Description

Technical Field

[0001] This application relates to the technical field of terminals, and particularly to a protective shell structure and a terminal device assembly. Background Art

[0002] With the development and popularization of terminal devices, the use of terminal devices such as mobile phones and tablet computers has become more and more extensive. In order to protect terminal devices and prevent them from being damaged by bumps, etc., users generally configure a protective shell structure for terminal devices. The protective shell structure can be sleeved on the outside of the terminal device to protect the terminal device.

[0003] In some application scenarios where the screen of a terminal device needs to be viewed for a long time, such as video calls, live broadcasts, and video viewing, tools such as brackets are often needed to assist in supporting the terminal device. Based on this, users often choose a protective shell structure with a bracket function to be sleeved on the terminal device and used in combination with the terminal device. That is to say, the protective shell structure can include a protective shell and a bracket. The bracket is installed on the protective shell and is movable relative to the protective shell. Through the movement of the bracket relative to the protective shell, the bracket can form an angle with the protective shell and unfold, and the bracket can support the terminal device with the protective shell sleeved thereon on a support surface (for example, a desktop).

[0004] However, as the user's frequency of using the bracket increases, the bracket is repeatedly folded, which easily causes the connection between the bracket and the protective shell to crack. Summary of the Utility Model

[0005] In view of this, this application provides a protective shell structure and a terminal device assembly, which can at least to a certain extent prevent the bracket from breaking or cracking from the bottom plate when the bracket is frequently folded.

[0006] To achieve the above object, this application adopts the following technical solutions:

[0007] In a first aspect, this application provides a protective shell structure, including: a protective shell, a connecting member, a bracket, and a reinforcing plate. The protective shell includes a bottom plate, the bottom plate has opposite outer and inner surfaces, and the bottom plate has a through hole penetrating the inner and outer surfaces. The connecting member includes a connected first connecting section and a second connecting section. The first connecting section passes through the through hole, the second connecting section is fixed to the inner surface and is connected to the inner end of the first connecting section. The bracket is located on the side facing away from the outer surface, and the bracket is rotatably connected to the outer end of the first connecting section. The reinforcing plate includes a connected first reinforcing section and a second reinforcing section. The first reinforcing section is disposed on the side of the second connecting section away from the bottom plate, and the second reinforcing section is disposed on the inner surface and is located on the outer periphery of the second connecting section.

[0008] According to the protective shell structure of the embodiments of the present application, on the one hand, the first reinforcing section can be used to integrally reinforce the second connecting section and the part of the bottom plate corresponding to the second connecting section, improving the structural strength at this position; on the other hand, the second reinforcing section can be used to reinforce the part of the bottom plate located on the outer periphery of the second connecting section, improving the structural strength at this place and preventing the fracture at the position of the outer peripheral edge of the bottom plate corresponding to the second connecting section caused by the deformation of the first connecting section, which is beneficial to improving the service life of the bracket.

[0009] In some embodiments of the present application, a receiving groove recessed from the inner surface towards the outer surface is provided on the inner surface, and the receiving groove extends to communicate with the through hole, and the second connecting section is fixed in the receiving groove. In this way, on the one hand, it can prevent the terminal device with the second connecting section received in the protective shell from being scratched, and at the same time facilitate the fixed installation of the second connecting section.

[0010] In some embodiments of the present application, a reinforcing protrusion is provided at the edge of the bottom wall of the receiving groove, and the reinforcing protrusion extends along the circumferential direction of the receiving groove and is connected to the inner circumferential surface of the receiving groove. In this way, the second connecting section is located in the receiving groove and on the side of the reinforcing protrusion close to the through hole. In this way, the reinforcing protrusion can be used to strengthen the position of the bottom plate corresponding to the groove side wall of the receiving groove, which is beneficial to improving the structural strength at this position and reducing the risk of cracks at this position.

[0011] In some embodiments of the present application, the end surface of the reinforcing protrusion facing away from the outer surface and the inner circumferential surface of the receiving groove define a supporting step, the reinforcing plate is arranged in the receiving groove, and the second reinforcing section is supported on the supporting step. Thus, it is not only beneficial to improve the compactness of the structure, but also beneficial to reduce the height of the area of the second reinforcing plate protruding from the inner surface around the receiving groove, or avoid the reinforcing plate protruding from the area of the inner surface around the receiving groove, so that the scratching of the terminal device protected in the protective shell by the reinforcing plate can be avoided at least to a certain extent.

[0012] In some embodiments of the present application, the end surface of the reinforcing plate facing away from the outer surface is flush with the area of the inner surface around the receiving groove. Such a setting can avoid the scratching of the terminal device protected in the protective shell by the reinforcing plate.

[0013] In some embodiments of the present application, a boss portion is provided on the outer surface of the bottom plate. The vertical projection of the receiving groove on the bottom plate is located within the vertical projection of the boss portion on the bottom plate. In this way, by providing the boss portion, the thickness of the part of the bottom plate at the receiving groove and the whole boss portion can be increased, which is beneficial to improving the structural strength of the bottom plate and at least weakening the risk of the bottom plate breaking to a certain extent.

[0014] In some embodiments of the present application, a reinforcing protrusion is provided at the edge of the bottom wall of the receiving groove. The reinforcing protrusion extends along the circumferential direction of the receiving groove and is connected to the inner circumferential surface of the receiving groove. The minimum distance between the side surface of the reinforcing protrusion facing the first connecting section and the side surface of the boss portion is greater than 0.75 mm. In this way, the reinforcing protrusion can be used to reinforce the position of the bottom plate corresponding to the side wall of the receiving groove, which is beneficial to improving the structural strength at this position and reducing the risk of cracks at this position.

