[0060] In order to better understand the technical solution of the present application, the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0061] It should be clear that the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0062] The terms used in the embodiments of the present application are for the purpose of describing specific embodiments only and are not intended to limit the present application. The singular forms "a", "an", "the" and "the" used in the embodiments of the present application and the appended claims are also intended to include plural forms unless the context clearly indicates otherwise.

[0063] It should be understood that the term "and / or" as used herein is merely a description of the relationship between associated objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, or B exists alone. Furthermore, the character " / " in this document generally indicates that the associated objects are in an "or" relationship.

[0064] It should be noted that the "upper", "lower", "left", "right" and other orientation words described in the embodiments of the present application are described in the angle shown in the drawings, and should not be understood as a limitation on the embodiments of the present application. In addition, in the context, it should also be understood that when referring to one element connected to another element "on" or "under", it can not only be directly connected to another element "on" or "under", but also indirectly connected to another element "on" or "under" through an intermediate element.

[0065] As shown in Figure 1 and Figure 2 , the electronic device accessory provided by the embodiments of the present application includes an accessory body 6 and a support assembly 5, the accessory body 6 is provided with a mounting groove 61, and the support assembly 5 is connected with the accessory body 6 through the mounting groove 61.

[0066] When the support assembly 5 is in the storage state, the support assembly 5 can be completely installed in the mounting groove 61, so that the side of the accessory body 6 provided with the mounting groove 61 is approximately planar, and when the support assembly 5 is in the unfolded state, the support assembly 5 extends out of the mounting groove 61, so that the electronic device accessory can stand on the desktop.

[0067] As shown in Figure 3 and Figure 4 , the embodiments of the present application also provide a support assembly 5, which includes a base 51, a connecting device 100 and a support 52, the connecting device 100 includes a first rotating piece 1, a second rotating piece 2 and a connecting piece 3, the first end of the connecting piece 3 is connected with the first rotating piece 1, the second end of the connecting piece 3 is connected with the second rotating piece 2, and the second rotating piece 2 is connected with the base 51.

[0068] The support 52 is installed in the first rotating piece 1, and the second rotating piece 2 is installed in the mounting groove 61 through the base 51, when the connecting device 100 is in the storage state, the connecting device 100 is located in the mounting groove 61, and the support 52 can shield the first rotating piece 1, the second rotating piece 2 and the connecting piece 3, which reduces the possibility of dust and other impurities falling into the first rotating piece 1, the second rotating piece 2 and the connecting piece 3, and can improve the service life of the connecting device 100, and also can make the electronic device accessory more beautiful. In the process of changing the connecting device 100 from the storage state to the unfolded state, the connecting piece 3 rotates relative to the second rotating piece 2, so that one end of the connecting piece 3 connected with the first rotating piece 1 can extend out of the mounting groove 61, and in the process of rotating the first rotating piece 1 relative to the connecting piece 3, the possibility of interference between the support 52 and the side wall of the mounting groove 61 is reduced. When the connecting device 100 is in the support state, there is an included angle between the support 52 and the accessory body 6, and when the electronic device accessory is placed on the desktop, the electronic device accessory can be supported.

[0069] As shown in Figure 6 , Figure 7 andFigure 8 As shown, the first end of the connecting piece 3 is provided with a first stop opening 31, the first rotating piece 1 comprises a first stop block 11, the first stop block 11 is located in the first stop opening 31, and the first stop block 11 moves in the first stop opening 31 when the first rotating piece 1 rotates relative to the connecting piece 3. The second end of the connecting piece 3 is provided with a second stop opening 34, the second rotating piece 2 comprises a second stop block 21, the second stop block 21 is located in the second stop opening 34, and the second stop block 21 moves in the second stop opening 34 when the connecting piece 3 rotates relative to the second rotating piece 2. The first stop opening 31 comprises a first stop surface 311, and the second stop opening 34 comprises a second stop surface 341. When the connecting device 100 is in the unfolded state, the first stop block 11 abuts against the first stop surface 311, and the second stop block 21 abuts against the second stop surface 341.

