[0004] In some embodiments, the second bracket includes a first surface with a first positioning groove, and the support frame has a positioning block; the folding bracket is in a first unfolded state, and the positioning block is positioned in the first positioning groove. The design of the positioning block being positioned in the first positioning groove makes it difficult for the support frame to detach from the second bracket, which helps to improve the stability of the folding bracket.

[0005] In some embodiments, the second bracket further includes a second surface opposite to the first surface; the second surface is provided with a second positioning groove, and the positioning block is positioned in the second positioning groove when the folding bracket is in a second unfolded state. The design of the positioning block being positioned in the second positioning groove makes it difficult for the support frame to detach from the second bracket, which helps to improve the stability of the folding bracket.

[0006] In some embodiments, there are multiple first positioning slots, which are arranged at intervals along a direction perpendicular to the first rotation axis between the first bracket and the second bracket; the positioning blocks are sequentially positioned from the first positioning slots near the first rotation axis to the first positioning slots away from the first rotation axis, and the included angle between the first bracket and the second bracket gradually decreases; there are also multiple second positioning slots, which are arranged at intervals along a direction perpendicular to the first rotation axis; the positioning blocks are sequentially positioned from the second positioning slots near the first rotation axis to the second positioning slots away from the first rotation axis, and the included angle between the first bracket and the second bracket gradually decreases.

[0007] In this embodiment, by setting multiple first positioning slots and multiple second positioning slots, the included angle between the first bracket and the second bracket is different when the positioning block is positioned in different first positioning slots and different second positioning slots.

[0008] In some embodiments, the second bracket is provided with a hand-held hole located at one end of the second bracket away from the first rotation axis between the first and second brackets. The wall of the hand-held hole is provided with multiple finger grooves, which are spaced apart along the axial direction of the first rotation axis.

[0010] In some embodiments, the folding bracket further includes a third bracket, the second bracket having a third clearance groove, one end of the third bracket being rotatably connected to the second bracket, and the third bracket being accommodated within the third clearance groove; the folding bracket also has a third unfolded state, in which the second bracket is located on one side of the first bracket, and a support frame is supported between the first and second brackets; the third bracket is located on the side of the second bracket facing away from the support frame, and the third bracket is spaced apart from the first bracket. By providing the third bracket, when the electronic device is placed on the third bracket, the height of the electronic device is higher, and the user can adjust the height of the electronic device according to their needs.

[0011] In some embodiments, the second bracket is provided with a cable passage hole, and the folding bracket is in a third unfolded state. The cable passage hole is located between the first and third brackets. By providing a cable passage hole, when the electronic device is charging, the charging cable can be placed on the side of the second bracket facing the support frame. The charging part of the charging cable passes through the cable passage hole and connects to the electronic device, avoiding the problem of the charging cable being placed in front of the user and affecting the appearance, thus improving the user experience.

[0012] In some embodiments, the third bracket is provided with a second abutment, and the folding bracket is in a third unfolded state. The second abutment is away from the first bracket and spaced apart from the second bracket. By providing the second abutment, the second abutment can limit the electronic device and prevent it from falling off the third bracket.

[0013] In some embodiments, the second bracket is provided with a limiting part, which is located within the third clearance groove; the folding bracket is in the third unfolded state, with one end of the third bracket located within the third clearance groove and abutting against the limiting part. By providing the limiting part, the limiting part can limit the third bracket, so that the folding bracket can be stably maintained in the third unfolded state, which is beneficial to improving the stability of the folding bracket.

[0014] In this application, the folding stand has a first unfolded state and a second unfolded state. Users can set the state of the folding stand according to the type of electronic device. For example, when the electronic device is a tablet, the folding stand is set to the first unfolded state; when the electronic device is a laptop, the folding stand is set to the second unfolded state.

[0028] Please refer to Figure 1 , Figure 2 and Figure 3 This embodiment provides a folding bracket 100, which includes a first bracket 10, a second bracket 20, a support frame 30, a first rotating shaft 40 and a second rotating shaft 50. The first bracket 10 has a first clearance groove 11 and a second clearance groove 12, and the first clearance groove 11 communicates with the second clearance groove 12. Figure 2 The dotted line in the diagram represents the boundary between the first clearance groove 11 and the second clearance groove 12. One end of the second bracket 20 is rotatably connected to the first bracket 10 via the first rotating shaft 40, and the second bracket 20 can be accommodated in the first clearance groove 11. One end of the support frame 30 is rotatably connected to the first bracket 10 via the second rotating shaft 50, and the support frame 30 can be accommodated in the second clearance groove 12. The folding bracket 100 has a stowed state, a first unfolded state, and a second unfolded state. When the folding bracket 100 is in the stowed state, the second bracket and the support frame 30 are respectively accommodated in the first clearance groove 11 and the second clearance groove 12.

