Description

Technical Field

[0001] The present application relates to the field of electronic technology, and in particular to a bracket, a housing assembly, and a terminal device assembly. Background Art

[0002] With the development of technology and user needs, electronic devices such as foldable mobile phones have been widely used in people's lives.

[0003] To improve user comfort during extended use of electronic devices such as foldable phones, current foldable phones feature a stand on one side of the back cover. This provides both lateral and vertical support for the phone. When the foldable phone is supported laterally on a surface using the existing stand, the stand provides stable support in the middle of the phone's back cover. However, when the phone is flattened and supported vertically on a surface using the stand, it may become unstable.

[0004] How to ensure that the bracket can provide vertical and stable support for the foldable mobile phone in the flat state has become a technical problem to be solved. Summary of the Invention

[0005] The present application provides a bracket, a shell assembly and a terminal device assembly, wherein the bracket is conducive to achieving stable support for the terminal device in different placement states.

[0006] In a first aspect, an embodiment of the present application provides a bracket, which is applied to a protective case of a terminal device component. The bracket includes:

[0007] A mounting piece, which is used to be arranged on the back of the protective shell;

[0008] A connecting plate, the plane of the connecting plate is parallel to the back of the protective shell, and the connecting plate is rotatably arranged on the mounting piece, and

[0009] The support plate is rotatably connected to one end of the connecting plate. The support plate can rotate relative to the connecting plate and form an angle relative to the back of the protective shell.

[0010] In the embodiment of the present application, the mounting member and the connecting plate are arranged in the bracket. Since the mounting member is used to be arranged on the back of the protective shell of the terminal device, the plane on which the connecting plate is located is parallel to the back of the protective shell. The connecting plate is rotatably arranged on the mounting member so that the connecting plate can realize the assembly of the bracket on the back of the protective shell through the mounting member, thereby supporting the protective shell of the terminal device component through the bracket. When the long side of the protective shell and the end of the support plate away from the connecting plate are supported on the placement surface, or when the wide side of the protective shell and the end of the support plate away from the connecting plate are supported on the placement surface, the support plate can be supported on the back of the protective shell, which is conducive to achieving stable support for the terminal device component. The terminal device assembly includes a terminal device. When the terminal device is a folding device, the wide side of the protective shell and the end of the support plate away from the connecting plate are supported on the placement surface, and the folding device is in the unfolded state. Since the connecting plate is rotatably set on the mounting part, and the support plate is rotatably connected to one end of the connecting plate, at this time, the connecting plate can be rotated to adjust the support position of the end of the support plate connected to the connecting plate on the back of the protective shell, thereby adjusting the support center of gravity of the bracket relative to the overall center of gravity of the terminal device to avoid the support center of gravity seriously deviating from the overall center of gravity of the terminal device, which is conducive to achieving stable support of the terminal device by the bracket.

[0011] In some optional embodiments, the middle part of the connecting plate is rotatably arranged on the mounting piece. On the one hand, the connecting plate can be rotated around its own middle part relative to the mounting piece, thereby changing the support position of the end of the support plate connected to the connecting plate on the back of the protective shell. On the other hand, it can also enable the connecting plate to have a smaller rotation force arm to reduce the force applied to the middle part of the connecting plate when the bracket is stably supported on the back of the protective shell, thereby reducing the probability of damage and deformation of the connecting plate.

[0012] In some optional embodiments, the mounting member is configured to be disposed in the middle of the back side of the protective shell; the support plate has a connecting end rotatably connected to the connecting plate, and when the support plate forms an angle with respect to the back side of the protective shell, the support plate is supported on the back side of the protective shell via the connecting end, and the protective shell has a long side and a wide side;

[0013] The connecting plate rotates relative to the mounting member to enable the bracket to be in a first supporting posture and a second supporting posture;

[0014] When the bracket is in the first supporting posture, the vertical projection of the connecting end on the wide side is located in the middle of the wide side, and the length direction of the connecting plate is parallel to the long side of the protective shell;

[0015] When the bracket is in the second supporting posture, the vertical projection of the connecting end on the wide side is located at the asymmetric center of the wide side, and the length direction of the connecting plate is perpendicular to the long side of the protective shell.

[0016] In this way, since the mounting member is used to be set in the middle of the back side of the protective shell, and the middle part of the connecting plate is rotated to be set on the mounting member, in order to meet the aesthetic requirements of the bracket on the protective shell, the connecting plate can also be assembled in the middle part of the back side of the protective shell through the mounting member. In addition, when the bracket is in the first supporting posture, and the long side of the protective shell and the end of the support plate away from the connecting plate are supported on the placement surface, or when the wide side of the protective shell and the end of the support plate away from the connecting plate are supported on the placement surface, the support plate can be supported in the middle part of the wide side of the protective shell, which is conducive to achieving stable support for the terminal device. In addition, when the wide side of the protective shell and the end of the support plate away from the connecting plate are supported on the placement surface, and the folding device is in the unfolded state, the support center of gravity of the bracket can be adjusted relative to the center of gravity of the terminal device by rotating the connecting plate to avoid the support center of gravity from seriously deviating from the center of gravity of the terminal device, thereby facilitating stable support for the terminal device in the flattened state.

[0017] In some optional embodiments, when the bracket is in the first supporting posture, the vertical projection of the connecting end on the long side is located in the middle of the long side, so that the long side of the protective shell and the end of the support plate away from the connecting plate are supported on the placement surface, or when the wide side of the protective shell and the end of the support plate away from the connecting plate are supported on the placement surface, the support plate can be supported on the long side and the middle of the wide side of the protective shell, which is conducive to achieving stable support for the terminal device.

[0018] In some optional embodiments, the end surface of the connecting end is an inclined surface inclined toward one side of the center of the support plate;

[0019] And / or, a side of the connecting plate facing the protective shell has at least one friction plate, and the friction plate is located on a side of the mounting component.

[0020] The provision of the inclined surface in the present application not only prevents the support plate from scratching the protective shell during rotation relative to the connecting plate, but also prevents the protective shell from interfering with the rotation of the support plate. The provision of the friction plate in the present application prevents the connecting plate from being scratched in the thickness direction of the protective shell during rotation relative to the mounting member.

[0021] In some optional embodiments, the length of the connecting plate and the width of the protective shell satisfy the conditional formula: L+2L×sina=2S+C,

[0022] Among them, L is half the length of the connecting plate, a is the angle between the direction perpendicular to the plane of the connecting plate and the length direction of the supporting plate when the bracket is in the second supporting posture, S is half the length of the wide side of the protective shell, and C is the tolerance.

[0023] In this way, by limiting the length of the connecting plate, not only can the support part be supported on the side of the protective shell facing the second shell in the length direction, but also the end of the connecting plate can be prevented from extending out of the protective shell, affecting the aesthetics of the shell assembly and the terminal device.

[0024] In some optional embodiments, the mounting member has a rotating surface, the central axis of the rotating surface is perpendicular to the back of the protective shell, and the middle portion of the connecting plate is rotatably connected to the mounting member through the rotating surface so that the middle portion of the connecting plate can rotate relative to the mounting member around the central axis of the rotating surface.

[0025] In some optional embodiments, the mounting member has a rotation groove, and the groove wall of the rotation groove forms a rotation surface;

[0026] The middle part of the connecting plate is provided with a rotating part extending into the rotating groove, and the outer wall of the rotating part is in rotational contact with the rotating surface so that the middle part of the connecting plate is rotatably arranged on the mounting piece.

[0027] In some optional embodiments, the shell assembly further includes a fixing member connected to the connecting plate, and the fixing member is relatively fixed to the protective shell in the central axis direction of the rotating surface, which is conducive to the assembly of the connecting plate on the protective shell.

[0028] In some optional embodiments, the protective shell has a accommodating cavity, the side of the accommodating cavity facing the connecting plate has a mounting hole, the aperture of the mounting hole is smaller than the inner diameter of the accommodating cavity; the fixing member is arranged in the accommodating cavity, and the rotating part extends into the mounting hole and is connected to the fixing member.

[0029] The provision of the accommodating cavity thus facilitates the assembly of the fixing member within the protective shell. Furthermore, since the rotating portion extends into the mounting hole to connect with the fixing member, the fixing member not only facilitates the assembly of the connecting plate to the protective shell but also limits the position of the connecting plate in the central axial direction of the rotating surface.

[0030] In some optional embodiments, the fixing member is an annular member, the rotating portion passes through the center hole of the fixing member, and is riveted to the fixing member, so as to achieve stable assembly of the connecting plate on the protective shell without affecting the rotation of the middle part of the connecting plate on the mounting member, so that the middle part of the connecting plate can rotate relative to the mounting member.

[0031] In some optional embodiments, the connecting plate has an assembly groove on a side facing the mounting member, and the mounting member is located in the assembly groove, so that while the mounting member is assembled in the connecting plate, it can also facilitate the thinning of the housing assembly and the terminal device.

[0032] In some optional embodiments, the support plate can rotate relative to the connecting plate and cover the connecting plate, so that when the terminal device does not need to be supported by the bracket, the support plate can cover the connecting plate and shield the connecting plate, thereby increasing the portability and aesthetics of the terminal device.

[0033] In some optional embodiments, the mounting member is a disc-shaped structure having a rotating surface, a blocking block is provided circumferentially of the mounting member, and the connecting plate has at least one limiting group, the limiting group includes two limiting protrusions extending on the connecting plate toward one side of the mounting member; the blocking block is located between the two limiting protrusions to block the limiting protrusion and limit the position of the connecting plate relative to the protective shell.

[0034] In this way, during the rotation of the connecting plate relative to the mounting member, the cooperation between the blocking block and the two limiting protrusions can increase the reverse force of the connecting plate, thereby preventing the connecting plate from rotating excessively relative to the mounting member.

[0035] In some optional embodiments, the blocking block is located on the rotation path of the limiting protrusion, the two facing surfaces of the two limiting protrusions are set at an angle, and the angle formed by the two surfaces is the same as the preset rotation angle of the connecting plate relative to the mounting member, so that the blocking part and the two limiting protrusions can cooperate to achieve the limitation of the connecting plate in the first supporting posture and the second supporting posture.

[0036] In some optional embodiments, the shell assembly further includes a damping unit, which abuts between the mounting member and the connecting plate to provide rotational damping of the connecting plate relative to the mounting member, so that the bracket can achieve stable support for the terminal device in different supporting postures.

[0037] In some optional embodiments, the damping unit includes at least one of a gasket and an elastic group;

[0038] The gasket is located on a side of the mounting piece facing the connecting plate and is sandwiched between the mounting piece and the connecting plate;

[0039] The elastic group includes an elastic member, which abuts against the circumferential side wall of the mounting member and is connected to the connecting plate.

[0040] Thus, when the connecting plate rotates relative to the mounting member, the friction generated by the mutual movement between the gasket, the mounting member, and the connecting plate can provide a portion of the rotational damping for the bracket. Correspondingly, when the connecting plate rotates relative to the mounting member, the friction generated by the mutual movement between the elastic member and the mounting member can provide another portion of the rotational damping for the bracket.

