Description

Technical Field

[0001] The present application relates to the technical field of electronic equipment, and in particular to a supporting assembly, a protective shell and an electronic device. Background Art

[0002] With the widespread popularity of electronic devices in modern life, people often need to equip themselves with supporting devices to help them adjust to a suitable viewing angle in order to obtain a more comfortable and convenient viewing experience when using electronic devices. In the field of smartphones, their technology and form continue to evolve, and some of them have evolved from traditional candy-bar phones to innovative folding phones.

[0003] Due to its unique foldable design, folding machines have a variety of different usage forms, and accordingly also have a variety of support form requirements such as vertical support in folded state, lateral support in folded state, vertical support in unfolded state, and lateral support in unfolded state. However, the existing bracket forms have serious limitations. Most of them can only provide support for a certain specific form and cannot fully meet the diverse support requirements of folding machines. This greatly limits the effective use of folding machines in different scenarios. In addition, another significant problem with existing brackets is that their hinges are usually exposed. The exposed hinge of the bracket not only destroys the simple and smooth appearance lines of the folding machine itself, but also greatly affects the user experience of the folding machine. Summary of the invention

[0004] The present application provides a support component, a protective shell and an electronic device. The support component can adjust the bracket according to different support requirements to adapt to different forms of the electronic device.

[0005] The technical solution is as follows: A first aspect of the present application provides a support assembly, which is arranged on an electronic device or a protective shell, and the support assembly includes: a base, which is installed on the electronic device or the protective shell; a rotating part, which is rotatably installed on the base; a supporting part, which is flipably installed on the rotating part, and a limiting part is arranged between the supporting part and the rotating part bracket, and the limiting part includes a plurality of first limiting structures arranged at intervals along the flipping direction of the supporting part, each of the first limiting structures corresponds to a different flipping angle of the supporting part, and the supporting part cooperates with different first limiting structures to limit the supporting part to different flipping angles.

[0006] Through the above technical scheme, the support part cooperates with different first limiting structures to limit the support part to different flipping angles. The flipping of the support part combined with the rotation of the rotating part can match the various form requirements of the folded state vertical support, folded state lateral support, unfolded state vertical support and unfolded state lateral support of the folding machine, overcomes the defect that the existing bracket can only meet the support of a single form, greatly broadens the applicability of the support component in different usage scenarios, and allows users to easily adjust the support part to the ideal angle when operating the folding machine for various activities such as watching videos, video calls or text editing, to ensure the stable placement of the equipment.

[0007] In a possible design, the limiting part further includes a second limiting structure, one of the first limiting structure and the second limiting structure is arranged on the supporting part, and the other is arranged on the rotating part, there are multiple first limiting structures, and the first limiting structure and the second limiting structure cooperate to limit the flipping of the supporting part. The double limiting structure helps to improve the durability of the supporting assembly. In the process of frequently flipping the supporting part to adapt to different usage scenarios, compared with a single limiting structure, it can reduce the wear, deformation or damage of the supporting part itself caused by long-term concentrated force, thereby extending the service life of the supporting assembly. In a possible design, the first limiting structure includes a limiting convex portion, and the second limiting structure includes a limiting concave portion, and both the limiting concave portion and the limiting convex portion are smoothly arranged. When the user adjusts the support angle, there is no need to apply excessive external force to overcome resistance. Switching from one support angle to another angle makes the operation feel smoother.

[0008] In one possible design, the support portion is hinged to the rotating portion, one of the rotating portion and the support portion is provided with a groove, and the other is provided with a boss, the boss can be flipped and arranged in the groove, and the limiting portion is arranged between the groove and the boss. The groove and the boss utilize the space between the rotating portion and the support portion, making the structure of the entire support assembly more compact. Compared with some support assemblies that use external complex connections or guide structures, the embedded grooves and bosses reduce the additional space occupation, so that when the support assembly is installed on an electronic device or a protective case, it will not significantly increase the overall volume of the device or change the coordination of its appearance contour, reducing the risk of component damage or support failure due to loose structure.

[0009] In a possible design, the support assembly further includes a graduation part, which is arranged on the base and located between the base and the rotating part, one of the rotating part and the graduation part is provided with a plurality of first graduation limit structures arranged at intervals along a circular path, and the other is provided with a second graduation limit structure, and the second graduation limit structure cooperates with at least one first graduation limit structure. The plurality of first graduation limit structures arranged at intervals along the circular path cooperate with the second graduation limit structure, and when the rotating part rotates relative to the base, the rotation angle can be accurately limited to a specific graduation value.

[0010] In a possible design, one of the first indexing limit structure and the second indexing limit structure is an indexing groove, and the other is an elastic buckle. Since the indexing grooves are multiple fixed positions arranged at intervals along a circular path, the rotation angle of the rotating part can be accurately limited to the angle corresponding to each groove, avoiding the arbitrariness and uncertainty of the rotation angle. The mechanically simulated click sound can bring a sense of control, similar to the sound made when a mechanical switch or precision instrument is operated, which will make the user subconsciously feel the high quality and precision of the product.