[0029] Please refer to Figure 3 , Figure 4 and Figure 5In the first unfolded state, the folding bracket 100 is located on one side of the first bracket 10, and the support frame 30 is supported between the first bracket 10 and the second bracket 20; in the second unfolded state, the folding bracket 100 is located on the opposite side of the first bracket 10, and the support frame 30 is supported between the first bracket 10 and the second bracket 20.

[0030] Please refer to Figure 2 In some embodiments, the first bracket 10 is rectangular in shape and includes a connecting portion 13 and a first abutting portion 14 located at one end of the connecting portion 13. The first abutting portion 14 is inclined relative to the connecting portion 13, and an angle is formed between the first abutting portion 14 and the connecting portion 13. A first clearance groove 11 and a second clearance groove 12 are provided on the connecting portion 13, and the first clearance groove 11 and the second clearance groove 12 pass through the connecting portion 13 along the Z-axis direction. The connecting portion 13 is provided with two first rotating holes 131 and two second rotating holes 132. The two first rotating holes 131 are provided on the groove sidewall of the first clearance groove 11 and are facing each other along the Y-axis direction. The two second rotating holes 132 are provided on the groove sidewall of the second clearance groove 12 and are facing each other along the Y-axis direction. Two first rotating holes 131 and two second rotating holes 132 are arranged at intervals along the X-axis direction. The axis of the first rotating hole 131 and the axis of the second rotating hole 132 both extend along the Y-axis direction. The axis of the first rotating hole 131 is parallel to the axis of the second rotating hole 132.

[0031] Please refer to Figure 2 and Figure 3 In some embodiments, the second bracket 20 is in the shape of a rectangular plate and includes a first surface 21 and a second surface 22 facing away from each other. The first surface 21 is provided with a plurality of first positioning grooves 211, which are located at the end of the second bracket 20 away from the connection between the first bracket 10 and the second bracket 20. In this embodiment, the first surface 21 is provided with two rows of first positioning grooves 211 spaced apart along the Y-axis direction, wherein the plurality of first positioning grooves 211 in each row are spaced apart along the X-axis direction, and the X-axis direction is perpendicular to the axial direction of the first rotating hole 131.

[0032] The second surface 22 is provided with a plurality of second positioning grooves 221, and the plurality of first positioning grooves 211 are closer to the connection between the first bracket 10 and the second bracket 20 than the second positioning grooves 221. In this embodiment, the second surface 22 is provided with two rows of second positioning grooves 221 arranged at intervals along the Y-axis direction, wherein the plurality of second positioning grooves 221 in each row of second positioning grooves 221 are arranged at intervals along the X-axis direction.

[0033] In some embodiments, the support frame 30 is U-shaped and includes a first segment 31, a second segment 32, a third segment 33, and positioning blocks 34. The first segment 31 and the second segment 32 are spaced apart along the Y-axis. The opposite ends of the third segment 33 are fixedly connected to one end of the first segment 31 and one end of the second segment 32, respectively. The positioning blocks 34 are fixedly connected to the surface of the third segment 33 facing away from the first segment 31 and the second segment 32. In this embodiment, there are two positioning blocks 34, which are spaced apart along the Y-axis.

[0034] In this embodiment, the second bracket 20 is rotatably connected to the connecting part 13. Specifically, a first rotating shaft 40 passes through the second bracket 20, with its opposite ends protruding from opposite sides of the second bracket 20 along the Y-axis. The opposite ends of the first rotating shaft 40 are rotatably connected to the two first rotating holes 131 of the connecting part 13. The support frame 30 is rotatably connected to the connecting part 13. Specifically, there are two second rotating shafts 50. The end of the first segment 31 furthest from the third segment 33 is fixedly connected to one end of one of the second rotating shafts 50, and the other end of this second rotating shaft 50 is rotatably connected to one of the second rotating holes 132. The end of the second segment 32 furthest from the third segment 33 is fixedly connected to one end of the other second rotating shaft 50, and the other end of this second rotating shaft 50 is rotatably connected to the other second rotating hole 132. The second rotating shaft 50 between the support frame 30 and the connecting part 13 is parallel to the first rotating shaft 40 between the second bracket 20 and the connecting part 13, and the first rotating shaft 40 is closer to the first abutment 14 than the second rotating shaft 50.

