[0015] In one embodiment, the pivot connector includes an angular elastic member disposed between the bearing seat and the mounting member and abutting against the bearing seat and the mounting member respectively, so as to restrict the pivot connector in the clearance position.

[0016] In one embodiment, the angular elastic element is a torsion spring, which is sleeved on the second rotating shaft, and the two torsion arms of the torsion spring abut against the shaft seat and the mounting member, respectively.

[0020] In one embodiment, the support member includes a support body and a hinge. The hinge includes a roll and a connecting portion. The connecting portion is fixedly connected to the support body, and the roll is sleeved on the first rotating shaft. When the rotating shaft connector is received in the clearance position, the line connecting the first rotating shaft and the second rotating shaft is set at an angle to the connecting portion.

[0021] On the other hand, an embodiment of this application provides an electronic device accessory, including a bracket and a housing as described above.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0031] Please see Figure 1 One embodiment of this application provides an electronic device accessory, which includes a bracket 100 and a housing 200. The housing 200 is used to cover and protect an electronic device, such as a mobile phone or tablet computer. The bracket 100 is mounted on the housing 200 and can be stored relative to the housing 200. Figure 1 (as shown in the initial state) or open ( Figure 7 (as shown in the stop position) to support the electronic equipment in the housing 200.

[0032] Please refer to the following: Figure 2 The housing 200 includes a back plate 210 and a frame 220 surrounding the edge of the back plate 210. The back plate 210 and the frame 220 together form a space for housing electronic devices. A bracket 100 is mounted on the back of the back plate 210 to support the electronic devices. Corresponding to the bracket 100, the back of the back plate 210 has interconnected storage slots 211 and mounting slots 212. When the bracket 100 is installed in the mounting slot 212 and stored in the storage slot 211, the surface of the bracket 100 is flush with the surface of the back plate 210, making the back of the electronic device accessories a flat plane.

[0033] The bracket 100 further includes a support member 10, a rotating shaft connector 20, and a mounting member 30. The support member 10 is movably mounted on the mounting member 30 via the rotating shaft connector 20. The mounting member 30 is used to mount the bracket 100 onto the housing 200. Specifically, the support member 10 can rotate relative to the rotating shaft connector 20 about the main axis O1, so that the support member 10 can be housed in or unscrewed from the housing groove 211. The rotating shaft connector 20 can rotate relative to the mounting member 30 about the fixed axis O2, and the rotating shaft connector 20 can be housed in or ejected from the mounting member 30. The mounting member 30 is mounted in a mounting groove 212 opened on the back plate 210 of the housing 200 and can rotate about a Z-axis perpendicular to the surface of the back plate 210. The main axis O1 and the fixed axis O2 are parallel to each other and perpendicular to the Z-axis.

[0034] Please refer to further details. Figure 3 and Figure 4 The support member 10 includes a support body 11 and a hinge 12. The support body 11 is generally annular in shape, similar to the shape of the storage groove 211. The hinge 12 is connected to the inner side of one end edge of the support body 11, forming a hinge sleeve between the support member 10 and the rotating shaft connector 20, so that the support member 10 can be opened relative to the rotating shaft connector 20 or stored in the storage groove 211. The hinge 12 and the support body 11 can be fixedly connected by welding, gluing, riveting, etc., which is not limited here.

[0035] Specifically, the hinge 12 includes a rolled section 121 forming a hinge bushing and a connecting portion 122, which is fixedly connected to the support body 11. In the illustrated embodiment, the connecting portion 122 of the hinge 12 has a fixing hole, and is fixedly connected to the support body 11 by fasteners (such as screws, anchors, etc.).

[0036] To prevent the hinge 12 from being exposed, especially the rolled-up portion 121 of the hinge 12, which would affect the product's appearance and aesthetics, the support body 11 extends outwards from the hinge 12 mounting location with a covering portion 111. The edge of the covering portion 111 extends beyond the rolled-up portion 121, completely covering it from the outside. In the initial state, when the support member 10 is stored in the storage slot 211, the rolled-up portion 121 is not visible from the outside (the back of the housing 200), thus giving the product a cleaner external appearance and preventing dust from entering the rolled-up portion 121 and affecting its use.

[0037] Since the support member 10 is stored in the storage slot 211 when not in use and can be attracted to the magnet on the back of the electronic device via a magnet provided inside the support body 11, a handle position 112 is formed on the edge away from the hinge 12 to facilitate the removal of the support member 10 from the storage slot 211 when needed. Specifically, the handle position 112 forms a notch on the support body 11 for finger gripping, so that the support member 10 can be rotated out of the receiving slot 211 by applying force to the handle position 112.

