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. The bracket and the outer shell or protective case of the electronic device are rotatably connected by a hinge. When the support function is not needed, the bracket is stored on the back of the outer shell or protective case. At this time, the rotation angle of the bracket is considered to be 0°. When the support function is needed, the bracket can be flipped to a certain angle. However, the single-axis design of the existing bracket causes interference between the bracket and the outer shell or protective case during the rotation of the bracket, and the rotation angle is limited to about 0 to 110°, which cannot meet the demand for support at a larger angle.

It should be understood that the terms used in this way are interchangeable where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or are inherent to these processes, methods, products or devices.

[0031] It should also be noted that the division of multiple embodiments in the present invention is only for the convenience of description and should not constitute a special limitation. The features in various embodiments can be combined and referenced to each other without contradiction.

[0032] Reference Figure 1 The present invention provides an electronic device accessory, including a fixing member 10, a rotating shaft assembly 20 and a bracket 30. Figure 2 and Figure 3 The shaft assembly 20 includes a shaft connector 21, which is rotatably connected to the fixing member 10. The bracket 30 is rotatably connected to the end of the shaft connector 21 away from the fixing member 10. The bracket 30 can be rotated relative to the fixing member 10 by the shaft connector 21 in the first position ( Figure 1 shown) and the second position ( Figure 2 And the bracket 30 can be rotated in the second position ( Figure 2 、 Figure 4 shown) and the third position ( Figure 5 、 Figure 6The rotation angle between the bracket 30 and the fixing member 10 increases in sequence according to the first position, the second position and the third position.

[0033] The rotation angle between the bracket 30 and the fixing member 10 (hereinafter referred to as the rotation angle of the bracket 30) is the angle at which the bracket 30 is opened. The electronic device accessory may be, for example, a protective case with a bracket or a mobile power bank with a bracket. The electronic device accessory may further include a housing 70, which may be a protective case or a housing of a mobile power bank. Figure 1 The following uses a protective case with a stand as an example. The housing 70 includes a back panel 71 and side frames 72. The back panel 71 and side frames 72 together form a housing cavity. When the housing 70 is mounted on an electronic device such as a mobile phone, the electronic device is located within the housing cavity. When the support function is not needed, the stand 30 can be stored on the back of the back panel 71, away from the housing cavity. In this case, the stand 30 is in the closed state. The rotation angle of the stand 30 can be determined based on the back of the back panel 71 and the surface of the stand 30 that contacts the back of the stand 30 in the closed state (which can be referred to as the inner surface of the stand 30). In the closed state, the rotation angle of the stand 30 is 0°. As the stand 30 is gradually opened, the rotation angle of the stand 30 gradually increases. The first position is, for example, the position of the stand 30 in the closed state, that is, the rotation angle of the stand 30 in the first position is 0°. The third position is, for example, the position of the stand 30 when it is fully opened. In the third position, the rotation angle of the stand 30 is 180°, and the inner surface of the stand 30 faces away from the back panel 71. The second position is between the first position and the third position. When the bracket 30 is in the second position, the angle between the bracket 30 and the fixing member 10 is, for example, 80 to 100°. Specifically, when the bracket 30 is in the second position, the angle between the bracket 30 and the fixing member 10 is 90°.

[0034] Reference Figure 4 The electronic device accessory further includes a stopper 51 and an auxiliary rotating member 40. The stopper 51 is disposed on the rotating shaft connector 21. When the bracket 30 is in the second position, the stopper 51 limits the position of the rotating shaft connector 21 and the fixing member 10. The auxiliary rotating member 40 is connected to the bracket 30. When the bracket 30 rotates from the second position to the first position, the auxiliary rotating member 40 drives the rotating shaft connector 21 to rotate relative to the fixing member 10.