[0035] Among them, such as Figure 1 When the folding bracket 100 is in the stowed state, the second bracket 20 is housed within the first clearance groove 11. The first surface 21 and the second surface 22 of the second bracket 20 are flush with the two opposing surfaces of the connecting portion 13 of the first bracket 10 along the Z-axis direction, respectively. A U-shaped groove is formed between the second bracket 20 and the first bracket 10, which is the second clearance groove 12. The support frame 30 is housed within the second clearance groove 12, and the two opposing surfaces of the support frame 30 along the Z-axis direction are flush with the two opposing surfaces of the connecting portion 13 along the Z-axis direction, respectively.

[0036] The folding bracket 100 can be switched from a stowed state to a first unfolded state and a second unfolded state, such as... Figure 3 and Figure 4When the folding bracket 100 switches from the folded state to the first unfolded state, the second bracket 20 rotates to one side of the connecting portion 13 of the first bracket 10, forming an angle between the second bracket 20 and the connecting portion 13 of the first bracket 10, and there is a gap between the second bracket 20 and the first abutment portion 14 of the first bracket 10. The support frame 30 rotates between the first bracket 10 and the second bracket 20, with the end of the support frame 30 away from the first bracket 10 supported by the second bracket 20. One positioning block 34 is positioned in one of the first positioning grooves 211 in one row of first positioning grooves 211, and the other positioning block 34 is positioned in one of the first positioning grooves 211 in another row of first positioning grooves 211, so as to achieve locking between the first bracket 10 and the second bracket 20. The positioning blocks 34 are positioned in the first positioning grooves 211, making it difficult for the support frame 30 to detach from the second bracket 20, which helps to improve the stability of the folding bracket 100.

[0037] When the folding bracket 100 is in its first unfolded state, it is used to place a first device, which includes, but is not limited to, a smartphone, tablet, or other handheld electronic device. For example, the connecting part 13 of the first bracket 10 is placed on a table, the bottom of the first device is supported by the first stop part 14, the first stop part 14 limits the first device, and the back of the first device is supported by the second bracket 20 on the side opposite to the support frame 30.

[0038] If a user needs to adjust the placement angle of the first device, they can do so by positioning the positioning block 34 of the support frame 30 in different first positioning slots 211, thereby changing the angle between the first bracket 10 and the second bracket 20, and thus altering the placement angle of the first device. Specifically, the positioning block 34 is positioned sequentially from the first positioning slot 211 closest to the first rotating shaft 40 to the first positioning slot 211 furthest from the first rotating shaft 40, with the angle between the first bracket 10 and the second bracket 20 gradually decreasing. When the positioning block 34 is positioned in the first positioning slot 211 furthest from the first rotating shaft 40, the angle between the first bracket 10 and the second bracket 20 is the smallest. When the positioning block 34 is positioned in the first positioning slot 211 closest to the first rotating shaft 40, the angle between the first bracket 10 and the second bracket 20 is the largest. Users can adjust the angle between the first bracket 10 and the second bracket 20 according to the usage scenario, thereby changing the placement angle of the first device and improving the user experience.

[0039] like Figure 5As shown, when the folding bracket 100 switches from the retracted state to the second unfolded state, the second bracket 20 rotates to the opposite side of the connecting portion 13 of the first bracket 10, forming an angle between the second bracket 20 and the connecting portion 13 of the first bracket 10. The support frame 30 rotates to the space between the connecting portion 13 of the first bracket 10 and the second bracket 20, with one end of the support frame 30 away from the connecting portion 13 of the first bracket 10 supported by the second bracket 20. One positioning block 34 is positioned in one of the second positioning grooves 221 in one row of second positioning grooves 221, and the other positioning block 34 is positioned in one of the second positioning grooves 221 in another row of second positioning grooves 221, thereby locking the first bracket 10 and the second bracket 20 together. The positioning blocks 34 are positioned in the second positioning grooves 221, making it difficult for the support frame 30 to detach from the second bracket 20, which helps to improve the stability of the folding bracket 100.