[0041] In some optional embodiments, the gasket is an annular gasket, and the rotating portion of the connecting plate passes through the center hole of the gasket and is in rotational contact with the rotating surface of the mounting member, so that while the gasket provides a portion of rotational damping for the bracket, it can also facilitate the middle portion of the connecting plate to be rotated and set on the mounting member through the rotating surface.

[0042] In some optional embodiments, the damping unit includes at least two elastic groups, and the at least two elastic groups are evenly distributed around the circumference of the mounting member, so that the at least two elastic groups abut against the circumferential side walls of the mounting member in different directions, thereby providing rotational damping for the connecting plate and making the rotation of the connecting plate on the mounting member more stable.

[0043] In some optional embodiments, the elastic member includes a first elastic member, which is connected to the connecting plate and abuts against the circumferential side wall of the mounting member, so that when the connecting plate rotates relative to the mounting member, a certain friction force is generated between the first elastic member and the mounting member due to the relative movement, thereby providing rotational damping for the bracket.

[0044] In some optional embodiments, the first elastic member has a fixed section and an abutment section, the abutment section is adapted to the shape of the circumferential side wall of the mounting member and abuts against the circumferential side wall of the mounting member; the fixed section is connected to the end of the abutment section and is connected to the connecting plate.

[0045] In this way, while the first elastic member is connected to the connecting plate through the fixing section, the first elastic member can also be brought into contact with the circumferential side wall of the mounting member through the contact section.

[0046] In some optional embodiments, the first elastic member is clamped between the mounting member and the connecting plate, so that the first elastic member can be assembled on the connecting plate while facilitating the first elastic member to abut against the circumferential side wall of the mounting member.

[0047] In some optional embodiments, the mounting member has a snap-fitting portion, and the connecting plate has a snap-fitting portion, and the snap-fitting portion and the snap-fitting portion are arranged opposite to each other. When the bracket is in the first supporting posture and the second supporting posture, the snap-fitting portion and the snap-fitting portion are snapped together, so that the connecting plate will produce a certain sense of frustration when it is rotated to the specified position, thereby prompting that the bracket has been rotated into place.

[0048] In some optional embodiments, the snap-fitting portion is located on the side of the mounting member facing the connecting plate, or the snap-fitting portion is located on the side of the blocking block in the mounting member facing the limiting protrusion in the connecting plate. In this way, while achieving the snap-fitting of the snap-fitting portion and the connecting portion, the setting positions of the snap-fitting portion and the connecting portion can be made more diversified.

[0049] In some optional embodiments, the mounting member is provided with a step on a surface facing the connecting plate, the step including a step surface and a step side wall provided at an angle to the step surface, the abutting section is located on the step surface and abuts against the step side wall, the step side wall forms a circumferential side wall of the mounting member, so as to ensure that the abutting section abuts against the circumferential side wall of the mounting member while preventing the first elastic member from falling off from the bracket during use.

[0050] In some optional embodiments, the mounting member has a snap-fitting portion, and the abutting section has a snap-fitting portion. The snap-fitting portion and the snap-fitting portion are arranged opposite to each other. When the bracket is in the first supporting posture and the second supporting posture, the snap-fitting portion and the snap-fitting portion are snapped together, so that the connecting plate will produce a certain sense of frustration when it is rotated to the specified position, thereby prompting that the bracket has been rotated into place.

[0051] In some optional embodiments, the elastic member includes a second elastic member, and the elastic group also includes an abutment block adapted to the shape of the circumferential side wall of the mounting member, the abutment block abuts against the circumferential side wall of the mounting member, and the second elastic member abuts between the abutment block and the connecting plate.

[0052] In this way, the second elastic member can exert a certain elastic force on the abutment block, causing the abutment block to abut against the circumferential side wall of the mounting member, thereby realizing indirect abutment between the second elastic member and the circumferential side wall of the mounting member, so that when the connecting plate rotates relative to the mounting member, friction will be generated between the abutment block and the mounting member due to the relative movement, providing rotation damping for the bracket.

[0053] A second aspect of an embodiment of the present application provides a housing assembly for use with a terminal device. The housing assembly includes a protective shell and any of the aforementioned brackets. The protective shell is configured to cover the back of the terminal device, the back of the protective shell being parallel to the back of the terminal device. The bracket is mounted to the middle portion of the back of the protective shell via a mounting member in the bracket.

[0054] The present application sets a protective shell and a bracket in a shell assembly. Since the protective shell cover is set on the back of the terminal device, and the bracket is installed in the middle of the back of the protective shell through a mounting piece, so that the bracket can be assembled on the back of the terminal device through the protective shell, while meeting the aesthetic requirements of the bracket on the protective shell, when the long side of the protective shell and the end of the support plate in the bracket away from the connecting plate in the bracket are supported on the placement surface, or when the wide side of the protective shell and the end of the support plate away from the connecting plate are supported on the placement surface, the support plate can be supported on the back of the protective shell, which is conducive to achieving stable support for the terminal device. In addition, since the connecting plate in the bracket is rotatably set on the mounting piece, when the wide side of the protective shell and the end of the support plate away from the connecting plate are supported on the placement surface, and the terminal device is in the unfolded state of a folding device, the support plate can also be supported on the terminal device near the center of gravity of the entire terminal device through the rotation of the connecting plate, which is conducive to achieving stable support of the support plate terminal device. Therefore, the shell assembly of the present application can be conducive to achieving stable support for terminal devices in different placement states.

[0055] The third aspect of the embodiment of the present application also provides a terminal device assembly, which includes a terminal device and the above-mentioned shell assembly. The terminal device includes a shell. The protective shell in the shell assembly is used to cover at least part of the structure of the shell, which is conducive to achieving stable support for the terminal device in different placement states through the shell assembly.

[0056] In some optional embodiments, the housing includes a first housing and a second housing that are rotatably connected, and the protective shell cover is provided on the back side of the first housing;

[0057] The support plate has a connecting end rotatably connected to the connecting plate. When the support plate forms an angle with respect to the back of the protective shell, the support plate is supported on the back of the protective shell by the connecting end. The connecting plate rotates relative to the mounting member to enable the bracket to be in a first supporting posture and a second supporting posture.

[0058] The terminal device has a first placement state and a second placement state. When the terminal device is in the first placement state, the long side of the protective shell is parallel to the placement surface, and the bracket is supported on the back of the protective shell in a first supporting posture. In the first supporting posture, the vertical projection of the connecting end of the support plate in the bracket on the wide side of the protective shell is located in the middle of the wide side of the protective shell, and the end of the support plate away from the connecting end is supported on the placement surface, so as to achieve stable support for the terminal device in the first placement state in both the folded state and the flattened state.

[0059] When the terminal device is in the second placement state, the second shell and the first shell are located in the same plane, the long side of the protective shell is arranged at an angle to the placement surface, and the bracket is supported on the back of the protective shell in the second support posture. In the second support posture, the vertical projection of the connecting end on the wide side is located on the side of the wide side facing the second shell, and the end of the support plate away from the connecting end is supported on the placement surface. The second shell and the first shell are located in the same plane by rotating the second shell relative to the side of the first shell facing the protective shell.

[0060] In this way, when the bracket is supported on the back of the protective shell in the second supporting posture, it can achieve stable support for the terminal device in the second placement state in the flat state.

[0061] In some optional embodiments, in the first supporting posture, the vertical projection of the connecting end on the long side of the protective shell is located in the middle of the long side, so that when the bracket is supported on the back of the protective shell in the first supporting posture, the support plate can be supported in the middle of the long side and the wide side of the protective shell, which is conducive to achieving stable support for the terminal device in the first placement state and in the folded state in the second placement state.

[0062] A fourth aspect of an embodiment of the present application provides a terminal device component, the terminal device component including:

[0063] Terminal device, the terminal device includes a back cover;

[0064] Bracket, the bracket includes:

[0065] A mounting piece, the mounting piece is used to be arranged in the middle of the back side of the rear cover;

[0066] The connecting plate is located on a plane parallel to the back of the rear cover, and the middle of the connecting plate is rotated and arranged on the mounting piece.

[0067] And a support plate, the support plate is rotatably connected to one end of the connecting plate, and the support plate can rotate relative to the connecting plate and form an angle relative to the back surface of the rear cover.

[0068] In the present application, the bracket is provided in the terminal device assembly. Since the mounting member in the bracket is installed in the middle of the back of the back cover, and the middle portion of the connecting plate is rotatably mounted on the mounting member, the bracket can be installed on the terminal device while meeting the aesthetic requirements of the bracket on the terminal device. When the long side of the back cover and the end of the support plate away from the connecting plate are supported on the placement surface, or when the wide side of the back cover and the end of the support plate away from the connecting plate are supported on the placement surface, the support plate can be supported on the back of the back cover, which is conducive to achieving stable support for the terminal device. When the terminal device is a folding device, the wide side of the back cover and the end of the support plate away from the connecting plate are supported on the placement surface, and the folding device is in the unfolded state, since the connecting plate is rotatably mounted on the mounting member and the support plate is rotatably connected to one end of the connecting plate, the support position of the end of the support plate connected to the connecting plate on the back of the back cover can be adjusted by rotating the connecting plate, so that the support plate can be supported on the terminal device near the center of gravity of the entire terminal device, thereby facilitating the bracket to provide stable support for the terminal device in different placement states.

The center of gravity of a regular object with uniform density is its geometric center. When an object has uniform mass, its center of gravity and center coincide; when an object has uneven mass, the two are not at the same point.

[0111] In order to improve people's comfort when using electronic devices such as foldable mobile phones for a long time, reference Figure 2aAs shown, the first housing 2111a includes a back cover 2113a, which covers the battery of the foldable phone and is located on the back of the first housing 2111a. A protective shell 1a is typically provided on one side of the back cover 2113a in foldable phones. The protective shell 1a can be placed on the back of the back cover 2113a. The protective shell 1a has a bracket 2a, which can be supported in the middle portion (center area) of the protective shell 1a, thereby providing both lateral and vertical support for the foldable phone.

[0112] refer to Figure 2a As shown, the bracket 2 a may include a fixing portion 28 and a supporting portion 29 . The fixing portion 28 is installed at the middle portion of the back side of the protective shell 1 a , and the supporting portion 29 is connected to the end of the fixing portion 28 .

[0113] refer to Figure 2a As shown, when the foldable phone is placed horizontally on a storage surface (not shown in the figure), the support portion 29 can provide stable horizontal support in the middle of the protective case 1a, thereby providing lateral support for the foldable phone on the storage surface. In this case, the foldable phone can be in a flat state or a folded state. When the foldable phone is placed horizontally on the storage surface, the long side 14a of the protective case 1a is parallel to the storage surface.

[0114] Figure 2b The figure shows a schematic diagram of the structure of a foldable mobile phone when supported vertically in the related art.

[0115] refer to Figure 2b As shown, when the foldable phone is flattened and placed vertically on a placement surface, with the appropriate angle between the support portion 29 and the protective case 1a, the support portion 29 can be vertically supported on the protective case 1a, thereby achieving vertical support for the foldable phone on the placement surface. In this case, the long side 14a of the protective case 1a is perpendicular to the placement surface. Because the center of gravity of the foldable phone is not in the same position when flattened and folded, when the foldable phone is flattened and vertically supported on the placement surface by the bracket 2a, the support center of gravity Q1 of the bracket 2a is significantly eccentric relative to the center of gravity Q of the foldable phone, which may cause unstable support for the foldable phone.