[0035] The electronic device accessory provided by the present invention has the following working principle: with the bracket 30 in the first position as the initial state, when opening the bracket 30, the bracket 30 and the rotating shaft connector 21 are first relatively stationary and rotate synchronously with respect to the fixed part 10. When the bracket 30 rotates to the second position, the rotating shaft connector 21 is limited by the fixing part 10 through the limiter 51. If the bracket 30 needs to be further opened, the rotating shaft connector 21 and the fixed part 10 are relatively stationary, and the bracket 30 rotates around the rotating shaft connector 21 to reach the third position. When the bracket 30 needs to be gradually closed from the third position, the rotating shaft connector 21 and the fixed part 10 are first relatively stationary under the action of the limiter 51, and the bracket 30 rotates back to the second position around the rotating shaft connector 21. If the bracket 30 needs to be further closed, the limit between the rotating shaft connector 21 and the fixed part 10 is released under the drive of the auxiliary rotating member 40, and the rotating shaft connector 21 and the bracket 30 rotate synchronously to finally reach the first position.

[0036] In this embodiment, the bracket 30 is rotated in sections using the rotating shaft connector 21, which prevents interference between the bracket 30 and the fixing member 10 or the housing 70. This allows the bracket 30 to open at a maximum angle of 180°, accommodating a wider range of support angles. Furthermore, the stopper 51 and the auxiliary rotating member 40 facilitate smoother, more convenient operation of the bracket 30's two-section rotation process.

[0037] In some embodiments, continue to refer to Figure 4 Specifically, a first sleeve 211 is provided at one end of the rotating shaft connector 21 connected to the fixed member 10, and a second sleeve 212 is provided at one end of the rotating shaft connector 21 connected to the bracket 30. The rotating shaft assembly 20 also includes a first rotating shaft 22 and a second rotating shaft 23. The first rotating shaft 22 is inserted through the first sleeve 211 and is rotatably connected to the rotating shaft connector 21. The fixed member 10 is fixed to the first rotating shaft 22. The second rotating shaft 23 is inserted through the second sleeve 212 and is rotatably connected to the rotating shaft connector 21; the bracket 30 is fixed to the second rotating shaft 23. The ends of the rotating shaft connector 21 are formed with first and second sleeves 211, 212, each having an opening, for example, by rolling. With the first rotating shaft 22 rotatably connected to the first sleeve 211 and the second rotating shaft 23 rotatably connected to the second sleeve 212, the first sleeve 211 and the second sleeve 212 can provide damping force for the first and second rotating shafts 22 and 23, respectively, ensuring that the bracket 30 can maintain a stable angle of support.

[0038] In some embodiments, the damping force between the first rotating shaft 22 and the first shaft sleeve 211 is less than the damping force between the second rotating shaft 23 and the second shaft sleeve 212. The damping force between the first rotating shaft 22 and the first shaft sleeve 211 refers to the frictional force between the first rotating shaft 22 and the first shaft sleeve 211 when the two rotate relative to each other, and the damping force between the second rotating shaft 23 and the second shaft sleeve 212 refers to the frictional force between the second rotating shaft 23 and the second shaft sleeve 212 when the two rotate relative to each other. This configuration allows the bracket 30 to first overcome the damping force between the first rotating shaft 22 and the first shaft sleeve 211 during rotation from the first position to the second position. Since the damping force between the second rotating shaft 23 and the second shaft sleeve 212 is greater, the bracket 30 remains relatively stationary, allowing the bracket 30 to rotate synchronously with the shaft connector 21 relative to the fixed member 10.

[0039] Specifically, in some embodiments, reference may be made to Figure 8 One specific embodiment of achieving a damping force between the first rotating shaft 22 and the first sleeve 211 that is smaller than the damping force between the second rotating shaft 23 and the second sleeve 212 is that the wall thickness D1 of the first sleeve 211 is smaller than the wall thickness D2 of the second sleeve 212. More specifically, the difference in wall thickness between the second sleeve 212 and the first sleeve 211 ranges from 0.05 to 2 mm.