[0038] The rotating shaft connector 20 serves as a rotatable connection between the support member 10 and the mounting member 30. It includes a first rotating shaft 21, a shaft seat 22, and a second rotating shaft 23. The first rotating shaft 21, which is positioned along the main axis O1, and the second rotating shaft 23, which is positioned along the fixed axis O2, are both mounted on the shaft seat 22. The first rotating shaft 21 rotatably connects the support member 10 and the shaft seat 22, and the second rotating shaft 23 rotatably connects the shaft seat 22 and the mounting member 30. The first rotating shaft 21 and the second rotating shaft 23 are parallel and spaced apart along the length of their respective shaft seats 22.

[0039] More specifically, the first pivot 21 passes through the rolled circle 121 of the hinge 12, forming a pivot for the support member 10 to rotate relative to the bearing seat 22 about the main axis O1. Two bearing seats 22 are provided, and the two ends of the first pivot 21 are fixedly connected to the bearing seats 22 on both sides, for example, by welding or gluing. In the illustrated embodiment, the first pivot 21 is a flat shaft, passing through the rolled circle 121 of the hinge 12 and achieving a damping fit effect with the rolled circle 121 through an interference fit. At least one first plane is cut out on the outer circumferential surface of the intermediate shaft section 211 of the first pivot 21, and correspondingly, the same number of second planes are also provided on the inner surface of the rolled circle 121. After the intermediate shaft section 211 of the first pivot 21 is inserted into the rolled circle 121, the first plane on the outer circumferential surface of the intermediate shaft section 211 faces the second plane on the inner surface of the rolled circle 121, thereby restricting rotation around the first pivot 21.

[0040] The two side bearing seats 22 are rotatably connected to the mounting member 30 via second rotating shafts 23, forming a rotating shaft in which the bearing seat 22 rotates relative to the mounting member 30 around a fixed axis O2. The fixing method between the second rotating shaft 23 and the mounting member 30 is not limited to welding, gluing, or other processes. In the illustrated embodiment, the second rotating shaft 23 is a pin that passes through the bearing seat 22 and connects to the mounting member 30.

[0041] Please refer to the following: Figure 5The first rotating shaft 21 includes an intermediate shaft section 211 and end shaft sections 212 at both ends along the axial direction. The intermediate shaft section 211 is thicker than the end shaft sections 212, thus forming a shoulder 213 at the connection between the intermediate shaft section 211 and the end shaft sections 212. This allows the end shaft sections 212 at both ends of the first rotating shaft 21 to be axially limited when inserted into the first rotating shaft fixing hole 221, preventing excessive insertion and protrusion from the outside of the bearing seat 22, thus avoiding interference with the mounting component 30. More specifically, each bearing seat 22 has a first rotating shaft fixing hole 221 and a second rotating shaft fixing hole 222, which are spaced apart along the length of the bearing seat 22. The shape of the first rotating shaft fixing hole 221 matches the shape of the non-rotating body at the end of the first rotating shaft 21, thereby constraining the end of the first rotating shaft 21 within the first rotating shaft fixing hole 221. The shape of the second rotating shaft fixing hole 222 matches that of the second rotating shaft 23, so that the second rotating shaft 23 can pass through the second rotating shaft fixing hole 222 and be connected to the mounting member 30.

[0042] The rotating shaft connector 20 also includes an angular elastic element, which is disposed between the shaft seat 22 and the mounting member 30 and abuts against both the shaft seat 22 and the mounting member 30 to provide an elastic preload torque. The angular elastic element provides a preload torque around the fixed axis O2 to press the shaft seat 22 into the mounting member 30. In this embodiment, the angular elastic element is a torsion spring 24, which is sleeved on the second rotating shaft 23 around the fixed axis O2, and its two torsion arms abut against the shaft seat 22 and the mounting member 30, respectively. The preload torque of the torsion spring 24 provides a force to press the shaft seat 22 into the mounting member 30, so that the shaft seat 22 remains housed in the mounting member 30 without any other external force. Please refer to [reference needed]. Figure 6 The second rotating shaft 23 includes a rod portion 231 and a cap portion 232 connected to one end of the rod portion 231 along the axial direction. The diameter of the cap portion 232 is larger than the diameter of the rod portion 231, so that the second rotating shaft 23 can be axially limited by the cap portion 232.

[0043] To facilitate the installation and storage of the torsion spring 24, the bearing seat 22 has an inward recess forming a receiving portion 223 on the outer side along the fixed axis O2, through which the second rotating shaft fixing hole 222 passes. When the torsion spring 24 is fitted onto the second rotating shaft fixing hole 222 of the pin structure, one end of the torsion spring 24 can be received in the receiving portion 223, and a torsion arm abuts against the side wall of the receiving portion 223.

