Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of 3C digital accessories, in particular to an electronic equipment accessory. Background Art
[0002] When using electronic devices such as mobile phones and tablets, they are usually equipped with brackets to obtain different support angles. In order to meet the needs of more support angles, a dual-axis linkage structure is proposed to achieve an opening angle range of 0 to 180 degrees. However, during the development and verification process, it was found that a certain damping force needs to be maintained between the rotating shaft connected to the bracket and the corresponding shaft sleeve so that the bracket can be stable at this angle after opening to a certain angle. However, the damping force between the rotating shaft and the shaft sleeve will be lost as the number of rotations increases. When the damping force is lost, there will be slight shaking between the rotating shaft and the connecting part, resulting in slight shaking during support and causing unstable support.

It should be understood that such terms can be interchanged under appropriate circumstances so that the embodiments of the present utility model described herein can be implemented in an order other than those illustrated or described herein.

For example, a process, method, system, product or device comprising a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products or devices.
[0030] It should also be noted that the division of multiple embodiments in the present utility model is only for the convenience of description and should not constitute a special limitation. The features in various embodiments can be combined and mutually referred to without conflict.
[0031] Referring to Figure 1 , an embodiment of the present utility model provides an electronic device accessory, including: a base 20, a double-rotating shaft assembly 30, a support member 40, and an anti-shake structure 50 (refer to Figure 3 ). Referring to Figure 2 and Figure 3 , the double-rotating shaft assembly 30 includes a double-axis linkage member 31, a first rotating shaft 32, and a second rotating shaft 33. The double-axis linkage member 31 has a first bushing portion 311 and a second bushing portion 312. The first rotating shaft 32 is fixedly connected to the base 20 and rotatably connected to the first bushing portion 311. The second bushing portion 312 is located at one end of the double-axis linkage member 31 away from the base 20. The second rotating shaft 33 is rotatably connected to the second bushing portion 312. The support member 40 is fixedly connected to the second rotating shaft 33. The anti-shake structure 50 is connected between the second rotating shaft 33 and the second bushing portion 312, and the anti-shake structure 50 limits the rotation of the second rotating shaft 33 relative to the second bushing portion 312.
[0032] Among them, the electronic device accessory can be, for example, a protective case with a bracket or a mobile power supply with a bracket, etc. The electronic device accessory also includes, for example, a housing 10, and the housing 10 can be the outer shell of accessories such as a protective case or a mobile power supply.Figure 1 Taking a protective case with a bracket as an example for display, the housing 10 includes, for example, a back plate and side frames ( Figure 1 not shown), and the back plate and side frames together enclose a receiving cavity. When the housing 10 is sleeved on an electronic device such as a mobile phone, the electronic device is located in the receiving cavity.
[0033] Referring to Figure 2 , a bracket receiving area 11 is provided on one surface of the housing 10 (for example, the surface of the housing 10 facing away from the receiving cavity, which can be called the back surface of the housing). When the support function is not needed, the support member 40 can be received in the bracket receiving area 11, and at this time, the support member 40 is in a received state. When it is necessary to open the support member 40 to achieve the support function, the support member 40 and the biaxial linkage member 31 can be rotated relative to the base 20 synchronously or the support member 40 can be rotated around the biaxial linkage member 31 to open the support member 40 to an appropriate angle. For example, first, the second rotating shaft 33 remains relatively stationary with respect to the biaxial linkage member 31, and the biaxial linkage member 31 rotates around the first rotating shaft 32, and the support member 40 and the biaxial linkage member 31 rotate relative to the base 20 synchronously to Figure 4 the state shown in the figure. At this time, the opening state of the support member 40 can be called the intermediate opening angle. At this time, the opening angle of the support member 40 reaches, for example, 80° to 100°, and specifically can be 90°. If a larger opening angle is required, the biaxial linkage member 31 remains relatively stationary with respect to the first rotating shaft 32, the second rotating shaft 33 rotates, and the support member 40 rotates around the biaxial linkage member 31 to continue opening, and an opening angle of 180° can be reached. At this time, the opening state of the support member 40 can be called the maximum opening angle. When closing the support member 40, first, the support member 40 rotates around the biaxial linkage member 31 from the maximum opening angle to the intermediate opening angle, and then the support member 40 and the biaxial linkage member 31 rotate synchronously, from the intermediate opening angle to the received state. During the opening and closing process of the support member 40 described above, when the support member 40 rotates between the maximum opening angle and the intermediate opening angle, the second rotating shaft 33 rotates with the second shaft sleeve portion 312. As the number of rotations increases, the damping force between the second rotating shaft 33 and the second shaft sleeve portion 312 will be lost. However, when the support member 40 is opened to the required angle for support, if the damping force between the second rotating shaft 33 and the second shaft sleeve portion 312 is insufficient, the support member 40 will shake, which may cause the problem of unstable support.
