[0002] With the development of science and technology, the technology of flexible display screens has been developed. Therefore, in order to realize the convenience of electronic devices, foldable electronic devices have emerged. Foldable electronic devices can have a large display area and good portability. Foldable electronic devices achieve relative folding and unfolding between two adjacent shells through a hinge mechanism, wherein the hinge mechanism includes a connector, a swing arm and a door panel. The door panel and the swing arm are connected to the shell through a connector, and the connector is fixed to the shell with screws. In order to ensure the waterproof performance of the electronic device, each screw needs to be waterproofed, such as applying glue to the head of the screw for waterproofing or setting a sealing rubber ring on the screw to achieve waterproofing. Once a screw is not waterproofed well, the waterproof design of the electronic device may fail. Summary of the invention

[0003] The present application provides a housing, a housing assembly and an electronic device to solve the technical problem that the waterproof design on the screws connecting the connecting piece of the rotating shaft mechanism and the housing is prone to waterproof failure.

[0008] By adopting the above scheme, after the first frame portion is connected to the bottom plate portion, the bending strength and bearing capacity of the first frame portion are enhanced. After the connecting portion is set on the first frame portion, the connecting portion serves as a part of the shell, so that the hinge mechanism can be directly movably connected to the shell, thereby eliminating the screws used to connect the hinge mechanism and the shell. After the electronic device is waterproofed, it is beneficial to ensure the stability of the waterproof performance.

[0009] In some implementations, the connection structure includes at least one of a hinge shaft hole, a sliding groove, and a rotating arc surface.

[0010] By adopting the above solution, the housing can adapt to different components on the rotating shaft mechanism, so that different components on the rotating shaft mechanism are movably connected with the housing in a corresponding manner.

[0023] The center of the circle corresponding to the first arc is concentrically arranged with the center of the circle corresponding to the second arc;

[0024] The second setting plane is perpendicular to the length direction of the first frame portion.

[0035] The main body and the second reinforcement block are an integral structure. The second reinforcement blocks are respectively arranged on two opposite sides of the main body in the length direction of the first frame portion, and the second reinforcement blocks are connected to the second side surface.

After the connecting portion is set on the first frame portion, the connecting portion serves as a part of the shell, so that the door panel and the first swing arm of the hinge mechanism can be directly and movably connected to the shell respectively, thereby eliminating the screws used to connect the hinge mechanism and the shell, and thus after the electronic equipment is waterproofed, it is beneficial to ensure the stability of the waterproof performance.

[0051] In some implementations, the door panel has a second convex curved surface and a second concave curved surface; the second convex curved surface and the second concave curved surface are spaced apart in the length direction of the door panel.

[0105] In one or more embodiments, the present application provides an electronic device, which may be a foldable electronic device; the electronic device includes a display screen assembly and a shell assembly, and the display screen assembly is connected to the shell 100. The shell assembly includes a shell 100 and a hinge mechanism 200, and the number of shells 100 is two, and the two shells 100 can be symmetrically arranged with the center line of the hinge mechanism 200 as the symmetry axis; the center line of the hinge mechanism 200 is also parallel to the axial direction of the hinge mechanism 200; the two shells 100 are respectively connected to the hinge mechanism 200, and the two shells 100 can rotate relative to each other through the hinge mechanism 200. Exemplary electronic devices may be mobile phones, tablet computers, notebooks, or e-readers. Foldable electronic devices are not limited to electronic devices with foldable displays, such as mobile phones, but may also be electronic devices with foldable or unfoldable display screens and keyboards, such as notebooks. It should be noted that the two shells 100 may also be an asymmetric structure.

[0106] In the embodiment of the present application, taking the electronic device as a mobile phone as an example, the display screen assembly includes a flexible display screen 300, and the flexible display screen 300 is respectively connected to one side of the two housings 100. The housing 100 can be a middle frame of the mobile phone.

[0107] For ease of description, the length direction of the foldable electronic device is defined as the X direction, the width direction of the foldable electronic device is defined as the Y direction, and the thickness direction of the foldable electronic device is defined as the Z direction. The X direction, the Y direction, and the Z direction are perpendicular to each other.

[0108] Figure 1 The foldable electronic device is shown in a folded state. Figure 2 The foldable electronic device is shown in a semi-expanded state. Figure 3 The foldable electronic device is shown in an unfolded state. Figure 2 The unfolding angle α of the foldable electronic device shown is 90 degrees. Figure 3 The unfolding angle β of the foldable electronic device shown is 180 degrees.