[0011] In a possible design, a mounting boss is provided on the base, the indexing portion includes a indexing ring, the indexing ring is fixedly sleeved on the mounting boss, and the inner wall of the indexing ring is matched with the outer wall of the mounting boss. The tight fit between the mounting boss and the inner wall of the indexing ring can effectively prevent the indexing ring from shaking, shifting or falling off when subjected to external force. In a possible design, the rotating part includes a first rotating ring and a second rotating ring, the supporting part is hinged on the first rotating ring, the boss is arranged on the supporting part, the groove is arranged on the second rotating ring, and the boss is matched with the inner side of the groove. The groove on the second rotating ring can be used to hide the hinge axis of the supporting part, and hiding the hinge axis can improve the overall aesthetics of the supporting assembly and the entire electronic device or protective shell. In a possible design, the support assembly includes a hinge assembly, the hinge assembly includes a first hinge piece and a second hinge piece that are hinged to each other, the first hinge piece is connected to the support portion, the second hinge piece is connected to the first swivel, the first limiting structure is arranged on the inner side wall of the groove, and the second limiting structure is arranged on the side wall of the boss. When the support portion is in a storage position that is not turned over for use, since the hinge shaft is located between the first swivel and the second swivel, the support portion can be flat against the first swivel, thereby reducing the space occupied by the support assembly in a non-working state. In a possible design, a mounting boss is provided on the base, the support assembly includes a top cover, the top cover is provided on the mounting boss, the top cover includes a first limiting flange, and the first limiting flange is provided on the inner side of the first rotating ring, so as to limit the axial movement of the first rotating ring and prevent the first rotating ring from falling off. In a possible design, an outer flange is provided on the side wall of the second swivel, a first support flange and a second support flange are provided at intervals along the depth direction on the inner side wall of the base, and the support assembly further includes an anti-slip portion, which is mounted on the second support flange and forms a rotation groove with the first support flange, and the outer flange is rotatably mounted in the rotation groove. The first support flange and the anti-slip portion limit the outer flange of the second swivel from above and below to prevent the outer flange from falling out of the rotation groove, thereby ensuring that the second swivel can stably rotate relative to the base without displacement or separation.

[0012] In a possible design, the support portion is a support ring. When it is necessary to move, adjust or take the electronic device installed with the support assembly, the user can easily pass his fingers through the support ring. A second aspect of the present application provides a protective shell, which includes a shell body, on which a support assembly is arranged, and the support assembly is the above-mentioned support assembly.

[0013] Through the above technical solution, since the protective shell includes the above supporting assembly, it at least has all the beneficial effects of the supporting assembly, which will not be repeated here.

[0014] A third aspect of the present application provides an electronic device, characterized in that the electronic device includes a support assembly, and the support assembly is the above-mentioned support assembly.

[0015] Through the above technical solution, since the electronic device includes the above supporting assembly, it at least has all the beneficial effects of the supporting assembly, which will not be described in detail here. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] It should be understood that the "multiple" mentioned in this application refers to two or more. In the description of this application, unless otherwise specified, " / " means or, for example, A / B can mean A or B; "and / or" in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, in order to facilitate the clear description of the technical solution of this application, the words "first" and "second" are used to distinguish between the same items or similar items with basically the same functions and effects. Those skilled in the art can understand that the words "first" and "second" do not limit the quantity and execution order, and the words "first" and "second" do not limit them to be different.

[0018] In the related art, with the widespread popularity of electronic devices in modern life, when people use electronic devices, in order to obtain a more comfortable and convenient viewing experience, they often need to equip supporting devices to assist in supporting the electronic devices and adjust them to a suitable viewing angle. In the field of smart phones, their technology and forms are constantly evolving, and some of them have developed from traditional straight-panel phones to innovative folding phones. Due to their unique foldable design, folding phones have a variety of different usage forms, and accordingly also have a variety of support form requirements such as folded vertical support, folded lateral support, unfolded vertical support, and unfolded lateral support. However, the existing bracket forms have serious limitations. Most of them can only provide support for a certain specific form and cannot fully meet the diverse support requirements of folding machines, which greatly limits the effective use of folding machines in different scenarios. In addition, another significant problem with existing brackets is that their shafts are usually exposed. The exposed shaft of the bracket not only destroys the simple and smooth appearance lines of the folding machine itself, but also greatly affects the user experience of the folding machine. In order to solve the technical problem that the supporting component existing in the above-mentioned related technology cannot meet the supporting requirements of different forms of electronic devices, this embodiment provides a supporting component, and the supporting component is arranged on the electronic device or the protective shell. The embodiment of the present application also provides an electronic device using the above-mentioned supporting component. The supporting component and the electronic device provided in the embodiment of the present application are explained in detail below.

[0019] The electronic device particularly refers to a foldable electronic device, and the protective case particularly refers to a protective case mounted on the foldable electronic device. Figure 1A foldable electronic device 1 is provided in an embodiment of the present application. The foldable electronic device 1 includes but is not limited to a cell phone, a notebook computer, a tablet personal computer, a laptop computer, etc. In the embodiment of the present application, the foldable electronic device 1 is described as a cell phone.

[0020] Figure 1 The foldable electronic device 1 is in a folded state. Figure 2 The foldable electronic device 1 is shown in a semi-expanded state. Figure 3 The foldable electronic device 1 is shown in an unfolded state. Figure 2 The unfolding angle α of the foldable electronic device 1 is 90 degrees. Figure 3 The unfolding angle β of the foldable electronic device 1 is 180 degrees.