[0034] In some embodiments, referring to Figure 4, a limiting protrusion 71 is provided on the first bushing portion 311, and a limiting groove 72 matching the limiting protrusion 71 is provided on the base 20. The double-shaft linkage 31 is rotationally connected to the second rotating shaft 33 in a limited manner through the limiting protrusion 71 and the limiting groove 72. Thus, when the support member 40 rotates to the intermediate opening angle, the limiting protrusion 71 rotates into the limiting groove 72, so that the double-shaft linkage 31 no longer rotates relative to the base 20, and during the process of the support member 40 continuing to rotate to the maximum opening angle, the support member 40 rotates relative to the double-shaft linkage 31. When the support member 40 closes from the intermediate opening angle, the limiting protrusion 71 can be disengaged from the limiting groove 72, and the double-shaft linkage 31 and the support member 40 can rotate relative to the base 20. Among them, the limiting protrusion 71 is, for example, a strip-shaped protrusion extending along the axial direction of the first rotating shaft 32, and the surface of the limiting protrusion 71 is arc-shaped, and the corresponding limiting groove 72 is also an arc-shaped groove, so that the cooperation between the limiting protrusion 71 and the limiting groove 72 is smoother.
[0035] In the embodiment of the present utility model, by adding an anti-shake structure 50 between the second rotating shaft 33 and the second bushing portion 312, the rotation of the second rotating shaft 33 relative to the second bushing portion 312 can be limited, so that the second rotating shaft 33 and the second bushing portion 312 do not only rely on the damping force to maintain stability, so that after the support member 40 reaches the required angle, it can be stabilized at this angle through the anti-shake structure 50, realizing a stable support.
[0036] In some embodiments, referring to Figure 3 , Figures 5 to 8 , the anti-shake structure 50 includes a first limiting portion 51 fixedly connected to the second rotating shaft 33 and a second limiting portion 52 fixedly connected to the second bushing portion 312. The first limiting portion 51 and the second limiting portion 52 can abut against each other to limit the rotation of the second rotating shaft 33 relative to the second bushing portion 312. By abutting against each other, the second rotating shaft 33 and the second bushing portion 312 are mutually limited, and the structure is simpler.
[0037] Specifically referring to Figure 3 , Figure 5 and Figure 6 , a boss is formed on the outer surface of the second bushing portion 312, and the second limiting portion 52 includes the boss. The electronic device accessory further includes a connecting member 60. The connecting member 60 is connected to the end of the second rotating shaft 33 outside the second bushing portion 312 and includes the first limiting portion 51. The first limiting portion 51 is located on one side of the boss along the circumference of the second rotating shaft 33. Specifically, the first limiting portion 51 is located on the side of the boss facing away from the bracket storage area 11. Taking the storage state of the support member 40 as a reference, if the support member 40 is stacked above the bracket storage area 11, then the first limiting portion 51 is located above the boss in the storage state. Through the cooperation of the first limiting portion 51 and the boss, the support member 40 can be prevented from shaking in the closing direction, and stable support can be ensured.
[0038] In some embodiments, the support member 40 is fixedly connected to the second rotating shaft 33 through the connecting member 60. That is, the connecting member 60 serves as both a medium for connecting the support member 40 and the second rotating shaft 33 and a medium for connecting the first limiting portion 51 and the second rotating shaft 33. Or it can also be considered that the first limiting portion 51 is provided on the connecting member 60 for connecting the second rotating shaft 33 and the support member 40, which is more convenient for manufacturing. The connecting member 60 is, for example, riveted to the support member 40.
[0039] In some embodiments, referring to Figure 6 , in the direction in which the boss protrudes from the surface of the second bushing portion 312, the height D2 of the boss is greater than the height D1 of the first limiting portion 51. This can prevent slippage and failure between the first limiting portion 51 and the boss, and ensure effective abutment between the boss and the first limiting portion 51.
[0040] In some embodiments, referring to Figure 7 and Figure 8 , a groove surrounding the second rotating shaft 33 in the circumferential direction of the rotating shaft is formed on the inner surface of the second bushing portion 312, and the second limiting portion 52 includes this groove. A protrusion is provided on the second rotating shaft 33, and the first limiting portion 51 includes this protrusion. The protrusion is located in the groove and can abut against opposite side walls of the groove. Through the cooperation of the groove and the protrusion, the two rotating directions of the second rotating shaft 33 can be limited, and the anti-wobbling effect is more comprehensive.
