[0063] For a better understanding of the technical solutions of the present application, the embodiments of the present application are described in detail below with reference to the drawings.

[0064] It should be clear that the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the present application.

[0065] The terms used in the embodiments of the present application are only for the purpose of describing the specific embodiments, and are not intended to limit the present application. The singular forms "a", "an" and "the" used in the embodiments of the present application and the appended claims are also intended to include the plural forms, unless the context clearly indicates otherwise.

[0066] It should be understood that the term "and / or" used herein is only to describe the association relationship of the associated objects, which means that there can be three relationships, for example, A and / or B, which can represent the three cases of A alone, A and B together, and B alone. In addition, the character " / " herein generally represents an "or" relationship between the front and rear associated objects.

[0067] 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.

[0068] As shown in Figure 1 and Figure 2 , the present application provides an electronic device accessory, which comprises an accessory body 5 and a support assembly 4, the accessory body 5 is provided with a mounting groove 51, and the support assembly 4 is connected with the accessory body 5 through the mounting groove 51.

[0069] When the support assembly 4 is in the storage state, the support assembly 4 can be completely installed in the mounting groove 51, so that the side of the accessory body 5 provided with the mounting groove 51 is approximately planar, and when the support assembly 4 is in the unfolded state, the support assembly 4 extends out of the mounting groove 51, so that the electronic device accessory can stand on the desktop.

[0070] As shown in Figure 2 , Figure 3 and Figure 4 , the present application also provides a support assembly 4, which comprises a base 41, a connecting device 100 and a support 42, the connecting device 100 comprises a first rotating piece 1, a second rotating piece 2 and a connecting piece 3, the first end of the connecting piece 3 is rotatably connected with the first rotating piece 1, the other end of the connecting piece 3 is rotatably connected with the second rotating piece 2, and the second rotating piece 2 is connected with the base 41.

[0071] The support 42 is installed on the first rotating piece 1, the second rotating piece 2 is installed in the mounting groove 51 through the base 41, when the connecting device 100 is in the storage state, the connecting device 100 is located in the mounting groove 51, and the support 42 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 the end of the connecting piece 3 connected with the first rotating piece 1 can extend out of the mounting groove 51, and in the process of rotating the first rotating piece 1 relative to the connecting piece 3, the possibility of interference between the support 42 and the side wall of the mounting groove 51 is reduced. When the connecting device 100 is in the supporting state, there is an included angle between the support 42 and the accessory body 5, which can support the electronic device accessory when the electronic device accessory is placed on the desktop.

[0072] AsFigure 5 and Figure 6 As shown, the connector 3 in the connecting device 100 includes a plurality of laminates 31. The laminates 31 include a main body 311, a first connecting portion 312, and a second connecting portion 313. Along the length of the connector 3, the first connecting portion 312 and the second connecting portion 313 are located at opposite ends of the main body 311. The first connecting portion 312 is rotationally connected to the first rotating member 1, and the second connecting portion 313 is rotationally connected to the second rotating member 2. Along the width of the connector 3, the plurality of laminates 31 are arranged side by side, with adjacent laminates 31 abutting against each other. The first connecting portion 312 of each laminate 31 is connected, and the second connecting portion 313 of each laminate 31 is also connected, thereby connecting the plurality of laminates 31.

[0073] Compared to the existing connector 3 as a whole structure, the connector 3 is formed by winding and deforming a sheet of steel. The plasticity and toughness of the steel are affected during the deformation process. The distortion of the lattice and the entanglement of dislocations during the deformation of the steel make the steel more likely to break when subjected to force, resulting in a decrease in the plasticity of the deformed steel. The deformation process also affects the fatigue performance and corrosion resistance of the steel, making it prone to breakage when subjected to external force. The connector 3 in the embodiment of the present application is composed of a plurality of interconnected laminations 31. Each lamination 31 can be formed by processes such as casting and cutting. The forming process does not cause deformation of the steel, which can improve the strength of the connector 3 and reduce the possibility of deformation of the connecting device 100 when it is subjected to a large external force. Compared to the connector 3 as a whole structure, the laminations 31 are thinner, which is easier to process, thereby improving the processing accuracy of the connector 3.

[0074] like Figure 6 As shown, in one possible embodiment, multiple laminations 31 are fixedly connected and can be further fixed by welding. During the welding process, the high temperature melts the welding rod and the metal at the weld, forming a weld. The connector 3 includes a first weld 32 and a second weld 33. The first weld 32 and the second weld 33 both extend along the width of the connector 3, thereby fixing the multiple laminations 31. The first weld 32 is located on the first connecting portion 312, fixing the multiple first connecting portions 312 together. The second weld 33 is located on the second connecting portion 313, fixing the multiple second connecting portions 313 together.