[0015] To prevent the problem of affecting the assembly area between the second connecting section and the receiving groove and increasing the cost due to the excessive minimum distance between the side surface of the above-mentioned reinforcing protrusion facing the first connecting section and the side surface of the boss portion, exemplarily, the minimum distance between the side surface of the reinforcing protrusion facing the first connecting section and the side surface of the boss portion is less than or equal to 1.5 mm.

[0016] In some embodiments of the present application, the protective shell structure further includes an adhesive layer. The first reinforcing section and the second connecting section are bonded through the adhesive layer, and the second reinforcing section and the reinforcing protrusion are bonded through the adhesive layer. The advantage of adhesive connection is that the adhesive coverage area is wide, the distribution is uniform, it has strong adhesion and sealing performance, and the operation is simple.

[0017] In some embodiments of the present application, the first reinforcing section and the second connecting section are connected by welding. The welding process is simple, and the connection strength between the first reinforcing section and the second connecting section is high.

[0018] In some embodiments of the present application, the connecting member includes a mating portion. The mating portion has a shaft hole. The mating portion is connected to the outer end of the first connecting section. A pivot shaft is provided on the bracket, and the pivot shaft is rotatably connected to the shaft hole. In this way, the rotational connection between the bracket and the bottom plate can be realized.

[0019] In some embodiments of the present application, in the direction parallel to the bottom plate, the mating portion is located on the side of the first connecting section close to the second connecting section. The cross-sectional area of the through hole is larger than the cross-sectional area of the first connecting section. A protruding portion protruding towards the inside of the through hole is provided on the inner circumferential wall of the through hole. In the plane parallel to the bottom plate, the orthographic projection of the protruding portion overlaps with the orthographic projection of the mating portion. The protruding portion is located on the side of the first connecting section close to the second connecting section. In this way, the space on the side of the mating portion close to the inside of the protective shell can be fully utilized to arrange the protruding portion. The setting of the protruding portion can limit the deformation of the first connecting section in the direction away from the support and away from the outer surface due to the action of the thrust F2, thereby reducing the deformation amount of the first connecting section, and further reducing the deformation of the second connecting section and the bottom plate corresponding to the second connecting section.

[0020] In some embodiments of the present application, the cross-sectional area of the through hole is larger than that of the first connecting section, and a protruding portion protruding towards the inside of the through hole is provided on the inner peripheral wall of the through hole. The protruding portion is located on the side of the first connecting section close to the second connecting section. The distance between the protruding portion and the first connecting section is greater than 0 and less than 2 mm. Such a setting can enable the protruding portion to well limit the deformation of the first connecting section in the direction away from the bracket and towards the inner surface under the action of the thrust F, thereby reducing the deformation amount of the first connecting section, and further reducing the deformation of the second connecting section and the bottom plate corresponding to the second connecting section.

[0021] In some embodiments of the present application, the bracket can be switched between a supporting state and a storage state. In the storage state, the bracket is stacked on the bottom plate. In the supporting state, the angle between the bracket and the bottom plate is greater than 0° and less than 180°. During the process of the bracket rotating relative to the bottom plate and in the supporting state, the shaft hole and the pivot shaft are in interference fit. In this way, when the bracket and the bottom plate are opened to any angle between greater than 0° and less than 180°, the bracket can be in the supporting state.

[0022] In some embodiments of the present application, the shaft hole includes a first mating surface, the pivot shaft includes a mating section, the mating section includes a second mating surface, and during the process of the bracket rotating relative to the bottom plate and in the supporting state, the first mating surface and the second mating surface are kept in abutment. The interference fit between the shaft hole and the pivot shaft is realized.

[0023] In some embodiments of the present application, at least one of the first mating surface and the second mating surface has a groove. The protective shell structure further includes a lubricating medium, and the lubricating medium is arranged in the groove. Therefore, when the second mating surface rotates relative to the first mating surface, the lubricating medium plays a lubricating role and reduces the wear between the first mating surface and the second mating surface when the bracket rotates.

[0024] In some embodiments of the present application, the inner peripheral surface of the shaft hole includes a first arc surface and a first mating surface that are circumferentially distributed along the shaft hole and are connected. The first mating surface is located on the inner peripheral side of the cylindrical surface where the first arc surface is located, and the first mating surface is a plane. The pivot shaft includes a mating section, and the mating section includes a second plane and a second mating surface that are circumferentially distributed along the pivot shaft and are connected. The second mating surface is an arc surface, and the second plane is located on the inner peripheral side of the cylindrical surface where the second mating surface is located. In the storage state, the first mating surface is adapted to the second plane, and the first arc surface is adapted to the second mating surface. During the process of the bracket rotating relative to the bottom plate and in the supporting state, the first mating surface and the second mating surface are kept in abutment. Therefore, when the bracket switches from the supporting state to the storage state, as the bracket gets closer and closer to the storage state, under the action of inertia, the pivot shaft can easily switch to the storage state, thereby giving the user a good feel and a better user experience.

[0025] In some embodiments of the present application, the bottom plate has an avoidance hole for avoiding the camera module of the terminal device. The bracket is annular and has a storage state. In the storage state, the bracket is stacked on the bottom plate and surrounds the avoidance hole. Thus, the structural layout is reasonable.

[0026] In some embodiments of the present application, the protective shell structure further includes a protective case and a protective cover. One end of the protective case is rotatably connected to one end of the protective cover, and the other end of the protective case is rotatably connected to the other end of the protective cover. In this way, the protective shell structure can be used on a folding screen terminal.

