Description

Housing, housing components and electronic equipment

[0001] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office on July 26, 2023, with application number 202310944928.4 and application name “Housing, housing assembly and electronic device”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the technical field of electronic equipment, and in particular to a housing, a housing assembly, and an electronic device. Background Art

[0003] With the development of science and technology, the technology of flexible display screens has been developed. Therefore, in order to achieve 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 putting a sealing rubber ring on the screw to achieve waterproofing. Once the waterproofing of a screw is not done well, the waterproof design of the electronic device may fail.

After the connecting portion is provided on the first frame portion, the connecting portion serves as a part of the shell, so that the rotating shaft mechanism can be directly movably connected to the shell, thereby eliminating the screws used to connect the rotating shaft mechanism and the shell. Therefore, after the electronic device is waterproofed, it is helpful to ensure the stability of the waterproof performance.

[0025] The center of the circle corresponding to the first arc is concentric with the center of the circle corresponding to the second arc;

DETAILED DESCRIPTION

[0099] In order to make the objectives, technical solutions and advantages of this application clearer, the implementation methods of this application will be further described in detail below with reference to the accompanying drawings.

[0100] It should be understood that the “multiple” mentioned in this application refers to two or more.

Those skilled in the art can understand that words such as “first” and “second” do not limit the quantity and execution order, and words such as “first” and “second” do not necessarily limit them to be different.

[0101] Please refer to Figures 1 to 3. Figure 1 is a structural schematic diagram of the electronic device provided in an embodiment of the present application in a folded state, Figure 2 is a structural schematic diagram of the electronic device provided in an embodiment of the present application in a semi-expanded state, and Figure 3 is a structural schematic diagram of the electronic device provided in an embodiment of the present application in an expanded state.

[0102] 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. There are two shells 100, 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 can also be electronic devices with a display screen and a keyboard that can be folded or unfolded, such as notebooks. It should be noted that the two shells 100 can also be an asymmetric structure.

[0103] In the embodiment of the present application, taking the electronic device as a mobile phone as an example, the display assembly includes a flexible display 300, and the flexible display 300 is respectively connected to one side of the two housings 100. The housing 100 can be the middle frame of the mobile phone.

[0104] 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, Y direction, and Z direction are perpendicular to each other.

[0105] The foldable electronic device shown in Figure 1 is in a folded state, the foldable electronic device shown in Figure 2 is in a semi-expanded state, and the foldable electronic device shown in Figure 3 is in an expanded state. The expansion angle α of the foldable electronic device shown in Figure 2 is 90 degrees, and the expansion angle β of the foldable electronic device shown in Figure 3 is 180 degrees.

[0106] It should be noted that the angles illustrated in the embodiments of the present application are allowed to have slight deviations. For example, the unfolding angle α of the foldable electronic device shown in Figure 2 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. The unfolding angle β of the foldable electronic device shown in Figure 3 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. The angles illustrated in the following text can be understood in the same way.

[0107] Please refer to Figure 4, which is a schematic diagram of the exploded structure of the electronic device shown in Figure 3. Two housings 100 are respectively mounted on either side of the hinge mechanism 200 along the Y direction. The flexible display 300 includes a first portion 301, a second portion 302, and a foldable portion 303. The foldable portion 303 is located between the first portion 301 and the second portion 302 and can bend along the X direction. The first portion 301, the second portion 302, and the foldable portion 303 together constitute the display. In this embodiment, the flexible display 300 can be an organic light-emitting diode (OLED) display, an active-matrix organic light-emitting diode (AMOLED) display, a mini organic light-emitting diode (OLED) display, a micro organic light-emitting diode (OLED) display, a micro organic light-emitting diode (OLED) display, or a quantum dot light-emitting diode (QLED) display.

[0108] The flexible display screen 300 is folded by bringing the two shells 100 closer together, 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 relative to each other. 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 for 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 folding; 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 folding.

[0109] Referring to Figures 1 and 2 , the two housings 100 rotate relative to each other via the hinge mechanism 200, moving the two housings 100 further apart, driving the flexible display 300 to unfold, thereby allowing the foldable electronic device to move from a folded to a semi-expanded state. When the foldable electronic device is in the semi-expanded state, the housings 100 and 100 unfold to an angle α, and the first portion 301 and the second portion 302 unfold relative to each other, driving the foldable portion 303 to unfold. At this point, the angle between the first portion 301 and the second portion 302 is α.

[0110] Referring to Figures 2 and 3 , the two housings 100 rotate relative to each other via a hinge mechanism 200. This movement of the two housings 100 further expands the display screen until the foldable electronic device is flattened. The hinge mechanism 200 includes a damping mechanism to ensure a smooth opening and closing motion and maintain a stable state.

[0111] When the electronic device is flattened, the angle between the two housings 100 is β. The foldable portion 303 is unfolded, and the first portion 301 and second portion 302 are relatively unfolded. At this point, the angles β between the first portion 301, the second portion 302, and the foldable portion 303 are all β. This allows the display screen to have a large display area, enabling large-screen display for the foldable electronic device and improving the user experience.

