[0024] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0025] In this application, the terms "upper," "inner," "outer," "middle," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are primarily for the purpose of better describing this application and its embodiments, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation.

[0026] Furthermore, in addition to indicating location or positional relationship, some of the aforementioned terms may also have other meanings. For example, the term "above" may also be used in some cases to indicate a certain dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0027] Furthermore, the terms "provided with" and "connected" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral structure; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0028] Furthermore, the terms "first," "second," etc., are primarily used to distinguish different devices, elements, or components (which may be the same or different in specific type and construction), and are not intended to indicate or imply the relative importance or quantity of the indicated devices, elements, or components. Unless otherwise stated, "a plurality of" means two or more.

[0029] Electronic device accessories, as extensions of electronic devices, can bring users more functions and enrich the user experience. Take phone cases as an example. By being placed on the phone, phone cases can provide a certain degree of protection. Furthermore, phone cases can also be equipped with stands, which can provide support when users are using their phones for applications such as watching videos and making video calls, thus freeing up the user's hands.

[0030] To provide the best user experience in both landscape and portrait modes, existing stands incorporate a rotation function to change the opening direction, thus meeting users' support needs in different orientations. Chinese patent CN219643959U discloses a stand protective shell that is rotatably connected to a back panel via a rotating structure, allowing for changes in the opening direction of the support. This rotating structure consists of a first rotating component and a second rotating component, located on opposite sides of the back panel and riveted together to clamp the back panel in the middle, enabling rotation of the rotating structure relative to the back panel. In this structure, because the first and second rotating components are riveted together, they cannot be removed from the back panel without damage, resulting in excessively high product repair costs and low component recycling rates.

[0031] To address the aforementioned technical problems, this application provides an electronic device accessory that uses a C-shaped connector to achieve a rotatable connection between the rotating connector and the accessory body. This enables the rotating connector and the accessory body to be detachable. Compared to the riveting method in the prior art, the detachable connection facilitates product disassembly and repair. Furthermore, the detachable connection does not damage the product's components, effectively improving the recycling rate of product components.

[0032] It is understandable that electronic device accessories can be, for example, protective cases, card holders, power banks, etc., and are connected to electronic devices to expand their functionality. This application uses a mobile phone protective case as an example of an electronic device accessory.

[0033] The technical solution of this application will be further described below with reference to the embodiments and accompanying drawings.

[0034] participate Figures 1-5This application provides a mobile phone protective case, including an accessory body 1, a rotating connector 2, a support 3, and a C-shaped connector 4. The surface of the accessory body 1 is provided with an interconnected mounting groove 11 and a storage groove 13, wherein the mounting groove 11 and the storage groove 13 are located at different positions on the outer surface of the accessory body 1, such as... Figure 2 As shown, the storage groove 13 is an annular groove on the outer surface, and the mounting groove 11 is located on one side of the storage groove 13 and communicates with it. The mounting groove 11 includes a groove bottom 11a and a groove sidewall 11b. A first slot 11c is provided on the groove sidewall 11b, which extends circumferentially along the mounting groove 11. In this embodiment, the first slot 11c is provided along a full circle of the groove sidewall 11b. The rotating connector 2 has an upper surface 2a, a lower surface 2b, and a side surface 2c located between the upper surface 2a and the lower surface 2b. The upper surface 2a is the surface of the rotating connector 2 away from the groove bottom 11a, and a second slot 21 is provided on the side surface 2c. The C-shaped connector 4 is simultaneously engaged in the first slot 11c and the second slot 21, so that the rotating connector 2 is installed in the mounting groove 11 and can rotate within the mounting groove 11 circumferentially. One end of the support member 3 is rotatably connected to the rotating connector 2, so that the other end of the support member 3 can be opened relative to the accessory body 1 or stored in the storage groove 13. When the other end of the support member 3 is stored in the storage groove 13, one end of the support member 3 overlaps the rotating connector 2, and the other end of the support member 3 is outside the rotating connector 2. That is, only a part of the support member 3 and the rotating connector 2 are overlapped together. In other words, the rotating connector 2 is relatively small overall, while the support member 3 is relatively large. The rotating connector 2 and the accessory body 1 are rotatably connected by the C-shaped connector 4, which realizes the detachability of the rotating connector 2 and the accessory body 1. Compared with the riveting solution in the prior art, the detachable connection is beneficial to the disassembly and repair of the product. On the other hand, the detachability will not damage the product parts, which can effectively improve the recycling rate of product parts.