[0116] How to ensure that the bracket 2 can provide vertical and stable support for the foldable mobile phone has become a technical problem to be solved.

[0117] In view of this, an embodiment of the present application provides a shell assembly, which, through the setting of the bracket in the shell assembly, can adjust the supporting center of gravity of the bracket to the corresponding position on the shell assembly, which is conducive to achieving vertical and stable support for the terminal device in a flattened state.

[0118] Figure 3 The figure shows the assembly diagram of the housing component on the terminal device. Figure 4 The exploded view of the housing assembly on the terminal device is shown.

[0119] refer to Figure 3 and Figure 4 As shown, the housing assembly 100 includes a protective shell 1, which is used to cover the back of the terminal device 210. The back of the protective shell 1 is parallel to the back of the terminal device 210 to facilitate the assembly of the housing assembly 100 on the back of the terminal device 210.

[0120] The terminal device of the present application may be a foldable mobile phone, a laptop computer, a tablet, or other large-sized terminal products whose center of gravity is eccentric to the center of gravity of the entire device when the center of gravity is placed in a vertical position.

[0121] The structure of the housing assembly of the embodiment of the present application is further explained below using a foldable mobile phone as an example.

[0122] refer to Figure 3 and Figure 4 As shown, the terminal device 210 includes a first shell 2111 and a second shell 2114, and the first shell 2111 and the second shell 2114 are rotatably connected to form the shell 201 of the terminal device 210. The protective shell 1 is used to cover the back of the first shell 2111, and the back of the protective shell 1 is parallel to the back of the first shell 2111. Figure 4 As shown, the first housing 2111 may include a first middle frame 2112 and a back cover 2113. The back cover 2113 is placed on the first middle frame 2112 to form the first housing 2111 with a receiving cavity. The receiving cavity can be used to accommodate components such as the circuit board, battery, and camera module of the terminal device 210. The back cover 2113 can serve as the back side of the first housing 2111, and the protective shell 1 is used to cover the back side of the back cover 2113.

[0123] To enable the camera module's camera function, a light-entry area (not shown) is provided on the back cover 2113. A protective shell 1 can be placed over the back cover 2113, and a relief hole 13 is provided in the light-entry area of ​​the back cover 2113 to prevent the protective shell 1 from affecting the light entering the light-entry area and thus affecting the camera module's camera function.

[0124] Continue to refer Figure 4As shown, the second housing 2114 may include a second middle frame 2115, which is rotatably connected to the first middle frame 2112. The flexible display screen (not shown in the figure) of the terminal device 210 can be set on the same side of the first middle frame 2112 and the second middle frame 2115 to form the front of the terminal device 210. The flexible display screen (not shown in the figure) and the back cover 2113 are located on opposite sides of the first middle frame 2112, and the back cover 2113 can also form the back of the terminal device 210. In some embodiments, another display screen (not shown in the figure) is further provided on the side of the second middle frame 2115 facing away from the flexible display screen 202. In this application, the structure of the terminal device 210 is not further limited.

[0125] refer to Figure 4 Combined with Figure 3 As shown, the shell assembly 100 also includes a bracket 2, which is installed on the back of the protective shell 1, so that the shell assembly 100 can support the terminal device 210 through the bracket 2, and at the same time, it can also adjust the position of the support center of gravity on the back of the terminal device 210, which is conducive to achieving vertical and stable support of the terminal device 210 in a flattened state.

[0126] The structure of the bracket 2 provided in the present application is further described below in conjunction with the accompanying drawings and embodiments.

[0127] Continue to refer Figure 4 As shown, the bracket 2 of the present application can be applied to the protective shell 1 of the terminal device assembly 200. In some embodiments, the terminal device assembly 200 may include a terminal device 210 and a shell assembly 100, and the protective shell 1 in the shell assembly 100 can be covered on at least a portion of the structure of the shell 201 in the terminal device 210.

[0128] Alternatively, in other embodiments, the terminal device assembly 200 may further include a terminal device 210 and a bracket 2, the terminal device 210 includes a back cover 2113, and the bracket 2 may be installed in the middle of the back of the back cover 2113. In this case, the back cover 2113 may also be regarded as the protective shell 1 in the terminal device 210.

[0129] The structure of the bracket 2 of the present application is further described below by taking the terminal device assembly 200 including the terminal device 210 and the housing assembly 100 as an example.

[0130] like Figure 4As shown in FIG, the bracket 2 includes a mounting member 23. The mounting member 23 is configured to be mounted on the back of the protective case 1. The bracket 2 also includes a connecting plate 21. The plane on which the connecting plate 21 is located is parallel to the back of the protective case 1, and the connecting plate 21 is rotatably mounted on the mounting member 23. This allows the connecting plate 21 to be mounted on the back of the protective case 1 via the mounting member 23, allowing the bracket 2 to be mounted on the back of the protective case 1 via the connecting plate 21 while also allowing the connecting plate 21 to rotate relative to the mounting member 23 and the protective case 1.

[0131] Continue to refer Figure 4 As shown, the bracket 2 further includes a support plate 22 , which is rotatably connected to one end of the connecting plate 21 . The support plate 22 can rotate relative to the connecting plate 21 and form an angle relative to the back of the protective shell 1 .

[0132] In this way, when the bracket 2 is assembled on the back of the protective shell 1 through the connecting plate 21, since the support plate 22 can rotate relative to the connecting plate 21 and form an angle relative to the back of the protective shell 1, it can be supported on the back of the protective shell 1 through the support plate, thereby achieving support for the terminal device component 200.

[0133] Figure 5a and Figure 5b The schematic diagrams of the structure of the shell assembly in the first supporting posture and the second supporting posture are respectively illustrated.

[0134] refer to Figure 5a As shown, when the long side 14 of the protective shell 1 and the end of the support plate 22 away from the connecting plate 21 are supported on a placement surface (not shown in the figure), or when the wide side 15 of the protective shell 1 and the end of the support plate 22 away from the connecting plate 21 are supported on the placement surface, the support plate 22 can be supported on the back of the protective shell 1, which is conducive to achieving stable support for the terminal device components.

[0135] refer to Figure 5b Combined with Figure 4As shown, the terminal device assembly includes a terminal device. When the terminal device is a folding device (such as a folding mobile phone), the wide side 15 of the protective shell 1 and the end of the support plate 22 away from the connecting plate 21 are supported on the placement surface, and the folding device is in the unfolded state. Since the connecting plate 21 is rotatably set on the mounting member 23, and the support plate 22 is rotatably connected to one end of the connecting plate 21, at this time, the connecting plate 21 can be rotated. Since the support plate 22 is connected to the end of the connecting plate 21, as the connecting plate 21 rotates, the support plate 22 also rotates accordingly, so that the support plate 22 can be supported at a different position on the back of the protective shell 1 compared to before rotation. Therefore, by adjusting the support position of the end of the support plate 22 connected to the connecting plate 21 on the back of the protective shell 1, the support center of gravity of the bracket 2 is adjusted relative to the center of gravity of the entire terminal device 210 to avoid the support center of gravity seriously deviating from the center of gravity of the entire terminal device 210, which is conducive to achieving stable support of the terminal device 210 by the bracket 2.

[0136] Therefore, the bracket 2 of the present application can facilitate stable support of the terminal device 210 in different placement states through the rotation of the connecting plate 21.

[0137] Continue to refer Figure 5b Combined with Figure 4 As shown, in some embodiments, the middle portion of the connecting plate 21 can be rotatably disposed on the mounting member 23. The middle portion of the connecting plate 21 can be understood as the middle region of the connecting plate 21, rather than the edge region of the connecting plate 21. The middle region of the connecting plate 21 may include the symmetry center of the connecting plate 21. There is a preset distance between one side of the edge region of the connecting plate 21 close to the middle region and the outermost edge of the connecting plate 21. For example, the preset distance may be one-third, one-quarter, or one-fifth of the length of the connecting plate 21. The direction in which the length of the connecting plate 21 is located can be referred to Figure 4 in the Y direction.

[0138] Since the middle part of the connecting plate 21 is rotatably arranged on the mounting member 23, the connecting plate 21 can rotate around its own middle part relative to the mounting member 23, thereby changing the supporting position of the end of the support plate 22 connected to the connecting plate 21 on the back of the protective shell 1.

[0139] Since the bracket 2 is stable and supported on the back of the protective shell 1 for a long time, if the rotation force arm of the connecting plate 21 is too large, the rotating part where the connecting plate 21 is connected to the mounting member 23 will be subjected to a large force for a long time. Under the action of this force, the connecting plate 21 will be easily damaged and deformed, affecting the assembly of the bracket 2 on the back of the protective shell 1.

[0140] The present application enables the connecting plate 21 to have a smaller turning force arm by rotating the middle part of the connecting plate 21 to be set on the mounting part 23, so as to reduce the force exerted on the middle part of the connecting plate 21 when the bracket 2 is stably supported on the back of the protective shell 1, thereby reducing the probability of damage and deformation of the connecting plate. The middle part of the connecting plate 21 can be used as the rotating part of the connecting plate. The turning force arm of the connecting plate 21 can be understood as the distance between the center of symmetry of the middle part of the connecting plate and the end face of one end where the connecting plate 21 is connected to the support plate 22. For example, the turning force arm of the connecting plate 21 can be half the length of the connecting plate 21.

[0141] If there is no requirement for the damage and deformation probability of the connecting plate 21 , in some embodiments, the edge area of ​​the connecting plate 21 can also be rotatably disposed on the mounting member 23 .

[0142] The structure of the bracket 2 of the present application will be further described below by taking the example of the middle portion of the connecting plate 21 being rotatably mounted on the mounting member 23 .

[0143] like Figure 4 As shown in , in some embodiments, the mounting member 23 can be disposed in the middle of the back of the protective case 1. The middle of the back of the protective case 1 can be the middle region of the back of the protective case 1, which can be the asymmetric center of the back of the protective case 1, rather than the edge region of the back of the protective case 1. Specifically, a side of the edge region of the protective case 1 close to the middle region has a predetermined distance from the outermost edge of the protective case 1. For example, the predetermined distance can be one-third, one-quarter, or one-fifth of the length of the wide side 15.

[0144] Since the mounting member 23 can be used to be set in the middle of the back side of the protective shell 1, and the middle part of the connecting plate 21 is rotatably set on the mounting member 23, on the basis of meeting the aesthetic requirements of the bracket 2 on the protective shell 1, the connecting plate 21 can also realize the assembly of the bracket 2 in the middle of the back side of the protective shell 1 through the mounting member 23.

[0145] refer to Figure 5a and Figure 5b As shown, the support plate 22 has a connecting end 221 that is rotatably connected to the connecting plate 21. When the support plate 22 forms an angle with respect to the back of the protective shell 1, the support plate 22 is supported on the back of the protective shell 1 through the connecting end 221. The protective shell 1 has a long side 14 and a wide side 15. The rotation of the connecting plate 21 relative to the mounting member 23 can enable the bracket 2 to be in a first supporting posture and a second supporting posture. In this way, when the connecting plate 21 rotates to different directions relative to the mounting member 23, the support plate 22 also rotates synchronously with the connecting plate 21, so that when the bracket 2 is in the first supporting posture and the second supporting posture, the support plate 22 can be supported at different positions of the protective shell 1, thereby achieving the purpose of adjusting the support center of gravity of the bracket 2.