[0027] In a second aspect, the present application provides a terminal device assembly, including: a terminal device and a protective shell structure. The protective shell structure is the protective shell structure in any of the above technical solutions. The protective shell covers at least a part of the terminal device.

[0028] Since the terminal device assembly provided by the embodiments of the present application includes the protective shell structure in any of the above technical solutions, the two can solve the same technical problems and achieve the same technical effects.

[0029] In some embodiments of the present application, the terminal device is a folding screen terminal and includes a support device and a display screen. The support device includes a first housing, a second housing, and a rotating assembly. The rotating assembly is connected between the first housing and the second housing and allows the first housing and the second housing to rotate relative to each other. The display screen is supported by the first housing, the second housing, and the rotating assembly. The protective case covers the first housing, the protective shell covers the second housing, and the protective cover covers the rotating assembly. BRIEF DESCRIPTION OF THE DRAWINGS

[0085] In order to facilitate the user to use the terminal device 200 and be able to use the protective shell structure 100 to assist in supporting the terminal device 200. Please continue to refer to Figure 5 and Figure 6 , the protective shell structure 100 further includes a bracket 3.

[0086] The bracket 3 is located on the side where the outer surface 112 faces. The bracket 3 is rotatable relative to the bottom plate 11. By the relative rotation of the bracket 3 and the bottom plate 11, the bracket 3 can be rotated relative to the bottom plate 11 to the storage state, or the bracket 3 can be rotated relative to the bottom plate 11 to the support state. That is to say, the bracket 3 has a storage state and a support state. When the bracket 3 is in the storage state, please continue to refer to Figure 5, the bracket 3 and the bottom plate 11 are stacked. That is, the included angle between the bracket 3 and the bottom plate 11 is 0°. When the bracket 3 is in the supporting state, please refer to Figure 7 , Figure 7 is the schematic diagram of the protective shell structure 100 shown in Figure 5 when the bracket 3 is in the supporting state. The value range of the included angle α between the bracket 3 and the bottom plate 11 is greater than 0° and less than 180°. In this way, in the supporting state, the bracket 3 and the protective shell 1 can form a triangular structure, and the end of the bracket 3 far from the rotation center line and one side edge of the protective shell 1 can be used to jointly support on the supporting surface, so as to facilitate the support of the terminal device 200.

[0087] Next, the specific rotational connection manner between the bracket 3 and the bottom plate 11 will be introduced in detail.

[0088] Please refer to Figure 8 , Figure 8 is the enlarged view of the structure shown in Figure 6 circled at M. The protective shell structure 100 further includes a connecting member 2. The material of the connecting member 2 includes but is not limited to metal or plastic.

[0089] The connecting member 2 includes a first connecting section 21, a mating portion 23 and a second connecting section 22.

[0090] The first connecting section 21 is sheet-shaped. The shape of the first connecting section 21 includes but is not limited to rectangular sheet-shaped, triangular sheet-shaped or special-shaped sheet-shaped.

[0091] The bottom plate 11 has a through hole 113 penetrating the inner surface 111 and the outer surface 112. The shape of the through hole 113 includes but is not limited to semi-circular, circular, polygonal or special-shaped. The first connecting section 21 passes through the through hole 113.

[0092] The mating portion 23 is connected to the outer end of the first connecting section 21. The mating portion 23 has a shaft hole 231. A pivot shaft 31 is provided on the bracket 3. The pivot shaft 31 is rotatably connected in the shaft hole 231. In this way, the rotational connection between the bracket 3 and the bottom plate 11 can be realized. Of course, the present application is not limited to this. In other embodiments, the shaft hole 231 can also be provided on the bracket 3, and the mating portion 23 can be used as the pivot shaft 31 or a pivot shaft 31 can be provided on the mating portion 23. As long as it is ensured that the bracket 3 can be rotatably connected to the outer end of the first connecting section 21.

[0093] Exemplarily, the mating portion 23 and the first connecting section 21 can be integrally formed, which is beneficial to improving the connection strength between the mating portion 23 and the first connecting section 21, simplifying the processing technology and reducing the manufacturing cost. Also exemplarily, the connection manner between the mating portion 23 and the first connecting section 21 can also be adhesive bonding, welding, snap connection or screw connection, etc.

[0094] The second connecting section 22 is sheet-shaped. The shape of the second connecting section 22 includes but is not limited to a rectangular sheet shape, a semi-circular sheet shape, a triangular sheet shape, or an irregular sheet shape.

[0095] The second connecting section 22 is connected to the inner end of the first connecting section 21. And the second connecting section 22 is fixed to the inner surface 111. In this way, the second connecting section 22 is located on the side facing the inner surface 111 of the bottom plate 11. By fixing the second connecting section 22 to the side facing the inner surface 111 of the bottom plate 11, on the one hand, the assembly between the connecting member 2 and the bottom plate 11 can be realized, and on the other hand, the connecting member 2 can be hidden inside the protective shell 1, improving the aesthetic appearance.

[0096] Wherein, the outer end of the first connecting section 21 refers to the end of the first connecting section 21 facing away from the inside of the protective shell 1. The inner end of the first connecting section 21 refers to the end of the first connecting section 21 close to the inside of the protective shell 1.

[0097] Exemplarily, the second connecting section 22 and the first connecting section 21 can be integrally formed parts, which is beneficial to improving the connection strength between the second connecting section 22 and the first connecting section 21, simplifying the processing technology, and reducing the manufacturing cost. Also exemplarily, the connection manner between the second connecting section 22 and the first connecting section 21 can also be adhesive connection, welding, snap connection, or screw connection, etc.

