[0119] See also Fig.10 , Fig.11 and Fig.12 , Fig.10 for Fig. 9 A schematic diagram of the structure of the support member 20, Fig.11 for Fig.10 A magnified schematic diagram of the middle II region. Fig.12 This is a schematic structural diagram of the support member 20 of the bracket assembly 100 provided in an embodiment of the present application being in the second position.

[0120] See also Fig.10 and Fig.11 The support member 20 includes a first clamping portion 21, a second clamping portion 23 and a support portion 25. One end of the first clamping portion 21 is connected to one end of the second clamping portion 23.

The support member 20 detachably assembles the fixed shaft 15 in the mounting groove 27 through the opening 271. The support member 20 is rotatably connected to the fixed shaft 15, and the support portion 25 connects the first clamping portion 21 and the second clamping portion 23. The support member 20 has elasticity that can meet the assembly of the support member 20 and the rotation of the support member 20 relative to the fixed shaft 15. The material of the support member 20 can be plastic. In some embodiments, when the material of the support member 20 does not affect the performance of the terminal device 200 (for example, does not affect the heat dissipation performance of the terminal device 200 during wireless charging), the material of the support member 20 can also be metal or alloy.

[0121] When the support member 20 is assembled on the housing 10, the support member 20 can rotate around the fixed axis 15. When the support member 20 is received in the receiving groove 111, that is, the support portion 25 is close to the housing 10, the support member 20 is located in the first position; when the support member 20 rotates around the fixed axis 15, that is, the support portion 25 rotates in a direction away from the housing 10, at this time, the support member 20 is located in the second position. Therefore, the support member 20 can switch between the first position where the support portion 25 is close to the housing 10 and the second position where the support portion 25 is away from the housing 10. When the support member 20 is located in the first position, the bracket assembly 100 is easy to carry; when the support member 20 is located in the second position, the bracket assembly 100 can be used to achieve the supporting function.

[0122] When the support member 20 is assembled on the housing 10 and is located at the first position, the support portion 25 is accommodated in the first area 1112, the first clamping portion 21 is accommodated in the second area 1114, the second clamping portion 23 is located on the side of the first clamping portion 21 away from the second area 1114, and the decorative member 30 is accommodated in the third area 1116 and is spaced from the second clamping portion 23. The second area 1114 is further recessed along the third direction L3 relative to the first area 1112 to reserve sufficient avoidance space for the rotation of the support member 20. In this embodiment, the second area 1114 is a through hole.

[0123] The cross section of one end of the first clamping portion 21 away from the supporting portion 25 along the perpendicular direction L1 is generally arc-shaped, and the first clamping portion 21 is used to cover the fixed shaft 15; the surface of the second clamping portion 23 away from the first clamping portion 21 and the surface of the supporting portion 25 away from the first area 1112 are equivalent to the appearance surface of the supporting member 20. When the supporting member 20 is located in the second position, the supporting portion 25 rotates in the direction away from the housing 10 until the supporting member 20 abuts against the decorative member 30, that is, the decorative member 30 can be used to play a stop role.

[0125] The fixed shaft 15 includes a sliding surface 153 and a convex surface 155. The sliding surface 153 and the convex surface 155 are arranged to form the fixed shaft 15. The sliding surface 153 and the convex surface 155 are connected by an arc surface transition. The sliding surface 153 is closer to the receiving groove 111 relative to the convex surface 155, and the convex surface 155 is away from the receiving groove 111. The cross section of the fixed shaft 15 along the perpendicular direction L1 is non-circular. In this embodiment, the cross section of the fixed shaft 15 along the perpendicular direction L1 is approximately "water drop shape".

[0126] The sliding surface 153 is used to contact the first clamping portion 21, and the protruding surface 155 is used to contact the second clamping portion 23. Fig.13 and Fig.14 When the support member 20 is located at the first position, the first clamping portion 21 covers the sliding surface 153, the second clamping portion 23 abuts against the sliding surface 153, and the protruding surface 155 is located between the first clamping portion 21 and the second clamping portion 23 and faces one side of the opening 271. Fig.15 and Fig.16 When the support member 20 is converted from the first position to the second position, the first clamping portion 21 slides relative to the sliding surface 153 and covers the sliding surface 153, and the second clamping portion 23 slides relative to the sliding surface 153 to the convex surface 155 until it exceeds the top of the convex surface 155. At this time, the support member 20 can automatically complete the conversion process. Fig.17 and Fig.18 When the support member 20 is in the second position, the first clamping portion 21 covers the sliding surface 153, the second clamping portion 23 contacts the sliding surface 153, and the convex surface 155 is located between the first clamping portion 21 and the second clamping portion 23 and on the side away from the opening 271. When the support member 20 is converted from the second position to the first position, the action process is similar to the above process and will not be repeated here. Among them, the sliding surface 153 and the convex surface 155 are both arc surfaces, which is conducive to the smooth rotation of the support member 20; the setting of the convex surface 155, when the contact point between the second clamping portion 23 and the convex surface 155 exceeds the top of the convex surface 155, is conducive to the support member 20 automatically completing the conversion process without applying additional force to the support member 20.