[0146] refer to Figure 5a As shown, when the bracket 2 is in the first supporting posture, the vertical projection of the connecting end 221 on the wide side 15 is located in the middle of the wide side 15, and the length direction of the connecting plate 21 is parallel to the long side of the protective shell 1. Figure 5b As shown, when the bracket 2 is in the second supporting posture, the vertical projection of the connecting end 221 on the wide side 15 is located at the asymmetric center of the wide side 15, and the length direction of the connecting plate 21 is perpendicular to the long side 14 of the protective shell 1.

[0147] Because the connecting plate 21 rotates about its middle portion relative to the mounting member 23 and the protective case 1, while ensuring that the bracket 2 is always located in the middle portion of the protective case 1, the bracket 2 in the first supporting posture can also facilitate stable support of the terminal device 210 in at least one placement state. Specifically, when the bracket 2 is in the first supporting posture, and when the long side 14 of the protective case 1 and the end of the support plate 22 away from the connecting plate 21 are supported on the placement surface, or when the wide side 15 of the protective case 1 and the end of the support plate 22 away from the connecting plate 21 are supported on the placement surface, the support plate 22 can be supported in the middle portion of the wide side 15 of the protective case 1, which is conducive to achieving stable support for the terminal device 210 in at least one placement state.

[0148] refer to Figure 5b As shown, as the structure and placement state of the terminal device 210 change, for example, when the terminal device 210 is a folding device (such as a folding mobile phone), the wide side 15 of the protective shell 1 and the end of the support plate 22 away from the connecting plate 21 are supported on the placement surface, and the folding device is in the unfolded state, the connecting plate 21 can be rotated relative to the mounting member 23 to adjust the position of the support center of gravity of the bracket 2 relative to the center of gravity of the terminal device 210, so as to avoid the terminal device 210 being in a flattened state and supported vertically on the placement surface. The center of gravity of the support and the center of gravity of the terminal device 210 are seriously deviated, which is conducive to achieving stable vertical support of the terminal device 210 in the flattened state.

[0149] like Figure 5a As shown, when the bracket 2 is in the first supporting posture, the vertical projection of the connecting end 221 on the long side 14 is located in the middle of the long side 14, so that when the long side 14 of the protective shell 1 and the end of the support plate 22 away from the connecting plate 21 are supported on the placement surface, or when the wide side 15 of the protective shell 1 and the end of the support plate 22 away from the connecting plate 21 are supported on the placement surface, the support plate 22 can be supported on the middle of the long side 14 and the wide side 15 of the protective shell 1 (the center of the back of the protective shell 1), which is conducive to achieving stable support for the terminal device 210.

[0150] The following further describes how the bracket 2 supports the terminal device 210 in different supporting postures in conjunction with the accompanying drawings.

[0151] Figure 6a and Figure 6b The schematic diagrams of the structures of the terminal devices in the first placement state are respectively illustrated.

[0152] The terminal device 210 generally has a first placement state and a second placement state on the placement surface. Figure 6a As shown, when the terminal device 210 is in the first placement state, the long side 14 of the protective shell 1 is parallel to the placement surface.

[0153] refer to Figure 6a As shown, in some embodiments, when the terminal device 210 is in the first placement state, the second shell 2114 can be stacked on the side of the first shell 2111 away from the protective shell 1, so that the terminal device 210 is in a folded state. Alternatively, refer to Figure 6b As shown, in other embodiments, the second shell 2114 can also be rotated relative to the first shell 2111 toward the side of the protective shell 1 to a position parallel to the first shell 2111, so that the terminal device 210 is in a flat state.

[0154] refer to Figure 6a As shown, when the terminal device 210 is in the first placement state, the bracket 2 is supported on the housing 201 in a first supporting posture. When the bracket 2 is in the first supporting posture, the vertical projection of the connection end 221 on the wide side 15 is located in the middle of the wide side 15, so that the support plate 22 can be supported on the middle of the back of the protective shell 1 and the middle of the back of the first housing 2111. At this time, the support center of gravity and the center of gravity of the terminal device 210 are basically located on a straight line (not shown in the figure), which is perpendicular to the placement surface, thereby facilitating the bracket 2 in the first supporting posture to achieve stable support for the terminal device 210 in the folded state in the first placement state.

[0155] like Figure 6a As shown, the support plate 22 can be connected to one side of the top 214 of the connecting plate 21. In this way, while the bracket 2 is conducive to stably supporting the terminal device 210 in the first placement state in the first supporting posture, the connecting plate 21 can be used to Figure 6a The bracket 2 is rotated in the direction w indicated by the middle arrow relative to the mounting member 23 to a preset rotation angle to reach the second supporting posture, so as to ensure that when the bracket 2 is in the second supporting posture, the support plate 22 can be located on the side of the connecting plate 21 facing the second housing 2114. For example, the preset rotation angle may include but is not limited to 90 degrees.

[0156] refer to Figure 6bAs shown, when the terminal device 210 is in the first placement state, since the second shell 2114 is connected to the first shell 2111 and is located on the side of the first shell 2111 away from the placement surface, when the bracket 2 is in the first supporting posture and is supported by the support plate 22 on the middle part of the back side of the first shell 2111, it can also make the support center of gravity and the center of gravity of the terminal device 210 basically located on a straight line (not shown in the figure), which is perpendicular to the placement surface, thereby facilitating the bracket 2 to be in the first supporting posture and achieve stable support for the terminal device 210 in the first placement state in a flat state.

[0157] It should be noted that the first placement state can be the horizontal placement state of the terminal device 210. Therefore, the bracket 2 of the present application is conducive to achieving horizontal stable support for the terminal device 210 in the folded state and the flattened state in the first supporting posture.

[0158] Figure 6c and Figure 6d The schematic diagrams respectively illustrate the structures of the terminal device including the shell assembly in the second placement state.

[0159] refer to Figure 6c As shown, when the terminal device 210 is in the second placement state, the long side 14 of the protective shell 1 is set at an angle to the placement surface. Figure 6c As shown, in some embodiments, when the terminal device 210 is in the second placement state, the second shell 2114 can be positioned along Figure 6c The bracket 2 is rotated in the direction of the arrow in the middle and is stacked on the first shell 2111 to put the terminal device 210 in a folded state. The bracket 2 can be supported in the middle of the back of the protective shell 1 and the middle of the back of the first shell 2111 in a first supporting posture. At this time, the support center of gravity and the center of gravity of the terminal device 210 are basically located on a straight line (not shown in the figure), which is perpendicular to the placement surface, thereby facilitating the bracket 2 in the first supporting posture to achieve stable support for the terminal device 210 in the folded state in the second placement state.

[0160] refer to Figure 6d As shown, in some embodiments, when the terminal device assembly 200 is in the second placement state, the second housing 2114 can further rotate relative to the first housing 2111 toward the side of the protective shell 1 to a position parallel to the first housing 2111, so that the terminal device 210 is in a flattened state. At this time, the bracket 2 can be rotated by rotating the connecting plate 21 to put it in the second supporting posture, and the bracket 2 can be supported on the housing 201 of the terminal device 210 in the second supporting posture.

[0161] Figure 7 A second structural diagram of the shell assembly in the second supporting posture is shown.

[0162] Continue to refer Figure 6d and Figure 7 As shown, when the bracket 2 is in the second supporting posture, the length direction of the connecting plate 21 is perpendicular to the long side 14 of the protective shell 1, and the vertical projection of the connecting end 221 on the wide side 15 is located at the asymmetric center of the wide side 15, so that through the rotation of the connecting plate 21, the vertical projection of the connecting end 221 on the wide side 15 is located on the side of the wide side 15 toward the center of the shell 201, so that the supporting center of gravity Q1 of the bracket 2 moves toward the side of the center of gravity Q of the shell 201, so as to avoid the support center of gravity Q1 from seriously deviating from the center of gravity Q of the terminal device 210 when the bracket 2 is supported on the terminal device 210, which is beneficial for the bracket 2 to be in the second supporting posture and realize stable support of the terminal device 210 in the second placement state in the flattened state.

[0163] Among them, the second placement state can be understood as a vertical placement state. Therefore, the bracket 2 of the present application is conducive to achieving vertical and stable support for the terminal device 210 in the folded state in the first supporting posture, and the bracket 2 of the present application is conducive to achieving vertical and stable support for the terminal device 210 in the flattened state in the second supporting posture.

[0164] Continue to refer Figure 6d and Figure 7 As shown, when the terminal device 210 is in the second placement state, the bracket 2 is supported on the back of the protective shell 1 in the second supporting posture, and the vertical projection of the connection end 221 on the wide side 15 is located on the side of the wide side 15 facing the second shell 2114, so that the vertical projection of the connection end 221 on the wide side 15 is located on the side of the wide side 15 facing the center of the shell 201. At this time, the support portion 29 is supported on the side of the protective shell 1 facing the second shell 2114, so that the support center of gravity Q1 is closer to the center of the shell 201, which is conducive to achieving stable vertical support of the terminal device 210 by the bracket 2 in the flattened state.

[0165] It should be noted that Figure 6d and Figure 7 The support center of gravity and the center of gravity of the whole machine shown in the figure are only schematic structures and do not constitute a limitation on the positions of the support center of gravity and the center of gravity of the whole machine.

[0166] The present application can also adjust the length of the connecting plate 21 so that when the bracket 2 is in the second supporting posture, the vertical projection of the connecting end 221 on the wide side 15 is located on the side of the wide side 15 facing the second shell 2114.

[0167] refer to Figure 7 As shown, the length of the connecting plate 21 and the wide side 15 of the protective shell 1 satisfy the conditional formula: L+2L×sina=2S+C.

[0168] Where L is half the length of the connecting plate 21; a is the angle between the direction perpendicular to the plane of the connecting plate 21 and the length of the support plate 22 when the bracket 2 is in the second support posture; S is half the length of the wide side 15 of the protective shell 1; and C is the tolerance. C may include, but is not limited to, the dimensional tolerance of the connecting plate 21, the dimensional tolerance of the support plate 22, the dimensional tolerance of the protective shell 1, and the installation tolerance of the connecting plate 21 on the protective shell 1.

[0169] refer to Figure 7 Combined with Figure 6d As shown, this can ensure that the bracket 2 is in the second supporting posture, the supporting portion 29 can be supported on the side of the protective shell 1 facing the second shell 2114, and the vertical projection of the connecting end 221 on the wide side 15 is located on the side of the wide side 15 facing the second shell 2114, so that the support center of gravity Q1 is closer to the center of the shell 201, which is conducive to achieving vertical and stable support for the terminal device 210 in the second placement state, and can also make the length of the wide side 15 of the protective shell 1 greater than the length of the connecting plate 21, so as to avoid the end of the connecting plate 21 extending out of the protective shell 1, affecting the aesthetics of the shell assembly 100 and the terminal device assembly 200.

[0170] It should be noted that, in some embodiments, without considering the convenience of rotating the connecting plate 21 relative to the protective shell 1 , the protective shell 1 can also be rotated under the action of an external force to achieve the rotation of the connecting plate 21 relative to the mounting member 23 .