[0044] Mounting component 30 includes a pivot base 31 and a retaining spring 32. The pivot base 31 is mounted along the Z-axis within a mounting groove 212 and can rotate around the Z-axis within the mounting groove 212. The retaining spring 32 is engaged between the bottom periphery of the pivot base 31 and the side wall of the mounting groove 212, allowing the overall bracket 100 and the back plate 210 to be constrained in linear motion along the Z-axis by the retaining spring 32, without restricting rotational motion around the Z-axis. Thus, the pivot base 31 can be mounted within the mounting groove 212 and rotate around the Z-axis within the mounting groove 212 to adjust the angle of the support component 10 in the Z-axis circumferential direction, thereby providing support for different usage methods of the electronic equipment.

[0045] Specifically, the end face of the pivot base 31 along the Z-axis is flush with the back surface of the back plate 210. The upper surface of the pivot base 31 is recessed along the Z-axis to form a connecting portion receiving groove 311. The connecting portion 122 of the hinge 12 can be received in the connecting portion receiving groove 311 or unscrewed from the connecting portion receiving groove 311. A clearance position is provided on the pivot base 31 corresponding to the pivot connector 20. The pivot connector 20 can be received in the clearance position or unscrewed from the clearance position. The clearance position is a groove formed by recessing the upper surface of the pivot base 31 of the mounting member 30 or a through groove penetrating the upper and lower surfaces of the mounting member. Thus, in the initial state, the support member 10 and the pivot connector 20 can be housed in the receiving groove 211 and the mounting groove 212, and do not protrude from the back surface of the back plate 210.

[0046] In the initial state, the connecting part 122 of the hinge 12 in the support member 10 is located on the connecting part receiving groove 311, the pivot connector 20 is embedded in the clearance position, and the bracket 100 is completely stored.

[0047] Corresponding to the structure of the rotating shaft connector 20, the clearance space on the rotating shaft base 31 includes a first rotating shaft clearance groove 312 and two shaft seat clearance grooves 313, with the two shaft seat clearance grooves 313 respectively connected to both ends of the first rotating shaft clearance groove 313. The first rotating shaft clearance groove 312 corresponds to the first rotating shaft 21 and communicates with the connecting portion receiving groove 311 to accommodate the first rotating shaft 21 and the rolled circle 121 sleeved on the first rotating shaft 21; the shaft seat clearance grooves 313 on both sides correspond to the shaft seats 22 on both sides of the first rotating shaft 21 to accommodate the two shaft seats 22 respectively. That is, the space formed by the first rotating shaft clearance groove 312 and the shaft seat clearance grooves 313 matches the shape formed by the first rotating shaft 21 and the shaft seats 22 at both ends. Two second shaft mounting holes 314 are provided on the shaft base 31. Each second shaft mounting hole 314 extends from the outer periphery of the shaft base 31 to the corresponding shaft seat clearance groove 313, so that each second shaft 23 can pass through the corresponding second shaft mounting hole 314 and connect to the second shaft fixing hole 222 on the corresponding shaft seat 22, thereby realizing the rotatable mounting of the shaft connector 20 onto the shaft base 31.

[0048] More specifically, corresponding to the assembled structure of the first rotating shaft 21 and the bearing seats 22 on both sides, the rotating shaft clearance groove 212 and the bearing seat clearance groove 313 extend in two mutually perpendicular directions. The rotating shaft clearance groove 212 communicates with the bearing seat clearance grooves 313 at both ends, forming a "U" shape together, as shown below. Figure 4 and Figure 6 As shown in the image.

[0049] Please see Figure 6 Corresponding to the structure of the second rotating shaft 23, the second rotating shaft mounting hole 314 is a stepped hole. The second rotating shaft mounting hole 314 includes a first hole portion 3141 and a second hole portion 3142 connected along the axial direction. The diameter of the second hole portion 3142 is larger than the diameter of the first hole portion 3141. The diameter of the cap portion 232 is smaller than the diameter of the second hole portion 3142 but larger than the diameter of the first hole portion 3141, so that the cap portion 232 forms an axial limit on the stepped surface of the stepped hole in the second hole portion 3142 after the rod portion 231 is inserted into the first hole portion 3141.