[0109] It should be noted that the angles illustrated in the embodiments of the present application are allowed to have slight deviations. Figure 2 The unfolding angle α of the foldable electronic device shown is 90 degrees, which means that α can be 90 degrees, or approximately 90 degrees, such as 80 degrees, 85 degrees, 95 degrees or 100 degrees. Figure 3 The unfolding angle β of the foldable electronic device shown is 180 degrees, which means that β can be 180 degrees, or approximately 180 degrees, such as 170 degrees, 175 degrees, 185 degrees, and 190 degrees, etc. The angles described below can be understood in the same way.

[0110] See also Figure 4 , Figure 4 yes Figure 3The schematic diagram of the exploded structure of the electronic device shown in the figure; two housings 100 are respectively installed on both sides of the rotating shaft mechanism 200 along the Y direction, and the flexible display screen 300 includes a first part 301, a second part 302 and a foldable part 303. The foldable part 303 is located between the first part 301 and the second part 302, and the foldable part 303 can be bent along the X direction. The first part 301, the second part 302 and the foldable part 303 together constitute a display screen. In this embodiment, the flexible display screen 300 can be: an organic light-emitting diode (OLED) display screen, an active-matrix organic light-emitting diode or an active-matrix organic light-emitting diode (AMOLED) display screen, a mini organic light-emitting diode (mini organic light-emitting diode) display screen, a micro organic light-emitting diode (micro organic light-emitting diode) display screen, a micro organic light-emitting diode (micro organic light-emitting diode) display screen or a quantum dot light emitting diode (quantum dotlight emitting diodes, QLED) display screen.

[0111] The flexible display screen 300 is folded by bringing the two shells 100 relatively close to each other, so that the foldable electronic device can be folded. When the foldable electronic device is in a folded state, the foldable portion 303 of the flexible display screen 300 is bent, and the first portion 301 and the second portion 302 are arranged relatively. At this time, the flexible display screen 300 is between the two shells 100, which can greatly reduce the probability of damage to the display screen and achieve effective protection of the flexible display screen 300. It should be noted that the foldable electronic device can be an inward-folding electronic device or an outward-folding electronic device. An inward-folding electronic device is one in which the flexible display screen is located on the inner side of the electronic device after being folded; an outward-folding electronic device is one in which at least part of the flexible display screen is located on the outer side of the electronic device after being folded.

[0112] Please also read Figure 1 and Figure 2 , the two shells 100 rotate relative to each other through the hinge mechanism 200, and the two shells 100 move away from each other to drive the flexible display screen 300 to unfold, so that the foldable electronic device is in a semi-expanded state. When the foldable electronic device is in a semi-expanded state, the shells 100 and the shells 100 unfold to an angle of α, the first part 301 and the second part 302 unfold relatively, and drive the foldable part 303 to unfold. At this time, the angle between the first part 301 and the second part 302 is α.

[0113] Please also read Figure 2 and Figure 3 The two housings 100 rotate relative to each other through the hinge mechanism 200, and the display screen is further unfolded by the relative distance between the two housings 100 until the foldable electronic device is flattened. The hinge mechanism 200 has a damping mechanism to achieve the opening and closing feel and state maintenance during the rotation process.

[0114] When the electronic device is in a flattened state, the angle between the two housings 100 is β. The foldable portion 303 is unfolded, and the first portion 301 and the second portion 302 are relatively unfolded. At this time, the angles between the first portion 301, the second portion 302 and the foldable portion 303 are all β, and the display screen has a large display area, realizing a large-screen display of the foldable electronic device, and improving the user experience.

[0115] It should be noted that the angle α and the angle β are both the angles between the two shells 100, which are only used to distinguish the different angles between the two shells 100 of the foldable electronic device in different states. The angle α refers to the angle between the two shells 100 when the foldable electronic device is in a semi-expanded state; the angle β refers to the angle between the two shells 100 when the foldable electronic device is in an expanded state.

[0116] See also Figure 4 As shown, the housing 100 includes a bottom plate portion 102 , the bottom plate has two opposite plate surfaces, and the flexible display screen 300 is installed on one of the plate surfaces of the bottom plate portion 102 .

[0118] It should be noted that, in some other possible embodiments, the display screen assembly may also include a rigid display screen, so that in addition to displaying content on the flexible display screen 300, the electronic device can also display content through the rigid display screen after being folded; for the shell 100, a rigid display screen or an outer shell cover 400 may be installed on the other side opposite to the shell 100; since there are two shells 100 in the shell assembly, it may be that: the outer shell cover 400 is installed on the other side opposite to one of the shells 100, and the rigid display screen is installed on the other side opposite to the other shell 100; or, rigid display screens are installed on the other sides opposite to the two shells 100.