[0112] It should be noted that angles α and β are both the angles between the two housings 100. These angles are used to distinguish between the angles between the two housings 100 in different states of the foldable electronic device. Angle α refers to the angle between the two housings 100 when the foldable electronic device is in the semi-expanded state, while angle β refers to the angle between the two housings 100 when the foldable electronic device is in the expanded state.

[0113] 4 , the housing 100 includes a bottom plate portion 102 having two opposite surfaces. The flexible display screen 300 is mounted on one of the surfaces of the bottom plate portion 102 .

[0114] 5 and 6 , FIG5 is a schematic structural diagram of the electronic device provided in an embodiment of the present application in another perspective in the third state, and FIG6 is a schematic decomposed structural diagram of the electronic device shown in FIG5 ; in some embodiments, the shell 100 has a accommodating cavity 107; the shell assembly may further include an outer shell cover 400, which is fixedly connected to the shell 100; illustratively, the outer shell cover 400 covers the accommodating cavity 107, and the outer shell cover 400 is spaced apart from the bottom plate portion 102, and the outer shell cover 400 is opposite to the other plate surface of the bottom plate portion 102, and the other plate surface of the bottom plate portion 102 forms the inner cavity bottom of the accommodating cavity 107; one of the plate surfaces of the bottom plate portion 102 faces away from the outer shell cover 400.

[0115] 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 can be installed on the other side opposite to the shell 100; since there are two shells 100 in the shell assembly, it can be: 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.

[0116] 7 and 8 , FIG7 is a schematic structural diagram of an electronic device in the related art, and FIG8 is a schematic partial structural diagram of the electronic device shown in FIG7 , and FIG8 specifically shows the connection relationship between the connector 20 and the housing 10. In the related art, the foldable electronic device realizes the relative folding and unfolding between two adjacent device housings 10 through a hinge mechanism, wherein the hinge mechanism includes a connector 20, a swing arm 21 and a door panel, and the door panel and the swing arm 21 are connected to the device housing 10 through the connector 20. The connector 20 is fixedly connected to the connecting ear 23 extending from the device housing 10 by a screw 22, and a large number of screws 22 are fixed between the connector 20 and the device housing 10; and in order to ensure the waterproof performance of the electronic device, each screw 22 needs to be waterproofed, for example, in the screw 22 The head of the electronic device is waterproofed by applying glue or a sealing rubber ring is installed on the screw 22 to achieve waterproofing. After waterproofing, an airtightness test is required. Once a screw 22 is not waterproofed, the waterproof design of the electronic device may fail, and the yield after waterproofing is low. Moreover, since each screw 22 needs to be waterproofed, the cost is relatively high. In addition, since the connector 20 and the device housing 10 need to be fixedly connected by screws 22, screw holes need to be opened on the connector 20. In this way, the connector 20 needs to have a certain width in the width direction of the foldable electronic device. As the thickness of the foldable electronic device gradually decreases, the width of the connector 20 on the foldable electronic device also needs to be reduced, thereby increasing the risk of failure of the connection between the hinge mechanism and the device housing 10.

[0117] To this end, an embodiment of the present application provides a housing 100 to solve at least one problem in the above-mentioned related art; the housing 100 provided in the embodiment of the present application is explained in detail below.

[0118] As shown in Figures 9 and 10, Figure 9 is a schematic diagram of the structure of the housing 100 and the rotating shaft mechanism 200 in accordance with an embodiment of the present application; Figure 10 is a schematic diagram of the structure of the housing 100 and the rotating shaft mechanism 200 in accordance with an embodiment of the present application (the door panel is not shown); in the embodiment of the present application, the rotating shaft mechanism 200 includes a base 201, a door panel 202, and a first swing arm 203, which is rotatably connected to the base 201. The door panel 202 and the first swing arm 203 are respectively movably connected to the housing 100, thereby realizing a movable connection between the rotating shaft mechanism 200 and the housing 100. The movable connection can be a high pair or a low pair, specifically a sliding pair, a rotating pair, etc. For example, the specific form of the movable connection between the door panel 202 and the housing 100 can be a rotating connection, that is, a rotating pair; the specific form of the movable connection between the first swing arm 203 and the housing 100 can be a rotating connection or a sliding connection, that is, the first swing arm 203 and the housing 100 can be a rotating pair or a sliding pair.

[0119] As shown in Figures 11 to 12, Figure 11 is a structural schematic diagram of the shell 100 in the embodiment of the present application, and Figure 12 is a structural schematic diagram of the shell 100 from another perspective in the embodiment of the present application. In one or more embodiments, the shell 100 provided by the present application also includes: a first frame portion 101; the first frame portion 101 has a first side surface 104 and a second side surface 105 relative to each other, and the bottom plate portion 102 is connected to the first side surface 104; the second side surface 105 is provided with a connecting portion 103, and the connecting portion 103 protrudes from the second side surface 105; the connecting structure is used to be rotatably connected to the hinge mechanism 200 of the electronic device, that is, after the connecting structure and the hinge mechanism 200 are movably connected, the movable connection between the hinge mechanism 200 and the shell 100 is realized, and the connection structure is rotated relative to the base 201, thereby realizing that the shell 100 can rotate relative to the base 201.