[0050] The pivot base 31 has a hollow portion 315 formed on the outer side of the bearing relief groove 313, corresponding to the receiving portion 223 on the bearing 22. The torsion spring 24 can be hidden in the hollow portion 315 of the pivot base 31 and the hollow portion 223 of the bearing 22, and the other torsion arm of the torsion spring 24 abuts against the side wall of the hollow portion 315. In this way, the torsion spring 24 is pre-compressed and torsionally installed along the fixed axis O2, and provides pre-compressing torque to the bearing 22, so that the pivot connector 20 is torsionally pressed into the relief position of the pivot base 31, and the pivot connector 20 can be lifted from the pivot base 31 to protrude from the back of the back plate 210 under the action of external force resisting the pre-compressing torque.

[0051] If the support member 10 is in the stop position (e.g.) Figure 7 When the support member 10 is opened to form a supported state, the torque applied to the rotating shaft connector 20 when supporting the electronic device is A, and the preload torque of the torsion spring 24 in the initial state is B. The preload torque B of the torsion spring 24 can be selected as follows: B = (0.6~0.9)A. If the preload torque B of the torsion spring 24 is too large, the force value will increase sharply when the rotating shaft connector 20 moves from the rotating shaft base 31 to the raised state, and the life of the torsion spring 24 will decrease significantly. If the preload torque B of the torsion spring 24 is too small, the force required to raise the rotating shaft connector 20 will be too small, making it feel loose when bent.

[0052] The bottom of the mounting component 30 is also provided with a positioning assembly for positioning the angle around the Z-axis, including a positioning seat 33, a positioning cam 34, a compression spring 35 and a cam guide shaft 36. The positioning seat 33 is in the shape of a ring around the Z-axis, and the positioning cam 34, the compression spring 35 and the cam guide shaft 36 are arranged radially along the positioning seat 33.

[0053] The inner ring of the positioning seat 33 is provided with inner positioning grooves 331 spaced around its circumference, and the outer ring of the positioning seat 33 is provided with outer positioning grooves 332 spaced around its circumference. The bottom of the mounting groove 212 is provided with limiting lugs 2121 spaced around its circumference. The lugs 2121 correspond one-to-one with the shape and position of the outer positioning grooves 332 of the positioning seat 33, thereby fixing the positioning seat 33 into the mounting groove 212 of the back plate 210.

[0054] A compression spring 35 is sleeved on a cam guide shaft 36, with one end abutting against the inner side of a positioning cam 34 along the radial direction of a positioning seat 33. The cam guide shaft 36 passes through the positioning cam 34 and the compression spring 35. A positioning part 341 protrudes from the side of the positioning cam 34 opposite to the compression spring 35, which engages with the inner positioning groove 331.

[0055] When the rotating shaft base 31 rotates around the Z-axis, the positioning assembly rotates along with the rotating shaft base 31. When it rotates to a specific position, the positioning part 341 of the positioning cam 34 extends into a certain inner positioning groove 331 of the positioning seat 33. At this time, if the external force is removed, the positioning part 341 needs a certain external force to disengage from the inner positioning groove 331, thus ensuring that the rotating shaft base 31 remains at the angle corresponding to the inner positioning groove 331. When the user applies external force to continue rotating the rotating shaft base 31, the positioning part 341 can disengage from the positioning groove 12b under the action of the compression spring 35, and the rotating shaft base 31 can continue to rotate around the Z-axis to another angle. In some embodiments, multiple positioning grooves 12b can also be provided on the inner side of the ring of the wear-resistant part 12 to achieve positioning of the rotating connector 2 at multiple different rotation angles.

[0056] In the illustrated embodiment, the inner ring of the positioning seat 33 is provided with an inner positioning groove 331 at 90° intervals around the circumference. The positioning cam 34 reciprocates radially through the compression spring 35, so that when the rotating shaft base 31 rotates, the positioning cam 34 achieves the effect of four-point positioning in the inner positioning grooves 331 at four different angles of the positioning seat 33.

[0057] Please refer to the following: Figure 1 , Figure 9 , Figure 10 The bracket 100 for electronic device accessories has three states— Figure 1 The initial state shown Figure 9 The stop state shown and Figure 10The over-folding state is shown in the diagram. During normal use, the support member 10 rotates around the main axis O1, and the bracket 100 switches between the initial state and the stopped state. In case of an accident, such as when the electronic device falls during the support process or other over-folding forces act on the support member 10 which is already in the stopped state, the external force acting on the bearing seat 22 of the rotating shaft connector 20 resists the anti-preload torque of the torsion spring 24, thereby causing the first rotating shaft 21 and the bearing seat 22 to rotate around the second rotating shaft 23 and lift out of the clearance position of the rotating shaft base 31. As the rotating shaft connector 20 is lifted, the support member 10 can continue to open until it fits against the back plate 210, as shown in the diagram. Figure 8 The state shown is the over-folding state.