[0021] 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 1 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 1 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. The angles described below can be understood in the same way.

[0022] The foldable electronic device 1 shown in the embodiment of the present application is an electronic device that can be folded once. In some other embodiments, the foldable electronic device 1 can also be an electronic device that can be folded multiple times (more than twice). In this case, the foldable electronic device 1 can include multiple parts, two adjacent parts can be folded relatively close to each other until the foldable electronic device 1 is in a folded state, and two adjacent parts can be unfolded relatively far away from each other until the foldable electronic device 1 is in an unfolded state.

[0023] For the convenience of description, in this embodiment, the width direction of the foldable electronic device 1 is defined as the X-axis direction, the length direction of the foldable electronic device 1 is defined as the Y-axis direction, and the thickness direction of the foldable electronic device 1 is defined as the Z-axis direction. The X-axis direction, the Y-axis direction and the Z-axis direction are mutually perpendicular. It should be noted that the dimension in the width direction is not necessarily larger than the dimension in the length direction. It is worth noting that the qualifiers of the relevant positional relationships such as parallel and perpendicular mentioned in this embodiment are all for the current technological level, rather than an absolute and strict definition in the mathematical sense. A small amount of deviation is allowed, and both approximately parallel and approximately perpendicular are acceptable. For example, A and B are parallel, which means that A and B are parallel or approximately parallel, and the angle between A and B can be between 0 degrees and 10 degrees. For example, A and B are perpendicular, which means that A and B are perpendicular or approximately perpendicular, and the angle between A and B can be between 80 degrees and 100 degrees. This embodiment uses directional terms such as "top", "bottom", "left", "right", "front" and "back" to describe the foldable electronic device 1. The orientation is mainly based on the position of the foldable terminal in the attached Figure 3 The display directions are explained in the figure, with the positive direction of the Y axis being the "top", the negative direction of the Y axis being the "bottom", the positive direction of the X axis being the "left", the negative direction of the X axis being the "right", the positive direction of the Z axis being the "front", and the negative direction of the Z axis being the "back".

[0024] See also Figure 4 , Figure 4 yes Figure 3Schematic diagram of the exploded structure. The foldable electronic device 1 includes a first housing 20, a second housing 30, a folding hinge mechanism 10 and a display screen 40, and the folding hinge mechanism 10 is connected between the first housing 20 and the second housing 30. Specifically, the first housing 20 and the second housing 30 are respectively installed on both sides of the folding hinge mechanism 10 in the width direction, that is, the first housing 20 and the second housing 30 are respectively installed on the left and right sides of the folding hinge mechanism 10. The first housing 20 and the second housing 30 rotate relative to each other through the folding hinge mechanism 10. The rotation directions of the first housing 20 and the second housing 30 are opposite. The display screen 40 is laid on one side of the first housing 20, the second housing 30 and the folding hinge mechanism 10, specifically, the display screen 40 is laid on the front side of the first housing 20, the second housing 30 and the folding hinge mechanism 10. The display screen 40 includes a first part 41, a second part 42 and a foldable part 43. The foldable part 43 is located between the first part 41 and the second part 42, and the foldable part 43 can be bent along the Y-axis direction. The first part 41, the second part 42 and the foldable part 43 together constitute a display screen 40. In this embodiment, the display screen 40 adopts a flexible display screen, for example, 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 (MIL-LED) display screen, a micro organic light-emitting diode (MIL-LED) display screen, a micro organic light-emitting diode (MIL-LED) display screen, or a quantum dot light emitting diode (QLED) display screen.

[0025] The first housing 20 and the second housing 30 are relatively close to each other to drive the display screen 40 to fold, so that the foldable electronic device 1 is folded. When the foldable electronic device 1 is in the folded state, the foldable portion 43 of the display screen 40 is bent, and the first portion 41 and the second portion 42 are arranged opposite to each other. At this time, the display screen 40 is between the first housing 20 and the second housing 30, which can greatly reduce the probability of the display screen 40 being damaged, and effectively protect the display screen 40.

[0026] Please also read Figure 2 and Figure 4, the first housing 20 and the second housing 30 rotate relative to each other through the folding hinge mechanism 10, and the first housing 20 and the second housing 30 move away from each other to drive the display screen 40 to unfold, so that the foldable electronic device 1 is unfolded to a semi-expanded state. When the foldable electronic device 1 is in the semi-expanded state, the first housing 20 and the second housing 30 unfold to an angle of α, the first part 41 and the second part 42 unfold relative to each other, and drive the foldable part 43 to unfold. At this time, the angle between the first part 41 and the second part 42 is α.