[0127] The fixed shaft 15 is provided with a slot 151, which is provided on the sliding surface 153 and is located in the area of ​​the fixed shaft 15 close to the third area 1116. The first clamping portion 21 includes a first protrusion 212, which protrudes toward the mounting groove 27 and is rotatably disposed in the slot 151.

[0128] When the support member 20 switches between the first position and the second position, the first protrusion 212 slides synchronously in the slot 151. The cross section of the slot 151 along the first direction L1 is an arc surface, and when the first protrusion 212 slides in the slot 151, it is conducive to the first protrusion 212 to slide more smoothly relative to the slot. Among them, when the bracket assembly 100 realizes the supporting function, the support member 20 and the shell 10 have an angle with the bearing surface S. If a force is applied to the terminal device 200, such as clicking the display screen 201, the terminal device 200 is subjected to a pressing force on the support member 20, and the first protrusion 212 of the support member 20 can be against the slot wall of the slot 151, which can increase the difficulty of the fixed shaft 15 to disengage from the opening 271, thereby increasing the pressure resistance of the bracket assembly 100.

[0129] Please combine Fig.19 and Fig. 20 , Fig.19 for Fig. 9 A schematic diagram of the structure of the housing 10, Fig. 20 for Fig.19 Schematic enlargement of region VI.

[0130] Specifically, the card slot 151 includes a first slot wall 1511, a second slot wall 1512, a third slot wall 1513 and a fourth slot wall 1514. The first slot wall 1511 and the second slot wall 1512 are arranged opposite to each other along the first direction L1. The third slot wall 1513 and the fourth slot wall 1514 are located between the first slot wall 1511 and the second slot wall 1512 and are both connected to the first slot wall 1511 and the second slot wall 1512. The third slot wall 1513 is adjacent to the first area 1112 relative to the fourth slot wall 1514, and the fourth slot wall 1514 is adjacent to the third area 1116 relative to the third slot wall 1513.

[0131] When the support member 20 is located at the first position, the first protrusion 212 is close to the third groove wall 1513 (see Fig.14 ); When the support member 20 is transformed from the first position to the second position, the first protrusion 212 gradually approaches the fourth groove wall 1514 (see Fig.16 ); When the support member 20 is located at the second position, the first protrusion 212 can abut against the fourth groove wall 1514 (see Fig.18 ), at this time, the surface of the support member 20 abuts against the decorative member 30, which is equivalent to that the fourth groove wall 1514 and the decorative member 30 can both play a stopping role.

[0132] Please combine Fig.12 , Fig.19 and Fig. 20The housing 10 includes a first side 17 and a second side 19 connected to each other. The first side 17 extends along the first direction L1, and the second side 19 extends along the second direction L2. The first side 17 corresponds to the short side of the terminal device 200, and the second side 19 corresponds to the long side of the terminal device 200. The second groove wall 1512 is close to the first side 17 relative to the first groove wall 1511, and the fourth groove wall 1514 is close to the second side 19 relative to the third groove wall 1513. When the support member 20 is located at the second position, the support member 20 can be supported on the bearing surface S together with the first side 17 to realize the support function of the bracket assembly 100; or the support member 20 and the second side 19 can be supported on the bearing surface S together to realize the support function of the bracket assembly 100.

[0133] When the support member 20 and the first side 17 (ie, the short side of the housing 10) are supported on the bearing surface S together (ie, the bracket assembly 100 is Figure 1 The terminal device 200 is supported on the bearing surface S in the state shown in the figure. The pressing force acts on the support member 20. The first protrusion 212 of the support member 20 can abut against the first groove wall 1511 of the slot 151, which can increase the difficulty of the fixed shaft 15 to be separated from the opening 271 of the support member 20, thereby increasing the pressure resistance of the bracket assembly 100. When the support member 20 and the second side 19 (i.e., the long side of the housing 10) are jointly supported on the bearing surface S (i.e., the bracket assembly 100 is as shown in the figure), the terminal device 200 is subjected to the pressing force acting on the support member 20. The first protrusion 212 of the support member 20 can abut against the first groove wall 1511 of the slot 151, which can increase the difficulty of the fixed shaft 15 to be separated from the opening 271 of the support member 20, thereby increasing the pressure resistance of the bracket assembly 100. Figure 2 In the state shown, the terminal device 200 is supported on the bearing surface S, and the pressing force acts on the support member 20. The first protrusion 212 of the support member 20 can abut against the third groove wall 1513 of the slot 151, which can increase the difficulty of the fixed shaft 15 to be separated from the opening 271 of the support member 20, thereby increasing the pressure resistance of the bracket assembly 100. That is, when the bracket assembly 100 realizes the supporting function, the first protrusion 212 can abut against the groove wall of the slot 151 away from the bearing surface S, thereby increasing the difficulty of the fixed shaft 15 to be separated from the opening 271 of the support member 20.