[0098] In some specific examples, the mating portion 23, the first connecting section 21, and the second connecting section 22 can be integrally formed parts. Thus, the processing technology of the connecting member can be simplified, and the manufacturing cost can be reduced. For example, the sheet material is bent to form the connecting member.

[0099] The connection manner between the second connecting section 22 and the bottom plate 11 includes but is not limited to rivet connection, bolt connection, or adhesive connection.

[0100] In some specific examples, please continue to refer to Figure 8 , a first connection hole 13 is provided on the bottom plate 11. A second connection hole 221 is provided on the second connecting section 22. The protective shell structure 100 further includes a fixing member 52, and the fixing member 52 passes through the first connection hole 13 and the second connection hole 221 to connect the bottom plate 11 and the second connecting section 22. The fixing member 52 includes but is not limited to rivets, screws, etc.

[0101] On this basis, in some embodiments, in order to prevent the fixing member 52 and the first connection hole 13 from affecting the appearance of the protective shell structure 100, the protective shell structure 100 can further include a decorative member 51. The decorative member 51 is located on the side facing the outer surface 112 and covers the first connection hole 13 and the fixing member 52. The material of the decorative member 51 includes but is not limited to metal or plastic.

[0102] Exemplarily, the fixing member 52 and the decorative member 51 can be an integral part. In this way, the connection strength between the fixing member 52 and the decorative member 51 can be improved, the processing technology can be simplified, and the manufacturing cost can be reduced. Also exemplarily, the fixing member 52 and the decorative member 51 can also be connected by means such as welding or gluing. Among them, when the fixing member 52 and the decorative member 51 are connected, exemplarily, the fixing member 52 can be a rivet.

[0103] In other embodiments, the protective shell structure 100 may also not be provided with the decorative member 51, and the surface where the second connecting section 22 is attached to the bottom plate 11 is adhesively connected or spot welded.

[0104] Exemplarily, please continue to refer to Figure 8 , the connection part between the first connecting section 21 and the second connecting section 22 is an arc structure 211. In this way, the stress concentrated at the connection part between the first connecting section 21 and the second connecting section 22 can be dispersed, thereby reducing the occurrence of stress concentration and preventing the connecting member 2 from breaking at the connection part when stressed. In other embodiments, the arc structure 211 may not be provided at the connection part between the first connecting section 21 and the second connecting section 22.

[0105] Based on the above embodiments, since the second connecting section 22 is provided on the inner surface 111, and the inner surface 111 faces the second housing 2022. Therefore, in order to prevent the second connecting section 22 from scratching the second housing 2022, and at the same time to facilitate the fixed installation of the second connecting section 22, the inner surface 111 has a receiving groove 115 recessed towards the outer surface 112, and the receiving groove 115 extends to communicate with the through hole 113, and the second connecting section 22 is fixed in the receiving groove 115.

[0106] Of course, it can be understood that in other embodiments, the receiving groove 115 may not be provided on the inner surface 111.

[0107] Considering that the two ends of the first connecting section 21 are respectively connected with the matching part 23 and the second connecting section 22, in order to facilitate the assembly of the connecting member 2 and the bottom plate 11, exemplarily, the cross-sectional area of the through hole 113 can be larger than the cross-sectional area of the first connecting section 21. In other embodiments, the cross-sectional area of the through hole 113 can also be equal to the cross-sectional area of the first connecting section 21.

[0108] With the thin design of the terminal device 200, the protective shell structure 100 also develops towards thinness. Therefore, the wall thickness of the bottom plate 1 is relatively thin, and together with the above-mentioned setting of the receiving groove 115, the thickness of the bottom plate 1 at the receiving groove 115 is even thinner. When an external force drives the bracket 3 to rotate around the shaft hole 231, please continue to refer to Figure 8, the bracket 3 is subjected to a tensile force F1. The tensile force F1 is substantially tangent to the rotation path of the bracket 3. Since the first connecting section 21 is rotationally connected to the bracket 3, when an external force drives the bracket 3 to rotate around the shaft hole 231, the first connecting section 21 is subjected to a thrust force F2. The thrust force F2 is a force in the radial direction of the rotation path of the bracket 3, and the thrust force F2 is in a direction away from the bracket 3 and toward the inner surface 112. The thrust force F2 is perpendicular to the tensile force F1. Under the action of the thrust force F2, the first connecting section 21 is deformed. In particular, when the cross-sectional area of the through hole 113 is larger than the cross-sectional area of the first connecting section 21, the deformation of the first connecting section 21 is more serious. Due to the deformation of the first connecting section 21, under the drive of the first connecting section 21, the second connecting section 22 and the part of the bottom plate 11 corresponding to the receiving groove 115 will be deformed as a whole along the Figure 8 direction of the arrow F3 in, resulting in a crack at one end A of the bottom plate 11 away from the through hole 113 in the receiving groove 115. If the user repeatedly and frequently uses the bracket 3, it is easy to cause the crack to expand, and then the position of the bottom plate 11 corresponding to the receiving groove 115 is fractured, resulting in the part of the bracket 3, the connecting member 2, and the bottom plate 11 corresponding to the receiving groove 115 being separated from the rest of the protective shell structure 100 due to fracture, causing the failure of the bracket 3.

[0109] Of course, it can be understood that when the receiving groove 115 is not provided on the bottom plate 11, based on the foregoing force analysis, cracks are also likely to occur at the position of the outer peripheral edge of the bottom plate 11 corresponding to the second connecting section 22, causing fracture.

