Description

Technical Field

[0001] This application relates to the technical field of peripheral accessories for electronic products, and particularly to an electronic device accessory. Background Technology

[0002] Users typically protect their phones with phone cases. Besides protection, phone cases often offer additional functions such as stands and wrist straps. With the continuous development of smartphones, watching long videos in landscape mode and scrolling through short videos in portrait mode has become an indispensable part of users' lives. In these scenarios, phone stands have brought great convenience, supporting the phone, freeing up users' hands, and preventing fatigue and discomfort from prolonged phone use. However, this also presents significant challenges to the design of phone stands.

[0003] In existing technologies, to enable the stand to support both horizontal and vertical screens, it is typically connected to the protective shell via a rotating connection structure. This connection structure is attached to the shell using methods such as snap-fitting or clamping, allowing relative rotation between the stand and the shell. While this connection structure allows for both horizontal and vertical screen support, it also introduces several problems. During rotation, the connection structure rubs against the protective shell, and prolonged rotation can wear down the shell, leading to damage, stand detachment, and a shortened lifespan. Users then need to frequently replace the protective shell to meet their needs, increasing operating costs.

[0004] Therefore, it is necessary to improve the structure of existing electronic device components to solve the above problems. Summary of the Invention

[0029] Before describing the embodiments in detail, it should be understood that this application is not limited to the detailed structures or element arrangements described below or in the accompanying drawings. This application can be implemented in other ways. Furthermore, it should be understood that the wording and terminology used herein are for descriptive purposes only and should not be construed as limiting. The terms "comprising," "including," "having," and similar expressions used herein mean to include the items listed thereafter, their equivalents, and other additional items. In particular, when describing "an element," this application does not limit the number of elements to one, but may include multiple elements.

[0030] Please also refer to Figures 1 to 9 As shown, this application provides an electronic device accessory 10, which includes a main body 12, a support 14, and a rotating structure. The rotating structure includes a first component 16 and a second component 18. The support 14 is rotatably connected to the first component 16, and the first component 16 and the second component 18 are rotatably connected via a connecting structure, allowing the support 14 to rotate 360° relative to the main body 12 to adjust the support direction. The second component 18 is disposed on the main body 12 and is fixed relative to the main body 12 in the rotation direction of the first component 16. This application proposes a novel rotating structure that replaces the rotation between the existing connecting structure and the main body with the rotation between the first component 16 and the second component 18, avoiding rotation occurring on the main body 12. This effectively solves the problem of wear on the protective shell caused by the rotation of the connecting structure in the prior art, extends the service life of the main body 12 of the electronic device accessory 10, and reduces the product's operating cost.

[0031] In existing technologies, electronic device components, limited by their function and structure, generally require high-strength metals or alloys for their connection structures to ensure stable connections. Protective shells, on the other hand, are typically made of plastics such as PC or TPU. When the high-strength metal or alloy material rotates with the plastic material, the plastic is easily worn down, leading to damage to the protective shell. In this application, by improving the rotating structure, both the first component 16 and the second component 18 can be made of materials with good wear resistance, such as manganese steel. When they rotate relative to each other, wear is minimal, effectively improving the overall wear resistance of the rotating structure and thus significantly extending the service life of the electronic device component 10. Furthermore, since the second component 18 does not rotate with the main body 12, it effectively protects the main body 12 from wear.

[0032] In the illustrated embodiments, please also refer to Figure 1 , Figure 2 and Figure 4 As shown, the main body 12 includes an accessory body 20 and a mounting base 22. The mounting base 22 is fixedly mounted on the accessory body 20, and the second component 18 is disposed on the mounting base 22, and the second component 18 is fixed relative to the mounting base 22 in the rotational direction of the first component 16. In some embodiments, the main body 12 may not have a mounting base 22, and the main body 12 may only include the accessory body 20. The second component 18 may be directly disposed on the accessory body 20, and the second component 18 is fixed relative to the accessory body 20 in the rotational direction of the first component 16.

[0033] In this application, the accessory body 20 can be a protective case, power bank, charger, or card holder, etc. In this embodiment, the accessory body 20 is a protective case, specifically, as shown in the example below. Figure 4 As shown, the accessory body 20 includes a back plate 24 and side frames 26 connected to the periphery of the back plate 24. The back plate 24 and the side frames 26 together form a receiving cavity 28 for accommodating an electronic device, such as a mobile phone or tablet computer. The mounting base 22 is fixedly mounted on the back of the back plate 24. Preferably, the back plate 24 has a lens clearance hole 30 corresponding to the lens of the electronic device. After the electronic device is installed in the receiving cavity 28, the lens of the electronic device protrudes from the lens clearance hole 30. The mounting base 22 can be a lens protection frame, for example, the mounting base 22 is fixedly clamped on the edge of the lens clearance hole 30.