[0070] The support piece 52 is installed on the first rotating piece 1, and the support piece 52 drives the first rotating piece 1 to rotate relative to the connecting piece 3 during unfolding of the support assembly 5, thereby being able to drive the connecting piece 3 to rotate relative to the second rotating piece 2. After the support piece 52 is separated from the installation groove 61, the second stop block 21 abuts against the second stop surface 341, and the angle of rotation of the connecting piece 3 relative to the second rotating piece 2 is limited. The support piece 52 drives the first rotating piece 1 to rotate to a preset angle, so that the first stop block 11 abuts against the first stop surface 311 when the connecting device 100 is in the unfolded state, thereby limiting the angle of rotation of the first rotating piece 1 relative to the connecting piece 3, limiting the included angle and relative position of the support piece 52 and the accessory body 6, and improving the stability of the connecting device 100 in the unfolded state.

[0071] As shown in Figure 5 and Figure 6 In a possible embodiment, the width of the first stop opening 31 is greater than the width of the first stop block 11, and the width of the second stop opening 34 is greater than the width of the second stop block 21.

[0072] The first stop block 11 is located in the first stop opening 31, and the width of the first stop opening 31 is greater than the width of the first stop block 11, thereby facilitating movement of the first stop block 11 in the first stop opening 31 and facilitating rotation of the first rotating piece 1 relative to the connecting piece 3. The second stop block 21 is located in the second stop opening 34, and the width of the second stop opening 34 is greater than the width of the second stop block 21, thereby facilitating movement of the second stop block 21 in the second stop opening 34 and facilitating rotation of the connecting piece 3 relative to the second rotating piece 2.

[0073] As shown in Figure 7 and Figure 8As shown, in a possible embodiment, the connecting device 100 comprises a rotating shaft 4, the rotating shaft 4 comprises a first rotating shaft 41 and a second rotating shaft 42, the first end of the connecting piece 3 is provided with a first shaft sleeve 32, the first rotating shaft 41 is arranged in the first shaft sleeve 32, the second end is provided with a second shaft sleeve 35, the second rotating shaft 42 is sleeved in the second shaft sleeve 35, the first rotating part 1 is rotatably connected with the first end through the first rotating shaft 41, the second rotating part 2 is rotatably connected with the second end through the second rotating shaft 42, so that the connecting piece 3 is rotatably connected with the first rotating part 1 and the second rotating part 2. The first stop opening 31 is arranged in the first shaft sleeve 32, and the second stop opening 34 is arranged in the second shaft sleeve 35. The corresponding central angle of the first stop opening 31 on the first shaft sleeve 32 is greater than the corresponding central angle of the second stop opening 34 on the second shaft sleeve 35.

[0074] The corresponding central angle of the first stop opening 31 is greater than the corresponding central angle of the second stop opening 34, so that the angle of rotation of the first rotating part 1 relative to the connecting piece 3 is greater than the angle of rotation of the connecting piece 3 relative to the second rotating part 2. As shown, Figure 2 As shown, the connecting piece 3 rotates relative to the second rotating part 2, so that the first end of the connecting piece 3 is separated from the mounting groove 61 on the accessory body 6, so as to reduce the possibility of interference between the support 52 and the side wall of the mounting groove 61. Since the thickness of the accessory body 6 is small, the depth of the mounting groove 61 is also small, and the angle of rotation of the connecting piece 3 relative to the second rotating part 2 is small, so that the first end of the connecting piece 3 can be separated from the mounting groove 61, and the first rotating part 1 can drive the support 52 to rotate. The first rotating part 1 drives the support 52 to rotate relative to the connecting piece 3 to change the included angle between the support 52 and the accessory body 6, so that the electronic equipment accessory can stand on the desktop. The angle of rotation of the first rotating part 1 relative to the connecting piece 3 is large, which increases the included angle between the support 52 and the accessory body 6, thereby improving the stability of the electronic equipment accessory after standing on the desktop.

[0075] In a possible embodiment, the first stop opening 31 limits the angle of rotation of the first rotating part 1 relative to the connecting piece 3. The corresponding central angle of the first stop opening 31 in the first shaft sleeve 32 is greater than or equal to the angle of rotation of the first rotating part 1 from the storage state to the unfolded state.