[0075] The first connecting part 312 and the second connecting part 313 are provided with through holes, so that the first connecting part 312 can be rotatably connected with the first rotating part 1 through a rotating shaft, the second connecting part 313 can be rotatably connected with the second rotating part 2 through a rotating shaft, the first weld 32 and the second weld 33 are respectively located in the first connecting part 312 and the second connecting part 313, so that the plurality of first connecting parts 312 are fixedly connected, the plurality of second connecting parts 313 are fixedly connected, and the possibility of dislocation of the through hole in the first connecting part 312 and the through hole in the second connecting part 313 can be reduced, so that the rotating shaft can rotate in the through hole.

[0076] As shown in Figure 6 , in a possible embodiment, the connecting piece 3 includes a third weld 34 and a fourth weld 35, the third weld 34 is located at one end of the main body part 311 close to the first connecting part 312, and the fourth weld 35 is located at one end of the main body part 311 close to the second connecting part 313, so that the two ends of the main body part 311 are fixedly connected.

[0077] The third weld 34 and the fourth weld 35 are respectively located close to the first connecting part 312 and the second connecting part 313, which can further improve the connection strength of the plurality of first connecting parts 312 and the plurality of second connecting parts 313, and reduce the possibility of dislocation of the plurality of through holes.

[0078] As shown in Figure 6 , in a possible embodiment, a first welding part 311a is arranged at the connection between the main body part 311 and the first connecting part 312, the first welding part 311a protrudes from the main body part 311, and the third weld 34 is located at the first welding part 311a. A second welding part 311b is arranged at the connection between the main body part 311 and the second connecting part 313, the second welding part 311b protrudes from the main body part 311, and the fourth weld 35 is located at the second welding part 311b.

[0079] Taking the first welding part 311a as an example, the first welding part 311a is arranged at the connection between the main body part 311 and the first connecting part 312, which facilitates the formation of the third weld 34, increases the strength at the third weld 34, and increases the fixing strength of one end of the main body part 311 close to the first connecting part 312. Similarly, the second welding part 311b can increase the fixing strength of one end of the main body part 311 close to the second connecting part 313.

[0080] As shown in Figure 6 , Figure 7 , and Figure 8 , in a possible embodiment, along the width direction of the connecting piece 3, one side of the main body part 311 is provided with a protruding part 314, and the other side is provided with a recessed part 315. When the plurality of laminations 31 are arranged side by side, the protruding part 314 of one of the adjacent main body parts 311 extends into the recessed part 315 of the other, so that the adjacent main body parts 311 are matched in concave-convex.

[0081] The protruding portion 314 and the recessed portion 315 are located at the middle of the body portion 311, and the protruding portion 314 extends into the recessed portion 315, and the side wall of the protruding portion 314 abuts against the inner wall of the recessed portion 315, so as to limit the relative position of the adjacent laminates 31, and the protruding portion 314 and the recessed portion 315 cooperate to reduce the possibility of misalignment or dispersion of the plurality of laminates 31, thereby further improving the strength of the connecting piece 3. Before the plurality of laminates 31 are welded and fixed, the protruding portion 314 and the recessed portion 315 in the adjacent body portions 311 cooperate to determine the relative position of the plurality of laminates 31, thereby reducing the welding difficulty and improving the production efficiency and precision of the body portion 311.

[0082] In a possible embodiment, the surface of the body portion 311 includes a plurality of protruding portions 314 and a plurality of recessed portions 315, and the protruding portion 314 and the recessed portion 315 on one side of the adjacent two body portions 311 are correspondingly arranged.

[0083] The body portion 311 is provided with a plurality of recessed portions 315 and protruding portions 314, and when the plurality of laminates 31 are arranged side by side, the protruding portion 314 and the recessed portion 315 can cooperate with each other to limit the relative position of the adjacent two body portions 311 and reduce the possibility of misalignment of the adjacent laminates 31. The plurality of protruding portions 314 and recessed portions 315 arranged on the body portion 311 can further limit the relative position of the adjacent two body portions 311 and further reduce the possibility of misalignment or dispersion of the plurality of laminates 31.

[0084] In a possible embodiment, the body portion 311 is provided with a plurality of protruding portions 314 on one side and a plurality of recessed portions 315 on the other side. Alternatively, the body portion 311 is provided with a plurality of protruding portions 314 and recessed portions 315 on both sides, and the protruding portion 314 and the recessed portion 315 in the adjacent two body portions 311 are correspondingly arranged.

[0085] The protruding portion 314 and the recessed portion 315 can be arranged on both sides of the body portion 311 or on the same side of the body portion 311, and when the plurality of laminates 31 are arranged side by side, the protruding portion 314 of one of the adjacent body portions 311 can extend into the recessed portion 315 of the other. The protruding portion 314 and the recessed portion 315 are arranged on both sides of the body portion 311, which reduces the processing difficulty of the body portion 311 and is conducive to improving the production efficiency of the laminate 31. When the protruding portion 314 and the recessed portion 315 are arranged on the same side of the body portion 311, the two sides of the body portion 311 are both stepped surfaces, which can improve the strength of the body portion 311.