[0171] The structure of the housing assembly 100 of the present application will be further described below by taking the rotating connecting plate 21 as an example.

[0172] refer to Figure 6d and Figure 7 As shown, when the bracket 2 is in use, the support plate 22 can be rotated relative to the connecting plate 21 to form an angle with the connecting plate 21 and is relatively fixed. Because the plane on which the connecting plate 21 is located is parallel to the back of the protective case 1, when the bracket 2 is in use, the support plate 22 can form an angle with the back of the protective case 1, so that the terminal device 210 is supported on the placement surface by the support plate 22.

[0173] It should be noted that, when the bracket 2 is in use, the angle between the support plate 22 and the connecting plate 21 can refer to the relevant settings of the bracket 2 in the relevant technology, and is not further limited in this application.

[0174] The support plate 22 and the connecting plate 21 can adopt the conventional rotation connection method in the relevant technology. In the present application, the rotation connection method of the support plate 22 and the connecting plate 21 is not further limited. Exemplarily, the support plate 22 can be connected to the connecting plate 21 through a rotating shaft (not shown in the figure). Among them, a torsion spring (not shown in the figure) can be provided on the rotating shaft, and the torsion spring can abut between the support plate 22 and the connecting plate 21, so that when the support plate 22 rotates relative to the connecting plate 21 to form an angle with the protective shell 1, under the action of the torsion spring, the support plate 22 can be fixed relative to the connecting plate 21, and the support plate 22 and the connecting plate 21 are maintained at a certain angle, so that the bracket 2 is in use.

[0175] Figure 8 The figure shows a structural diagram of a housing assembly in a non-use state.

[0176] refer to Figure 8 As shown, the support plate 22 can be rotated relative to the connecting plate and covered on the connecting plate 21, so that when the terminal device does not need to be supported by the bracket, the support plate 22 can be rotated to cover and block the connecting plate 21 through the support plate 22, so that the bracket 2 and the shell assembly 100 are in a non-use state. While increasing the portability and aesthetics of the terminal device assembly 200, it can also avoid damage to the bracket 2 under the action of external force.

[0177] When the support plate 22 is covered on the connecting plate 21, the support plate 22 can also be magnetically attracted to the connecting plate 21. When the bracket is needed, when the support plate 22 is rotated away from the connecting plate 21, the torsion spring can bounce the support plate 22 away from the connecting plate 21 and maintain a certain angle between the support plate 22 and the connecting plate 21, so that the bracket 2 is in use and the terminal device can be supported by the bracket 2.

[0178] Figure 9 A schematic diagram of the structure of a bracket is shown.

[0179] refer to Figure 9 As shown, the end face of the connecting end 221 is an inclined surface 222 inclined toward one side of the center of the support plate 22, so that the setting of the inclined surface 222 can not only prevent the support plate 22 from rotating on the connecting plate 21 and scratching the protective shell 1 during the process of opening the bracket 2 to the use state, but also prevent the protective shell 1 from interfering with the rotation of the support plate 22.

[0180] It should be noted that, in actual use, the inclination angle of the inclined surface 222 can be adjusted based on the rotation angle of the support plate 22 relative to the connecting plate 21 when the bracket 2 is in use, as well as the assembly gap between the support plate 22 and the protective shell 1, to ensure that the support plate 22 does not scratch the protective shell 1 during rotation and to prevent the protective shell 1 from interfering with the rotation of the support plate 22. In this application, the inclination angle of the inclined surface 222 is not further limited.

[0181] Figure 10 A schematic structural diagram of the first bracket is shown.

[0182] refer to Figure 10 As shown, the connecting plate 21 has an assembly groove 215 on a side facing the mounting member 23. The assembly groove 215 is located in the middle of the connecting plate 21. The mounting member 23 is located in the assembly groove 215. When the mounting member 23 is assembled in the connecting plate 21, the thickness of the connecting plate 21 can be used to conceal the thickness of the mounting member 23, thereby facilitating the lightweight and thinning of the bracket 2, the housing assembly 100, and the terminal device assembly 200.

[0183] Continue to refer Figure 10 As shown, in some embodiments, the side of the connecting plate 21 facing the protective shell 1 has at least one friction plate 25, and the friction plate 25 is located on the side of the mounting member 23 to prevent the connecting plate 21 from scratching the protective shell 1 in the thickness direction during the rotation relative to the mounting member 23. The thickness direction of the protective shell 1 can be referred to Figure 4 The Z direction in .

[0184] Specifically, the friction plate 25 can be located on the side of the assembly groove 215 so as not to affect the assembly of the mounting member 23 in the assembly groove 215, while preventing the connecting plate 21 from scratching the protective shell 1 in the thickness direction during the rotation relative to the protective shell 1.

[0185] For example, the number of friction plates 25 in the bracket 2 may include but is not limited to one or two. Taking two friction plates 25 as an example, Figure 10 As shown, since the assembly groove 215 is located in the middle of the connecting plate 21 , the two friction plates 25 can be respectively disposed at the two ends of the connecting plate 21 .

[0186] Continue to refer Figure 10As shown, the mounting member 23 is a disc-shaped structure, with a stopper 233 provided circumferentially therearound. The connecting plate 21 is provided with a limiter assembly comprising two limiter protrusions 212 extending from the connecting plate 21 toward one side of the mounting member 23. The stopper 233 is located between the two limiter protrusions 212 to block the limiter protrusions 212 and limit the position of the connecting plate 21 relative to the mounting member and the protective shell 1. Furthermore, the stopper 233 and the two limiter protrusions 212 increase the reverse force of the connecting plate 21, limiting the rotation angle of the connecting plate 21 relative to the mounting member 23 and the protective shell 1, thereby preventing the connecting plate 21 from excessively rotating relative to the mounting member 23.

[0187] Continue to refer Figure 10 As shown, the blocking block 233 is located on the rotation path of the limiting protrusion 212, and the two facing surfaces of the two limiting protrusions 212 are set at an angle, and the angle b formed by the two surfaces is the same as the preset rotation angle of the connecting plate 21 relative to the mounting member 23, so that the blocking portion and the two limiting protrusions 212 can cooperate to limit the connecting plate 21 in the first supporting posture and the second supporting posture to avoid excessive rotation of the connecting plate 21 relative to the mounting member 23.

[0188] The number of the blocking blocks 233 is equal to the number of the limiting groups. One blocking block 233 and one limiting group can form a limiting unit of the bracket 2. Figure 10 As shown, the bracket 2 has a limiting unit.

[0189] Figures 11a to 11c The partial structural diagrams of the second support in the first support posture, the intermediate state and the second support posture are shown respectively. Figures 11a to 11c The diagram illustrates only the relative positional relationship between the limiting protrusion 212 and the blocking block 233 during the rotation of the connecting plate 21 relative to the mounting member 23, to facilitate understanding of the limiting effect of the blocking block 233 on the limiting protrusion 212. It should be understood that during the rotation of the connecting plate 21 relative to the mounting member 23 and the protective housing 1, the relative positions of the mounting member 23 and the protective housing 1 remain fixed.

[0190] refer to Figures 11a to 11c It can be seen that there are two limiting units on the bracket 2. Alternatively, in some embodiments, there may be more than two limiting units on the bracket 2. Taking two limiting units as an example, continue to refer to Figures 11a to 11c The two blocking blocks 233 in the two limiting units can be symmetrically arranged in the circumferential direction of the mounting member 23, and the two limiting groups in the two limiting units can be symmetrically arranged on the connecting plate 21, so as to achieve a better limiting effect on the connecting plate 21 through the two limiting units.

[0191] refer to Figure 11aAs shown, the rotatable angle of the connecting plate 21 on the mounting member 23 can be greater than or equal to 0° and less than or equal to 90°. When the connecting plate 21 is in the first supporting posture, the blocking block 233 blocks a limiting protrusion 212 in the limiting group. Figures 11a to 11c As shown, the connecting plate 21 is along Figure 11a The direction of the arrow in the figure is rotated 90 degrees (the preset rotation angle is 90 degrees), and another limiting protrusion 212 in the limiting group is blocked by the blocking block 233. At this time, the connecting plate 21 reaches Figure 11c The second support posture is shown in FIG.

[0192] When the connecting plate 21 reaches the second supporting posture, it can also move along the Figure 11a The vehicle continues to rotate 90° in the direction opposite to the middle arrow, is blocked by the blocking block 233, and returns to the first supporting posture.

[0193] It should be noted that as the rotatable angle of the connecting plate 21 on the protective shell 1 changes, the angle between the two limiting protrusions 212 in the limiting group also changes. In this application, no further limitation is made on the preset rotation angle when the connecting plate 21 rotates from the first supporting posture to the second supporting posture.

[0194] Continue to refer Figures 11a to 11c , the blocking block 233 may be a square block. In some embodiments, the blocking block 233 may also be a circular block or a block structure of other shapes. In the present application, the structure of the blocking block 233 is not further limited. The limiting protrusion 212 may be a protrusion extending toward one side of the mounting member 23 on the groove wall of the assembly groove 215. In the present application, the structure of the limiting protrusion 212 is not further limited, as long as it is ensured that the blocking block 233 can stably block the limiting protrusion 212, and that the mounting member 23 can make the connecting plate 21 basically in a vertical state or a horizontal state on the protective shell 1 after cooperating with the bracket 2 on the protective shell 1.

[0195] It should be noted that when the connecting plate 21 is in a vertical state on the protective shell 1, the bracket 2 is in a first supporting posture, and when the connecting plate 21 is in a horizontal state on the protective shell 1, the bracket 2 is in a second supporting posture.

[0196] Figure 12 Indicated Figure 8 The partial cross-sectional view of the housing assembly in the AA direction is provided to facilitate understanding of the assembly of the connecting plate 21 on the mounting member 23 and the protective shell 1. Figure 12 The support plate 22 of the bracket 2 is hidden in the figure to simplify the structural view of the housing assembly 100.

[0197] refer to Figure 12As shown, the mounting member 23 has a revolving surface (not shown), the central axis o1 of which is perpendicular to the back of the protective case 1. The central portion of the connecting plate 21 is rotatably connected to the mounting member 23 via the revolving surface, so that the central portion of the connecting plate 21 is rotatably mounted on the mounting member 23 and can rotate relative to the mounting member 23 about the central axis o1 of the revolving surface, thereby enabling the bracket 2 to have a first supporting posture and a second supporting posture, thereby facilitating stable support of the terminal device 210 in the first and second placement positions.

[0198] Continue to refer Figure 4 As shown, in some embodiments, the mounting member 23 may be a disc-shaped structure having a revolving surface. In other embodiments, the mounting member 23 may also have other structures having a revolving surface, provided that the rotation of the connecting plate 21 relative to the protective housing 1 is not affected. For example, the mounting member 23 may also have a square structure having a revolving surface. In this application, the structure of the mounting member 23 is not further limited.

[0199] The structure of the housing assembly 100 of the present application is further described below by taking the mounting member 23 as a disc-shaped structure with a revolving surface as an example.