[0076] The first stop block 11 protrudes from the first connecting piece 3, and abuts against the side wall in the first stop opening 31 to limit the angle at which the first rotating piece 1 can rotate relative to the connecting piece 3. If the corresponding central angle of the first stop opening 31 in the first shaft sleeve 32 is smaller than the angle at which the first rotating piece 1 needs to rotate relative to the connecting piece 3, the first rotating piece 1 cannot be rotated to the preset angle when the connecting device 100 is in the unfolded state, thereby causing the included angle between the support piece 52 and the accessory main body 6 to be small, and the support effect to be poor. If the corresponding central angle of the first stop opening 31 in the first shaft sleeve 32 is greater than or equal to the angle at which the first rotating piece 1 needs to rotate relative to the connecting piece 3, the first rotating piece 1 can be rotated to the preset angle when the connecting device 100 is in the unfolded state. When the first rotating piece 1 needs to be rotated by 134° relative to the connecting piece 3 from the storage state to the unfolded state, the corresponding central angle of the first stop opening 31 in the first shaft sleeve 32 is 200°, so that the first rotating piece 1 can be rotated to the preset angle.

[0077] In a possible embodiment, the second stop opening 34 limits the angle at which the second rotating piece 2 rotates relative to the connecting piece 3. The corresponding central angle of the second stop opening 34 in the second shaft sleeve 35 is greater than or equal to the angle at which the second rotating piece 2 rotates from the storage state to the unfolded state.

[0078] The second stop block 21 protrudes from the second rotating piece 2, and abuts against the side wall of the second stop opening 34 to limit the angle at which the second rotating piece 2 can rotate relative to the connecting piece 3. If the corresponding central angle of the second stop opening 34 in the second shaft sleeve 35 is smaller than the angle at which the second rotating piece 2 needs to rotate, the second rotating piece 2 cannot be rotated to the preset angle when the connecting device 100 is in the unfolded state, thereby causing the first end of the connecting piece 3 to be unable to be separated from the mounting groove 61, and the support piece 52 to be unable to be normally opened. If the corresponding central angle of the second stop opening 34 in the second shaft sleeve 35 is greater than or equal to the angle at which the second rotating piece 2 rotates, the second rotating piece 2 can be rotated to the preset angle when the connecting device 100 is in the unfolded state, so that the first end of the connecting piece 3 can be separated from the mounting groove 61, and the support piece 52 can be normally opened. When the second rotating piece 2 rotates by 23° from the storage state to the unfolded state, the corresponding central angle of the second stop opening 34 in the second shaft sleeve 35 can be 60°, so that the first end of the connecting piece 3 can be separated from the mounting groove 61.

[0079] As shown in FIG. 1, Figure 6 In a possible embodiment, the first stop block 11 is perpendicular to the first stop face 311, and the second stop block 21 is perpendicular to the second stop face 341 when the connecting device 100 is in the unfolded state.

[0080] When the first stop block 11 abuts against the first stop surface 311, the first stop block 11 is perpendicular to the first stop surface 311, which can reduce the possibility of the first stop block 11 sliding relative to the first stop surface 311. When the second stop block 21 abuts against the second stop surface 341, the second stop block 21 is perpendicular to the second stop surface 341, which can reduce the possibility of the second stop block 21 sliding relative to the second stop surface 341, and is beneficial to improve the stability of the connecting device 100 in the unfolded state.

[0081] When the end of the first stop block 11 in contact with the first stop surface 311 is a plane, the first stop block 11 is in surface contact with the first stop surface 311. When the end of the second stop block 21 in contact with the second stop surface 341 is a plane, the second stop block 21 is in surface contact with the second stop surface 341.

[0082] When the connecting device 100 is in the unfolded state, the contact area of the first stop block 11 and the first stop surface 311 is increased, and the contact area of the second stop block 21 and the second stop surface 341 is increased, thereby improving the stability of the connecting device 100 in the unfolded state.

[0083] As shown in Figure 6 , in a possible embodiment, the central axis of the first shaft sleeve 32 is located in the plane where the first stop surface 311 is located, so that the first stop block 11 is in surface contact with the first stop surface 311 when the connecting device 100 is in the unfolded state. The central axis of the second shaft sleeve 35 is located in the plane where the second stop surface 341 is located, so that the second stop block 21 is in surface contact with the second stop surface 341 when the connecting device 100 is in the unfolded state.