[0035] Further reading Figure 6In some embodiments, the mobile phone case further includes a pivot 5, and the support member 3 includes a bushing portion that is rotatably connected to the pivot 5. The upper surface 2a of the rotating connector 2 is recessed downwards to provide a pivot receiving portion 22. The two opposite sidewalls of the pivot receiving portion 22 are respectively provided with a first shaft hole 22a and a second shaft hole 22b. The pivot 5 is located within the pivot receiving portion 22, and both ends of the pivot 5 are respectively inserted into the first shaft hole 22a and the second shaft hole 22b. In this embodiment, the pivot receiving portion 22 is a through hole provided on the rotating connector 2, penetrating the upper surface 2a and lower surface 2b of the rotating connector 2 along its thickness direction. In other embodiments, the pivot receiving portion 22 can also be a groove, i.e., on the lower surface 22b side, where the groove does not penetrate the lower surface 2b. Furthermore, in order to ensure that the rotating shaft 5 can be fixed relative to the rotating connector 2 after being inserted into the first shaft hole 22a and the second shaft hole 22b, that is, the rotating shaft 5 will not rotate in the first shaft hole 22a and the second shaft hole 22b, at least one plane can be cut out on the outer circumferential surface of the rotating shaft 5. Correspondingly, a corresponding number of planes are also provided on the inner surfaces of the first shaft hole 22a and the second shaft hole 22b. After the rotating shaft 5 is inserted into the first shaft hole 22a and the second shaft hole 22b, the planes face each other to restrict the rotation of the rotating shaft 5.

[0036] In some embodiments, continue reading Figure 6 The rotating connector 2 includes a connecting area 2d and a clearance area 2e. The connecting area 2d is disposed on the upper surface 2a. The rotating shaft receiving portion 22 is a through hole disposed in the connecting area 2d, and the through hole penetrates the connecting area 2d and the lower surface 2b. The clearance area 2e is recessed relative to the connecting area 2d towards the lower surface 2b, so that the clearance area 2e is lower than the connecting area 2d. Figure 1 It can be seen that when the support member 3 is stored, a part of the support member 3 is stacked on the clearance area 2e. Therefore, by reducing the height of the clearance area 2e, the clearance area 2e is lower than the connection area 2d. When the support member 3 is stored, the surface of the support member 3 is basically flush with the surface of the connection area 2d, and the support member 3 can be stored more flat.

[0037] In some embodiments, see Figure 6 and Figure 7The rotating connector 2 has a circular structure, which facilitates its rotation within the mounting groove 11. Both the first shaft hole 22a and the second shaft hole 22b extend radially along the rotating connector 2, and both penetrate the side surface 2c of the rotating connector 2. When inserting the rotating shaft 5, it can be inserted into the first shaft hole 22a and the second shaft hole 22b from the side of the rotating connector 22a penetrating the side surface 2c, or it can be inserted into the first shaft hole 22a and the second shaft hole 22b from the side of the rotating connector 22b penetrating the side surface 2c, making insertion of the rotating shaft 5 more convenient. Furthermore, the second slot 21 includes a first sub-slot 21a and a second sub-slot 21b. One end of the first sub-slot 21a communicates with the first shaft hole 22a, and the other end extends counterclockwise along the circumference of the rotating connector 2 to the second shaft hole 22b and communicates with the second shaft hole 22b. One end of the second sub-slot 21b communicates with the first shaft hole 22a, and the other end extends clockwise along the circumference of the rotating connector 2 to the second shaft hole 22b, where it communicates with the second shaft hole 22b. With this arrangement, compared to offsetting and disconnecting the second slot 21 from the first shaft hole 22a and the second shaft hole 22b, the above solution can reduce the thickness of the rotating connector 2 to a certain extent, which is more conducive to the thinning of the phone case. Furthermore, the communication between the second slot 21 and the first shaft hole 22a and the second shaft hole 22b does not affect the installation of the C-shaped connector 4 within the second slot 21, and the rotating connector 2 can rotate normally within the mounting groove 11 without affecting the installation of the rotating shaft 5.

