[0002] With the continuous development of technology, people use various electronic devices to facilitate daily life and work. These devices typically require cables for charging or data transfer. Current technologies increasingly employ retractable modules to wind up the cables, allowing users to extend them to the appropriate length as needed, or automatically rewind and store them after use, thus meeting the diverse needs of different user scenarios.

[0003] Taking power strips as an example, people often use power strips to connect electronic devices and mains power over long distances. However, when not in use, the long connecting cords on power strips are not easy to store, making them inconvenient to carry.

[0069] Furthermore, the terms "embodiment," "implementation," "example," etc., used herein refer to specific features, structures, or characteristics described in connection with an embodiment that may be included in at least one embodiment of this utility model. These phrases appearing in various places throughout the specification do not necessarily refer to the same embodiment, nor are they independent or alternative embodiments mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0070] This utility model provides an electronic device accessory 100, which includes, but is not limited to, power strips, power banks, data cables, chargers, etc., and can be used in 3C products that require power supply or data transmission.

[0071] like Figures 1 to 4 As shown, the electronic device accessory 100 includes a housing, a telescopic module 2, and a connecting shaft 5. The housing includes a first housing 1 and a second housing 6, one of which is a top cover, and the other is a bottom cover. For example, as... Figure 4 As shown, the first housing 1 is the bottom cover 1, and the second housing 6 is the top cover 6, or the first housing is the top cover and the second housing is the bottom cover.

[0072] In this embodiment, the first housing 1 and the second housing 6 are fitted together, and together they form a cavity 7. An installation area 11 is defined within the cavity 7. It should be noted that the installation area 11 is primarily used for installing the telescopic module 2, while other areas can be used for installing other components.

[0073] To simplify the overall structure and make it more compact, the connecting shaft 5 is disposed on or abuts against the outer shell along the height direction of the first housing 1 within the mounting area 11. Understandably, the connecting shaft 5 extends along the height direction of the first housing 1 and is located within the cavity 7.

[0074] In this embodiment, the telescopic module 2 is mounted on the outer shell within the cavity 7 via a connecting shaft 5. By directly mounting the telescopic module 2 within the outer shell via the connecting shaft, compared to existing telescopic modules with upper and lower covers, at least the lower cover is eliminated. This reduces the space occupied by the telescopic module 2 within the cavity 7, thereby reducing the overall thickness of the outer shell and facilitating the ultra-thin design of the electronic device accessory 100. In this embodiment, the telescopic module 2 includes a wire telescopic component, which includes a connecting wire 22. The wire telescopic component is rotatably sleeved on the connecting shaft 5 and configured to extend or shorten the portion of the connecting wire 22 extending beyond the outer shell. Understandably, the telescopic module 2 can be used to extend and retract the connecting wire 22, allowing for convenient connection to an external power source or connection port within a target range after extending a preset length, to meet long-distance charging or signal transmission needs. Of course, when not in use, the connecting wire 22 can be automatically retracted for storage.

[0075] For example, one end of the connecting wire 22 (i.e., the connecting end 221) is disposed inside the housing, and the other end (i.e., the external end 222) extends out of the housing. When the other end of the connecting wire 22 is stretched outside the housing, the wire telescopic component can rotate relative to the connecting shaft 5 to ensure that its connecting wire 22 extends to a preset length as needed. When the connecting wire 22 needs to shorten the extension length or restore the original extension length after extending to the preset length, the wire telescopic component can also rotate in the opposite direction relative to the connecting shaft 5 to ensure that its connecting wire 22 automatically retracts.

[0076] It should be noted that the connecting cable 22 mentioned in this article includes, but is not limited to, power cords, data cables, etc. The cross-sectional shape of the connecting cable 22 can be at least one of a circle, a square, or a rectangle. Taking a power cord with a rectangular cross-section as an example, this type of power cord (i.e., a flat power cord) improves the stability of the connecting cable 22 during coiling, reducing the risk of slippage and thus enhancing the stability of its extension and retraction. Furthermore, compared to round power cords, flat power cords are generally more aesthetically pleasing, less prone to tangling, suitable for applications requiring coiling, and easy to store and carry.

[0077] It should also be noted that the other end of the connecting cable 22 (i.e., the external end 222) can be connected to connectors including, but not limited to, USB-A connectors, TYPE-C connectors, Lightning connectors, or multi-in-one connectors. No specific limitations are made here; the choice can be made based on actual needs.

