Description

Technical Field

[0001] The present application relates to the technical field of display devices, and in particular to a hinge mechanism and a smart terminal. Background Art

[0002] Folding phones generally have a structure with two side shells and hinges, and the hinges are the core mechanism for realizing the folding of the device. When a folding phone falls in a closed state, the parts inside the hinge shift against each other, causing the bending area of ​​the flexible display to deform severely. When the hinge decoration falls downward and lands on the ground, the impact energy wave is directly transmitted to the bending area of ​​the flexible display through the hinge, causing the film layer, glue layer and pane l layer to fail. For actual user scenarios, when the drop height increases, such as a drop height of 1.2m, the risk of damage to the water drop area of ​​the closed folding screen is further increased, which greatly affects the service life of the folding phone.

[0003] The current hinge design lacks an effective top-up mechanism. The existing hinge mechanism is to align the movable door panel parts with the hinge base. When the closed folding mobile phone falls, the shock wave acts on the hinge base, and the door panel and the hinge base are aligned with each other to reduce the relative displacement between the two. The door panel is connected to the bottom of the flexible display screen by adhesive or glue, so as to prevent the bending area of ​​the flexible display screen from colliding with the surrounding structural parts due to large displacement and deformation of the floating plate, and minimize the risk of damage and screen breakage in the bending area of ​​the flexible display screen.

[0004] In the process of conceiving and realizing this application, the inventors found that there are at least the following problems: First: Under the strong demand for weight reduction of folding mobile phones, in order to achieve effective structural alignment between the door panel and the hinge base, the material of the floating plate must be a metal material with high strength and high density, which will inevitably increase the overall weight of the hinge, which is contrary to weight reduction. Second: Under this structural method, the overall displacement of the door panel and the screen in the screen space caused by the impact energy of the fall cannot be completely avoided, and there is still a risk of the bending area of ​​the screen colliding with nearby structural parts. Third: The alignment structure of the floating plate and the hinge base in the closed state has the risk of parts deformation and jamming after multiple unfolding and closing.

[0005] The preceding description is intended to provide general background information and does not necessarily constitute prior art. Utility Model Content

The touch panel 1071 may include two parts: a touch detection device and a touch controller. Optionally, the touch detection device detects the user's touch orientation, detects the signal brought by the touch operation, and transmits the signal to the touch controller; the touch controller receives the touch information from the touch detection device, converts it into the touch point coordinates, and then sends it to the processor 110, and can receive and execute commands sent by the processor 110.

Figure 1 In the figure, the touch panel 1071 and the display panel 1061 are used as two independent components to realize the input and output functions of the smart terminal.

[0068] Based on the above-mentioned smart terminal hardware structure and communication network system, various embodiments of the present application are proposed.

[0069] First embodiment

[0070] Figure 3 FIG. 1 is a cross-sectional structural diagram of the hinge mechanism of the first embodiment of the present application in a closed state. Figure 3 As shown, the hinge mechanism includes a base 12, at least one swing arm 13, at least one shell 14 and at least one clamping structure 15, one end of the swing arm 13 is rotatably connected to the base 12, the other end of the swing arm 13 is linked to the shell 14, a joint portion is provided on the shell 14, the clamping structure 15 is movably connected to the base 12, and the clamping structure 15 is provided with a clamping portion 151. When the swing arm 13 and the shell 14 are rotated to a closed state, the swing arm 13 can push the clamping structure 15 to make the clamping portion 151 dock with the joint portion. In this embodiment, the swing arm 13 is linked to the shell 14 through a floating plate, that is, when the shell 14 rotates relative to the base 12, it can drive the swing arm 13 to rotate synchronously.

[0071] When the hinge mechanism of the present application is in a closed state, the clamping portion 151 is docked with the joint portion, so that the base 12 and the shell 14 are facing each other. The falling shock wave can be dispersed from the base 12 to the shell 14, which can not only reduce the displacement of the parts inside the hinge and improve the user experience of the product, but also remove the strength, material and other restrictions of the movable floating plate, which is beneficial to reduce the weight of the hinge mechanism.

[0072] Optionally, Figure 4 is a cross-sectional structural schematic diagram of the base, swing arm and clamping structure of the present application in an unfolded state, Figure 5 : is a bottom view of the base, swing arm and clamping structure of the present application. Figure 3 , Figure 4 and Figure 5 As shown, the base 12 is provided with a rotating groove 301 and a through hole 302. The through hole 302 is connected to the rotating groove 301 and passes through the outer wall of the base 12. The swing arm 13 is at least partially arranged in the rotating groove 301. The clamping structure 15 is at least partially installed in the through hole 302. The clamping part 151 passes through the through hole 302 and docks with the joint part.

In this embodiment, the first elastic member 154 may be sleeved on the clamping rod 152, or the first elastic member 154 may not be sleeved on the clamping rod 152.

When the swing arm 13 and the housing 14 rotate to the unfolded state, the elastic force of the first elastic member 154 is greater than the magnetic attraction of the first magnetic block 143 and the second magnetic block 155; the elastic restoring force of the first elastic member 154 can overcome the magnetic attraction of the first magnetic block 143 and the second magnetic block 155 to drive the clamping portion 151 to move out of the hole 304. In this embodiment, the magnetic attraction of the first magnetic block 143 and the second magnetic block 155 together can make the clamping portion 151 more stable, ensuring that the falling shock wave can be stably dispersed from the base 12 to the housing 14.

In this embodiment, the first guiding slope 3041 is provided on the inner wall of the hole 304, and the second guiding slope 1511 is provided on the clamping portion 151, so that the clamping portion 151 is more easily inserted into the hole 304 and is more easily detached from the hole 304.
