It should be understood that the terms used in this way are interchangeable where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or are inherent to these processes, methods, products or devices.

[0031] It should also be noted that the division of multiple embodiments in the present invention is only for the convenience of description and should not constitute a special limitation. The features in various embodiments can be combined and referenced to each other without contradiction.

[0032] Reference Figure 1 , the present invention provides a rotating shaft structure 10, which can be applied to the bracket, so refer to Figure 4 The present invention also provides a bracket, which includes a rotating shaft structure 10, a bracket base 30 and a support member 20 (refer to Figure 4 In the bracket provided in this embodiment, the hinge structure 10 is respectively connected to the bracket base 30 and the support member 20, so that the support member 20 can be rotatably connected to the bracket base 30 via the hinge structure 10 to achieve adjustment of different opening angles (or support angles). Of course, in other embodiments, the hinge structure 10 can also be applied to accessories similar to brackets in which one component rotates relative to another component to achieve different opening angle requirements.

[0033] In one embodiment of the present invention, the shaft structure 10 includes: a shaft sleeve 11, a first fixing portion 12 and a second fixing portion 13. The shaft sleeve 11 has a first direction ( Figure 1 The first fixing portion 12 is connected to one side of the sleeve 11 and includes at least two sub-fixing portions 1201 spaced apart along the first direction. Figure 1 and Figure 2 The first fixing portion 12 includes a connecting surface 122 and a second fixing surface 124 along the second direction ( Figure 1 The second fixing portion 13 is connected to the sleeve 11 and is located between two adjacent sub-fixing portions 1201. The second fixing portion 13 extends toward the connecting surface 122 away from the top surface 121 and protrudes from the connecting surface 122.

[0034] Hereinafter, the structure and principle of the rotating shaft structure 10 will be specifically described by taking a structure in a bracket provided in an embodiment of the present invention as an example. The rotating shaft structure 10 further includes a rotating shaft 15 (refer to Figure 4 ), the shaft sleeve 11 is in a rolled shape and can be formed by curling one end of a metal sheet to form a shaft hole 111. The rotating shaft 15 is inserted into the shaft hole 111 and can rotate in the shaft hole 111. When the rotating shaft structure 10 is used, the support member 20 can be connected to the rotating shaft 15, so that the support member 20 can rotate with the rotation of the rotating shaft 15 to achieve opening and closing or adjustment of the support angle. The first fixing part 12 is, for example, a riveted structure, and each sub-fixing part 1201 is provided with a rivet hole. When fixing the rotating shaft structure 10 to the bracket base 30, the first fixing part 12 can be riveted to the bracket base 30 by riveting. The connecting surface 122 is the surface of the first fixing part 12 facing the bracket base 30, and the top surface 121 is the surface of the first fixing part 12 facing away from the bracket base 30. The second fixing portion 13 extends toward the connection surface 122 in a direction away from the top surface 121. From the perspective of installation on the bracket base 30, the second fixing portion 13 extends in a direction gradually approaching the bracket base 30. Since the second fixing portion 13 protrudes from the connection surface 122, it can be inserted into the bracket base 30. The second fixing portion 13 can be formed by bending the middle portion of the other end of the metal sheet forming the shaft sleeve 11 toward one side, with the unbent portion of the other end serving as the first fixing portion 12.

[0035] In some embodiments, reference Figure 5 and Figure 6 The corresponding bracket base 30 is provided with a fixing groove 31 and a connecting portion 32 located at opposite ends of the fixing groove 31. When the first fixing portion 12 is provided with a rivet hole, the connecting portion 32 is configured as a rivet column. The number of the fixing grooves 31 corresponds to the number of the second fixing portions 13, and the number of the connecting portions 32 corresponds to the number of the sub-fixing portions 1201. For example Figure 1 As shown in FIG, there are two sub-fixing parts 1201, each of which is provided with two rivet holes, and there is one second fixing part 13. Figure 6 , there is one fixing groove 31 and two connecting portions 32, each of which has two riveted posts. When the hinge structure 10 is connected to the bracket base 30, the first fixing portion 12 is riveted to the connecting portion 32, and the second fixing portion 13 is inserted into the fixing groove 31.

[0036] Through the above settings, during the rotation of the bracket relative to the bracket base 30 by the rotating shaft 15, the forces at the connection between the rotating shaft structure 10 and the bracket base 30 are respectively shared by the first fixing portion 12 and the second fixing portion 13, which can reduce the force received by the first fixing portion 12, and further prevent the problem of separation between the connection surface 122 and the bracket base 30 due to excessive force, and can improve the connection strength between the rotating shaft structure 10 and the bracket base 30.

[0037] In some embodiments, the second fixing portion 13 and the adjacent sub-fixing portion 1201 are arranged at intervals. Refer to Figure 1 and Figure 2 , both ends of the second fixing portion 13 in the first direction are arranged at intervals from the two sub-fixing portions 1201 respectively. For example, the second fixing portion 13 and the sub-fixing portions 1201 can be separated by cutting between the second fixing portion 13 and the two sub-fixing portions 1201, which can reduce the mutual influence between the first fixing portion 12 and the second fixing portion 13 and make the force better.

[0038] In some embodiments, the included angle range between the extending direction of the second fixing portion 13 and the connection surface 122 is 80° to 100°, preferably 90°. This makes the first fixing portion 12 and the second fixing portion 13 be arranged nearly perpendicular to each other, and the force can be distributed to two mutually perpendicular directions, making the force sharing effect better and enabling a more stable connection with the bracket base 30.