[0200] refer to Figure 12 As shown, the mounting member 23 has a rotation groove 231, and the groove wall of the rotation groove 231 forms a rotation surface. The groove wall of the rotation groove 231 can be understood as a closed surface formed by rotating one side of the rotation groove around the rotation axis, and this closed surface can serve as the rotation surface. The middle part of the connecting plate 21 has a rotation portion 211 extending into the rotation groove 231. The outer wall of the rotation portion 211 is in rotational contact with the rotation surface, so that the middle part of the connecting plate 21 is rotated and set on the mounting member 23 through the rotational contact between the rotation portion 211 and the rotation surface. In this way, the middle part of the connecting plate 21 can rotate to different directions around the central axis o1 of the rotation surface relative to the mounting member 23 and the protective shell 1 to change the supporting posture of the bracket 2 on the protective shell 1, so that the support plate 22 can be supported at different positions on the protective shell 1 in the first supporting posture and the second supporting posture, thereby achieving stable support of the terminal device 210 by the bracket 2 in the first placement state and the second placement state.

[0201] Moreover, by setting the rotation groove 231, the rotation of the connecting plate 21 in the back direction of the protective shell 1 can be limited, so that the middle part of the connecting plate 21 can rotate around the central axis o1 of the rotation surface in the middle of the back of the protective shell 1, so as to ensure that when the bracket 2 is in the second supporting posture, the supporting center of gravity is closer to the center of the shell 201 in the second placement state.

[0202] Continue to refer Figure 12As shown, in some embodiments, the mounting member 23 can be connected to the back of the protective shell 1 by means of hot melt, adhesive bonding, etc., so as to achieve a fixed connection of the mounting member 23 to the middle portion of the back of the protective shell 1. Specifically, the mounting member 23 can be provided with an assembly portion 232 on the side facing the protective shell 1, and the protective shell 1 can be provided with an assembly hole 12 at a position opposite to the assembly portion 232. When the mounting member 23 is fixedly connected to the protective shell 1 by means of hot melt, adhesive bonding, etc., the assembly portion 232 can be assembled in the assembly hole 12, so that the assembly position of the mounting member 23 on the protective shell 1 is positioned by the cooperation between the assembly portion 232 and the assembly hole 12.

[0203] It should be noted that when the mounting member 23 is bonded to the protective shell 1, the bonding of the mounting member 23 and the protective shell 1 can be achieved at any position of the mounting member 23 to ensure that when the bracket 2 is in the first supporting posture, the vertical projection of the connecting end 221 on the wide side 15 of the protective shell 1 is located in the middle of the wide side 15.

[0204] Figure 13 A schematic diagram of the structure of another protective shell is shown. Figure 14 The connecting plate is shown in Figure 13 Assembly diagram in the protective shell. Figure 13 Part of the structure on the protective shell 1 is hidden in order to simplify the structural view of the protective shell 1.

[0205] refer to Figure 13 and Figure 14 As shown, in other embodiments, the mounting member 23 can also be an integral structure with the protective shell 1. Specifically, in this application, the mounting member 23 can be formed into an integral structure with the protective shell 1 through other existing processes such as insert injection molding, two-color injection molding of different materials, etc., so as to reduce the assembly tolerance of the mounting member 23 on the protective shell 1.

[0206] like Figure 12 As shown, in some embodiments, the shell assembly 100 may further include a fixing member 24, which is connected to the connecting plate 21, and the fixing member 24 is relatively fixed to the protective shell 1 in the central axis direction of the rotating surface, which is conducive to the assembly of the connecting plate 21 on the protective shell 1.

[0207] Continue to refer Figure 12As shown, in some embodiments, the protective shell 1 has a accommodating cavity 11, and the accommodating cavity 11 has a mounting hole 111 on the side facing the connecting plate 21, and the aperture of the mounting hole 111 is smaller than the inner diameter of the accommodating cavity 11. The fixing member 24 is arranged in the accommodating cavity 11 to realize the assembly of the fixing member 24 in the protective shell 1. The rotating portion 211 extends into the mounting hole 111 and is connected to the fixing member 24. Since the fixing member 24 is relatively fixed to the protective shell 1 in the central axial direction of the rotating surface, when the rotating portion 211 extends into the mounting hole 111 and is connected to the fixing member 24, the connecting plate 21 can be assembled on the protective shell 1 through the fixing member 24, and the connection plate 21 can be limited in the central axial direction of the rotating surface to prevent the connecting plate 21 from detaching from the protective shell 1 during rotation.

[0208] Continue to refer Figure 12 As shown, the fixing member 24 may be an annular member, and the rotating portion 211 passes through the center hole of the fixing member 24 and is riveted to the fixing member 24. Since the rotating portion 211 is in rotational contact with the rotating surface of the mounting member 23 and is riveted to the fixing member 24, the fixing member 24 stabilizes the connecting plate 21 on the protective shell 1. When the fixing member 24 rotates with the connecting plate 21 relative to the mounting member 23 and the protective shell 1, it does not affect the rotation of the middle portion of the connecting plate 21 disposed on the mounting member 23, thereby ensuring that the middle portion of the connecting plate 21 can rotate relative to the mounting member 23.

[0209] Continue to refer Figure 12 As shown, in order to achieve the fixation of the fixing member 24 in the accommodating cavity 11, the fixing member 24 may further include a mounting portion 241 and an overlapping portion 242. The mounting portion 241 is an annular structure. Part of the structure of the mounting portion 241 extends into the mounting hole 111. The center hole of the fixing member 24 is arranged in the mounting portion 241. The rotating portion 211 is passed through the center hole of the fixing member 24 and is riveted to the mounting portion 241. The overlapping portion 242 is located on the circumferential side wall of the mounting portion 241, is located in the accommodating cavity 11, and overlaps the protective shell 1 to achieve the fixation of the fixing member 24 in the accommodating cavity 11. The overlapping portion 242 may be an annular structure. Alternatively, the overlapping portion 242 may also include a plurality of block structures, which are adapted to the circumferential side wall of the mounting portion 241 and are evenly distributed around the circumference of the fixing member 24 to enhance the stability of the assembly of the fixing member 24 in the accommodating cavity 11.

[0210] like Figure 12 As shown, in order to facilitate the rotating part 211 to extend into the mounting hole 111, the rotating groove 231 can be a rotating hole, so that the rotating part 211 can pass through the rotating groove 231 and rotate in contact with the rotating surface, and can also be passed through the center hole of the fixing part 24 to achieve riveting of the rotating part 211 and the fixing part 24.

[0211] Alternatively, in some embodiments, while ensuring that the rotating portion 211 is in rotational contact with the rotating surface and does not affect the rotational arrangement of the connecting plate 21 on the protective shell 1, the connecting plate 21 can also be assembled on the protective shell 1 through other methods. For example, the connecting plate 21 can also be directly connected to the circumferential rotation of the mounting member 23 by engaging a connecting block with a circumferential sliding groove of the mounting member 23. In this case, the rotation groove 231 can also be a recessed structure on the mounting member 23. In this application, the assembly method of the connecting plate 21 on the protective shell 1 is not further limited.

[0212] The structure of the housing assembly 100 of the present application will be further described below using the rotary hole as an example.

[0213] Figure 15 A schematic diagram illustrating the concave-convex fit between a mounting member and a connecting plate is shown.

[0214] Continue to refer Figure 15 Combined with Figure 12 As shown, in some embodiments, the shell assembly 100 also includes a damping unit 26, which abuts between the mounting member 23 and the connecting plate 21 to provide rotational damping of the connecting plate 21 relative to the mounting member 23, so that the bracket 2 can achieve stable support for the terminal device 210 in both the first supporting posture and the second supporting posture.

[0215] Continue to refer Figure 15 Combined with Figure 12 As shown, the damping unit 26 may include at least one of a gasket 261 and an elastic group (not shown in the figure). Figure 15 As shown, the elastic group may include an elastic member 262, which abuts against the circumferential side wall of the mounting member 23 and is connected to the connecting plate 21. When the connecting plate 21 rotates, the friction generated by the relative movement between the elastic member 262 and the mounting member 23 provides a portion of the rotational damping of the bracket 2. The elastic group may be disposed within the mounting groove 215 of the connecting plate 21 and located on the side of the circumferential groove wall of the mounting member 23 that faces the mounting groove 215.

[0216] like Figure 12 As shown, the washer 261 can be located on the side of the mounting member 23 facing the connecting plate 21 and sandwiched between the mounting member 23 and the connecting plate 21. In this way, when the connecting plate 21 rotates, friction is generated between the washer 261 and the mounting member 23 and the connecting plate 21. The friction generated between the washer 261 and the mounting member 23 and the connecting plate 21 can provide another part of the rotation damping of the bracket 2.

[0217] Therefore, the rotational damping of the bracket 2 can be provided by the friction between the elastic member 262 and the mounting member 23, and the friction between the gasket 261, the mounting member 23, and the connecting plate 21. The sum of the rotational damping provided by the gasket 261 and the elastic member 262 can overcome the torsional force caused by the gravity of the terminal device 210, thereby ensuring that the bracket 2 can stably support the terminal device 210 in different placement states in both the first support posture and the second support posture.

[0218] like Figure 12 As shown, the gasket 261 can be an annular gasket, and the rotating portion 211 passes through the center hole of the gasket 261 and is in rotational contact with the rotating surface, so that while the gasket 261 provides a part of the rotation damping for the bracket 2, it can also facilitate the middle part of the connecting plate 21 to be rotated and set on the mounting member 23 through the rotating surface, thereby avoiding the setting of the gasket 261 affecting the rotation setting of the connecting plate 21 relative to the protective shell 1.

[0219] like Figure 12 As shown, the gasket 261 can be arranged in the assembly groove 215 of the connecting plate 21, and the side of the mounting member 23 facing the connecting plate 21 can be provided with an annular avoidance groove (not shown in the figure), and part of the structure of the gasket 261 can be assembled in the avoidance groove, so that the gasket 261 can be pressed between the mounting member 23 and the connecting plate 21, while also reducing the thickness of the shell assembly 100 and the terminal equipment assembly 200.

[0220] Continue to refer Figure 15 As shown, the damping unit 26 may include at least two elastic groups, and the at least two elastic groups are evenly distributed around the circumference of the mounting member 23, so that the elastic members 262 in the at least two elastic groups abut against the circumferential side walls of the mounting member 23 in different directions, thereby providing rotational damping for the connecting plate 21 and making the rotation of the connecting plate 21 relative to the mounting member 23 more stable.

[0221] Continue to refer Figure 15 As shown, in some embodiments, the elastic member 262 may include a first elastic member 2621, which is connected to the connecting plate 21 and abuts against the circumferential side wall of the mounting member 23. In this way, when the connecting plate 21 rotates, the first elastic member 2621 rotates synchronously with the connecting plate 21 relative to the mounting member 23. The friction force generated by the relative movement between the first elastic member 2621 and the mounting member 23 can provide rotational damping for the connecting plate 21.

[0222] from Figure 15As can be seen in the figure, the first elastic member 2621 includes a fixing section 2622 and an abutting section 2623. The abutting section 2623 matches the shape of the circumferential side wall of the mounting member 23 and abuts against the circumferential side wall of the mounting member 23. The fixing section 2622 is connected to the end of the abutting section 2623 and is connected to the connecting plate 21. The first elastic member 2621 may include, but is not limited to, a spring. In this way, while the fixing section 2622 enables the first elastic member 2621 to be connected to the connecting plate 21, the abutting section 2623 can also abut against the circumferential side wall of the mounting member 23, thereby achieving abutment of the first elastic member 2621 against the circumferential side wall of the mounting member 23.