[0110] Based on this, in order to solve the above technical problems, please refer to Figure 9 , Figure 9 is a partial cross-sectional schematic view of the protective shell structure 100 provided in some other embodiments of the present application. A convex platform portion 114 is provided on the outer surface 112 of the bottom plate 11. The vertical projection of the second connecting section 22 on the bottom plate 11 is located within the vertical projection of the convex platform portion 114 on the bottom plate 11. In this way, by providing the convex platform portion 114, the thickness of the part of the bottom plate 11 at the second connecting section 22 and the whole of the convex platform portion 114 can be increased, thereby being beneficial to improving the structural strength of the bottom plate 11 and at least reducing the risk of fracture of the bottom plate 11 to a certain extent.

[0111] Exemplarily, the convex platform portion 114 and the bottom plate 11 can be integrally formed, which is beneficial to improving the connection strength between the convex platform portion 114 and the bottom plate 11, simplifying the processing process, and reducing the manufacturing cost. Another exemplarily, the connection manner between the convex platform portion 114 and the bottom plate 11 can also be adhesive bonding, welding, snap connection or screw connection, etc.

[0112] On this basis, please continue to refer to Figure 9, when there is a receiving groove 115 on the inner surface 111, the vertical projection of the receiving groove 115 on the bottom plate 11 is located within the vertical projection of the boss portion 114 on the bottom plate 11. In this way, by providing the boss portion 114, the thickness of the portion of the bottom plate 11 at the receiving groove 115 and the overall thickness of the boss portion 114 can be increased, which is beneficial to improving the structural strength of the bottom plate 11 and at least weakening the risk of fracture of the bottom plate 11 to a certain extent.

[0113] Although the provision of the boss portion 114 can improve the structural strength of the bottom plate 11 to a certain extent, considering that the provision of the boss portion 114 will affect the thickness of the bottom plate 11, which is contrary to the trend of thinning of the protective shell structure 100, therefore, the outer peripheral dimension of the boss portion 114 is generally set to be relatively small. In this way, the minimum distance h between the side surface of the boss portion 114 and the groove side wall of the receiving groove 115 is relatively small, and h is about 0.75 mm. Among them, in Figure 9 In the specific example shown, the minimum distance h is the distance between one end of the side surface of the boss portion 114 close to the outer surface 112 and one end of the groove side wall of the receiving groove 115 close to the outer surface 112. When the bracket 3 is repeatedly used for a long time, cracks will still be generated at this position. If the user repeatedly and frequently uses the bracket 3, it is easy to cause the cracks to expand, and there will still be a fracture at the position of the bottom plate 11 corresponding to the receiving groove 115, which will further cause the corresponding parts of the bracket 3, the connecting member 2, and the bottom plate 11 corresponding to the receiving groove 115 to be separated from the rest of the protective shell structure 100 due to fracture, resulting in the failure of the bracket 3.

[0114] To solve the technical problems existing in the protective shell structure 100 shown in any of the above embodiments, please refer to Figure 10 and Figure 11 , Figure 10 is an exploded view of the protective shell structure 100 provided in some other embodiments of the present application, Figure 11 is a schematic cross-sectional structure view of the protective shell structure shown in Figure 10 at the B-B line. The difference between this embodiment and the above embodiment is that: the protective shell structure 100 further includes a reinforcing plate 4.

[0115] The reinforcing plate 4 is in the shape of a flat plate. The shape of the reinforcing plate 4 includes but is not limited to a rectangle, a triangle or a special shape. The material of the reinforcing plate 4 includes but is not limited to metal or plastic.

[0116] The reinforcing plate 4 includes a first reinforcing section 41 and a second reinforcing section 42 which are connected. The first reinforcing section 41 is disposed on the side of the second connecting section 22 away from the bottom plate 11, and is laminated and fixedly connected to the second connecting section 22. The second reinforcing section 42 is disposed on the inner surface 111 and is located on the outer periphery of the second connecting section 22. In this way, on the one hand, the first reinforcing section 41 can be used to reinforce the second connecting section 22 and the corresponding part of the bottom plate 11 corresponding to the second connecting section 22 as a whole, improving the structural strength at this position; on the other hand, the second reinforcing section 42 can be used to reinforce the part of the bottom plate 11 located on the outer periphery of the second connecting section 22, improving the structural strength at this place and preventing the fracture at the position of the outer peripheral edge of the bottom plate 11 corresponding to the second connecting section 22 caused by the deformation of the first connecting section 21, thereby being beneficial to improving the service life of the bracket 3.

[0117] Exemplarily, the first reinforcing section 41 and the second reinforcing section 42 can be integrally formed parts, which is beneficial to improving the connection strength between the first reinforcing section 41 and the second reinforcing section 42, simplifying the processing technology and reducing the manufacturing cost. Also exemplarily, the connection manner between the first reinforcing section 41 and the second reinforcing section 42 can also be adhesive bonding, welding, snap connection or screw connection, etc.

[0118] On this basis, when the above-mentioned receiving groove 115 is provided on the bottom plate 11, please continue to refer to Figure 11 , in some embodiments, a reinforcing protrusion 116 is provided at the edge of the bottom wall of the receiving groove 115. The reinforcing protrusion 116 extends along the circumferential direction of the receiving groove 115 and is connected to the inner circumferential surface of the receiving groove 115. The second connecting section 22 is located in the receiving groove 115 and is located on the side of the reinforcing protrusion 116 close to the through hole 113. In this way, the reinforcing protrusion 116 can be used to strengthen the position of the bottom plate 11 corresponding to the side wall of the receiving groove 115, thereby being beneficial to improving the structural strength at this position and reducing the risk of fracture at this position.