[0120] The shell 100 provided by at least one embodiment of the present application provides support for the first frame portion 101 through the bottom plate portion 102 after the first frame portion 101 is connected to the bottom plate portion 102, so as to enhance the bending strength and bearing capacity of the first frame portion 101. After the connecting portion 103 is set on the first frame portion 101, the connecting portion 103 serves as a part of the shell 100, so that the hinge mechanism 200 can be directly and movably connected to the shell 100, that is, the first swing arm 203, the door panel 202 and other structures of the hinge mechanism 200 can be directly connected to the shell 100, thereby eliminating the large number of screws used in the connection between the hinge mechanism and the device shell 10 in the related art, and eliminating the screw holes; in the present application, the shell 100 and the hinge mechanism 200 are not connected by screws, and after the other parts of the electronic device are waterproofed, it is beneficial to ensure the stability of the waterproof performance. Since screws are no longer used, compared with the related art, the present application eliminates the cost of using screws and the cost of waterproofing the screws. This is beneficial to reducing the cost of waterproofing electronic devices. In addition, since screw holes need to be opened on the connecting member 20 in the related art, and the connection strength between the connecting member 20 and the device housing 10 needs to be ensured, the width of the connecting member 20 in the width direction of the electronic device will be wider. Therefore, compared with the connecting member 20 in the related art that needs to have screw holes, the connecting portion 103 of the present application is a part of the housing 100, and a direct connection with the hinge mechanism 200 is achieved through the connecting portion 103. In this way, there is no need to open screw holes, which saves the width of the screw holes in the width direction of the electronic device in the related art. Therefore, the width of the connecting portion 103 in the Y direction of the present application is smaller than the width of the connecting member 20 in the width direction of the electronic device in the related art. Therefore, when the foldable electronic device is thinned, the present application realizes a direct connection between the hinge mechanism 200 and the housing 100, and is beneficial to ensuring the stability of the connection between the hinge mechanism 200 and the housing 100; furthermore, it is beneficial to reduce the weight of the foldable electronic device.

[0121] In some embodiments, the second side surface 105 can be in the form of a plane; the first frame portion 101 is located at the edge of the bottom plate portion 102; the first frame portion 101 is a linear plate-like structure, the bottom plate portion 102 is a plate-like structure, and the bottom plate portion 102 and the first frame portion 101 are an integral structure, that is, they are made through an integrated molding process, which can enhance the connection strength between the first frame portion 101 and the bottom plate portion 102; and the connecting portion 103 and the first frame portion 101 are an integral structure, that is, they are made through an integrated molding process, which can enhance the connection strength between the first frame portion 101 and the connecting portion 103; the first frame portion 101 has a certain length, height and thickness, and the length direction of the first frame portion 101 is parallel to the axial direction of the rotating shaft mechanism 200, that is, the length direction of the first frame portion 101 is parallel to the X direction, the height direction of the first frame portion 101 is parallel to the Z direction, and the thickness direction of the first frame portion 101 is parallel to the Y direction. It should be noted that, in some other possible embodiments, some reinforcing ribs may be provided on the first side surface 104 to enhance the strength of the first frame portion 101 .

[0122] As shown in Figures 11 and 12, in some embodiments, the housing 100 further includes a second frame portion 106. The second frame portion 106, the first frame portion 101 and the bottom plate portion 102 form a receiving cavity 107. The first side surface 104 faces the receiving cavity 107, and the second side surface 105 faces away from the receiving cavity 107. In this way, the receiving cavity 107 is used to accommodate internal components of the electronic device, such as a motherboard, a speaker, a camera, various sensors and a battery. In one embodiment, the second frame portion 106 is arranged along the edge of the bottom plate portion 102. In this way, after the first frame portion 101 and the second frame portion 106 are respectively arranged along the edge of the bottom plate portion 102, the three can form the receiving cavity 107. The second frame portion 106 and the bottom plate portion 102 are an integral structure, that is, they are made through an integrated molding process, which can enhance the connection strength between the second frame portion 106 and the bottom plate portion 102. The present application omits the connector 20 in the related art, thereby facilitating reduction of the width and thickness of the pivot mechanism 200 and increasing the width of the shell 100 in the Y direction, thereby increasing the capacity of the accommodating cavity 107, thereby facilitating the use of larger batteries to increase the battery capacity.