[0084] As shown in Figure 6 , Figure 10 and Figure 11 , in a possible embodiment, the first rotating member 1 includes a third shaft sleeve 12, and the portion of the first rotating shaft 41 protruding from the first shaft sleeve 32 is located in the third shaft sleeve 12, so that the first rotating member 1 and the connecting member 3 are rotationally connected. The third shaft sleeve 12 includes a first accommodating portion 122, and the first stop block 11 and the first shaft sleeve 32 are both located in the first accommodating portion 122, and the first stop block 11 is located in the first stop opening 31 of the first shaft sleeve 32. The second rotating member 2 includes a fourth shaft sleeve 22, and the portion of the second rotating shaft 42 protruding from the second shaft sleeve 35 is located in the fourth shaft sleeve 22, so that the second rotating member 2 and the connecting member 3 are rotationally connected. The fourth shaft sleeve 22 includes a second accommodating portion 221, and the second stop block 21 and the second shaft sleeve 35 are both located in the second accommodating portion 221, and the second stop block 21 is located in the second stop opening 34 of the second shaft sleeve 35.

[0085] Taking the first rotating member 1 as an example, the first rotating member 1 is connected with the first end of the connecting member 3 through the first rotating shaft 41, so the first shaft sleeve 32 and the third shaft sleeve 12 are arranged side by side along the axial direction of the first rotating shaft 41, the first stop opening 31 is located in the first shaft sleeve 32, and the first stop block 11 and the first shaft sleeve 32 are both located in the first accommodating portion 122, so that the first stop block 11 is facilitated to abut against the first stop surface 311 when the connecting device 100 is in the unfolded state. The first stop block 11 abuts against the first stop surface 311 to limit the relative position between the connecting member 3 and the first rotating member 1, the first stop block 11 is located in the first accommodating portion 122, so that the length of the first stop block 11 protruding from the first rotating member 1 is less than the length of the third shaft sleeve 12 protruding from the first rotating member 1, and when the angle of the central angle corresponding to the first stop opening 31 is unchanged, the included angle between the first rotating member 1 and the connecting member 3 when the connecting device 100 is in the unfolded state can be increased.

[0086] As shown in Figure 8 and Figure 9 , in a possible embodiment, the outer wall of the first rotating shaft 41 and the outer wall of the second rotating shaft 42 are both provided with at least one limiting plane 43, and the inner wall of the first shaft sleeve 32 and the inner wall of the second shaft sleeve 35 are both provided with at least one first plane 33. Figure 10 and Figure 11 , the inner wall of the third shaft sleeve 12 and the inner wall of the fourth shaft sleeve 22 are both provided with at least one second plane 121, and the first plane 33 and the second plane 121 both correspond to the limiting plane 43 when the connecting device 100 is in the storage state.

[0087] For example, the first shaft sleeve 32, the first rotating shaft 41 is provided with at least one limiting plane 43, the diameter of the limiting plane 43 is smaller than that of other positions, when the first rotating shaft 41 rotates relative to the first shaft sleeve 32, the first plane 33 is staggered with the limiting plane 43, the pressure between the first rotating shaft 41 and the inner wall of the first shaft sleeve 32 is increased, and then the friction between the first rotating shaft 41 and the first shaft sleeve 32 is increased, when the connecting device 100 is in the unfolded state, the relative position between the first shaft sleeve 32 and the first rotating shaft 41 can be limited, when the connecting device 100 is converted from the storage state to the unfolded state, after the limiting plane 43 in the first rotating shaft 41 is staggered with the first plane 33, the friction between the first rotating shaft 41 and the first shaft sleeve 32 is increased, so that the first rotating shaft 41 can rotate by any angle in the first shaft sleeve 32 and remain stable, and then the first rotating part 1 can drive the support part 52 to remain at any unfolding angle, so as to increase the application scenarios of the connecting device 100. Similarly, the limiting plane 43 cooperates with the first plane 33 in the second shaft sleeve 35, and the second plane 121 in the third shaft sleeve 12 and the fourth shaft sleeve 22 cooperates, so that the connecting part 3 and the second rotating part 2 can remain stable at any angle. When the connecting device 100 is in the storage state, the first plane 33 corresponds to the limiting plane 43, the first plane 33 and the limiting plane 43 can abut, the diameter of the shaft sleeve is smaller than the diameter of the rotating shaft 4, so that the connecting device 100 is more stable when it is in the unfolded state; or the first plane 33 and the limiting plane 43 are approximately parallel with a gap therebetween, the diameter of the shaft sleeve is larger than the diameter of the rotating shaft 4, so that the rotating shaft 4 can rotate relative to the shaft sleeve more easily.

