meanwhile, the third gear 153 drives the fourth gear 154 to rotate, the fourth gear 154 drives the second gear 152 to rotate, and the second gear 152 drives the second rotating arm 143 to rotate, so that the first casing 121 and the second casing 122 on the left side and the right side of the terminal device can be rotated and synchronized.

Referring to fig. 4 to 6, in some embodiments of the present application, the first rotating arm 142 and the second rotating arm 143 are respectively connected to the first housing 121 and the second housing 122 by a fastening member.

Specifically, each of the first and second

rotating arms

142 and 143 includes a first rotating part 171 and a second rotating part 172, and the second rotating part 172 is perpendicular to the first rotating part 171. The first rotating arm 142 and the second rotating part 172 of the second rotating arm 143 are each connected to the first housing 121 and the second housing 122 through the fastening members, which may be screws, but are not limited thereto. The first rotating portion 171 of the first rotating arm 142 and the first rotating portion 171 of the second rotating arm 143 are connected to the first gear 151 and the second gear 152, respectively.

Referring to fig. 4, 8 and 9, the terminal device further includes a screen support plate track block 160. In this embodiment, the number of the screen supporting plate track blocks 160 is two, and the screen supporting plate track blocks 160 are respectively disposed in the first housing 121 and the second housing 122. The screen support plate track block 160 is shown as a bar. One side of each of the first screen support plate 131 and the second screen support plate 132 is disposed in the third housing 123 through a second hinge part 180 in the third housing 123, as shown in fig. 10, 11 and 12, and the other side of each of the first screen support plate 131 and the second screen support plate 132 is connected to the screen support plate track block 160, as shown in fig. 4.

Further, in the present embodiment, as shown in fig. 9, the screen support plate track block 160 includes a track groove 161, and the other side of the first screen support plate 131 and the other side of the second screen support plate 132 are sunk by sliding the pin 162 in the track groove 161, specifically, along the track direction of the track groove 161. Wherein the sinking speed is controlled by the trajectory line of the trajectory groove 161. Since the rotation angle of the first screen supporting plate 131 (or the second screen supporting plate 132) around the third housing 123 is constant, the length and the track of the track line of the track groove 161 can control the sinking speed of the first screen supporting plate 131 and the second screen supporting plate 132, thereby ensuring that the rotating shaft rotates and sinks slowly.

As described above, the first screen support plate 131 and the second screen support plate 132 may be sunk downward during the rotation, thereby allowing the foldable screen 110 to be positioned inside the first housing 121 and the second housing 122 after being bent, i.e., hidden inside the first housing 121 and the second housing 122, thereby reducing the thickness of the entire terminal device. That is, when the hinge mechanism 140 of the present application is employed, it is possible to achieve a folding thickness of the entire machine equal to the sum of the thickness of the first housing 121 and the thickness of the second housing 122, whereas the folding thickness of the entire machine is equal to the sum of the thickness of the first housing 121 and the thickness of the second housing 122 and the bending diameter of the screen 110, as in the case of the related art without employing this structure.

Further, in this embodiment, when the first housing 121 and the second housing 122 move toward each other by the rotation of the first rotating arm 142 and the second rotating arm 143, respectively, one side of each of the first screen support plate 131 and the second screen support plate 132 rotates around the second rotating shaft 180, and the other side of each of the first screen support plate 131 and the second screen support plate 132 slides along the track line direction of the track groove 161 to sink, so as to avoid the bending space of the foldable screen 110, and the foldable screen 110 can be located inside the first housing 121 and the second housing 122. When the terminal device is closed, the screen 110 is fixed to the first screen supporting plate 131 and the second screen supporting plate 132 in a U-shaped bent manner, as shown in fig. 13, 14 and 15. At this time, the first screen supporting plate 131 and the second screen supporting plate 132 are fixed on the first housing 121 and the second housing 122, so that the flexibility of the screen 110 and the complete closing of the first housing 121 and the second housing 122 are ensured, thereby achieving the effects of protecting the screen 110, reducing the thickness of the terminal device when folded, and beautifying the appearance.

The embodiment of the present application provides a terminal device, which moves through the mechanism of the rotating shaft mechanism 140, so that the screen 110 sinks slowly as the first rotating shaft part 192 and the second rotating shaft part 180 in the rotating shaft mechanism 140 rotate, and when the terminal device is folded to zero degree, the first housing 121 and the second housing 122 of the terminal device are completely closed, and the screen 110 forms a U-shaped structure with an R angle, thereby perfectly solving the bending problem of the screen 110 and the protection problem of the screen 110, and simultaneously reducing the thickness of the terminal device when being folded.