[0039] In some embodiments, the length of the second fixing portion 13 in the first direction is less than the length of the shaft sleeve 11 in the first direction and greater than or equal to one-third of the length of the shaft sleeve 11 in the first direction. Refer to Figure 3 , that is, L1 / 3 ≤ L3 < L1. This can ensure that the length of the second fixing portion 13 reaches a better length for sharing the force, prevent the effect of sharing the force from being not obvious due to the too short second fixing portion 13, and can also prevent the second fixing portion 13 from being too long, ensuring that the first fixing portion 12 remains the main force-bearing part and making the connection more stable.

[0040] In some embodiments, the difference between the length of the second fixing portion 13 in the first direction and the length of the shaft sleeve 11 in the first direction is greater than or equal to four times the thickness of the first fixing portion 12 in the second direction. Refer to Figure 3 , that is, L1 - L3 ≥ 4H1. Within this range, the force that the first fixing portion 12 can bear reaches the maximum, which can improve the connection strength of the first fixing portion and further improve the connection strength of the entire rotating shaft structure 10.

[0041] In some embodiments, the length by which the second fixing portion 13 protrudes from the connection surface 122 is greater than or equal to twice the thickness of the first fixing portion 12 in the second direction (that is, the distance between the connection surface 122 and the top surface 121). Refer to Figure 3 , that is, H2≥2H1, so that the second fixing portion 13 reaches a suitable insertion depth, improving the effect of the second fixing portion 13 sharing the force and enhancing the connection stability.

[0042] In some embodiments, the first fixing portion 12 includes two edges opposite to each other along the first direction, and the minimum distance between the two edges and the sleeve 11 along the first direction is greater than or equal to half the length of the sleeve 11 along the first direction. Figure 3 As shown, the first direction is the horizontal direction, and the minimum distances between the two edges of the first fixing portion 12 and the sleeve 11 along the first direction are the horizontal distances between the left edge of the first fixing portion 12 and the left end of the sleeve 11 and the horizontal distances between the right edge of the first fixing portion 12 and the right end of the sleeve 11. Figure 3 , i.e., L4 ≥ L1 / 2. When the shaft structure 10 is symmetrically arranged, i.e., when the sleeve 11 is centered relative to the first fixing portion 12, the values ​​of L4 on both sides are equal and are half of the length L2 of the first fixing portion 12 along the first direction. This ensures that the first fixing portion 12 has an appropriate length and can better withstand force.

[0043] In some embodiments, the sleeve 11 is located on the side of the top surface 121 away from the connecting surface 122. Figure 3 In the orientation shown, the sleeve 11 is located above the first fixing portion 12 and the second fixing portion 13. Compared with the horizontal arrangement of the sleeve 11 and the first fixing portion 12, the width of the rotating shaft structure 10 along the horizontal direction can be reduced, and the area occupied by the rotating shaft structure 10 in the bracket can be reduced, which facilitates the realization of an invisible rotating shaft structure.

[0044] In some embodiments, reference Figure 1 and Figure 2 The shaft structure 10 further includes a bending portion 14 , which is connected between the shaft sleeve 11 and the first fixing portion 12 . The shaft sleeve 11 , the bending portion 14 and the first fixing portion 12 together enclose an avoidance space 141 . Figure 7 A partial cross-sectional view of the support member 20 in the bracket in an open state is shown. Figure 7 As shown in the figure, the avoidance space 141 provides a storage position for the edge of the support member 20, so that a part of the edge of the support member 20 can extend into the avoidance space 141, which can avoid interference between the edge and the rotating shaft structure 10 when the support member 20 is rotated to a certain angle, so that the support member 20 can reach an opening angle close to 180°, which can adapt to support requirements at more angles.

[0045] The present invention also provides an electronic device accessory, comprising a housing 40 and the bracket provided in the above embodiment, wherein the bracket base 30 is connected to the housing 40 or serves as a component of the housing 40. Figure 8, the electronic device accessory is, for example, a protective case with a bracket. In this case, the housing 40 is the shell of the protective case. The housing 40, for example, includes a back panel and side frames. The back panel and side frames together enclose a storage space. When using the protective case, the housing 40 is placed on the electronic device, and the electronic device is located in the storage space. The bracket can be set on the back panel, wherein the bracket base 30 can be a part of the back panel, or it can be an independent component fixed to the back panel by riveting, bonding, clamping, magnetism, etc. Of course, in some embodiments, the electronic device accessory can also be an accessory such as a wireless charger, in which case the housing 40 is the outer shell of the wireless charger. This embodiment is not limited to the above example.

[0046] exist Figure 8 In the illustrated embodiment, a camera avoidance hole 41 is provided on the housing 40, the bracket base 30 is embedded in the camera avoidance hole 41, and the support member 20 is an annular structure. The bracket base 30 may be an annular structure, or may be provided only at a portion of the edge corresponding to the camera avoidance hole 41. When the housing 40 is mounted on the electronic device, the camera on the electronic device may extend from the camera avoidance hole 41 (or be exposed), and the support member 20 is an annular structure, which can achieve the supporting function while avoiding blocking the camera, so that the normal operation of the camera is not affected when the bracket is not opened. The electronic device accessory provided in this embodiment applies the aforementioned bracket and the aforementioned hinge structure 10, and has the same effects as the aforementioned bracket and hinge structure 10, which will not be described in detail here.