[0027] Please also read Figure 3 and Figure 4 , the first shell 20 and the second shell 30 rotate relative to each other through the folding hinge mechanism 10, the first shell 20 and the second shell 30 can adopt the same structure, and the first shell 20 and the second shell 30 can be arranged in mirror symmetry with respect to the folding hinge mechanism 10. The first shell 20 and the second shell 30 are relatively far away from each other, so that the display screen 40 is further unfolded until the foldable electronic device 1 is flattened. When the foldable electronic device 1 is in the unfolded state, the angle between the first shell 20 and the second shell 30 is β. The foldable part 43 is unfolded, and the first part 41 and the second part 42 are relatively unfolded. At this time, the angles between the first part 41, the second part 42 and the foldable part 43 are all β, and the display screen 40 has a large display area, realizing a large screen display of the foldable electronic device 1, and improving the user experience. It should be noted that the angle α and the angle β are both the angles between the first shell 20 and the second shell 30, which are only used to distinguish the different angles between the first shell 20 and the second shell 30 of the foldable electronic device 1 in different states. The angle α refers to the angle between the first shell 20 and the second shell 30 when the foldable electronic device 1 is in a semi-expanded state; the angle β refers to the angle between the first shell 20 and the second shell 30 when the foldable electronic device 1 is in an expanded state.

[0028] It should be understood that the foldable electronic device 1 shown in the embodiment of the present application is folded inwardly, and the display screen 40 of the foldable electronic device 1 in the folded state is located on the inner side of the folding hinge mechanism 10. In some other embodiments, the foldable electronic device 1 can also be folded in outwardly, and in this case, the display screen 40 of the foldable electronic device 1 in the folded state is located on the outer side of the folding hinge mechanism 10. The main function of the support component is to be installed on the base component to play a supporting role, such as supporting the display screen, enhancing the stability of the folding hinge mechanism, etc., and is an important component to ensure the normal operation of the foldable electronic device. The folding hinge mechanism mainly includes a base component and a swing arm component. The swing arm component is rotatably installed on the base component, and the two are installed in conjunction with an axis structure. The swing arm can rotate and slide relative to the base, so that the device can achieve the functions of folding and unfolding. The swing arm component cooperates with the first shell and the second shell respectively.

[0029] See also Figures 5 to 10 , the support assembly provided in the embodiment of the present application is arranged on the electronic device or the protective shell 2, and the support assembly includes a base 50, a rotating part 60, and a supporting part 70. The base 50 is installed on the electronic device or the protective shell 2; the rotating part 60 is rotatably installed on the base 50; the supporting part 70 is flippably installed on the rotating part 60, and a limiting part 80 is arranged between the supporting part 70 and the bracket of the rotating part 60. The limiting part 80 includes a plurality of first limiting structures 81 arranged at intervals along the flipping direction of the supporting part 70, and each first limiting structure 81 corresponds to a different flipping angle of the supporting part 70, and the supporting part 70 cooperates with different first limiting structures 81 to limit the supporting part 70 to different flipping angles. It should be noted that the protective shell 2 is a shell-like accessory for wrapping electronic devices, and its main function is to protect the electronic devices from external physical damage, such as collision, scratching, etc. In the embodiment of the present application, the support assembly can also be installed on the protective shell 2, so that the protective shell 2 has the function of supporting the electronic device in addition to the protection function, thereby increasing the practicality of the protective shell 2.

[0030] in, Figure 5 The support assembly is in the storage position. Figure 6 The supporting component state in the embodiment can be used for vertical support of the foldable electronic device when it is in the folded state. Figure 7 and Figure 8 The supporting component state in the embodiment can be used for vertical support of the foldable electronic device when it is in the unfolded state. Fig. 9 and Fig.10 The supporting component state can be used for lateral support of the foldable electronic device when it is in a folded state and an unfolded state.

[0031] See also Fig.11 , Fig.12 , Fig.14It should be noted that the base 50 in the embodiment of the present application plays the role of installing the entire support assembly on the electronic device or the protective shell 2. For example, it can be fixed to the electronic device or the protective shell 2 by means of pasting, snapping or screws, etc., to provide a stable support foundation for the subsequent movement of the rotating part 60 and the supporting part 70. The rotating part 60 is a component that can rotate relative to the base 50. It is rotatably mounted on the base 50, so that the support assembly has the ability to adjust the angle.

[0032] See also Fig.11 , Fig.12 and Fig.15 It should be noted that the support portion 70 in the embodiment of the present application is a component that contacts the outside and plays an actual supporting role. It can be flipped on the rotating portion 60, and fixed support at different angles can be achieved through the limit portion 80 between the rotating portion 60. The support portion 70 can be flipped on the rotating portion 60 according to the needs of the user, and can achieve the function of stably supporting the electronic device at a specific flip angle through cooperation with the limit portion 80, so as to meet the support requirements of the electronic device in different usage forms (such as vertical and horizontal support in a folded or unfolded state, etc.).

[0033] Please note that Fig.11 , Fig.12 , Fig.15 , Fig.16 , Fig.17 The limiting part 80 in the embodiment of the present application is a structural part arranged between the support part 70 and the rotating part 60, and includes a plurality of first limiting structures 81 arranged at intervals along the flipping direction of the support part 70. Through the cooperation of these first limiting structures 81 and the support part 70, the support part 70 can accurately stay at different flipping angles during the flipping process, thereby achieving stable support for the electronic device at a variety of specific angles, ensuring the accuracy and stability of the support. Each first limiting structure 81 corresponds to a different flipping angle of the support part 70. When the support part 70 interacts and cooperates with a certain first limiting structure 81 during the flipping process, the support part 70 can be limited to the specific corresponding angle, thereby achieving stable support for the electronic device at the specific angle.