[0038] For further details, please refer to [link / reference]. Figure 7 In some embodiments, the first sub-slot 21a and the second sub-slot 21b are at the same height on the side 2c of the rotating connector 2 to ensure that the C-shaped connector 4 can be properly engaged in the second slot 21. Simultaneously, the second slot 21 is closer to the lower surface 2b of the rotating connector 2 than either the first shaft hole 22a or the second shaft hole 22b. That is, in the thickness direction of the rotating connector 2, the second slot 21 is offset from the shaft hole; they are not at the same height. This offset arrangement ensures that the C-shaped connector 4 and the rotating shaft 5 do not interfere with each other, and their functions are not affected.

[0039] For further details, please refer to [link / reference]. Figure 6 and Figure 7 In some embodiments, the first sub-slot 21a has a first slot wall on the side near the lower surface 2b, and the second sub-slot 21b has a second slot wall on the side near the lower surface 2b. The first slot wall and the second slot wall are spaced apart at the first shaft hole 22a to form a first clearance notch 21c, and the first slot wall and the second slot wall are spaced apart at the second shaft hole 22b to form a second clearance notch 21d. The first clearance notch 21c and the second clearance notch 21d can form clearance when the rotating shaft 5 is inserted, which is more conducive to the installation and insertion of the rotating shaft 5.

[0040] In some embodiments, see Figure 3 The mounting groove 11 is a circular groove to fit the circular rotating connector 2. The first slot 11c is annular and is arranged around the side wall 11b of the groove. The side wall 11b of the groove is also provided with a notch 11d, which penetrates the side wall of the first slot 11c away from the bottom 11a of the mounting groove 11, and the notch 11d communicates with the first slot 11c. The rotating connector 2 is installed in the mounting slot 11 via the C-shaped connector 4. During installation, the C-shaped connector 4 is first secured in the second slot 21 on the side 2c of the rotating connector 2. External force is applied to cause the C-shaped connector 4 to elastically deform, retracting it into the second slot 21. The rotating connector 2 and the C-shaped connector 4 are then placed into the mounting slot 11. After the external force is removed, the C-shaped connector 4 returns to its original shape, extending into the first slot 11c, thus securing the rotating connector 2 in the mounting slot 11 and preventing it from detaching. When it is necessary to remove the rotating connector 2 from the mounting slot 11, tweezers or similar tools can be used to insert them into the first slot 11c through the notch 11d, pressing the C-shaped connector 4 to cause it to elastically deform and retract into the second slot 21. The rotating connector 2 can then be removed from the mounting slot 11. Therefore, setting the notch 11d facilitates the disassembly of the rotating connector 2, making it convenient for maintenance, parts disassembly and recycling, and other operations.

[0041] In some embodiments, see Figure 3 and Figure 4The accessory body 1 also includes a wear-resistant component 12, which is disposed within the mounting groove 11 and located between the rotating connector 2 and the groove bottom 11a. Further, the wear-resistant component 12 is attached to the groove bottom 11a of the mounting groove 11. Specifically, a fixing protrusion 11e protrudes from the groove bottom 11a, and a fixing part 12a is provided on the wear-resistant component 12. The fixing part 12a cooperates with the fixing protrusion 11e to restrict the movement of the wear-resistant component 12 relative to the groove bottom 11a. Due to limitations in bracket connection and strength, the rotating connector 2 is typically made of metal or alloy, while the accessory body 1 is made of plastic. If the rotating connector 2 rotates within the mounting groove 11, direct friction between the metal and plastic will cause wear to the groove bottom 11a of the mounting groove 11 within a short time. In severe cases, the groove bottom 11a may be worn through, causing the rotating connector 2 to contact the surface of the mobile phone, resulting in wear on the phone surface. Therefore, the above problems can be solved by setting the wear-resistant part 12. The wear-resistant part 12 is made of a friction-resistant and low-wear material such as silicone. Throughout the entire life cycle of the product, the wear-resistant part 12 will not disappear due to wear, ensuring the safety of the rotating connector 2 during rotation and preventing damage to the mobile phone. At the same time, by cooperating with the fixing part 12a and the fixing protrusion 11e to restrict the movement of the wear-resistant part 12 relative to the bottom of the groove 11a, the lifespan and function of the wear-resistant part 12 can be guaranteed not to be affected. Specifically, the fixing protrusion 11e can include multiple protrusions, all of which are connected to the side wall 11b of the groove and are spaced apart circumferentially along the side wall 11b of the groove. That is to say, the fixing protrusion 11e is set at the four edges of the bottom of the groove 11a, which can better limit the position of the wear-resistant part 12. The wear-resistant part 12 can be configured as an annular shape, and the fixing part 12a is a groove provided on the outer side of the annular part 12. The groove also includes multiple grooves and is arranged at intervals along the circumference of the wear-resistant part 12 to correspond one-to-one with the fixing protrusions 11e. The fixing protrusions 11e protrude into the groove to lock the wear-resistant part 12 and prevent it from moving relative to the bottom wall 11a. That is to say, when the rotating connector 2 rotates, it will not drive the wear-resistant part 12 to rotate. The wear-resistant part 12 and the bottom of the groove 11a are relatively fixed. Therefore, when the rotating connector 2 rotates, the friction between the wear-resistant part 12 and the bottom of the groove 11a is replaced by friction between the wear-resistant part 12.

