Description

Technical Field

[0001] The present application relates to the field of electronic devices, and more specifically, to a foldable device. Background Art

[0002] As flexible organic light-emitting diode (OLED) technology matures, devices with foldable screens (e.g., foldable mobile phones) will become the mainstream trend in the next few years.

[0003] In foldable devices, a hinge mechanism is used to achieve the unfolding and folding of the screen. However, the hinge mechanism of some foldable devices is partially exposed, resulting in the overall appearance of the device being incomplete and unsightly. In addition, foreign matter can easily enter the interior of the device, thereby affecting the device's waterproof and dustproof performance.

[0004] Based on this, it is necessary to provide a device that, in addition to realizing the folding function of the device, can also realize the integrity and aesthetics of the device's appearance, as well as realize the waterproof and dustproof performance of the device. Summary of the invention

[0005] The present application provides a folding device, including a hinge mechanism, two housings and a screen. The hinge mechanism of the folding device realizes the folding function of the device. The hinge mechanism includes a main shaft assembly and two hinge assemblies. The hinge assembly includes a swing rod, a sliding cover plate and a slider. The swing rod is rotatably connected to the main shaft assembly and slidably connected to the slider. The sliding cover plate is slidably connected to the main shaft assembly and connected to the swing rod. During the rotation of the swing rod relative to the main shaft assembly, the swing rod can drive the slider to not only rotate relative to the main shaft assembly but also slide relative to the swing rod. The swing rod can drive the sliding cover plate to slide on the main shaft assembly. By controlling the movement of the sliding cover plate, the housing and the slider through the swing rod, the folding device can form a continuous and complete shell in any state. This continuous and complete shell can not only realize the integrity and aesthetics of the appearance of the device, but also can cover the internal structure of the folding device to realize the waterproof and dustproof performance of the device.

[0006] In a first aspect, a folding device is provided, comprising: a hinge mechanism, two housings, and a screen, wherein the two housings and the screen are arranged on both sides of the hinge mechanism;

[0007] The hinge mechanism includes: a main shaft assembly, two hinge assemblies arranged on both sides of the main shaft assembly, one hinge assembly corresponds to one housing, and the hinge assembly includes: a swing rod, a sliding cover plate, and a sliding block, wherein:

[0008] The swing rod and the slider are sequentially arranged along the axial direction of the spindle assembly, the swing rod is rotatably connected to the spindle assembly, and the slider is slidably connected to the swing rod and fixedly connected to the housing;

[0009] The sliding cover plate is arranged along the axial direction of the main shaft assembly, and the sliding cover plate is slidably connected to the main shaft assembly and connected to the swing rod;

[0010] The spindle assembly is formed with a receiving cavity for receiving the sliding cover plate;

[0011] When the folding device is in a folded state, the sliding cover is located between the main shaft assembly and the outer shell, so that the two sliding cover plates, the two outer shells and the main shaft assembly form a shell of the folding device. During the process of the folding device being converted from a folded state to an unfolded state, the rocker arm can rotate relative to the main shaft assembly, and the rocker arm can drive the sliding cover to slide in a direction close to the main shaft assembly, and the sliding cover is accommodated in the accommodating cavity, and the rocker arm can drive the outer shell to move in a direction close to the main shaft assembly through the slider, so that the two outer shells move to the outside of the main shaft assembly.

[0012] The folding device provided in the embodiment of the present application has a hinge mechanism that realizes the folding function of the device. The two shells and the screen of the folding device are respectively on both sides of the hinge mechanism. The hinge mechanism includes a main shaft assembly and two hinge assemblies. The hinge assembly includes a rocker arm, a sliding cover plate and a slider. The rocker arm is rotatably connected to the main shaft assembly and slidably connected to the slider. In this way, during the rotation of the rocker arm relative to the main shaft, the slider can be driven not only to rotate relative to the main shaft assembly but also to slide relative to the rocker arm, so as to adjust the width of the hinge mechanism to adapt to the deformation of the screen. The sliding cover plate is slidably connected to the main shaft assembly and to the rocker arm. During the rotation of the rocker arm relative to the main shaft assembly, the sliding cover plate can be driven to slide on the main shaft assembly. The movement of the sliding cover, the shell and the slider is controlled by the swing rod. When the folding device is in the folded state, the sliding cover slides to the position between the main shaft assembly and the shell, so that the two sliding cover plates, the two shells and the main shaft assembly form a continuous and complete shell of the folding device. In the process of the folding device being converted from the folded state to the unfolded state, the sliding cover slides close to the main shaft assembly, the shell moves close to the main shaft assembly, and the two shells approach each other and can move to the outside of the main shaft assembly to finally cover the main shaft assembly. When the folding device is in a semi-expanded state at a certain angle, the two shells and the main shaft assembly can form a continuous and complete shell of the folding device. When the folding device is in a fully unfolded state, the two shells can form a continuous and complete shell of the folding device. Therefore, by controlling the movement of the sliding cover, the shell and the slider through the swing rod, in addition to realizing the folding function of the folding device, the folding device can also form a continuous and complete shell in any state. This continuous and complete shell can not only realize the integrity and aesthetics of the appearance of the device, but also cover the internal structure of the folding device to realize the waterproof and dustproof performance of the device.