[0058] Please refer to the following: Figure 1 , Figure 11A and Figure 12A In the initial state, the support member 10 and the rotating shaft connector 20 are completely housed in the back plate 210 of the housing 200, that is, the angle between the support member 10 and the back plate 210 of the housing 200 is 0°.

[0059] It should be noted that, in the initial state, the support member 10 is at a horizontal angle, and the angle between the line connecting the main axis O1 to the fixed axis O2 and the hinge 12 is less than 180°. Figure 11A As shown in the diagram. That is, in the initial state, the line connecting the main axis O1 to the fixed axis O2 is not on the same plane as the connecting portion 122 of the hinge 12; that is, the line connecting the main axis O1 to the fixed axis O2 forms an angle with the connecting portion 122 of the hinge 12, and the first rotating shaft 21 is closer to the bottom of the mounting groove 212 in the Z-axis direction relative to the second rotating shaft 23. The purpose of this arrangement is to avoid the dead point position where the line connecting the hinge 12 and the main axis O1 to the fixed axis O2 forms a 180° angle. Simultaneously, it allows the support member 10 to generate a downward component force on the first rotating shaft 21 during the initial instant of rotation around the main axis O1, pressing the first rotating shaft 21 into its current position and preventing rotation around the fixed axis O2, which would cause motion disorder.

[0060] like Figure 12AAs shown, the bearing seat 22 is wide at one end and narrow at the other. The width of the end near the first rotating shaft fixing hole 221 is greater than the width of the end near the second rotating shaft fixing hole 222, making its cross-section on the plane perpendicular to the fixed axis O2 quasi-right trapezoidal. When the bearing seat 22 is located in the bearing seat clearance groove 213, the first rotating shaft fixing hole 221 and the second rotating shaft fixing hole 222 are not at the same height relative to the back plate 210. The second rotating shaft fixing hole 222 is higher than the first rotating shaft fixing hole 221, making the second rotating shaft 23 and the first rotating shaft 21 appear to be at different heights. Furthermore, when the bearing seat 22 is located in the bearing seat clearance groove 213, the right-angled trapezoid of the bearing seat 22 is in a state where the straight side is on top and the hypotenuse is on the bottom. The surface where the straight side is located is the upper surface 224 of the bearing seat 22. When the rotating shaft connector 20 is accommodated in the clearance position, the upper surface 224 of the bearing seat 22 is adjacent to the upper surface of the mounting member 30. With the upper surface 224 of the bearing seat 22 as a reference surface, the distance from the first rotating shaft fixing hole 221 to the upper surface 224 of the bearing seat 22 is greater than the distance from the second rotating shaft fixing hole 222 to the upper surface 224 of the bearing seat 22.

[0061] Please refer to the following: Figure 9 , Figure 11B and Figure 12B In the stopped position, the support member 10 opens from the storage slot 211 and forms a preset stopping angle with the back plate 210. The upper surface of the blocking part 111 abuts against the upper end wall of the first rotating shaft clearance groove 312 to restrict the support member 10 from continuing to rotate relative to the first rotating shaft 21, thereby maintaining it at the stopped angle. At this time, the rotating shaft connector 20 is still completely stored in the back plate 210 of the housing 200, and the upper surface 224 of the bearing seat 22 is flush with the top surface of the support member 10, the top surface of the mounting part 30, and the back plate 210. In the stopped position, the size of the stopping angle between the support member 10 and the back plate 210 can be adjusted as needed; for example, the stopping angle can be set to approximately 120°.

[0062] Please refer to the following: Figure 10 , Figure 11C and Figure 12C In the over-folded state, the pivot connector 20 rotates around the fixed axis O2 under the action of the over-folding force and is lifted from the pivot base 31. Then, as the second pivot 23 rotates, it protrudes from the back plate 210. The support member 10 can then continue to rotate relative to the back plate 210 to 180° and fit against the back plate 210 on the other side.

[0063] The torsion spring 24, positioned at the second pivot 23 (fixed axis O2), ensures that when the support member 10 is bent to 180°, the deformation is much less than the material yield point of the support member 10, preventing functional failure. When the bending force applied to the support member 10 disappears, the torsion spring 24 allows the support member 10 to automatically return to its stop position.

[0064] The aforementioned bracket 100 achieves movement by combining the main axis O1 (moving axis) and the fixed axis O2 (fixed axis). When the support member 10 moves from the initial state to the stop state, it rotates around the main axis O1. When it rotates again, the support member 10 and the rotating shaft connector 20 rotate around the fixed axis O2, so that the support member 10 can move relative to the back plate 210 within the range of 0° to 180°.