[0040] When the folding stand 100 is in its second unfolded state, it is used to place a second device, which may include, but is not limited to, larger electronic devices such as tablets and laptops. Specifically, the second bracket 20 is placed on a desktop, the bottom of the second device is supported by the first stop portion 14 of the first bracket 10, and the back of the second device is supported by the connecting portion 13 of the first bracket 10.

[0041] If a user needs to adjust the placement angle of the second device, they can do so by positioning the positioning block 34 of the support frame 30 in different second positioning slots 221, thereby changing the angle between the first bracket 10 and the second bracket 20, and thus altering the placement angle of the second device. Specifically, the positioning block 34 is positioned sequentially from the second positioning slot 221 closest to the first rotation axis 40 to the second positioning slot 221 furthest from the first rotation axis 40, with the angle between the first bracket 10 and the second bracket 20 gradually decreasing. When the positioning block 34 is positioned in the second positioning slot 221 furthest from the first rotation axis 40, the angle between the first bracket 10 and the second bracket 20 is the smallest. When the positioning block 34 is positioned in the second positioning slot 221 closest to the first rotation axis 40, the angle between the first bracket 10 and the second bracket 20 is the largest. Users can adjust the angle between the first bracket 10 and the second bracket 20 according to the usage scenario, thereby adjusting the placement angle of the second device, which improves the user experience.

[0042] In this embodiment, the folding stand 100 has a first unfolded state and a second unfolded state. Users can set the state of the folding stand 100 according to the type of electronic device. For example, when the electronic device is a tablet, the folding stand 100 is set to the first unfolded state; when the electronic device is a laptop, the electronic device is set to the second unfolded state. The folding stand 100 has more diverse usage scenarios; one folding stand 100 can be used to hold different electronic devices, which helps improve the user experience. Furthermore, the folding stand 100 can switch between the first unfolded state and the second unfolded state simply by changing the relative positions of the first bracket 10, the second bracket 20, and the support frame 30, without requiring additional components, resulting in a simple structure.

[0043] In addition, by setting the first clearance groove 11 and the second clearance groove 12, when the folding bracket 100 is in the storage state, the second bracket 20 and the support frame 30 are respectively accommodated in the first clearance groove 11 and the second clearance groove 12, resulting in a compact structure, smaller product size, and easy portability.

[0044] Please refer to Figure 1 and Figure 2 In some embodiments, the second bracket 20 is provided with a hand-held hole 23, which is located at one end of the second bracket 20 away from the first rotation axis 40 between the first bracket 10 and the second bracket 20. The hand-held hole 23 passes through the first surface 21 and the second surface 22 along the Z-axis. Multiple finger grooves 231 are provided in the hole wall of the hand-held hole 23 facing the first rotation axis 40, and these grooves are spaced apart axially along the first rotation axis 40 between the first bracket 10 and the second bracket 20. In this embodiment, when the folding bracket 100 is in the retracted state, the user can reach into the hand-held hole 23 to grasp the first bracket 10 and the second bracket 20 and pick up the folding bracket 100. By providing multiple finger grooves 231, when the user reaches into the hand-held hole 23, their fingers can be placed within the finger grooves 231, which is more ergonomic and makes it easier to grasp the folding bracket 100, thus improving the user experience.

[0045] Please refer to Figure 2 , Figure 6 and Figure 7In some embodiments, the folding bracket 100 further includes a third bracket 60 and a third rotating shaft 70. The second bracket 20 is also provided with a third clearance groove 24, which is spaced apart from the handheld hole 23 along the X-axis direction. The third clearance groove 24 is closer to the first rotating shaft 40 than the handheld hole 23. The third clearance groove 24 is rectangular and passes through the first surface 21 and the second surface 22 along the thickness direction of the second bracket 20. The second bracket 20 is provided with two third rotating holes 241, which are disposed on the sidewall of the third clearance groove 24 and are directly opposite each other along the Y-axis direction. The axes of the two third rotating holes 241 are parallel to the axis of the first rotating hole 131.

[0046] The third bracket 60 is U-shaped and includes a rotating part 61 and two support plates 62. The rotating part 61 is elongated and extends along the Y-axis. The two support plates 62 are fixedly connected to the rotating part 61 and are spaced apart along the Y-axis. Optionally, the third bracket 60 is provided with two second abutment parts 621. The two second abutment parts 621 are respectively disposed on one side of the two support plates 62 along the thickness direction, and both second abutment parts 621 are spaced apart from the rotating part 61.