[0034] Optionally, both the bracket 14 and the mounting base 22 are rectangular. In other embodiments, the bracket 14 and the mounting base 22 can also be designed in other shapes, and the mounting base 22 can also be fixedly installed on other parts of the back plate 24. Figure 1 and Figure 2As shown, the second component 18 is disposed on the side of the mounting base 22 away from the receiving cavity 28. For example, the second component 18 is disposed on the top side of the mounting base 22 near the back plate 24 and in the center corner. The bracket 14 is rotatably connected to the second component 18 through the first component 16.

[0035] Please also refer to Figure 2 and Figure 3 As shown, the bracket 14 can rotate relative to the main body 12 about a first axis a, and the first component 16 can rotate relative to the main body 12 about a second axis b. Preferably, the first axis a is parallel to the back plate 24, and the second axis b is perpendicular to the back plate 24. The bracket 14 can rotate relative to the mounting base 22 between a storage position and a support position. In the storage position, the bracket 14 is stacked on the mounting base 22 and can also serve as a lens protection frame, maintaining the product's aesthetics while protecting the lens. In the support position, the bracket 14 rotates away from the mounting base 22 and forms a support angle with the mounting base 22, which can be used to support the main body 12 and the electronic device mounted on the main body 12. Furthermore, the bracket 14 can rotate 360° relative to the mounting base 22 through the first component 16, thereby adjusting the support angle of the bracket 14 as needed, for example, to achieve horizontal or vertical screen support for the electronic device.

[0036] Preferably, when the bracket 14 is opened, a portion of the bracket 14 extends beyond the accessory body 20. The extended portion can serve as a suspension structure, and can be connected to the suspension structure using a hanging rope to achieve the suspension function, thereby increasing the usage scenarios and functions of the electronic device accessory 10.

[0037] In the illustrated embodiments, please also refer to Figures 5 to 7 As shown, both the first component 16 and the second component 18 are cylindrical structures. Preferably, the diameters of the first component 16 and the second component 18 are both set within the range of 5mm to 8mm. If the dimensions of the first component 16 and the second component 18 are too small, it will not be sufficient to ensure the connection strength; if they are too large, it will affect the overall appearance of the bracket 14 and make the overall volume of the bracket 14 too large and bulky. The bracket 14 has a pivot position 32 at the corner position corresponding to the first component 16. The pivot position 32 is, for example, a notch structure. The first component 16 is located at the pivot position 32 and is rotatably connected to the bracket 14 through a rotating shaft 34. Specifically, the first component 16 has a shaft hole 36, for example, the shaft hole 36 is set off from the center of the first component 16. The opposite side walls of the pivot position 32 are respectively provided with connecting holes 38. The rotating shaft 34 is rotatably inserted through the shaft hole 36, and the two ends of the rotating shaft 34 are respectively fixedly connected to the corresponding connecting holes 38, thereby realizing the rotatable connection between the bracket 14 and the first component 16. It should be understood that, in other embodiments, the bracket 14 and the first component 16 may also be rotatably connected by other rotating structures.

[0038] The first component 16 and the second component 18 are rotatably connected by a connecting structure. When they rotate relative to each other, without restriction, the support 14 may rotate due to the weight of the electronic device or external forces, affecting the support stability of the support 14. In this embodiment, as... Figures 6 to 9 As shown, the connection structure includes a first toothed structure 40 disposed on the side of the first component 16 facing the second component 18 and a second toothed structure 42 disposed on the side of the second component 18 facing the first component 16. The first toothed structure 40 and the second toothed structure 42 are rotatably meshed with each other, so that after the first component 16 rotates at a certain angle, it can be stabilized at that angle through the meshing of the toothed structures, thereby improving the support stability of the bracket 14.

[0039] Specifically, the first tooth-like structure 40 is disposed on the side of the first member 16 facing the second member 18, and the second tooth-like structure 42 is disposed on the side of the second member 18 facing the first member 16. The first tooth-like structure 40 includes a plurality of first teeth 44, which are trapezoidal in shape. The plurality of first teeth 44 are evenly spaced along the circumference of the first member 16. The first teeth 44 extend in the radial direction of the first member 16. The two opposite circumferential side surfaces 46 of the first teeth 44 are inclined towards each other in the direction facing the second member 18, that is, the size of the first teeth 44 gradually decreases in the extension direction from the first member 16 to the second member 18. Furthermore, the first tooth 44 has an outer surface 441 on the side away from the central axis of the first member 16 and an inner surface 442 on the side closer to the central axis of the first member 16. The area of ​​the outer surface 441 of the first tooth 44 is larger than the area of ​​the inner surface 442 of the first tooth 44. The outer surface 441 is the outer surface of the first tooth 44 in the radial direction of the first member 16, and the inner surface 442 is the inner surface of the first tooth 44 in the radial direction of the first member 16. For example, the size of the first tooth 44 gradually decreases in the radially inward direction. Preferably, the circumferential side 46 of the first tooth 44 is an inclined and curved surface to increase the smoothness of rotation of the tooth structure. In this embodiment, "multiple" refers to two or more; in other embodiments, only one first tooth 44 may be provided.