[0034] In some examples, the support portion 70 is a metal sheet or plastic sheet with a certain thickness and elasticity, one end of which is connected to the rotating portion 60 by a hinge to achieve a flip function. The first limiting structure 81 is a plurality of semicircular grooves 63 arranged on the bracket of the rotating portion 60, and these grooves 63 are evenly spaced along the flipping path of the support portion 70, and the radius of each groove 63 is adapted to the thickness of the support portion 70.

[0035] When the support portion 70 is in the initial position, it is basically in the same plane as the rotating portion 60 or slightly inclined. When the user needs to adjust the support angle, for example, to adjust the electronic device to the horizontal support state in the unfolded state, the user manually flips the support portion 70 upward. During the flipping process, the edge of the support portion 70 gradually approaches the semicircular groove 63. When the support portion 70 flips to a specific angle, its edge just fits into the corresponding semicircular groove 63. Due to the shape and size restrictions of the groove 63, the support portion 70 cannot continue to flip freely, and is thus stably restricted to this angle, thereby achieving horizontal support in the unfolded state.

[0036] For another example, when switching to the folded vertical support, the user flips the support part 70, and the support part 70 will come out of the current groove 63, and continue to flip until it reaches the position of the semicircular groove 63 corresponding to the folded vertical support, and then snaps into it again to complete the angle adjustment, thereby providing the folding machine with stable folded vertical support.

[0037] The support assembly of the embodiment of the present application achieves close cooperation between the support part 70 and the rotating part 60 through the limiting part 80. The multiple first limiting structures 81 correspond to different flipping angles, which can match the various form requirements of the folded state vertical support, folded state lateral support, unfolded state vertical support and unfolded state lateral support of the folding machine, etc., overcomes the defect that the existing bracket can only meet the support of a single form, greatly broadens the applicability of the support assembly in different usage scenarios, and allows users to easily adjust the support part 70 to an ideal angle when operating the folding machine for various activities such as watching videos, video calls or text editing, to ensure the stable placement of the device.

[0038] Whether it is folded vertical support for handheld reading or one-handed operation, or folded horizontal support for watching widescreen videos, or unfolded vertical and horizontal support to meet different office and entertainment application scenarios, they can all be accurately matched, effectively overcoming the limitation of traditional brackets that can only meet the support of a single form, and greatly improving the adaptability of the support components to the diverse usage scenarios of folding machines.

[0039] See also Fig.11 , Fig.12 , Fig.15 , Fig.16 , Fig.17The limiting part 80 of the embodiment of the present application also includes a second limiting structure 82. One of the first limiting structure 81 and the second limiting structure 82 is arranged on the support part 70, and the other is arranged on the rotating part 60. There are multiple first limiting structures 81, and the first limiting structure 81 and the second limiting structure 82 cooperate to limit the flipping of the support part 70. Compared with relying on a single limiting structure, the double limiting structure can more accurately control the position of the support part 70 at different flipping angles, effectively reduce the possibility of the support part 70 shaking, offsetting or even deviating from the preset angle due to external interference or accidental collision, and provide an extremely stable support foundation for the electronic device. For example, in the scenario where the user operates the folding machine for video viewing or text editing, which requires long-term stable support, even if there is slight vibration in the surrounding environment or the user accidentally touches the device, the support part 70 can still rely on the synergistic effect of the first limiting structure 81 and the second limiting structure 82 to maintain the set angle, ensuring that the device will not shake or tip over, greatly improving the safety and reliability of the device during use.

[0040] The double limit structure helps to improve the durability of the support assembly. When the support portion 70 is frequently flipped to adapt to different usage scenarios, compared with a single limit structure, it can reduce the wear, deformation or damage of the support portion 70 itself caused by long-term concentrated force, thereby extending the service life of the support assembly.

[0041] See also Fig.15 , Fig.16 , Fig.17, the first limiting structure 81 of the embodiment of the present application includes a limiting convex part, and the second limiting structure 82 includes a limiting concave part. The limiting concave part and the limiting convex part are both smoothly arranged, which reduces the friction coefficient between the limiting convex part and the limiting concave part during the matching process. Compared with the structure with angular or rough surface, the wear degree of the support part 70 is significantly reduced in the process of frequent flipping to adapt to different usage scenarios. The possibility of support failure or angle deviation caused by wear of the limiting structure is reduced, and the maintenance and replacement costs are reduced. The smooth limiting convex part and the limiting concave part make the flipping and switching process of the support part 70 smoother. When the user adjusts the support angle, there is no need to apply excessive external force to overcome the resistance. Switching from one support angle to another angle, the operation feels smoother. By using the cooperation of the limiting concave part and the limiting convex part, when the user adjusts the angle, it can be judged by touch whether the flip is in place, thereby realizing the foolproof limit. When the user adjusts the angle of the support part 70, as the support part 70 flips, the limiting convex part moves along a predetermined trajectory. During normal angle adjustment, the user can feel the relative sliding of the limiting protrusion and the surrounding structure at different positions. When the support portion 70 is flipped to a specific preset angle, the limiting protrusion will accurately slide into the corresponding limiting recess. At this time, the user's fingers can clearly perceive a change that is completely different from the previous sliding touch. The method of judging whether the flip is in place by touch has a significant anti-fool effect. For users who use the support assembly for the first time, there is no need for complicated instructions or precise visual judgment. Only by relying on the difference in touch felt by the fingers during natural operation, they can easily know whether the support portion 70 has been adjusted to the correct angle position.