[0047] In this embodiment, one end of the third bracket 60 is rotatably connected to the second bracket 20 via a third rotating shaft 70, and the third bracket 60 can be accommodated in the third clearance groove 24. Specifically, there are two third rotating shafts. One end of one third rotating shaft 70 passes through one end of the rotating part 61 along the Y-axis direction, and the other end of the third rotating shaft 70 is rotatably connected to one of the third rotating holes 241. One end of the other third rotating shaft 70 passes through the opposite end of the rotating part 61, and the other end of the third rotating shaft is rotatably connected to the other third rotating hole 241.

[0048] like Figure 4 , Figure 6 and Figure 7 The folding bracket 100 also has a third unfolded state. In this state, the second bracket 20 is located on one side of the first bracket 10, and the support frame 30 is supported between the first bracket 10 and the second bracket 20. The third bracket 60 is located on the side of the second bracket 20 away from the support frame 30, forming an angle with the second bracket 20. The third bracket 60 is spaced apart from the first bracket 10, and the second abutment 621 is away from the first bracket 10 and spaced apart from the second bracket 20. Understandably, when the folding bracket 100 is in the first unfolded state, the third bracket 60 rotates to the side of the second bracket 20 away from the support frame 30, thus switching the folding bracket 100 from the first unfolded state to the third unfolded state.

[0049] In this embodiment, when the folding bracket 100 is in its third unfolded state, it is used to place the first device. The bottom of the first device is supported by the tray 62 of the third bracket 60, and the back of the first device is supported by the second bracket 20. Understandably, the design of the third bracket 60 allows users to increase the placement height of the first device, thus improving the user experience. The design of the second stop 621 limits the first device, preventing it from falling off the third bracket 60.

[0050] Please refer to Figure 6 In some embodiments, the second bracket 20 is provided with a cable passage hole 25. The cable passage hole 25, the third clearance groove 24, and the handheld hole 23 are arranged sequentially at intervals along the X-axis direction. The cable passage hole 25 is closer to the first rotation axis 40 than the third clearance groove 24. The cable passage hole 25 passes through the first surface 21 and the second surface 22 along the thickness direction of the second bracket 20. When the folding bracket 100 is in the third unfolded state, the cable passage hole 25 is located between the first bracket 10 and the third bracket 60. When the first device is placed on the third bracket 60, the charging port of the first device faces the cable passage hole 25 at the bottom. When the first device is charging, the charging cable is first placed on the side of the second bracket 20 facing the support frame 30, and the charging part of the charging cable passes through the cable passage hole 25 and then connects to the first device. In this embodiment, by providing the cable passage hole 25, when the first device is charging, the charging cable can be placed on the side of the second bracket 20 facing the support frame 30, avoiding the problem of the charging cable being placed in front of the user and affecting the appearance, which is beneficial to improving the user experience.

[0051] Please refer to Figures 8-11 In some embodiments, the second bracket 20 is provided with a limiting part 26, which is located within the third clearance groove 24, away from the wire hole 25, and between the two third rotating holes 241. The third bracket 60 is provided with a limiting groove 611, which is disposed in the rotating part 61 of the third bracket 60, away from the two trays 62.

[0052] When the folding bracket 100 is in its first unfolded state, the third bracket 60 is housed within the third clearance groove 24, and the limiting part 26 is housed within the limiting groove 611. The bottom surface of the limiting groove 611 is located on the side of the limiting part 26 away from the first bracket 10, and the bottom surface of the limiting groove 611 is spaced apart from the limiting part 26. When the folding bracket 100 switches from the first unfolded state to the third unfolded state, one end of the third bracket 60 rotates to the side of the second bracket 20 away from the support frame 30, and the other end of the third bracket 60 is located within the third clearance groove 24 and abuts against the limiting part 26. Specifically, the two trays 62 rotate to the side of the second bracket 20 away from the support frame 30, the rotating part 61 is located within the third clearance groove 24, the rotating part 61 rotates around the axis of the first rotating shaft 40, and the bottom surface of the limiting groove 611 of the rotating part 61 rotates to the side of the limiting part 26 away from the support frame 30 and abuts against the limiting part 26. In this embodiment, by setting the limiting part 26, the limiting part 26 can limit the third bracket 60, so that the folding bracket 100 can be stably maintained in the third unfolded state, which is beneficial to improving the stability of the folding bracket 100.

[0053] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of this patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