[0223] When the mounting member 23 is a disc-shaped structure with a revolving surface, the abutting section 2623 may be an arcuate section adapted to the shape of the circumferential sidewall of the mounting member 23, so that the first elastic member 2621 can rotate relative to the mounting member 23 along with the connecting plate 21. The first elastic member 2621 can be connected to the connecting plate 21 by dispensing glue, clamping, or other methods to achieve the connection of the first elastic member 2621 to the connecting plate 21.

[0224] like Figure 15 As shown, in some embodiments, the first elastic member 2621 can be clamped between the mounting member 23 and the connecting plate 21, so that the first elastic member 2621 can be assembled on the connecting plate 21 while being able to abut against the circumferential side wall of the mounting member 23. Specifically, the first elastic member 2621 can be assembled in the assembly groove 215 of the connecting plate 21 and clamped between the groove wall of the assembly groove 215 and the mounting member 23.

[0225] refer to Figure 15 As shown, in some embodiments, the mounting member 23 may further include a snap-fit ​​portion 234, and the connecting plate 21 may further include a snap-fit ​​portion (not shown in the figure). The snap-fit ​​portion and the snap-fit ​​portion 234 are arranged relative to each other. When the bracket 2 is in the first supporting posture and the second supporting posture, the snap-fit ​​portion 234 is snap-fitted with the snap-fit ​​portion, so that the snap-fit ​​portion 234 is snap-fitted with the snap-fit ​​portion, so that when the connecting plate 21 is rotated to the specified position (such as the first supporting posture or the second supporting posture), a certain sense of frustration will be generated, thereby prompting that the bracket 2 has been rotated into place.

[0226] Continue to refer Figure 15 As shown, in some embodiments, the engaging portion 234 can be located on a surface of the mounting member 23 facing the connecting plate 21. Accordingly, the engaging portion can be located in the assembly groove 215 of the connecting plate 21 at a position opposite to the engaging portion 234, so as to achieve engagement between the engaging portion 234 and the engaging portion.

[0227] Figure 16 A schematic diagram illustrating another concave-convex fit between a mounting member and a connecting plate is shown.

[0228] refer to Figure 16 As shown, in other embodiments, the engaging portion 234 may be located on the side of the blocking block 233 facing the limiting protrusion 212. Accordingly, the engaging portion 213 may be located on the limiting protrusion 212 of the connecting plate 21 at a position opposite the engaging portion 234, so as to achieve engagement between the engaging portion 234 and the engaging portion 213. This allows for greater diversity in the placement of the engaging portion 234 and the engaging portion 213 while ensuring engagement between the engaging portion 234 and the engaging portion 213.

[0229] refer to Figure 16 As shown, the engaging portion 234 may be a convex structure, and the engaging portion 213 may include but is not limited to a concave structure adapted to the convex structure. Alternatively, in some embodiments, the engaging portion 234 may be a concave structure, and the engaging portion 213 may include but is not limited to a convex structure adapted to the concave structure.

[0230] In the present application, there is no specific limitation on the positions of the snap-fitting portion 234 and the snap-fitting portion 213. As long as the limiting protrusion 212 and the blocking block 233 are in contact, the snap-fitting portion 213 is set at any position where the connecting plate 21 and the mounting member 23 cooperate, and the snap-fitting portion 234 is set at a position on the mounting member 23 opposite to the snap-fitting portion 234 to ensure that the snap-fitting portion 213 and the snap-fitting portion 234 appear in pairs.

[0231] It should be noted that after determining the position of the clamping portion 213 and the engaging portion 234, a pair of clamping portions 213 and engaging portions 234 are provided, or only one of the clamping portion 213 and engaging portion 234 is provided, with the rotation axis of the rotation surface as the midpoint, along the rotation direction of the connecting plate 21, at intervals corresponding to a preset rotation angle of the connecting plate 21 (e.g., 90°). This ensures that a certain degree of jerkiness is not generated when the connecting plate 21 rotates to the first supporting posture or the second supporting posture.

[0232] Figure 17 and Figure 18 Schematic diagrams of assembling a first elastic member on a mounting member from different viewing angles are shown respectively.

[0233] refer to Figure 17As shown, in some embodiments, a step 235 may be further provided on the side of the mounting member 23 facing the connecting plate 21 in the circumferential direction. The step 235 includes a step surface 2351 and a step side wall 2352 provided at an angle to the step surface 2351. The abutting section 2623 is located on the step surface 2351 and abuts against the step side wall 2352. The step side wall 2352 forms the circumferential side wall of the mounting member 23. In this way, while ensuring that the abutting section 2623 abuts against the circumferential side wall of the mounting member 23, when the connecting plate 21 is assembled on the protective shell 1 through the fixing member 24, the connecting plate 21 can be Figure 18 As shown in the figure, the first elastic member 2621 is pressed onto the abutting section 2623 to prevent the first elastic member 2621 from falling off from the bracket 2 during use.

[0234] In order not to affect the rotation of the connecting plate 21 relative to the protective shell 1, refer to Figure 17 As shown, in some embodiments, a circle of steps 235 can be provided on the circumference of the mounting member 23 to match the rotation of the bracket 2 having two limiting units on the protective shell 1. It should be understood that as the number of limiting units on the bracket 2 changes, the proportion of the steps 235 on the circumference of the mounting member 23 also changes. For example, when the bracket 2 has one limiting unit, the central angle corresponding to the arc length of the step 235 on the circumference of the mounting member 23 should be greater than or equal to the preset rotation angle (e.g., 90°) when the connecting plate 21 rotates from the first supporting posture to the second supporting posture.

[0235] Figure 19 Another schematic diagram of assembling the first elastic member on the mounting member is shown.

[0236] refer to Figure 19 As shown, in some embodiments, the mounting member 23 may have a snap-fit ​​portion 234, and the abutting section 2623 may have a snap-fit ​​portion 213, with the snap-fit ​​portion 213 being disposed opposite the snap-fit ​​portion 234. When the bracket 2 is in the first supporting posture and the second supporting posture, the snap-fit ​​portion 234 snaps into engagement with the snap-fit ​​portion 213, so that when the connecting plate 21 rotates to a specified position (e.g., the first supporting posture or the second supporting posture), a certain sense of frustration is generated, thereby indicating that the bracket 2 has been rotated to the designated position.

[0237] continue Figure 19 As shown, the engaging portion 213 may be a protruding structure on the abutting section 2623, and the engaging portion 234 may be a recessed structure on the circumference of the mounting member 23 that matches the protruding structure, so as to achieve the engaging between the engaging portion 213 and the abutting section 2623. Alternatively, in some embodiments, the engaging portion 213 may be a recessed structure on the abutting section 2623, and the engaging portion 234 may be a protruding structure on the circumference of the mounting member 23 that matches the recessed structure, which can also achieve the engaging between the engaging portion 213 and the abutting section 2623.

[0238] It should be noted that, in the present application, the arrangement positions of the engaging portion 234 on the mounting member 23 and the engaging portion 213 on the abutting section 2623 are not further elaborated. For details, please refer to the relevant description above.

[0239] Figure 20 and Figure 21 The partial assembly diagrams of the second elastic member and the adjusting member on the connecting plate and the mounting member are shown respectively, so as to facilitate the understanding of the assembly of the second elastic member 2624 on the connecting plate 21 and the mounting member 23. Figure 20 The structure of the protective shell 1 is hidden in the figure, so that the assembly of the second elastic member 2624 and the adjusting member 27 on the connecting plate 21 and the mounting member 23 can be observed.

[0240] refer to Figure 20 and Figure 21 As shown, in some embodiments, the elastic member (not shown in the figure) may include a second elastic member 2624, and the elastic group may further include an abutment block 2625 that matches the shape of the circumferential side wall of the mounting member 23. The abutment block 2625 abuts the circumferential side wall of the mounting member 23, and the second elastic member 2624 abuts between the abutment block 2625 and the connecting plate 21. In this way, the second elastic member 2624 can exert a certain elastic force on the abutment block 2625, causing the abutment block 2625 to abut the circumferential side wall of the mounting member 23, thereby achieving indirect abutment between the second elastic member 2624 and the circumferential side wall of the mounting member 23. When the connecting plate 21 rotates, since the second elastic member 2624 is connected to the connecting plate 21, the second elastic member 2624 and the abutment block 2625 will rotate with the connecting plate 21. The friction generated by the relative motion between the abutment block 2625 and the mounting member 23 can provide a portion of the rotational damping required for the connecting plate 21 to rotate.

[0241] The abutment block 2625 may be an arc-shaped block that matches the shape of the circumferential sidewall of the mounting member 23. The arc-shaped block may have a certain friction coefficient so that friction can be generated when the abutment block 2625 and the mounting member 23 move relative to each other. The second elastic member 2624 may be a spring. Alternatively, in some embodiments, the second elastic member 2624 may be another elastic structure capable of generating elastic force, for example, the second elastic member 2624 may be silicone.

[0242] To avoid the position deviation of the second elastic member 2624, refer to Figure 20 and Figure 21As shown, in some embodiments, the elastic group may further include a limiting cylinder 2626, which is located on the side of the groove wall of the mounting member 23 facing the assembly groove 215 in the circumferential direction, and the second elastic member 2624 is passed through the limiting cylinder 2626, so as not to affect the connection between the second elastic member 2624 and the abutment block 2625 and the connecting plate 21, and at the same time, the position of the second elastic member 2624 relative to the abutment block 2625 can be limited to ensure that the second elastic member 2624 can stably abut the abutment block 2625 against the circumferential side wall of the mounting member 23.

[0243] Alternatively, in some embodiments, the elastic group may further include a limiting post (not shown in the figure), which may replace the limiting cylinder 2626 and pass through the second elastic member 2624 (such as a spring), and can also limit the position of the second elastic member 2624 relative to the abutment block 2625. In this application, the structure of the elastic group is not further defined.

[0244] Continue to refer Figure 21 As shown, in some embodiments, the rotating portion 211 may be threadedly connected to the fixing member 24. In this case, the bracket 2 may further include an adjusting member 27, which may include a fixing end 271. The fixing end 271 may be assembled on the fixing member 24 and located in the accommodating cavity 11 of the protective shell 1 to achieve assembly of the adjusting member 27 in the protective shell 1.

[0245] Continue to refer Figure 21 As shown, the adjusting member 27 may further include a screw-on portion 272 connected to the fixed end 271. The screw-on portion 272 is assembled in the center hole (not shown in the figure) of the fixing member 24, and is inserted into the rotating portion 211 of the connecting plate 21 and is threadedly connected to the rotating portion 211. In this way, without affecting the assembly effect of the connecting plate 21 on the protective shell 1, the assembly gap between the connecting plate 21 and the protective shell 1 can be adjusted by adjusting the effective connection length of the rotating portion 211 and the screw-on portion 272, thereby adjusting the degree of pressure of the gasket (not shown in the figure) between the connecting plate 21 and the mounting member 23, thereby adjusting the rotational damping of the connecting plate 21.