[0040] The second tooth structure 42 is shaped to match the first tooth structure 40. Specifically, the second tooth structure 42 includes a plurality of second teeth 48, which are trapezoidal in shape. The plurality of second teeth 48 are evenly spaced along the circumference of the second member 18. The second teeth 48 extend in the radial direction of the second member 18. The two opposite circumferential side surfaces 50 of the second teeth 48 are inclined towards each other in the direction toward the first member 16, that is, the size of the second teeth 48 gradually decreases in the direction of extension from the second member 18 toward the first member 16. Furthermore, the second tooth 48 has an outer surface 481 on the side away from the central axis of the second member 18 and an inner surface 482 on the side closer to the central axis of the second member 18. The area of ​​the outer surface 481 of the second tooth 48 is larger than the area of ​​the inner surface 482 of the second tooth 48. The outer surface 481 is the outer surface of the second tooth 48 in the radial direction of the second member 18, and the inner surface 482 is the inner surface of the second tooth 48 in the radial direction of the second member 18. For example, the size of the second tooth 48 gradually decreases in the radially inward direction. Preferably, the circumferential side surface 50 of the second tooth 48 is an inclined and curved surface, and the circumferential side surface 46 of the first tooth 44 fits snugly against the circumferential side surface 50 of the second tooth 48 to increase the smoothness of rotation of the tooth structure. In this embodiment, "multiple" refers to two or more; in other embodiments, only one second tooth 48 may be provided.

[0041] By providing inclined surfaces on both sides of the first tooth 44 and the second tooth 48 in the circumferential direction, the first component 16 is more likely to rotate when subjected to force, and the rotation between the first component 16 and the second component 18 will not be restricted after the teeth mesh. Ultimately, the first component 16 can only rotate relative to the second component 18 under a certain external force, and the first component 16 can be stably fixed at the angle after rotation.

[0042] When the first toothed structure 40 and the second toothed structure 42 mesh with each other, the first tooth 44 is just accommodated in the space between two adjacent second toothed sections 48, and the second toothed section 48 is just accommodated in the space between two adjacent first toothed sections 44. During the rotation of the first member 16 relative to the second member 18, due to the circumferential fixation of the second member 18 and the interaction force between the first toothed structure 40 and the second toothed structure 42, the second member 18 moves up and down in a piston-like manner relative to the first member 16.

[0043] Compared to existing hinge structures, the first component 16 and the second component 18 used in this application are both cam structures, which increases the thickness and consequently increases the thickness of the rotating structure. In this embodiment, the mounting base 22 has a receiving portion 52 on the side facing the first component 16. The receiving portion 52 is, for example, a groove structure. The second component 18 is at least partially received within the receiving portion 52, thereby reducing the thickness of the rotating structure and thus reducing the overall thickness of the electronic device accessory 10. It should be noted that in some embodiments, the electronic device accessory 10 does not have a mounting base 22, and the receiving portion 52 can be provided on the accessory body 20, with the second component 18 at least partially received within the receiving portion 52.

[0044] When the first component 16 rotates, the first toothed structure 40 pushes open the second toothed structure 42, causing the second component 18 to move downwards. In order for the second component 18 to reset and resume engagement with the first component 16, in this embodiment, an elastic element 54 is provided between the bottom surface of the second component 18 and the bottom wall of the groove of the receiving portion 52. The elastic element 54 is, for example, a spring. The elastic element 54 continuously applies an elastic bias to the second component 18, causing it to move toward the first component 16. When the first component 16 and the second component 18 are engaged, the elastic element 54 is in its initial state; when the first component 16 rotates relative to the second component 18, the interaction between the first toothed structure 40 and the second toothed structure 42 drives the second component 18 to move away from the first component 16, and the elastic element 54 is in a compressed state. Specifically, when the first component 16 rotates, it generates a downward rotational force on the second component 18. Since the second component 18 is circumferentially fixed, the circumferential component of the rotational force is canceled out. The downward component of the rotational force overcomes the upward elastic force of the elastic member 54, causing the second component 18 to move downward. The elastic member 54 is compressed and continues to rotate, causing the first tooth 44 and the second tooth 48 to misalign. After misalignment, the second component 18 returns to its original position under the upward elastic force of the elastic member 54, allowing the first tooth structure 40 and the second tooth structure 42 to mesh again. Preferably, the elastic force of the elastic member 54 is controlled between 10N and 30N. This elastic force allows the tooth structures of the first component 16 and the second component 18 to mesh tightly together, preventing loosening, while not affecting the rotation of the first component 16. If the elastic force of the elastic element 54 is too small, the first component 16 and the second component 18 will become loose, affecting the support stability of the bracket 14; if the elastic force of the elastic element 54 is too large, the first component 16 and the second component 18 will mesh too tightly, affecting their mutual rotation.