[0040] In some embodiments, reference Figure 5 , the limiting member 51 is a protrusion provided on the first sleeve 211, and a groove 52 matching the protrusion is provided on the fixing member 10. In other embodiments, the limiting member 51 may be a groove 52 provided on the first sleeve 211, and a protrusion matching the groove 52 is provided on the fixing member 10. The protrusion is, for example, a strip-shaped protrusion extending axially along the first rotating shaft 22, and the surface of the protrusion is arc-shaped. The shape of the groove 52 matches the shape of the protrusion, and can be an arc-shaped groove extending axially along the first rotating shaft 22. In some embodiments, the fixing member 10 is, for example, provided with a receiving groove for accommodating the rotating shaft assembly 20, wherein the groove or protrusion matching the limiting member 51 can be provided at the bottom of the receiving groove or on the side wall of the receiving groove close to the second sleeve 212.

[0041] In some embodiments, a first blocking position is provided on the rotating shaft connecting member 21. When the bracket 30 is in the second position, the auxiliary rotating member 40 contacts the first blocking position. When the bracket 30 rotates from the second position to the first position, the auxiliary rotating member 40 pushes the rotating shaft connecting member 21 to rotate relative to the fixed member 10. For example, a protrusion 24 is formed on the second sleeve 212, and the surface of the protrusion 24 facing the auxiliary rotating member 40 forms a first blocking position. The protrusion 24 can be, for example, a rib provided on the outer surface of the second sleeve 212, and the auxiliary rotating member 40 can be, for example, integrally formed with the bracket 30 or connected to the bracket 30. For example, referring to Figure 4The electronic device accessories also include a bracket connector 60, which is riveted to the bracket 30 and has an axial hole. Both ends of the second rotating shaft 23 are passed through the axial holes of the bracket connector 60 to be fixed to the bracket 30. The auxiliary rotating member 40 can also be a rib formed on the bracket connector 60 and extending in the direction close to the protrusion 24. In the process of the bracket 30 rotating from the third position to the second position, the auxiliary rotating member 40 gradually approaches the protrusion 24. When the bracket 30 rotates to the second position, the auxiliary rotating member 40 abuts against the protrusion 24. If the bracket 30 continues to be closed, the auxiliary rotating member 40 will rotate with the bracket 30 and generate a thrust on the protrusion 24, which can drive the shaft connector 21 to rotate synchronously, so as to synchronously store the shaft connector 21 and the bracket 30.

[0042] In some embodiments, the shaft connector 21 is further provided with a second blocking position, the first blocking position and the second blocking position are spaced apart along the circumference of the second shaft 23, and the auxiliary rotating member 40 is located between the first blocking position and the second blocking position. Figure 7 and Figure 8 The second sleeve 212 is provided with a slot 25. The slot 25 has a first sidewall 251 and a second sidewall 252 that are opposite to each other along the circumference of the second rotating shaft 23. The first blocking position includes the first sidewall 251, and the second blocking position includes the second sidewall 252. The auxiliary rotating member 40 can be connected to the bracket connector 60. The provision of the slot 25 on the second sleeve 212 allows the bracket 30 and the rotating shaft connector 21 to be linked by the cooperation between the auxiliary rotating member 40 and the first and second sidewalls 251 and 252. The slot 25 also simplifies manufacturing and reduces the processing difficulty.

[0043] In some embodiments, the slot 25 is located on the end of the second sleeve 212 along the axial direction of the second rotating shaft 23. Figure 7 As shown, two axial ends of the second sleeve 212 along the second rotating shaft 23 are respectively provided with slots 25 , and auxiliary rotating parts 40 are also respectively provided corresponding to the two slots 25 , so that the force is more balanced.

[0044] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment, it is not intended to limit the present invention. Any technician familiar with the profession can make some changes or modifications to equivalent embodiments of the technical content disclosed above without departing from the scope of the technical solution of the present invention. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