[0086] As shown in FIG. 1, Figure 6 In a possible embodiment, the thicknesses of the plurality of laminates 31 in the connecting piece 3 are the same.

[0087] The thicknesses of the plurality of laminations 31 are the same, so that the force borne by each lamination 31 in the connecting piece 3 is more uniform, thereby improving the force that the connecting piece 3 can bear. The thicknesses of the laminations 31 are the same, so that the plurality of laminations 31 can be processed through a standardized process, thereby improving the processing efficiency of the laminations 31 and improving the production efficiency of the connecting piece 3.

[0088] As shown in Figure 6 to Figure 10 In a possible embodiment, the lamination 31 includes a first lamination group and a second lamination group, and the two sides of the first lamination group each have the second lamination group along the width direction of the connecting piece 3. The first lamination group includes a plurality of first laminations 316, which are arranged side by side along the width direction of the connecting piece 3 and are fixed by welding, and the second lamination group includes a plurality of second laminations 317, which are arranged side by side and are fixed by welding. The first connecting portion 312 of the first lamination 316 and the second connecting portion 313 of the first lamination 316 each are provided with a first opening 316a, which penetrates the first lamination 316 along the width direction of the connecting piece 3.

[0089] After the plurality of first laminations 316 are arranged side by side, the plurality of first openings 316a are in communication with each other, and two limiting openings are formed on the connecting piece 3 to accommodate the limiting blocks 11 on the first rotating piece 1 and the second rotating piece 2, so as to limit the rotation angle of the first rotating piece 1 and the second rotating piece 2 relative to the connecting piece 3. The thickness and the number of the first laminations 316 can be set according to the width of the limiting blocks 11 on the first rotating piece 1 and the second rotating piece 2, so that the limiting blocks 11 can move in the limiting openings. The opening size of the first opening 316a located at the first connecting portion 312 and the opening size of the first opening 316a located at the second connecting portion 313 can be consistent or inconsistent, which is set according to the angle at which the first rotating piece 1 and the second rotating piece 2 need to rotate relative to the connecting piece 3.

[0090] As shown in Figure 9 In a possible embodiment, the side wall of one end of the first opening 316a is the main body portion 311, and the third welding seam 34 and the fourth welding seam 35 are located on the side of the main body portion 311 away from the first opening 316a.

[0091] The third welding seam 34 and the fourth welding seam 35 are used to connect the main body portion 311, and a first welding portion 311a and a second welding portion 311b are respectively arranged at the third welding seam 34 and the fourth welding seam 35, so as to improve the reliability of the plurality of laminations 31 after being connected, and the first welding portion 311a and the second welding portion 311b protrude from the main body portion 311. By arranging the third welding seam 34 and the fourth welding seam 35 on the side away from the first opening 316a, the possibility that the first welding portion 311a and the second welding portion 311b affect the movement of the limiting blocks 11 in the limiting openings can be reduced.

[0092] AsFigure 6 and Figure 10 As shown in FIG. 3, in one possible embodiment, the connecting piece 3 further comprises a third lamination 318 located between the first lamination group and the second lamination group. The first connecting portion 312 and the second connecting portion 313 in the third lamination 318 each comprise a second opening 318a and a mounting portion 318b, which are arranged side by side along the width direction of the connecting piece 3, and the second opening 318a is located on the side of the third lamination 318 close to the first lamination 316 and communicates with the first opening 316a, and the mounting portion 318b is located on the side of the third lamination 318 close to the second lamination group and is connected with the second lamination 317.

[0093] The second opening 318a communicates with the first opening 316a, and after the plurality of laminations 31 are arranged side by side, the second opening 318a and the first opening 316a enclose a limiting opening. The mounting portion 318b is located on the side close to the second lamination group, so that the first connecting portion 312 and the second connecting portion 313 in the third lamination 318 close to the second lamination 317 are attached to the second lamination 317, which can improve the reliability of the connection between the third lamination 318 and the second lamination 317.

[0094] In one possible embodiment, along the width direction of the connecting piece 3, the width of the second opening 318a in the third lamination 318 is less than or equal to 90% of the thickness of the third lamination 318.

[0095] The second opening 318a communicates with the first opening 316a to form a limiting opening, so the width of the second opening 318a can be determined according to the required width of the opening. If the width of the second opening 318a is greater than 90% of the thickness of the third lamination 318, the thickness of the portion of the third lamination 318 attached to the first connecting portion 312 and the second connecting portion 313 in the second lamination 317 is smaller, which can reduce the reliability of the connection between the third lamination 318 and the second lamination 317. The width of the second opening 318a can be 90%, 85%, 80% or the like of the thickness of the third lamination 318, for example, the thickness of the third lamination 318 is 0.35 mm, and the width of the second opening 318a can be 0.3 mm.