[0088] When only one first plane 33 or second plane 121 is provided in the shaft sleeve, the corresponding central angle of the first plane 33 or second plane 121 in the shaft sleeve is 60° to 80°. For example, the first shaft sleeve 32, if the angle of the corresponding central angle of the first plane 33 in the first shaft sleeve 32 is less than 60°, the diameter of the first plane 33 provided in the first shaft sleeve 32 is smaller than that of the position without the first plane 33, after the limiting plane 43 is staggered with the first plane 33, the friction between the first rotating shaft 41 and the first shaft sleeve 32 is smaller, the first rotating shaft 41 cannot remain stable, if the angle of the corresponding central angle of the first plane 33 in the first shaft sleeve 32 is greater than 80°, the diameter of the first plane 33 provided in the first shaft sleeve 32 is larger than that of the position without the first plane 33, after the limiting plane 43 is staggered with the first plane 33, the friction between the first rotating shaft 41 and the first shaft sleeve 32 is larger, the force required for the first rotating shaft 41 to rotate relative to the first shaft sleeve 32 is larger, it is not convenient to rotate the connecting device 100 from the storage state to the unfolded state, therefore, the corresponding central angle of the first plane 33 in the first shaft sleeve 32 can be 60°, 70°, 80°, etc., and is preferably 70°.

[0089] In one possible embodiment, one of the first sleeve 32 and the third sleeve 12 is fixedly connected to the first rotating shaft 41, and the other is rotatably connected to the first rotating shaft 41, so that the first rotating member 1 can rotate relative to the connecting member 3. One of the second sleeve 35 and the fourth sleeve 22 is fixedly connected to the second rotating shaft 42, and the other is rotatably connected to the second rotating shaft 42, so that the second rotating member 2 can rotate relative to the connecting member 3.

[0090] One of the first sleeve 32 and the third sleeve 12 is fixedly connected to the first rotating shaft 41, and the other is rotatably connected to the first rotating shaft 41, so that when the first rotating member 1 rotates relative to the connecting member 3, one can drive the first rotating shaft 41 to rotate relative to the other, so that when the connecting device 100 is unfolded, the limiting plane 43 of the first rotating shaft 41 is staggered with the first plane 33 in the first sleeve 32 or the second plane 121 in the third sleeve 12, so as to improve the stability of the connecting device 100 when it is in the unfolded state. When the connecting device 100 is changed to the retracted state, the limiting plane 43 of the first rotating shaft 41 is corresponding to the first plane 33 in the first sleeve 32 and the second plane 121 in the third sleeve 12, so as to reduce the possibility of dislocation of the first rotating shaft 41 after the connecting device 100 is opened and closed multiple times.

[0091] like Figure 7 and Figure 8 As shown, in a possible embodiment, the connecting member 3 includes a plurality of laminates 36 . Along the width direction of the connecting member 3 , the plurality of laminates 36 are arranged side by side, and adjacent laminates 36 are connected to each other.

[0092] Connector 3 is composed of multiple laminations 36, which can be secured by welding. This increases the strength of connector 3 and reduces the likelihood of deformation of connector 100 when subjected to significant external forces. Compared to a monolithic connector 3, laminations 36 are thinner, making them easier to machine, thereby improving the machining accuracy of connector 3.

[0093] like Figure 7 As shown, in a possible embodiment, the thicknesses of the plurality of laminations 36 in the connecting member 3 are the same.

[0094] The multiple laminations 36 have the same thickness, which makes the force applied to each lamination 36 in the connector 3 more uniform, thereby increasing the force that the connector 3 can withstand. The uniform thickness of each lamination 36 allows the multiple laminations 36 to be processed using a standardized process, which can improve the processing efficiency of the laminations 36 and thus improve the production efficiency of the connector 3.