[0042] For some examples, see Fig.17 Three limiting recesses are arranged on the rotating part 60, which correspond to the closed state of the supporting part 70 from top to bottom, the vertical supporting opening and closing angle, and the horizontal supporting opening and closing angle.

[0043] In some examples, the first limiting structure 81 is a magnetic protrusion, and the second limiting structure 82 is a magnetic concave block. The magnetic protrusion can be a plurality of small permanent magnets embedded on the surface of one side of the support portion 70, and these permanent magnets are distributed at certain angles. The magnetic concave block is a pit with opposite magnetic poles arranged at a position corresponding to the magnetic protrusion on the rotating portion 60. When the support portion 70 is flipped to a suitable angle, the magnetic protrusion and the magnetic concave block attract each other and fit tightly. For example, when the folder is vertically supported in the unfolded state for document reading, the adsorption effect of the magnetic protrusion and the magnetic concave block can firmly fix the support portion 70 at this angle, providing stable reading support for the user.

[0044] In some examples, the first limiting structure 81 is a card slot, and the second limiting structure 82 is an elastic card buckle 931. The elastic card buckle 931 is an elastic plastic or metal card buckle arranged on the edge of the support portion 70. The head of the card buckle is hook-shaped and can be elastically deformed to a certain extent. The card buckle is regularly arranged along the flipping direction of the support portion 70. The card slot is a corresponding opening structure on the rotating portion 60. When the support portion 70 flips, the elastic card buckle 931 will be stuck in the card slot due to its own elastic deformation when passing through the card slot. For example, when the folding machine is in a folded state and supported horizontally for watching videos, the elastic card buckle 931 is stuck in the card slot, so that the support portion 70 is stabilized at this angle, providing stable support for video viewing, and when the angle needs to be adjusted, this structure can continue to flip the support portion 70 by applying appropriate external force to disengage the elastic card buckle 931 from the card slot.

[0045] See also Fig.15 , Fig.16 , Fig.17 The support portion 70 of the embodiment of the present application is hinged to the rotating portion 60. One of the rotating portion 60 and the support portion 70 is provided with a groove 63, and the other is provided with a boss 71. The boss 71 is flippably arranged in the groove 63, and the limiting portion 80 is arranged between the groove 63 and the boss 71. The cooperation between the groove 63 and the boss 71 provides guidance and constraint for the flipping of the support portion 70. When the support portion 70 is flipped relative to the rotating portion 60, the boss 71 moves along a specific trajectory in the groove 63, so that the flipping path of the support portion 70 is more stable. The limiting portion 80 is arranged between the groove 63 and the boss 71, so as to realize the precise control of the flipping angle of the support portion 70. The groove 63 and the boss 71 utilize the space between the rotating portion 60 and the support portion 70, so that the structure of the entire support assembly is more compact. Compared with some support components that use external complex connections or guiding structures, the embedded grooves 63 and bosses 71 reduce the additional space occupied, so that when the support component is installed on the electronic device or the protective case 2, it will not significantly increase the overall volume of the device or change the coordination of its appearance contour, thereby reducing the risk of component damage or support failure due to loose structure.

[0046] See also Fig.11 , Fig.18 and Fig.19The support assembly of the embodiment of the present application also includes a graduation part 90, which is arranged on the base 50 and is located between the base 50 and the rotating part 60. One of the rotating part 60 and the graduation part 90 is provided with a plurality of first graduation limit structures 91 arranged at intervals along a circular path, and the other is provided with a second graduation limit structure 92, and the second graduation limit structure 92 cooperates with at least one first graduation limit structure 91. The plurality of first graduation limit structures 91 arranged at intervals along the circular path cooperate with the second graduation limit structure 92, and when the rotating part 60 rotates relative to the base 50, the rotation angle can be accurately limited to a specific graduation value. For example, in some scenes with high requirements for angles, such as using a folding machine for professional photography auxiliary support, it is necessary to accurately adjust the shooting angle of the equipment. At this time, the graduation part 90 can accurately adjust the rotation angle to a very small degree range, such as positioning one gear every 5 degrees or 10 degrees, which cannot be achieved by a support assembly without a graduation structure. The cooperation between the first dividing limit structure 91 and the second dividing limit structure 92 in the embodiment of the present application provides a reliable limit for the rotation of the rotating part 60, and rotation deviation beyond the expected range will not easily occur, which effectively prevents the device from slipping or causing viewing and operation inconveniences due to accidental rotation.

[0047] One of the first indexing limit structure 91 and the second indexing limit structure 92 of the embodiment of the present application is a indexing groove 63, and the other is an elastic buckle 931. The elastic buckle 931 has a certain elastic deformation ability. When the rotating part 60 rotates, the elastic buckle 931 will move along the circular path. Once it moves to the position corresponding to the indexing groove 63, it will quickly snap into the groove 63 under the action of its own elastic force. Since the indexing groove 63 is a plurality of fixed positions arranged at intervals along the circular path, the rotation angle of the rotating part 60 can be accurately limited to the angle corresponding to each groove 63, avoiding the arbitrariness and uncertainty of the rotation angle. For example, when using a folding machine for high-precision image or video shooting, it can help users obtain a more stable and standard shooting angle to ensure the consistency of the shooting picture.