[0119] Exemplarily, the reinforcing protrusion 116 and the bottom plate 11 can be integrally formed parts, which is beneficial to improving the connection strength between the reinforcing protrusion 116 and the bottom plate 11, simplifying the processing technology and reducing the manufacturing cost. Also exemplarily, the connection manner between the reinforcing protrusion 116 and the bottom plate 11 can also be adhesive bonding, welding, snap connection or screw connection, etc.

[0120] On this basis, please continue to refer to Figure 11, one end face of the reinforcing protrusion 116 facing away from the outer surface 112 and the inner peripheral surface of the receiving groove 115 define a support step 1161. That is to say, one end face of the reinforcing protrusion 116 facing away from the outer surface 112 is lower than the area of the inner surface 111 around the receiving groove 115 to form the support step 1161. In this way, the reinforcing plate 4 can be disposed in the receiving groove 115, and the second reinforcing section 42 is supported on the support step. Thereby, it is not only beneficial to improve the structural compactness, but also beneficial to reduce the height of the second reinforcing plate 4 protruding from the area of the inner surface 111 around the receiving groove 115, or to prevent the reinforcing plate 4 from protruding from the area of the inner surface 111 around the receiving groove 115, so that the scraping of the second housing 2022 protected in the protective case 1 by the reinforcing plate 4 can be avoided to at least a certain extent.

[0121] On this basis, please continue to refer to Figure 11 , one end face of the reinforcing plate 4 facing away from the outer surface 112 is flush with the area of the inner surface 111 around the receiving groove 115. Such a setting can, on the one hand, avoid the scraping of the second housing 2022 protected in the protective case 1 by the reinforcing plate 4; on the other hand, it can also avoid the problem of setting the thicknesses of the reinforcing plate 4 and the second connecting section 22 too small due to the fact that one end face of the reinforcing plate 4 facing away from the outer surface 112 is lower than the area of the inner surface 111 around the receiving groove 115, so as to be beneficial to ensuring that the thicknesses of the reinforcing plate 4 and the second connecting section 22 are relatively large, and further ensuring their structural strength.

[0122] In other embodiments, one end face of the reinforcing plate 4 facing away from the outer surface 112 may also be lower than the area of the inner surface 111 around the receiving groove 115. In this way, the problem that the thickness dimensions of the reinforcing plate 4 are inconsistent due to reasons such as assembly error or processing error, and the reinforcing plate 4 protrudes from the receiving groove 115 to scrape the second housing 2022 can be avoided.

[0123] Based on any of the above embodiments having the reinforcing protrusion 116, due to the setting of the above-mentioned reinforcing protrusion 116, the minimum distance h between the side surface of the reinforcing protrusion 116 facing the first connecting section 21 and the side surface of the boss portion 114 is greater than 0.75 mm. In this way, the reinforcing protrusion 116 can be used to strengthen the position of the bottom plate 11 corresponding to the groove side wall of the receiving groove 115, which is beneficial to improving the structural strength at this position and reducing the risk of cracks occurring at this position.

[0124] On this basis, exemplarily, in order to prevent the problem that the minimum distance h between the side surface of the reinforcing protrusion 116 facing the first connecting section 21 and the side surface of the boss portion 114 is set too large, which affects the assembly area between the second connecting section 22 and the receiving groove 115 and increases the cost, exemplarily, the minimum distance h between the side surface of the reinforcing protrusion 116 facing the first connecting section 21 and the side surface of the boss portion 114 is less than or equal to 1.5 mm.

[0125] Exemplarily, the minimum distance between the side surface of the reinforcing protrusion 116 facing the first connecting section 21 and the side surface of the boss portion 114 can be 0.79 mm, 0.8 mm, 0.82 mm, 0.86 mm, 0.88 mm, 0.9 mm, 1.0 mm, 1.1 mm, 1.2 mm, 1.3 mm, 1.4 mm, 1.5 mm, 1.6 mm, 1.7 mm, 1.8 mm, or 1.9 mm.

[0126] Exemplarily, the inner peripheral surface of the reinforcing protrusion 116 is similar in contour to the outer peripheral wall of the second connecting section 22. With this setting, the second connecting section 22 and the reinforcing protrusion 116 are more adaptable after assembly, reducing the assembly difficulty.

[0127] It should be understood that the foregoing description is made by taking the entire reinforcing plate 4 being located within the receiving groove 115 as an example. In some other embodiments, the first reinforcing section 41 is located within the receiving groove 115, and the second reinforcing section 42 is located outside the receiving groove 115. Or, in other embodiments, the entire reinforcing plate 4 is located outside the receiving groove 115, and the second reinforcing section 42 is located outside the receiving groove 115.

[0128] In some embodiments, the protective shell structure 100 further includes an adhesive layer ( Figure 11 not shown in the figure). The first reinforcing section 41 and the second connecting section 22, as well as the second reinforcing section 42 and the reinforcing protrusion 116, are bonded through the adhesive layer. The advantage of adhesive connection is that the adhesive coverage area is wide, the distribution is uniform, it has strong adhesive force and sealing performance, and the operation is simple.

[0129] In some other embodiments, the first reinforcing section 41 and the second connecting section 22 are connected by welding. The welding process is simple, and the connection strength between the first reinforcing section 41 and the second connecting section 22 is high.

[0130] On this basis, exemplarily, the second reinforcing section 42 and the reinforcing protrusion 116 may be in abutting contact. Based on the advantages of the welded connection between the first reinforcing section 41 and the second connecting section 22, such as high connection strength and wide welding area, the abutting contact between the second reinforcing section 42 and the reinforcing protrusion 116 can also play a role in strengthening the bottom plate 11. Moreover, the abutting contact between the second reinforcing section 42 and the reinforcing protrusion 116 simplifies the connection relationship and reduces the processing cost.