[0123] As shown in conjunction with Figures 11 and 12, in some embodiments, the second frame portion 106 includes a first sub-frame 108 and two oppositely disposed second sub-frames 109. The lengthwise directions of the two second sub-frames 109 are parallel, and the lengthwise direction of the first sub-frame 108 is parallel to the lengthwise direction of the first frame portion 101. Thus, the second frame portion 106 has a non-linear structure, with the first sub-frame 108, the second sub-frame 109, and the first frame portion 101 forming a substantially rectangular shaped receiving cavity 107. In one embodiment, the longitudinal ends of the first sub-frame 108 are respectively connected to the two second sub-frames 109, and the longitudinal ends of the first frame portion 101 are respectively connected to the two second sub-frames 109. The first sub-frame 108 and the second sub-frame 109 are connected to the bottom plate portion 102, and the first sub-frame 108 and the second sub-frame 109 are each integrally formed with the bottom plate portion 102, i.e., manufactured using an integral molding process, thereby improving the structural stability between the second frame portion 106 and the bottom plate portion 102.

[0124] As shown in Figures 11 and 12 , in some embodiments, the housing 100 further includes a first partitioning internal rib 110 and a second partitioning internal rib 111. The first partitioning internal rib 110 has opposite ends connected to the first sub-frame 108 and the first frame portion 101, respectively. The second partitioning internal rib 111 has opposite ends connected to the first sub-frame 108 and the first frame portion 101, respectively. The portion of the accommodating cavity 107 between the first partitioning internal rib 110 and the second partitioning internal rib 111 is used to accommodate the battery of the electronic device. Thus, the first partitioning internal rib 110 and the second partitioning internal rib 111 can be used to divide the accommodating cavity 107 into different functional areas. Since they are respectively connected to the first frame portion 101, this helps to improve the bending strength and load-bearing capacity of the first frame portion 101. In one embodiment, the first partitioning inner rib 110 and the second partitioning inner rib 111 are respectively connected to the bottom plate portion 102, and the first partitioning inner rib 110 and the second partitioning inner rib 111 are respectively integrated with the bottom plate portion 102, that is, they are made by an integrated molding process, which is conducive to improving the overall structural stability of the shell 100; the shell 100 may also include a third partitioning inner rib 112, the two ends of the third partitioning inner rib 112 are respectively connected to the second sub-frame 109 and the first partitioning inner rib 110, and the third partitioning inner rib 112 can divide the accommodating cavity 107 into more small functional areas; the third partitioning inner rib 112 is an integrated structure with the bottom plate portion 102, that is, it is made by an integrated molding process, thereby improving the structural stability between the third partitioning inner rib 112 and the bottom plate portion 102; the length direction of the third partitioning inner rib 112 is parallel to the length direction of the first frame portion 101; the first partitioning inner rib 110 and the second partitioning inner rib 111 are arranged in parallel, and the length direction of the first partitioning inner rib 110 is parallel to the Y direction.

[0125] As shown in Figures 11 and 12 , in some embodiments, a connecting portion 103 is provided at a location on the second side 105 opposite the connection between the first partitioning inner rib 110 and the first frame portion 101; or / and a connecting portion 103 is provided at a location on the second side 105 opposite the connection between the second partitioning inner rib 111 and the first frame portion 101. This can enhance the structural stability of the connecting portion 103 on the first frame portion 101, thereby ensuring the stability of the movable connection between the hinge mechanism 200 and the housing 100.

[0126] In some embodiments, the housing 100 is manufactured using a CNC (Computerized Numerical Control) process, a 3D printing process, a MIM (Metal Powder Injection Molding Technology) process, an injection molding process, or a die-casting process, which facilitates the realization of an integral structure of the housing 100. The housing 100 can be made of metal or a polymer material, such as an aluminum alloy, an aluminum-magnesium alloy, a titanium alloy, or titanium steel, which helps to improve the strength of the components and facilitates the waterproof design of the foldable electronic device.

[0127] As shown in Figures 12 and 13, Figure 13 is a structural schematic diagram of the shell 100 from another perspective in the embodiment of the present application. Among the two opposite board surfaces of the bottom plate portion 102 in the present application, one of the board surfaces of the bottom plate portion 102 is in a flat form. In this way, the use of the flat board surface is beneficial to improve the flatness of the flexible display screen 300 after installation.

[0128] As shown in Figures 14 and 15, Figure 14 is a cross-sectional view of the housing 100 in an embodiment of the present application, and Figure 15 is a schematic diagram of the partial structure of the housing 100 shown in Figure 14. In some embodiments, there are multiple connecting parts 103, and the multiple connecting parts 103 are distributed along the length direction of the first frame part 101. In this way, the multiple connecting parts 103 can achieve the stability of the rotation of the door panel 202 and facilitate the connection with different swing arms of the rotating shaft mechanism 200. For example, among the multiple connecting parts 103, at least two adjacent connecting parts 103 can be an integrated structure. After such an arrangement, two adjacent connecting parts 103 can be an integrated structure, three adjacent connecting parts 103 can be an integrated structure, four adjacent connecting parts 103 can be an integrated structure, and five adjacent connecting parts 103 can be an integrated structure. It should be noted that in some other possible embodiments, any two adjacent connecting parts 103 are spaced apart.