[0048] In some examples, in order to facilitate the user to rotate the angle, the part of the elastic buckle 931 that cooperates with the indexing groove 63 and the indexing groove 63 are both smoothly set. The user only needs to gently rotate the rotating part 60, and the elastic buckle 931 will automatically find and snap into the appropriate indexing groove 63. When it is necessary to switch the angle, a certain external force is applied to overcome the elastic force of the elastic buckle 931 to make it disengage from the current indexing groove 63, and then continue to rotate the rotating part 60, and the elastic buckle 931 will be stuck in the next appropriate groove 63. The whole process does not require complicated tools or cumbersome adjustment steps, and the user can quickly switch between different preset angles.

[0049] The elastic buckle 931 cooperates with the indexing groove 63 to produce a mechanically simulated click sound, providing the user with clear and unambiguous operational feedback. In the process of adjusting the angle of the rotating part 60, each click means that the elastic buckle 931 has successfully snapped into a indexing groove 63, that is, the device has been accurately positioned at a specific angle. Auditory feedback allows users to confirm whether the operation is successful by sound alone without having to keep an eye on the angle changes of the device during operation, greatly enhancing the intuitiveness and certainty of the operation. For example, in dim light or when the user's vision is blocked, such as when using a folding machine to watch a video and adjust the angle at night, the click sound can let the user know clearly that the support assembly has stabilized at the appropriate angle, without having to worry about misoperation due to inability to see or uncertainty about whether it is adjusted in place.

[0050] The mechanically simulated click sound can bring a sense of control, similar to the sound of a mechanical switch or precision instrument when it is operated, which makes the user subconsciously feel the high quality and precision of the product, as if they are operating a high-end, professional device. Each click sound is like a positive response to the user's operation, making the entire operation process more ceremonial and interesting, and effectively improving the interactive experience between the user and the supporting components and electronic equipment.

[0051] In some examples, the first indexing stop structure 91 is a magnetic block, and the second indexing stop structure 92 is a magnetic slot. The magnetic block is a small permanent magnet, which is embedded on the surface of the rotating part 60 or the indexing part 90 at intervals along a circular path. When the rotating part 60 rotates, the magnetic block gradually approaches the magnetic slot. Once the magnetic block is aligned with the magnetic slot, an attractive force will be generated between them, and the rotating part 60 will be stably adsorbed at this position to achieve precise positioning of the angle.

[0052] The base 50 of the embodiment of the present application is provided with a mounting boss 51, and the dividing portion 90 includes a dividing ring 93, which is fixedly sleeved on the mounting boss 51, and the inner wall of the dividing ring 93 is matched with the outer wall of the mounting boss 51. During installation, the dividing ring 93 is slowly inserted along the axial direction of the mounting boss 51. During the insertion process, it is necessary to ensure that the inner wall of the dividing ring 93 is in close contact with the outer wall of the mounting boss 51 without obvious gap or skew. The tight fit between the mounting boss 51 and the inner wall of the dividing ring 93 can effectively prevent the dividing ring 93 from shaking, displacement or falling off when subjected to external force. For example, when the support assembly bears the weight of the folding machine and may be subjected to accidental collision or vibration, the stable connection structure between the base 50 and the dividing ring 93 can ensure that the position of the dividing ring 93 remains fixed.

[0053] See also Fig.11 and Fig.16The rotating part 60 of the embodiment of the present application includes a first rotating ring 61 and a second rotating ring 62. The support part 70 is hinged on the first rotating ring 61. The boss 71 is arranged on the support part 70, and the groove 63 is arranged on the second rotating ring 62. The boss 71 is adapted to the inner side of the groove 63. The support part 70 rotates under force, driving the first rotating ring 61 to rotate. The first rotating ring 61 transmits the force to the second rotating ring 62 through the cooperation of the boss 71 and the groove 63. The groove 63 on the second rotating ring 62 can play the role of hiding the hinge axis of the support part 70. Hiding the hinge axis can improve the overall aesthetics of the support assembly and the entire electronic device or protective shell 2. The exposure of the traditional hinge axis often destroys the smoothness and simplicity of the device surface, making the product appearance appear more abrupt and messy. The second rotating ring 62 cleverly shields the hinge shaft, presenting a concise and integrated visual effect. Whether the folder is in a folded state or an unfolded state, its appearance is more refined and harmonious, which meets the aesthetic pursuit of modern consumers for the exquisite and simple appearance of electronic products. The hinge shaft is hidden inside the second rotating ring 62, which can effectively reduce the damage to the hinge shaft caused by external factors. In daily use, the exposed hinge shaft is easily affected by adverse factors such as dust, water vapor, and collision. Dust accumulation may cause the hinge shaft to rotate poorly, water vapor erosion may cause the hinge shaft to rust and corrode, and accidental collision may directly damage the hinge shaft structure. The shielding effect of the second rotating ring 62 forms a relatively closed protective space, reducing these risks.