[0131] Also exemplarily, the second reinforcing section 42 and the reinforcing protrusion 116 may be welded.

[0132] In some embodiments, please continue to refer to Figure 11 , in the direction parallel to the bottom plate 11, the mating portion 23 is located on the side of the first connecting section 21 close to the second connecting section 22. On the inner peripheral wall of the through hole 113, there is a protruding portion 1131 protruding towards the inside of the through hole 113.

[0133] The protruding portion 1131 is located on the side of the first connecting section 21 close to the second connecting section 22. In the plane parallel to the bottom plate 11, the orthographic projection of the protruding portion 1131 overlaps with the orthographic projection of the mating portion 23. In this way, the space on the side of the mating portion 23 close to the inside of the protective shell 1 can be fully utilized to arrange the protruding portion 1131. The setting of the protruding portion 1131 can limit the deformation of the first connecting section 21 in the direction away from the bracket 3 and away from the outer surface 112 due to the action of the thrust F2, thereby reducing the deformation amount of the first connecting section 21, and further reducing the deformation of the second connecting section 22 and the bottom plate 11 corresponding to the second connecting section 22.

[0134] It should be noted that, in the plane parallel to the bottom plate 11, the overlap of the orthographic projection of the protruding portion 1131 and the orthographic projection of the mating portion 23 means that in the plane parallel to the bottom plate 11, the orthographic projection of the protruding portion 1131 completely coincides with the orthographic projection of the mating portion 23, or it may also mean that in the plane parallel to the bottom plate 11, the orthographic projection of the protruding portion 1131 partially coincides with the orthographic projection of the mating portion 23.

[0135] Furthermore, the distance d between the protruding portion 1131 and the first connecting section 21 is greater than 0 and less than 2 mm. Exemplarily, the distance between the protruding portion 1131 and the first connecting section 21 can be 0.8 mm, 1 mm, 1.1 mm or 1.2 mm. Such a setting can enable the protruding portion 1131 to well limit the deformation of the first connecting section 21 in the direction away from the bracket 3 and towards the inner surface 112 due to the action of the thrust F2, thereby reducing the deformation amount of the first connecting section 21, and further reducing the deformation of the second connecting section 22 and the bottom plate 11 corresponding to the second connecting section 22.

[0136] Exemplarily, the shape of the protrusion 1131 includes but is not limited to a semi-cylindrical shape, a triangular prism shape, or an irregular shape.

[0137] Exemplarily, the protrusion 1131 and the bottom plate 11 may be an integrally formed part, which is beneficial to improving the connection strength between the protrusion 1131 and the bottom plate 11, simplifying the processing technology, and reducing the manufacturing cost. Additionally exemplarily, the connection method between the protrusion 1131 and the bottom plate 11 may also be adhesive bonding, welding, snap connection, or screw connection, etc.

[0138] Based on any of the above embodiments, during the rotation of the pivot shaft 31 relative to the shaft hole 231 and in the supported state, the pivot shaft 31 and the shaft hole 231 are in interference fit. In this way, when the bracket 3 and the bottom plate 11 are opened to any angle α greater than 0° and less than 180°, the bracket 3 can be in the supported state. Therefore, there can be multiple supported states, enabling the adjustment of the support angle of the bracket 3 for the terminal device 200, which is convenient for users.

[0139] Please refer to Figures 12 - 14 , Figure 12 is the three-dimensional view of the pivot shaft 31 shown in Figure 10 ; Figure 13 is the schematic diagram of the fit between the pivot shaft 31 on the bracket 3 and the shaft hole 231 on the connecting member 2 in the stored state shown in Figure 10 ; Figure 14 is the schematic diagram of the fit between the pivot shaft 31 on the bracket 3 and the shaft hole 231 on the connecting member 2 in the supported state shown in Figure 10 . The inner circumferential surface of the shaft hole 231 includes a first arc surface 2312 and a first mating surface 2311 that are circumferentially distributed along the shaft hole 231 and are connected. The first mating surface 2311 is located on the inner circumferential side of the cylindrical surface where the first arc surface 2312 is located. The first mating surface 2311 is a plane.

[0140] The pivot shaft 31 includes a mating section 311. The mating section 311 includes a second plane 3111 and a second mating surface 3112 that are circumferentially distributed along the pivot shaft 31 and are connected. The second mating surface 3112 is an arc surface. The second plane 3111 is located on the inner circumferential side of the cylindrical surface where the second mating surface 3112 is located.

[0141] When the bracket 3 is in the stored state, please refer to Figure 13 , the first mating surface 2311 is adapted to the second plane 3111, and the first arc surface 2312 is adapted to the second mating surface 3112.

[0142] It can be understood that when the bracket 3 is in the retracted state, the first mating surface 2311 being adapted to the second plane 3111 means that the first mating surface 2311 and the second plane 3111 are parallel and face each other, with a gap of 0 therebetween and no abutting relationship therebetween. When the bracket 3 is in the retracted state, the first arc surface 2312 being adapted to the second mating surface 3112 means that the first arc surface 2312 and the second mating surface 3112 are parallel and face each other, with a gap of 0 therebetween and no abutting relationship therebetween. Thus, in the retracted state, there is no damping force between the pivot shaft 31 and the shaft hole 231.

[0143] Please refer to Figure 14 , when the bracket 3 rotates relative to the bottom plate 11 and in the supporting state, the first mating surface 2311 and the second mating surface 3112 are both kept in abutment, so as to achieve an interference fit between the shaft hole 231 and the pivot shaft 31 for locking the bracket 3.