[0045] In the illustrated embodiment, as Figure 6 and Figure 7As shown, the receiving portion 52 is provided with a first sliding limiting portion 56, which extends along the depth direction of the receiving portion 52, which is the groove depth direction of the receiving portion 52. The second component 18 is provided with a second sliding limiting portion 58, which extends along the height direction of the second component 18, which is the axial direction of the second component 18. The first sliding limiting portion 56 and the second sliding limiting portion 58 are in concave-convex fit and slidably connected, thereby realizing the circumferential limiting of the second component 18 without affecting the vertical movement of the second component 18. Preferably, the first sliding limiting part 56 is a slide rail disposed on the inner wall of the receiving part 52. Multiple slide rails can be provided, each extending along the direction of the second axis b and evenly spaced in the circumferential direction. Correspondingly, the second sliding limiting part 58 is a plurality of slide rails disposed on the outer wall of the second member 18. Each slide rail is slidably disposed within its corresponding slide rail, thereby limiting the second member 18 in the circumferential direction, ensuring that the second member 18 can only move up and down in a piston-like manner along the direction of the second axis b, and cannot rotate. In other embodiments, the first sliding limiting part 56 can also be a slide rail, and the second sliding limiting part 58 can be a slide rail.

[0046] Furthermore, an anti-detachment structure is provided between the first component 16 and the mounting base 22. The anti-detachment structure is used to axially limit the first component 16 in the direction of the second axis b, so as to prevent the first component 16, the second component 18 and the bracket 14 from detaching from the mounting base 22. In this embodiment, the anti-detachment structure is a limiting rod 60. The second component 18 is provided with a through hole 62, which is provided, for example, at the center of the second component 18. The bottom center of the first component 16 is provided with a rotation limiting hole, and the bottom center of the receiving part 52 is provided with a fixing hole 64. The limiting rod 60 passes through the through hole 62, and the upper end of the limiting rod 60 is rotatably connected to the rotation limiting hole, while the lower end of the limiting rod 60 is fixedly connected to the fixing hole 64. For example, the upper end of the limiting rod 60 is provided with an enlarged part, and the rotation limiting hole is provided with a limiting groove for receiving the enlarged part. The limiting effect between the enlarged part and the limiting groove allows the first component 16 to rotate relative to the limiting rod 60 but not to move up and down in the direction of the second axis b. The second component 18 can move up and down relative to the limiting rod 60 through the through hole 62. The limiting rod 60 serves to guide the up and down movement of the second component 18 and to restrict the circumferential movement of the second component 18, preventing the second component 18 from detaching from the mounting base 22.

[0047] In other embodiments, the anti-detachment structure may also be provided between the first component 16 and the second component 18 and between the second component 18 and the mounting base 22, which can also limit the first component 16 and the second component 18 without affecting the rotation of the first component 16 and the up-down movement of the second component 18, thus preventing them from detaching from the mounting base 22.

[0048] In the illustrated embodiment, when the bracket 14 is in the retracted position, a notch 100 is provided at the end of the bracket 14 corresponding to the pivot position 32 and close to the main body 12. The notch 100 forms a step, which can prevent interference between the end of the bracket 14 and the mounting base 22 or accessory body 20 when the bracket 14 is opened. When the bracket 14 is in the retracted position, the side of the first component 16 facing away from the second component 18 is lower than or flush with the side of the bracket 14 away from the main body 12. This arrangement can effectively avoid problems such as the rotating structure protruding from the bracket 14 scratching other items or scratching the user when the electronic device accessory 10 and its assembled electronic device are placed in a bag or pocket. The ends of the opposite side walls of the pivot position 32 are curved surfaces 102. For example, if the opposite ends of the side walls of the pivot position 32 are both curved surfaces 102, it can effectively prevent scratches or damage to the main body 12 during use. If the ends of the opposite side walls of the pivot position 32 are too sharp, it is dangerous during use and can easily scratch the main body 12.

[0049] In summary, this application provides an electronic device accessory, including a main body, a bracket, and a rotating structure. The rotating structure includes a first component and a second component, which are rotatably connected via a connecting structure. The bracket is rotatably connected to the first component, and the second component is disposed on the main body and fixed relative to the main body in the rotation direction of the first component. This application proposes a novel rotating structure that replaces the rotation between the existing connecting structure and the main body with the rotation between the first and second components, avoiding rotation occurring on the main body.