The connecting rod is rotationally connected to the main shaft assembly and connected to the sliding cover plate. During the rotation of the rocker arm relative to the main shaft assembly, the rocker arm can drive the sliding cover plate to slide on the main shaft assembly through the connecting rod.

[0014] The folding device provided in the embodiment of the present application realizes the sliding connection between the sliding cover and the rocker arm through a connecting rod, which is easy to realize in structure. Moreover, the sliding connection between the rocker arm and the sliding cover can make the rotation radius of the rocker arm relative to the main shaft assembly different from the rotation radius of the sliding cover relative to the main shaft assembly. The rotation radius of the sliding cover is smaller than the rotation radius of the rocker arm. This design can reduce the radial dimension of the main shaft assembly, reduce the overall size of the device, and improve user experience.

[0015] Optionally, a first sliding groove is provided on the connecting rod, and a first connecting member slidable in the first sliding groove is provided on the rocker arm.

During the opening and closing process of the folding device 10, under the action of the hinge mechanism 100, the two housings 200 move closer to or farther from each other, so as to facilitate the deformation of the screen 300. When the folding device 10 is in the folded state, the distance between the two housings 200 is the farthest, forming a Figure 1 The empty area shown is the screen area 101 of the folding device 10. When the folding device 10 is in the unfolded state, the distance between the two shells 200 is the shortest. Ideally, the angle between the two shells 200 is substantially 180 degrees, and the screen 300 is substantially in the same position as shown in FIG. Figure 2 The horizontal state shown.

[0049] Continue to refer Figure 1 to Figure 2 The hinge mechanism 100 includes a main shaft assembly 110 and two hinge assemblies, and the hinge assembly includes a swing rod 120, a slider 130 and a sliding cover plate 140.

For example, the angle between the two shells 200 is approximately 180 degrees, the distance between the two shells 200 is the shortest, the two shells 200 move to the outside of the main shaft assembly 110 and cover the main shaft assembly 110, the two shells 200 are docked, and the two shells 200 form a continuous and complete shell of the folding device 10, which can not only realize the integrity and aesthetics of the appearance of the device, but also this continuous and complete shell can cover the internal structure of the folding device and realize the waterproof and dustproof performance of the device.

[0087] In summary, it can be seen that by controlling the movement of the sliding cover 140, the shell 200, and the slider 130 through the rocker rod 120, in addition to realizing the folding function of the folding device, the folding device can also form a continuous and complete shell in any state, which not only realizes the integrity and aesthetics of the device appearance, but also such a continuous and complete shell can cover the internal structure of the folding device, thereby realizing the waterproof and dustproof performance of the device.

[0088] The folding device provided in the embodiment of the present application has a hinge mechanism that realizes the folding function of the device. The two shells and the screen of the folding device are respectively on both sides of the hinge mechanism. The hinge mechanism includes a main shaft assembly and two hinge assemblies. The hinge assembly includes a rocker arm, a sliding cover plate and a slider. The rocker arm is rotatably connected to the main shaft assembly and slidably connected to the slider. In this way, during the rotation of the rocker arm relative to the main shaft, the slider can be driven not only to rotate relative to the main shaft assembly but also to slide relative to the rocker arm, so as to adjust the width of the hinge mechanism to adapt to the deformation of the screen. The sliding cover plate is slidably connected to the main shaft assembly and to the rocker arm. During the rotation of the rocker arm relative to the main shaft assembly, the sliding cover plate can be driven to slide on the main shaft assembly. The movement of the sliding cover, the shell and the slider is controlled by the swing rod. When the folding device is in the folded state, the sliding cover slides to the position between the main shaft assembly and the shell, so that the two sliding cover plates, the two shells and the main shaft assembly form a continuous and complete shell of the folding device. In the process of the folding device being converted from the folded state to the unfolded state, the sliding cover slides close to the main shaft assembly, the shell moves close to the main shaft assembly, and the two shells approach each other and can move to the outside of the main shaft assembly to finally cover the main shaft assembly. When the folding device is in a semi-expanded state at a certain angle, the two shells and the main shaft assembly can form a continuous and complete shell of the folding device. When the folding device is in a fully unfolded state, the two shells can form a continuous and complete shell of the folding device. Therefore, by controlling the movement of the sliding cover, the shell and the slider through the swing rod, in addition to realizing the folding function of the folding device, the folding device can also form a continuous and complete shell in any state. This continuous and complete shell can not only realize the integrity and aesthetics of the appearance of the device, but also cover the internal structure of the folding device to realize the waterproof and dustproof performance of the device.