[0129] As shown in Figure 15, in some embodiments, the connecting portion 103 includes a main body 113 and a reinforcement portion, the main body 113 and the reinforcement portion are respectively connected to the second side surface 105, and the reinforcement portion is arranged around the main body 113. Since the main body 113 is connected to the second side surface 105, the reinforcement portion is circumferentially arranged at the connection between the main body 113 and the second side surface 105 through the reinforcement portion, so as to ensure the stability of the movable connection between the rotating shaft mechanism 200 and the shell 100 through the reinforcement portion and the enhanced connection strength between the connecting portion 103 and the first frame portion 101; in one embodiment, the reinforcement portion and the main body 113 are an integral structure; the reinforcement portion may have a first curved surface 114, and the first curved surface 114 is back to the main body 113, so that the first curved surface 114 is used to enhance the shear resistance performance of the main body 113. Exemplarily, the first curved surface 114 may be an arc surface.

[0130] In some embodiments, each reinforcement portion may include only the first reinforcement block, or each reinforcement portion may include only the second reinforcement block, or each reinforcement portion includes the first reinforcement block and the second reinforcement block; in a plurality of connecting portions 103, the structural form of the reinforcement portion on each connecting portion 103 may be the same, or may be different, or the structural form of the reinforcement portion on at least two connecting portions 103 may be the same. As shown in Figures 15 and 16, for example, in some connecting portions 103, the reinforcement portion of each connecting portion 103 includes a first reinforcement block 115 and a second reinforcement block 116, the main body 113 and the first reinforcement block 115 are an integral structure, the main body 113 and the second reinforcement block 116 are an integral structure, the main body 113 is provided with the first reinforcement block 115 on both sides opposite to each other in the height direction of the first frame portion 101, and the main body 113 is provided with the second reinforcement block 116 on both sides opposite to each other in the length direction of the first frame portion 101, and the main body 113, the first reinforcement block 115 and the second reinforcement block 116 are respectively provided with the second side 105 is connected; in other connecting parts 103, the reinforcement part of each connecting part 103 includes a first reinforcement block 115, the main body 113 and the first reinforcement block 115 are an integrated structure, and the main body 113 is respectively provided with the first reinforcement blocks 115 on two opposite sides in the height direction of the first frame part 101, and the main body 113 and the first reinforcement block 115 are respectively connected to the second side surface 105; in this way, the first reinforcement block 115 and / or the second reinforcement block 116 are utilized to improve the connection strength between the connecting part 103 and the first frame part 101, thereby ensuring the stability of the movable connection between the hinge mechanism 200 and the shell 100.

[0131] As shown in Figures 15 and 16, for the first reinforcement block 115 and the second reinforcement block 116, the first reinforcement block 115 is provided with a first curved surface 114, and the second reinforcement block 116 is provided with a first curved surface 114. After the reinforcement portion is provided around the main body 113, the cross-sectional area of ​​the end of the connecting portion 103 connected to the second side surface 105 is larger than the cross-sectional area of ​​the other end of the connecting portion 103, and the cross-section of the connecting portion 103 is parallel to the second side surface 105. This can better improve the connection strength at the connection between the connecting portion 103 and the second side surface 105.

[0132] It should be noted that, in some other possible embodiments, the reinforcement portion may only include the second reinforcement block 116, the main body 113 and the second reinforcement block 116 are an integral structure, and the main body 113 is respectively provided with second reinforcement blocks 116 on two opposite sides in the length direction of the first frame portion 101, the main body 113 and the second reinforcement block 116 are respectively connected to the second side surface 105, and the second reinforcement block 116 is provided with a first curved surface 114.

[0133] As shown in FIG15 , in some embodiments, the connecting portion 103 has a connection structure, which includes at least one of a hinge axis hole 117, a sliding groove 118, and a rotating arc surface 119. This allows the housing 100 to adapt to different components of the rotating shaft mechanism 200, allowing different components of the rotating shaft mechanism 200 to be movably connected to the housing 100 in corresponding manners. Each connecting portion 103 may only be provided with a hinge axis hole 117, a sliding groove 118, or a rotating arc surface 119. Exemplarily, a pin structure can be inserted into the hinge shaft hole 117 to realize the hinge connection between the corresponding components of the hinge mechanism 200 and the shell 100. Specifically, one or more swing arms in the hinge mechanism 200 can be hinged to the connecting shaft hole on the connecting part 103; and the sliding groove 118 can realize the sliding connection between the corresponding components of the hinge mechanism 200 and the shell 100. Specifically, one or more swing arms in the shaft mechanism can be slidably connected to the sliding groove 118 on the connecting part 103, so that different swing arms in the hinge mechanism 200 can be slidingly connected to the shell 100 or hinged; and the rotating arc surface 119 can realize the rotational connection between the corresponding components of the hinge mechanism 200 and the shell 100. Specifically, the door panel 202 in the hinge mechanism 200 can cooperate with the rotating arc surface 119 on the connecting part 103 to realize the rotation of the door panel 202 relative to the shell 100.