[0042] In some embodiments, continue reading Figure 4 , Figures 9-11By setting the wear-resistant part 12 as a ring structure, a positioning groove 12b can also be set on the inner side of the ring of the wear-resistant part 12. At the same time, a receiving groove 23 is set on the lower surface 2b of the rotating connector 2. The receiving groove 23 includes a first sidewall 23a and a second sidewall 23b opposite to each other. The second sidewall 23b is closer to the side 2c of the rotating connector 2 than the first sidewall 23a. A positioning component 24 is also provided in the receiving groove 23. The positioning component 24 includes a positioning element 241, an elastic element 242 and a fixing shaft 243. The elastic element 242 is set in the receiving groove 23. One end of the elastic element 242 contacts the first sidewall 23a and the other end contacts the positioning element 241. The positioning element 241 includes a positioning part 241a. The positioning part 241a can extend into the positioning groove 12b. The fixing shaft 243 is sequentially passed through the second sidewall 23b, the positioning element 241 and the elastic element 242. When the rotating connector 2 rotates, the positioning component 24 rotates along with it. When it rotates to a specific position, the positioning part 241a extends into the positioning groove 12b. If the external force is removed at this point, a certain amount of external force is required for the positioning part 241a to disengage from the positioning groove 12b. Therefore, the rotating connector 2 can be kept at that angle. When the user applies external force to continue rotating the rotating connector 2, the positioning part 241a can disengage from the positioning groove 12b under the action of the elastic member 242, and the rotating connector 2 can continue to rotate. In some embodiments, multiple positioning grooves 12b can be provided on the inner side of the ring of the wear-resistant member 12 to achieve positioning of the rotating connector 2 at multiple different rotation angles.

[0043] Further reading Figure 12 In some embodiments, the positioning member 241 further includes a first main body portion 241b and a second main body portion 241c connected to each other. The first main body portion 241b is located within the receiving groove 23 and can move within the receiving groove 23. The second main body portion 241c protrudes from the second sidewall 23b. The positioning portion 241a is connected to the second main body portion 241c, and the positioning portion 241a extends protruding towards the sidewall 2c of the rotating connector 2 relative to the first main body portion 241b. In some embodiments, such as Figure 11 As shown, the lower surface 2b is recessed upwards with a guide groove 23c. The guide groove 23c extends through the second side wall 23b from the side 2c of the rotating connector 2. At least a portion of the positioning part 241a is located within the guide groove 23c and can move within it. By providing the receiving groove 23, a portion of the positioning member 241 (i.e., the first main body 241b) can be placed within the receiving groove 23, making the structure compact, while also providing space for the movement of the positioning member 241. The first main body 241b can move within the receiving groove 23 to drive the positioning part 241a to move within the guide groove 23c to extend into or disengage from the positioning groove 12b. The guide groove 23c serves both to limit the positioning part 241a and to guide it, preventing the 241a from shifting during movement.

[0044] For further details, please refer to [link / reference]. Figure 8 The rotating connector 2 has a mounting hole 25 on its side 2c, which penetrates the second side wall 23b from the side 2c. The first main body 241b has a U-shaped structure, and the bottom of the U-shaped structure has a positioning hole 241d that penetrates through it. The fixing shaft 243 passes through the mounting hole 25, the positioning hole 241d, and the elastic member 242 in sequence. During installation, the first main body 241b of the U-shaped structure can limit the elastic member 242, making it easier to install the positioning member 241 and the elastic member 242 into the receiving groove 23. Then, the fixing shaft 243 passes through the mounting hole 25, the positioning hole 241d on the positioning member 241, and the elastic member 242 in sequence to fix the positioning member 241 and the elastic member 242 in the receiving groove 23 and prevent them from falling out of the receiving groove 23.