[0246] For example, the adjusting member 27 may include but is not limited to a bolt, a screw or a screw-on structure with a thread. Taking a bolt as an example, the fixing end 271 may be a nut of the bolt, and the screw-on portion 272 may be a threaded section of the bolt.

[0247] Continue to refer Figure 21As shown, when the rotational damping of the connecting plate 21 is adjusted to the desired requirement through the adjusting member 27, the adjusting member 27 can also be bonded to the fixing member 24 and the rotating portion 211 through a preset hot melt adhesive to avoid affecting the threaded connection effect between the adjusting member 27 and the rotating portion 211 when the connecting plate 21 rotates relative to the protective shell 1, while also enabling the adjusting member 27 to rotate synchronously with the connecting plate 21.

[0248] Due to the arrangement of the protective shell 1 and the bracket 2 in the shell assembly 100 of the present application, the protective shell 1 is covered on the back of the terminal device, and the bracket 2 is installed in the middle of the back of the protective shell 1 through the mounting member 23, so that the bracket 2 can be assembled on the back of the shell 201 through the protective shell 1, meeting the aesthetic requirements of the bracket 2 on the protective shell 1.

[0249] When the terminal device 210 is in the above-mentioned first placement state and is supported on the placement surface by the end of the support plate 22 away from the connecting plate 21, or when the terminal device 210 is in the above-mentioned second placement state and is supported on the placement surface by the end of the support plate 22 away from the connecting plate 21, the support plate 22 can be supported on the back of the protective shell 1, which is conducive to achieving stable support for the terminal device 210.

[0250] Furthermore, when the terminal device 210 is a folding device, when the terminal device 210 is in a flattened state and in the above-mentioned second placement state, and is supported on the placement surface by one end of the support plate 22 away from the connecting plate 21, the connecting plate 21 can also be rotated relative to the mounting member 23 and the protective shell 1, so that the support plate 22 can be supported on the position of the center of gravity of the protective shell 1 toward the terminal device 210 before and after the rotation of the connecting plate 21, so as to adjust the support center of gravity of the bracket 2 relative to the center of gravity of the terminal device assembly 200, thereby achieving stable support for the flattened state of the terminal device 210 in the second placement state.

[0251] Therefore, when the rotation damping required for the rotation of the bracket 2 is provided by the damping unit 26, the housing assembly 100 of the present application can achieve stable support of the bracket 2 for the terminal device 210 in different placement states.

[0252] It should be noted that the housing assembly 100 of the present application can also be used to support large-sized terminal products such as laptop computers and tablet computers in the second placement state (vertical placement state) whose center of gravity is eccentric with the center of gravity of the entire device. In this application, the application scenarios of the housing assembly 100 and the type of terminal device 210 are not further limited.

[0253] Based on the above, an embodiment of the present application further provides a terminal device assembly 200. As described above, the terminal device assembly 200 includes a terminal device 210. The terminal device assembly 200 may also include the above-mentioned housing assembly 100. The terminal device 210 may include a housing 201. The protective shell 1 of the housing assembly 100 is used to cover at least a portion of the structure of the housing 201, so that the bracket 2 can provide stable support for the terminal device 210 in different placement states.

[0254] It should be noted that the structure of the terminal device 210 can refer to the relevant description above and is not further limited here.

[0255] When the terminal device 210 is a foldable device (such as a foldable mobile phone), the protective case 1 can be placed on part of the housing 201 of the terminal device 210, for example, the protective case 1 can be placed on the back cover 2113. When the terminal device 210 is other non-foldable terminal products such as a tablet computer, the protective case 1 can be placed on the entire housing 201 of the terminal device 210.

[0256] The structure of the terminal device component 200 of the present application is further explained below by taking a folding device as an example.

[0257] like Figures 6a to 6d As shown in , as described above, when the support plate 22 forms an angle with respect to the back surface of the protective shell 1, the support plate 22 is supported on the back surface of the protective shell 1 via the connecting end 221. The connecting plate 21 rotates relative to the mounting member 23 to enable the bracket 2 to be in a first supporting posture and a second supporting posture. The terminal device 210 has a first placement state and a second placement state. When the terminal device 210 is in the first placement state, the long side 14 of the protective shell 1 is parallel to the placement surface, and the bracket 2 is supported on the back surface of the protective shell 1 in the first supporting posture to achieve stable support for the terminal device 210 in the first placement state.

[0258] When the terminal device 210 is in the second placement state, the second shell 2114 and the first shell are located in the same plane, the long side 14 is set at an angle to the placement surface, and the bracket 2 is supported on the back of the protective shell 1 in a first supporting posture or a second supporting posture, so that in the second placement state, as the structure of the terminal device 210 changes, the supporting posture of the bracket 2 is adjusted, so that the bracket 2 can achieve stable support for the terminal device 210 in the second placement state in the folded state and the flattened state.

[0259] As described above, if Figure 6a and Figure 6bAs shown, in some embodiments, the housing 201 may include a first housing 2111 and a second housing 2114, the first housing 2111 and the second housing 2114 being rotatably connected, and a protective shell 1 covering the back of the first housing 2111, with the back of the protective shell 1 being parallel to the back of the first housing 2111, and the first length direction being parallel to the length direction of the first housing 2111. The structures of the first housing 2111 and the second housing 2114 can be referred to the relevant description above and will not be further described here. The protective shell 1 can be set on the battery cover 2113 in the first housing 2111.

[0260] like Figure 6a and Figure 6b As shown, when the terminal device 210 is in the first placement state, the bracket 2 is supported on the back of the protective shell 1 in a first supporting posture. In the first supporting posture, the vertical projection of the connecting end 221 on the wide side 15 of the protective shell 1 is located in the middle of the wide side 15, and the end of the support plate 22 away from the connecting end 221 is supported on the placement surface, so as to achieve stable support for the terminal device 210 in the first placement state in the folded state and the flattened state.

[0261] like Figure 6c As shown, when the terminal device 210 is in the second placement state and the terminal device 210 is in the folded state, the bracket 2 can also be supported on the back of the protective shell in the first supporting posture, and the vertical projection of the connecting end 221 on the wide side 15 of the protective shell 1 is located in the middle of the wide side 15, so as to achieve stable support for the terminal device 210 in the second placement state in the folded state.

[0262] like Figure 6d As shown, the terminal device 210 is in the second placement state, and the second shell 2114 and the first shell 2111 are located in the same plane. When the terminal device 210 is in the flattened state, the bracket 2 can be supported on the back of the protective shell 1 in the second supporting posture. In the second supporting posture, the vertical projection of the connecting end 221 on the wide side 15 is located on the side of the wide side 15 facing the second shell 2114, and the end of the support plate 22 away from the connecting end 221 is supported on the placement surface, so as to achieve stable support for the terminal device 210 in the second placement state when it is flattened.

[0263] The second shell 2114 and the first shell 2111 are located in the same plane by rotating the second shell 2114 relative to the first shell 2111 toward one side of the protective shell 1 .

[0264] like Figures 6a to 6cAs shown, in the first supporting posture, the vertical projection of the connecting end 221 on the long side 14 of the protective shell 1 is located in the middle of the long side 14, so that when the bracket 2 is supported on the back of the protective shell 1 in the first supporting posture, the support plate 22 can be supported in the middle of the long side 14 and the wide side 15 of the protective shell 1, which is conducive to achieving stable support for the terminal device in the first placement state and in the folded state in the second placement state.

[0265] It should be noted that the bracket 2 can achieve stable support for the device body in different placement states with different supporting postures. For details, please refer to the relevant description above and no further details will be given here.

[0266] Among them, the terminal device 210 can also include a flexible display screen 202, a battery, a circuit board, a camera module, etc. For details, please refer to the relevant description above and no further limitation is made here.

[0267] On the basis of the above, the embodiment of the present application further provides another terminal device component 200, referring to Figure 3 、 Figure 5a and Figure 5b As shown, as described above, the terminal device assembly 200 includes a terminal device 210 and a bracket 2. The terminal device 210 may include a back cover 2113, which is located on the back of the terminal device 210.

[0268] Bracket 2 includes a connecting plate 21, a support plate 22, and a mounting member 23. Mounting member 23 is positioned in the middle of the back of rear cover 2113. The plane of connecting plate 21 is parallel to the back of rear cover 2113, and the middle portion of connecting plate 21 is pivotally mounted on mounting member 23. Support plate 22 is pivotally connected to one end of connecting plate 21. Support plate 22 can rotate relative to connecting plate 21 and form an angle with the back of rear cover 2113. This allows the bracket to be mounted on the terminal device via connecting plate 21 and mounting member 23, supporting terminal device 210 via support plate 22. Furthermore, because mounting member 23 is mounted in the middle of the back of rear cover 2113 and the middle portion of connecting plate 21 is pivotally mounted on mounting member 23, bracket 2 can be mounted in the middle of the back of rear cover 2113, ensuring an aesthetically pleasing installation of bracket 2 on terminal device 210.

[0269] It should be noted that the structure of the terminal device 210 can refer to the relevant description above, and no further details are given here. When the bracket 2 is installed on the back of the back cover 2113, the back cover 2113 can serve as a protective shell 1. The structure of the bracket 2 can refer to the relevant description above, and no further details are given here. The installation of the bracket 2 on the back cover 2113 can refer to the relevant description of the installation of the bracket 2 on the protective shell 1 above, and no further details are given here.

[0270] When the long side of the back cover 2113 and the end of the support plate 22 away from the connecting plate 21 are supported on the placement surface, or when the wide side of the back cover 2113 and the end of the support plate 22 away from the connecting plate 21 are supported on the placement surface, the support plate 22 can be supported on the back side of the back cover 2113, which is conducive to achieving stable support for the terminal device 210.

[0271] When the terminal device 210 is a folding device, the wide side of the back cover 2113 and the end of the support plate 22 away from the connecting plate 21 are supported on the placement surface, and the folding device is in the unfolded state, since the connecting plate 21 is rotatably set on the mounting part 23, and the support plate 22 is rotatably connected to one end of the connecting plate 21, at this time, the supporting position of the connecting end 221 of the support plate 22 on the back side of the back cover 2113 can be adjusted by rotating the connecting plate 21, so that the support plate 22 can be supported on the terminal device 210 at a position close to the center of gravity of the entire terminal device 210, which is conducive to achieving stable support of the terminal device 210 in different placement states by the bracket 2.

[0272] Therefore, the present application also facilitates the bracket 2 to stably support the terminal device 210 in different placement states through the setting of the bracket 2 in another terminal device component 200.

[0273] It should be noted that the long side of the back cover 2113 can refer to the direction of the long side 14 of the protective shell 1, and the wide side of the back cover 2113 can refer to the direction of the wide side 15 of the protective shell 1. In another terminal device assembly 200, when the terminal device 210 and the bracket 2 are in different states, the support posture of the bracket 2 relative to the terminal device 210 can refer to the relevant description above and will not be further elaborated here.

[0274] In the description of the embodiments of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to a fixed connection, an indirect connection via an intermediate medium, internal communication between two components, or an interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in the embodiments of this application based on specific circumstances.

[0275] The terms "first", "second", "third", "fourth", etc. (if any) in the description and claims of the embodiments of this application and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.