[0134] It should be noted that the connection structure is rotationally connected to the rotating shaft mechanism 200, that is, the connection structure can rotate relative to the base 201 of the rotating shaft mechanism 200. In addition, in some other possible embodiments, each connecting portion 103 can be provided with two or more of the hinge axis hole 117, the sliding groove 118, and the rotating arc surface 119.

[0135] As shown in FIG16 , in some embodiments, the rotating arc surface 119 includes a first convex arc surface 120 and a first concave arc surface 121; the connecting portion 103 includes a first sub-portion 122 and a second sub-portion 123, with the first sub-portion 122 and the second sub-portion 123 spaced apart from each other; the first sub-portion 122 defines a first groove 124, the bottom of which is provided with a first concave arc surface 121, and the second sub-portion 123 defines a first convex arc surface 120; the first concave arc surface 121 and the first convex arc surface 120 are spaced apart along the length of the first frame portion 101. Thus, the first convex arc surface 120 and the first concave arc surface 121 facilitate the rotational connection with the door panel 202 of the rotating shaft mechanism 200; and because the first convex arc surface 120 and the first concave arc surface 121 are spaced apart from each other, their coordination facilitates processing of the connecting portion 103 and ensures the stability of the overall structure of the connecting portion 103. In one embodiment, the first setting plane is perpendicular to the first convex arc surface 120, and the first setting plane is perpendicular to the first concave arc surface 121; the first convex arc surface 120 and the first concave arc surface 121 are both smooth curved surfaces, that is, there are no pits or protrusions on them; the orthographic projection of the first convex arc surface 120 in the first setting plane is a first arc, and the orthographic projection of the first concave arc surface 121 in the first setting plane is a second arc; the center of the circle corresponding to the first arc is concentrically arranged with the center of the circle corresponding to the second arc; the tangent plane at at least some points on the first convex arc surface 120 is perpendicular to the first setting plane, so that the straight line passing through the center of the circle and parallel to the X direction is the rotation axis of the door panel 202. Due to the concentric arrangement, the door panel 202 can rotate relative to the connecting portion 103 of the shell 100. The two arc-shaped side edges 125 of the first convex arc surface 120 that are opposite to each other in the longitudinal direction of the first frame portion 101 are both separated from the first concave arc surface 121 and the first sub-portion 122; the first concave arc surface 121 has two arc-shaped side edges 125 that are opposite to each other in the longitudinal direction of the first frame portion 101, and one of the arc-shaped side edges 125 of the first concave arc surface 121 is connected to the groove wall of the first groove 124, so that axial limitation of the door panel 202 can be achieved, and the other arc-shaped side edge 125 of the first concave arc surface 121 is in the form of a free edge. It should be understood that the first set plane can be any plane perpendicular to the length direction of the first frame portion 101, rather than a unique plane; and for the first convex arc surface 120 and the first concave arc surface 121, the convex arc surface and the concave arc surface are relative. For example, the two arc-shaped side edges 125 of the first convex arc surface 120 opposite to each other in the length direction of the first frame portion 101 are respectively arc lines, and the line between the two end points of the arc line passes through the solid part of the second sub-portion 123. Therefore, the arc surface is convex, that is, a convex arc surface; similarly, the two arc-shaped side edges 125 of the first concave arc surface 121 opposite to each other in the length direction of the first frame portion 101 are respectively arc lines, and the line between the two end points of the arc line is above the bottom of the groove. Therefore, the arc surface is concave, that is, a concave arc surface.It should be noted that in some other possible embodiments, some arcuate grooves or arcuate protrusions may be provided on the first convex arc surface 120 and the first concave arc surface 121, and the centers of the circles corresponding to the arcuate grooves and the arcuate protrusions are concentric with the first arc. Although the arcuate grooves or arcuate protrusions are provided, they only serve to axially limit the door panel 202 when the door panel 202 rotates relative to the housing 100, so that the door panel 202 does not wobble along the axial direction of the rotating shaft mechanism 200. Correspondingly, the door panel 202 is provided with an arcuate protrusion that cooperates with the arcuate groove on the rotating arc surface 119, or the door panel 202 is provided with an arcuate groove that cooperates with the arcuate protrusion on the rotating arc surface 119. Of course, in some other possible embodiments, pits may be allowed on the first convex arc surface 120 and the first concave arc surface 121, which does not affect the rotation.