[0054] In terms of user experience, hiding the hinge axis helps avoid problems such as scratches or pinching caused by the exposed hinge axis. For example, when a user holds or carries a device with the support assembly installed, they will not be injured by accidentally touching the exposed hinge axis, and it also avoids the hinge axis scratching the desktop or other objects when placing the device on a desktop or other flat surface.

[0055] See also Fig. 20 The support assembly of the embodiment of the present application includes a hinge assembly 94, and the hinge assembly 94 includes a first hinge piece 941 and a second hinge piece 942 that are hinged to each other. The first hinge piece 941 is connected to the support portion 70, and the second hinge piece 942 is connected to the first rotating ring 61. The first limiting structure 81 is arranged on the inner side wall of the groove 63, and the second limiting structure 82 is arranged on the side wall of the boss 71. When the support portion 70 is in the storage position that is not turned over and used, since the hinge axis is located between the first rotating ring 61 and the second rotating ring 62, the support portion 70 can be flatly attached to the first rotating ring 61, thereby reducing the space occupied by the support assembly in the non-working state. The storage method of flatly attaching to the first rotating ring 61 effectively prevents the support portion 70 from being damaged by external force extrusion or collision in the non-use state. Due to its tightly fitting state, the support portion 70 is protected by the first rotating ring 61 to a certain extent, reducing the chance of direct contact with external objects.

[0056] See also Fig.21 , a mounting boss 51 is provided on the base 50 of the embodiment of the present application, and the support assembly includes a top cover 95, the top cover 95 is covered on the mounting boss 51, and the top cover 95 includes a first limiting flange 951, and the first limiting flange 951 is covered on the inner side of the first swivel 61. The first limiting flange 951 extends from the edge or a specific position of the top cover 95, and its shape is adapted to the inner contour of the first swivel 61. It can be an annular sheet structure, the inner surface of which is smooth, and it can also have some protrusions, grooves 63 or other geometric features that cooperate with the first swivel 61. When the top cover 95 is covered on the mounting boss 51, the first limiting flange 951 will fit tightly on the inner side of the first swivel 61, playing a multi-faceted role. On the one hand, it can limit the axial movement of the first swivel 61 to prevent the first swivel 61 from falling off. On the other hand, the first limiting flange 951 can also prevent dust, impurities and other foreign objects from entering the rotating area between the first rotating ring 61 and the base 50 to a certain extent, thereby reducing problems such as poor rotation and increased wear caused by the intrusion of foreign objects.

[0057] See also Fig.11 , Fig.14 , Fig.16 and Fig. 22 , the side wall of the second rotating ring 62 of the embodiment of the present application is provided with an outer flange 64, the inner side wall of the base 50 is provided with a first support flange 52 and a second support flange 53 at intervals in the depth direction, and the support assembly also includes an anti-slip portion 96, which is installed on the second support flange 53 and forms a rotation groove with the first support flange 52, and the outer flange 64 is rotatably installed in the rotation groove. The first support flange 52 and the second support flange 53 are arranged at intervals in the depth direction on the inner side wall of the base 50, and their shapes are adapted to the overall structure of the base 50, generally in the form of an annular or partially annular sheet-like protrusion. The anti-slip portion 96 is installed on the base, and its installation method can be a snap connection, a threaded connection or other reliable fixing methods. When the anti-slip portion 96 is installed in place, a rotation groove of a specific width and depth is formed between it and the first support flange 52. The width of the rotation groove is slightly larger than the thickness of the outer flange 64 of the second rotating ring 62, so that the outer flange 64 can be smoothly inserted into it and rotated. During the rotation process, the first support flange 52 and the anti-slip portion 96 limit the outer flange 64 of the second rotating ring 62 from above and below to prevent the outer flange 64 from slipping out of the rotation groove, thereby ensuring that the second rotating ring 62 can stably rotate relative to the base 50 without displacement or separation. The above arrangement forms a relatively closed space between the various components of the support assembly, which can prevent foreign objects such as dust and impurities from entering the rotation area to a certain extent, and reduce the problems of increased wear of the rotating part 60 and unsmooth rotation caused by the intrusion of foreign objects.

[0058] See also Fig.11 As shown, a recessed part is provided on the side of the first rotating ring 61 close to the base 50 in the embodiment of the present application, the edge of the indexing part 90 is located in the recessed part, and the first indexing stop structure 91 is provided on the side of the edge of the indexing part 90 away from the base 50. The first indexing stop structure 91 is provided on the side of the edge of the indexing part 90 away from the base 50, and while realizing the precise angle control function of the rotating part 60, the spatial height requirement of the entire assembly in the vertical direction is not increased. This enables the support assembly to maintain a relatively compact structural form while ensuring the precise angle adjustment function.

[0059] See also Fig.15 The support portion 70 of the embodiment of the present application is a support ring, and its annular structure naturally forms a space for finger operation. When it is necessary to move, adjust or pick up an electronic device equipped with the support assembly, the user can easily pass his fingers through the support ring. For example, when holding a folding machine, passing the fingers through the support ring can provide additional gripping points and fulcrums, making the device more stable in the hand and reducing the risk of damage to the device due to accidental slipping. Especially for some larger or heavier folding machine models, the way of inserting fingers into the support ring can greatly improve the convenience and safety of handheld operation.