[0144] From the above description, it can be found that when the bracket 3 rotates relative to the bottom plate 11 to any angle, the pivot shaft 31 and the shaft hole 231 are in interference fit, and in the retracted state, the pivot shaft 31 and the shaft hole 231 are adapted to each other. Therefore, when the bracket 3 switches from the supporting state to the retracted state, as the bracket 3 gets closer and closer to the retracted state, under the action of inertia, the pivot shaft 31 can easily switch to the retracted state, thus giving the user a good feel and a better use experience.

[0145] Exemplarily, the first mating surface 2311, the second mating surface 3112, the first arc surface 2312 and the second plane 3111 are all one. One first mating surface 2311 and one first arc surface 2312 form the entire inner circumferential surface of the shaft hole 231. One second mating surface 3112 and one second plane 3111 form the entire outer circumferential surface of the mating section 311.

[0146] Also exemplarily, the first mating surface 2311, the second mating surface 3112, the first arc surface 2312 and the second plane 3111 are all multiple (for example, 2, 3 or 4), and the quantities are equal. Among them, the multiple first mating surfaces 2311 and the multiple first arc surfaces 2312 are alternately arranged in the circumferential direction of the shaft hole 231 and form the entire inner circumferential surface of the shaft hole 231. The multiple second mating surfaces 3112 and the multiple second planes 3111 are alternately arranged in the circumferential direction of the mating section 311 and form the entire outer circumferential surface of the mating section 311.

[0147] In some embodiments, please continue to refer to Figure 12 , there is a groove 31121 on the second mating surface 3112. The number of the grooves 31121 can be one or multiple.

[0148] In Figure 12In the specific example shown, the second mating surface 3112 has a plurality of grooves 31121. The plurality of grooves 31121 are spaced apart in the axial direction of the pivot shaft 31. Each groove 31121 extends along the circumferential direction of the pivot shaft 31.

[0149] The protective shell structure 100 further includes a lubricating medium ( Figure 12 not shown in the figure), and the lubricating medium includes but is not limited to grease. The lubricating medium is disposed in the grooves 31121. When the bracket 3 rotates, frictional force will be generated between the first mating surface 2311 and the second mating surface 3112, and wear will be relatively serious after long-term use. Therefore, when the second mating surface 3112 rotates relative to the first mating surface 2311, the lubricating medium plays a lubricating role, reducing the wear between the first mating surface 2311 and the second mating surface 3112 when the bracket 3 rotates.

[0150] Of course, the present application is not limited thereto. In other embodiments, grooves 31121 may also be provided on the first mating surface 2311. As long as at least one of the first mating surface 2311 and the second mating surface 3112 has grooves 31121.

[0151] In some embodiments of the present application, please refer back to Figure 10 the figure, two fixing ears 32 are provided on the bracket 3. The two fixing ears 32 are oppositely arranged. Each fixing ear 32 has a fixing hole 321. The pivot shaft 31 includes two fixing segments 312. The two fixing segments 312 are disposed at opposite ends of the mating segment 311. The two fixing segments 312 correspond to the two fixing holes 321 one by one. Each fixing segment 312 is fixed in the corresponding fixing hole 321. In this way, the fixed connection between the bracket 3 and the pivot shaft 31 can be realized. Therefore, when the bracket 3 rotates relative to the bottom plate 11, the bracket 3 and the pivot shaft 31 can move synchronously. This setting has a simple structure, is easy to process and manufacture, and is convenient for assembly.

[0152] Of course, the present application is not limited thereto. In other examples, both the fixing ear 32 and the fixing segment 312 can also be one, as long as the fixed connection between the bracket and the pivot shaft can be realized.

[0153] Exemplarily, the shape of the fixing hole 321 includes but is not limited to circular, square, triangular, or irregular. The shape of the fixing segment 312 can be adapted to the shape of the fixing hole 321. Among them, when the fixing hole 321 is circular, the fixing segment 312 can also be circular, and the fixing segment 312 and the fixing hole 321 can be in interference fit.

[0154] Exemplarily, the bracket 3 and the fixing ear 32 can be integrally formed, which can improve the connection strength between the bracket 3 and the fixing ear 32, simplify the processing technology of the two, and reduce costs. Also exemplarily, the bracket 3 and the fixing ear 32 can also be connected by means such as welding, snap connection, screw connection or gluing.

[0155] In some embodiments of the present application, please continue to refer to Figure 10 , the bottom plate 11 has an avoidance hole 117, and the avoidance hole 117 is used to avoid the camera module and the camera decorative part of the terminal device. Based on the above, the bracket 3 is stacked on the bottom plate 11, and in the storage state, the bracket 3 can be arranged around the avoidance hole 117. Thus, the structural layout is reasonable. In other examples, in the storage state, the bracket 3 can also be covered on the outer surface 112 of the bottom plate 11 but not around the avoidance hole 117.

[0156] In addition, for the solution where there is an antenna radiator near the camera module of the terminal device 200, for example, for the solution where there is an antenna radiator on the camera decorative part, the arrangement of the bracket 3 around the avoidance hole 117 can play a role in clearance.

[0157] For the protective shell structure 100 of the above embodiments of the present application, 12,000 times of repeated folding tests of the bracket 3 are carried out. After experimental verification, the connection between the bracket 3 and the bottom plate 11 is good and there is no fracture.

[0158] In the description of this specification, specific features, structures, materials or characteristics can be combined in a suitable manner in any one or more embodiments or examples.

[0159] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, and are not intended to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the various embodiments of the present application.