[0136] With reference to Figures 17 to 19 , Figure 17 is a schematic structural diagram of a door panel 202 according to an embodiment of the present application, Figure 18 is a schematic partial structural diagram of the door panel 202 shown in Figure 17 , and Figure 19 is a schematic partial structural diagram of the door panel 202 shown in Figure 17 from another perspective. Figures 17 to 19 illustrate, from different angles, a curved surface structure 207 corresponding to the rotating arc surface 119 provided on the door panel 202. The curved surface structure 207 includes a second convex arc surface 204 and a second concave arc surface 205; the second convex arc surface 204 and the second concave arc surface 205 are spaced apart in the length direction of the door panel 202. In conjunction with Figures 20 and 21, Figure 20 is a structural schematic diagram (cross-section) of the door panel and the shell being rotatably connected in the embodiment of the present application, and Figure 21 is another structural schematic diagram (cross-section) of the door panel 202 and the shell 100 being rotatably connected in the embodiment of the present application. The door panel 202 of the rotating shaft mechanism 200 is rotatably connected to the connecting portion 103. Since the second convex arc surface 204 and the second concave arc surface 205 are spaced apart in the length direction of the door panel 202, and the first concave arc surface 121 and the first convex arc surface 120 are spaced apart in the length direction of the first frame portion 101, the door panel 20 2 and the connecting portion 103 are matched with the rotating arc surface 119 through the above-mentioned curved surface structure 207, the second convex arc surface 204 on the door panel 202 is matched with the first concave arc surface 121 on the connecting portion 103, and the second concave arc surface 205 is matched with the first convex arc surface 120 on the connecting portion 103, thereby realizing the rotational connection between the shell 100 and the door panel 202; in addition, since the second convex arc surface 204 and the second concave arc surface 205 are arranged at intervals, after the two are matched, it is beneficial to process the door panel 202 and ensure the stability of the overall structure of the door panel 202. In one embodiment, the orthographic projection of the second convex surface 204 within the third set plane is a third circular arc, and the orthographic projection of the second concave surface 205 within the third set plane is a fourth circular arc. The center of the third circular arc is concentric with the center of the fourth circular arc. The tangent plane at at least some points on the second convex surface 204 is perpendicular to the third set plane. The second convex surface 204 and the second concave surface 205 are both smooth curved surfaces, i.e., without pits or protrusions. The concentric arrangement ensures that the door panel 202 can rotate relative to the connecting portion 103 of the housing 100. It should be understood that the third set plane can be any plane perpendicular to the length of the door panel 202, rather than a single plane. It should be noted that, for the second convex arc surface 204 and the second concave arc surface 205, the convex arc surface and the concave arc surface are relative and can be defined with reference to the description of the first convex arc surface 120 and the first concave arc surface 121; in addition, in some other possible implementations, pits may be allowed on the second convex arc surface 204 and the second concave arc surface 205, which does not affect the rotation.

[0137] Referring to FIG. 22 , FIG. 22 is another structural schematic diagram of the connecting portion 103 on the shell 100 in an embodiment of the present application having a rotating arc surface. In other embodiments, the rotating arc surface 119 includes a first convex arc surface 120 and a first concave arc surface 121, and the connecting portion 103 has a second groove 128. The second groove 128 is mainly surrounded by the first convex arc surface 120 and the first concave arc surface 121. In this way, the direction of the second groove 128 is arc-shaped, so that the door panel 202 can rotate relative to the connecting portion 103. The first convex arc surface 120 and the first concave arc surface 121 are at the length of the first frame portion 101. The first convex arc surface 120 and the first concave arc surface 121 are arranged without intervals in the direction, that is, at least partially overlap in the longitudinal direction of the first frame portion 101; the first convex arc surface 120 and the first concave arc surface 121 respectively intersect with the second set plane; the intersection line of the first convex arc surface 120 and the second set plane is a first arc, and the intersection line of the first concave arc surface 121 and the second set plane is a second arc; the center of the circle corresponding to the first arc is concentric with the center of the circle corresponding to the second arc; the tangent plane at at least some points on the first convex arc surface 120 is perpendicular to the second set plane, which facilitates the rotatable connection between the door panel 202 and the connecting portion 103 of the rotating shaft mechanism 200. It should be understood that the second set plane can be any plane perpendicular to the longitudinal direction of the first frame portion 101, and this plane is not the only plane.