[0041] In some embodiments, the anti-wobbling structure 50 can simultaneously have the combination of the first limiting portion 51 shown in Figure 5 and Figure 6 being provided on the connecting member 60 and cooperating with the boss, and the combination of the protrusion and the groove shown in Figure 7 and Figure 8 .
[0042] In some embodiments, referring to Figures 5 to 8, the second rotating shaft 33 has a first cutting surface 331. A second cutting surface 3121 is formed on the inner surface of the second sleeve portion 312. The support member 40 has a storage state. In the storage state, the first limiting portion 51 and the second limiting portion 52 are in mutual contact, and an included angle is formed between the first cutting surface 331 and the second cutting surface 3121. The mutual contact between the first limiting portion 51 and the second limiting portion 52 in the storage state can prevent the support member 40 from shaking open and affecting the storage effect. By forming an included angle between the first cutting surface 331 and the second cutting surface 3121, a pre-tightening force can be provided between the second rotating shaft 33 and the second sleeve portion 312, and it can further prevent the second rotating shaft 33 and the second sleeve portion 312 from rotating without an external force applied. Moreover, during the process of the support member 40 from the storage state to the intermediate opening angle, the double-axis linkage member 31 and the support member 40 remain relatively stationary. Therefore, at any position between the storage state of the support member 40 and the intermediate opening angle, the effect of preventing shaking can be achieved through the setting of the included angle formed between the first cutting surface 331 and the second cutting surface 3121.
[0043] Specifically, referring to Figure 9 , in the storage state, the included angles between the first cutting surface 331 and the second cutting surface 3121 and the plane where the bracket storage area 11 is located are both obtuse angles, and the included angle between the first cutting surface 331 and the plane where the bracket storage area 11 is located is greater than the included angle between the second cutting surface 3121 and the plane where the bracket storage area 11 is located. As Figure 9 the center line L1 is a schematic diagram of a plane parallel to the plane where the bracket storage area 11 is located. In the orientation shown in Figure 9 , the bracket storage area 11 is located on the left side of the double-axis linkage member. Therefore, the included angles between the first cutting surface 331 and the second cutting surface 3121 and the plane where the bracket storage area 11 is located are viewed from the included angles they form with the left side of the line L1. To make the illustration clearer, Figure 9 in
[0044] the included angle formed between the extension line 331a of the first cutting surface 331 and the line L1 is represented by the angle A1, which represents the included angle between the first cutting surface 331 and the plane where the bracket storage area 11 is located, and the included angle formed between the extension line 3121a of the second cutting surface and the line L1 is represented by the angle A2, which represents the included angle between the second cutting surface 3121 and the plane where the bracket storage area 11 is located, and A1 is greater than A2. It can be called that a negative pressure angle is formed between the first cutting surface 331 and the second cutting surface 3121, and the effect of preventing the support member 40 from shaking open without an external force in the storage state can be achieved.
[0044] In some embodiments, a third cutting surface 321 is provided on the first rotating shaft 32, and a fourth cutting surface 3111 is formed on the inner surface of the first sleeve portion 311. An included angle is formed between the third cutting surface 321 and the fourth cutting surface 3111 in the storage state. Reference can be made to Figure 9, in some specific embodiments, in the storage state, the angle between the third cutting plane 321 and the plane where the bracket storage area 11 is located is an acute angle and less than the angle (acute angle) between the fourth cutting plane 3111 and the plane where the bracket storage area 11 is located. Figure 9 In Figure 9 , the angle between the third cutting plane 321 and the plane where the bracket storage area 11 is located is represented by the angle A3 between the extension line 321a of the third cutting plane 321 and the line L1, and the angle between the fourth cutting plane and the plane where the bracket storage area 11 is located is represented by the angle A4 between the extension line 3111a of the fourth cutting plane and the line L1, and A3 is less than A4. It can also be said that a negative pressure angle is formed between the third cutting plane 321 and the fourth cutting plane 3111. Similar to the principle of setting an angle between the first cutting plane 331 and the second cutting plane 3121, the setting of the angle between the third cutting plane 321 and the fourth cutting plane 3111 can make the rotation between the first rotating shaft 32 and the first shaft sleeve portion 311 more stable, and the double-axis linkage member 31 is less likely to shake with the base 20.
[0045] The above are only the preferred embodiments of the present invention, and do not impose any form of limitation on the present invention. Although the present invention has been disclosed above with the preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to equivalent embodiments by using the disclosed technical content within the scope of the technical solution of the present invention. However, as long as it does not depart from the content of the technical solution of the present invention, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