[0134] The number of the first protrusions 212 and the number of the slots 151 can be set according to actual needs. In the present embodiment, the number of the slots 151 and the number of the first protrusions 212 are both one, the first protrusion 212 is located in the middle area of ​​the first holding portion along the first direction L1, and the slot 151 is located in the middle area of ​​the fixed axis 15 along the first direction L1; in other embodiments, the number of the first protrusions 212 and the slots 151 can be multiple.

[0135] The recessed depth of the slot 151 is matched with the protruding thickness of the first protrusion 212 . In some embodiments, the protruding thickness of the first protrusion 212 may be 3 mm-7 mm. The recessed depth of the slot 151 cannot be too deep to prevent the strength of the fixed shaft 15 from being weakened.

[0136] The width of the slot 151 along the first direction L1 matches the width of the first protrusion 212 along the first direction L1. There may be gaps between the first protrusion 212 and the first slot wall 1511 and the second slot wall 1512 to reduce the resistance of the support member 20 during the rotation process. The gap between the first protrusion 212 and the first slot wall 1511 and the second slot wall 1512 should not be too large, and only an assembly space is required so that the first protrusion 212 can abut against the first slot wall 1511.

[0137] Please refer again Fig.11 The second clamping portion 23 includes a second protrusion 231, which is located at the end of the second clamping portion 23 away from the support portion 25, and extends toward the end of the first clamping portion 21 away from the support portion 25. The second protrusion 231 is used to reduce the size of the opening 271 (i.e., the minimum distance between the first clamping portion 21 and the second clamping portion 23 away from one end of the support portion 25), which is conducive to increasing the difficulty of the fixed shaft 15 to be separated from the opening 271; the second protrusion 231 can also increase the covering area of ​​the second clamping portion 23 covering the fixed shaft 15, further increasing the difficulty of the fixed shaft 15 to be separated from the opening 271, and thus can increase the pressure resistance strength of the bracket assembly 100.

[0138] Please refer again Fig.11 The second clamping portion 23 is provided with a first groove 233, which is located between the second protrusion 231 and the support portion 25, and is adjacent to the support portion 25. The first groove 233 is formed by the second clamping portion 23 being recessed toward the surface of the first clamping portion 21. The first groove 233 is used to release local stress. Specifically, when the support member 20 is assembled on the fixed shaft 15, the first clamping portion 21 and the second clamping portion 23 will produce a certain deformation, and the support member 20 and the fixed shaft 15 are interference-fitted, which is used to increase the difficulty of the support member 20 being separated from the fixed shaft 15 after the support member 20 is assembled on the fixed shaft 15. Since the second clamping portion 23 is located on the outside, the deformation of the second clamping portion 23 should be as small as possible to prevent the deformation from being too large and affecting the appearance. With the provision of the first groove 233, the second clamping portion 23 can release local stress in the area of ​​the first groove 233 to reduce the deformation of the second clamping portion 23, thereby reducing the influence of the deformation of the second clamping portion 23 on the appearance of the bracket assembly 100.

[0139] Please refer again Fig.11 The second clamping portion 23 may also be provided with a second groove 235, the second groove 235 is located between the first groove 233 and the second protrusion 231, the second groove 235 is adjacent to the second protrusion 231 and is spaced apart from the first groove 233, and the second groove 235 is formed by the second clamping portion 23 being recessed toward the surface of the first clamping portion 21. The provision of the second groove 235 is equivalent to increasing the size of the support member 20 adjacent to the opening 271, which is beneficial to the installation of the support member 20.

[0140] Please refer again Fig.11 The support member 20 may further include a reinforcing rib 29, which connects the ends of the first clamping portion 21 and the second clamping portion 23 away from the opening 271. After the bracket assembly 100 is assembled on the terminal device 200, the support member 20 will switch between the first position and the second position for many times, and the first clamping portion 21 and the second clamping portion 23 will be deformed for many times. The reinforcing rib 29 can increase the fatigue strength of the first clamping portion 21 and the second clamping portion 23, thereby increasing the service life of the support member 20.

[0141] The above implementation modes are only used to illustrate the technical solutions of the present application and are not intended to limit the present application. Although the present application has been described in detail with reference to the above preferred implementation modes, a person skilled in the art should understand that the technical solutions of the present application may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present application.