[0138] 23 to 25 , FIG23 is another structural schematic diagram of the door panel 202 in an embodiment of the present application, FIG24 is another structural schematic diagram of the door panel 202 rotatably connected to the shell 100 in an embodiment of the present application, and FIG25 is a cross-sectional view of the door panel 202 rotatably connected to the shell 100 shown in FIG24 . In some embodiments, the door panel 202 of the hinge mechanism 200 is rotatably connected to the connecting portion 103, and the door panel 202 is provided with a curved surface structure 207 corresponding to the rotating arc surface 119. The curved surface structure 207 includes a second convex curved surface 204 and a second concave curved surface 205; the door panel 202 has an arc structure, and the arc structure has a second convex curved surface 204 and a second concave curved surface 205; the second convex curved surface 204 and the second concave curved surface 205 are not spaced apart in the length direction of the door panel 202, that is, the two are at least partially overlapped in the length direction of the door panel 202; since the second convex curved surface 204 and the second concave curved surface 205 are at least partially overlapped in the length direction of the door panel 202, the first concave curved surface 121 and the first convex curved surface 120 are at least partially overlapped in the length direction of the first frame portion 101. The two connecting parts 103 are arranged in an overlapping manner, so after the door panel 202 and the connecting part 103 are matched with the rotating arc surface 119 through the above-mentioned curved surface structure 207, the second convex arc surface 204 on the door panel 202 is matched with the first concave arc surface 121 on the connecting part 103, and the second concave arc surface 205 is matched with the first convex arc surface 120 on the connecting part 103, thereby realizing the rotational connection between the shell 100 and the door panel 202; in addition, since the second convex arc surface 204 and the second concave arc surface 205 are arranged at intervals, after the two are matched, it is beneficial to process the door panel 202 and ensure the stability of the overall structure of the door panel 202. In one embodiment, the second convex surface 204 and the second concave surface 205 each intersect with a third set plane; the intersection of the second convex surface 204 and the third set plane forms a third arc, and the intersection of the second concave surface 205 and the third set plane forms a fourth arc; the center of the third arc is concentric with the center of the fourth arc; the tangent plane at at least some points on the second convex surface 204 is perpendicular to the second set plane; the second convex surface 204 and the second concave surface 205 are both smooth curved surfaces, i.e., without pits or protrusions; the concentric arrangement ensures that the door panel 202 can rotate relative to the connecting portion 103 of the housing 100. It should be understood that the third set plane can be a plane perpendicular to the length of the door panel 202, and this plane is not the only plane. It should be noted that in some other possible embodiments, pits can be allowed on the second convex surface 204 and the second concave surface 205, and this does not affect rotation.

[0139] In combination with Figures 26 and 27, Figure 26 is a schematic diagram of the local structure of the shell 100 in an embodiment of the present application, in which different connecting parts 103 are respectively provided with sliding grooves 118 and hinge shaft holes 117, and Figure 27 is a schematic diagram of the local structure of the shell 100 from another perspective shown in Figure 26; in some embodiments, a sliding groove 118 is provided on the connecting part 103, and the sliding groove 118 is mainly a cavity surrounded by multiple first planes 129, which is conducive to achieving the stability of the sliding connection between the first swing arm 203 of the rotating shaft mechanism 200 and the connecting part 103, and the sliding path is a straight line.

[0140] In combination with Figures 28 and 29, Figure 28 is a schematic diagram of the local structure in which a first swing arm 203 is slidably connected to the shell 100 in an embodiment of the present application, and Figure 29 is a schematic diagram of the local structure in which another first swing arm 203 is hinged to the shell 100 in an embodiment of the present application. In some embodiments, the number of first swing arms 203 in the rotating shaft mechanism 200 can be multiple, and the connection methods between different first swing arms 203 and the shell 100 can be the same or different, that is, the method of active connection between some first swing arms 203 and the shell 100 is a sliding connection (see Figure 28), and the method of active connection between other first swing arms 203 and the shell 100 is a hinged connection through a pin structure (see Figure 29).

[0141] As shown in Figure 28, illustratively, one or more first swing arms 203 in the rotating shaft mechanism 200 are slidingly connected to the shell 100, one end of the first swing arm 203 of the rotating shaft mechanism 200 is slidingly connected to the connecting portion 103 through a sliding groove 118, and the opposite end of the first swing arm 203 is rotationally connected to the base 201. The rotational connection can be achieved by a pin hinge or a virtual axis rotational connection achieved by an arc surface structure.

[0142] Please refer to Figures 26 and 27. In some embodiments, the connecting portion 103 includes a plurality of first sub-segments 130 arranged at intervals, and a hinge axis hole 117 is opened on the first sub-segment 130. The hinge axis holes 117 on the plurality of first sub-segments 130 are coaxially arranged; the axis of the hinge axis hole 117 is parallel to the length direction of the first frame portion 101. In this way, the plurality of first sub-segments 130 arranged at intervals can improve the structural stability of the hinge between the swing arm of the rotating shaft mechanism 200 and the shell 100, and can also help reduce the width of the swing arm in the rotation axis direction. As shown in Figure 29, one end of one or more first swing arms 203 in the corresponding rotating shaft mechanism 200 has a plurality of second sub-segments 206 arranged at intervals, and a hinge shaft hole 117 is opened on the second sub-segment 206. The hinge shaft holes 117 on the plurality of second sub-segments 206 are coaxially arranged. In this way, the first sub-segments 130 and the second sub-segments 206 are alternately arranged in the axial direction of the rotating shaft mechanism 200, and then the pin structure is passed through the hinge shaft hole 117 on the first sub-segment 130 and the hinge shaft hole 117 on the second sub-segment 206, so that one end of the first swing arm 203 is hinged to the shell 100, and the other end of the first swing arm 203 is rotatably connected to the base 201.

[0143] It should be noted that the first swing arm 203 can be used as a swing arm for the synchronization function of the rotating shaft mechanism 200 , and can also be used as a swing arm for the damping function in the rotating shaft mechanism 200 .