[0078] In summary, compared with the prior art, this electronic device accessory 100 has at least the following beneficial effects:

[0079] The electronic device accessory 100 facilitates the extension or shortening of the connecting wire 22 extending out of the housing by directly setting a connecting shaft 5 extending along the height direction of the first housing 1 in the mounting area 11 inside the housing, and rotatably fitting the telescopic component of the telescopic module 2 onto the connecting shaft 5. Compared with existing telescopic modules with upper and lower covers, this telescopic module 2 eliminates at least the lower cover. That is, the lower cover of the original telescopic module can be combined with the first housing 1 or the second housing 6 of the electronic device accessory 100. By eliminating at least one component, at least one set of molds can be eliminated, and assembly steps can be reduced, which helps to reduce the production cost of the electronic device accessory 100. On the other hand, it also helps to effectively reduce the thickness of the telescopic module 2, thereby reducing the overall thickness of the electronic device accessory 100 and facilitating the thinner and lighter design of the electronic device accessory 100. On the other hand, while ensuring that the telescopic module 2 does not occupy too much space, the connecting cable 22 can be extended and retracted flexibly and smoothly, which greatly improves the utilization rate of the internal space of the electronic device accessory 100 to meet the operational needs in different scenarios, thereby improving the user experience; or, within the limited internal space of the electronic device accessory 100, more functional devices can be installed, which facilitates the multi-functional application of the electronic device accessory 100.

[0080] Overall, this electronic device accessory 100 allows for a more convenient design that is both lightweight and multifunctional. The extension and retraction of the connecting cable 22 are more flexible and smooth, and it offers a high cost-performance ratio, resulting in a better user experience and making it easier to promote and apply in the market.

[0081] Embodiment 1 of the electronic device accessory 100 of this utility model

[0082] To enable those skilled in the art to better understand the present invention, the following will be described in conjunction with the appendix. Figures 1 to 11 The technical solution in Embodiment 1 of this utility model will be clearly and completely described below. Unless otherwise specified, the following embodiments and features in Embodiment 1 can be combined with each other.

[0083] It should be noted that the height of most electronic device accessories 100 (such as power strips and power banks) is generally much greater than the height of the telescopic module 2. The telescopic module 2 is a separate component built into the electronic device accessory 100. To ensure the structural stability of the telescopic module 2 and to facilitate its installation and fixation, in some specific embodiments of Example 1, such as... Figures 1 to 3 As shown, the telescopic module 2 also includes a cover 21, which covers the first housing 1 in the mounting area 11 and together with the first housing 1 forms a mounting cavity 3. The telescopic module and the connecting shaft 5 are both installed within the mounting cavity 3. Specifically, the connecting shaft 5 is disposed between the cover 21 and the first housing 1, located on the cover 21 and abutting against the first housing 1, or the connecting shaft 5 is disposed on the first housing 1 and abuts against the cover 21.

[0084] Of course, in some other specific embodiments of Embodiment 1, when the height of the electronic device accessory 100 (such as a power strip or power bank) is the same as or similar to the height of the telescopic module 2, the telescopic module 2 can be directly set together with the outer shell, so that the cover 21 can be directly omitted. That is, in this case, compared with the existing telescopic module, the telescopic module of this embodiment can omit the upper cover (corresponding to the cover 21) and the lower cover, and directly use the corresponding part of the outer shell as the upper and lower covers of the telescopic module. For example, the first shell 1 is used as the lower cover of the telescopic module, and the second shell 7 is used as the upper cover of the telescopic module, which is conducive to further reducing the thickness of the telescopic module 2, and thus further reducing the overall thickness of the electronic device accessory 100.

[0085] In some specific embodiments of Example 1, such as Figures 1 to 3 As shown, to achieve the closing of the cover 21 and the first housing 1, the cover 21 includes a cover body 211, and the first housing 1 includes a housing body 12. When the cover 21 and the first housing 1 are closed, a frame 4 is formed between the cover body 211 and the housing body 12 to jointly enclose the mounting cavity 3. Furthermore, to allow the connecting wire 22 to extend outside the mounting cavity 3, a wire-passing hole 41 is provided on the frame 4. The wire-passing hole 41 communicates with the mounting cavity 3 and is configured to allow the connecting wire 22 to pass through. That is, the connecting wire 22 extends outside the mounting cavity 3 or extends into the mounting cavity 3 through the wire-passing hole 41.

[0086] Optionally, to achieve the formation of the frame 4 between the cover body 211 and the shell body 12, at least the following three specific embodiments are available:

[0087] In the first specific implementation, such as Figures 1 to 3 As shown, the frame 4 includes a first frame 42 and a second frame 43. The first frame 42 is disposed on the side of the cover body 211 facing the first housing 1, and correspondingly, the second frame 43 is disposed on the side of the housing body 12 facing the cover body 21. The first frame 42 and the second frame 43 are connected to each other so that the cover body 21 and the first housing 1 are covered, and the first frame 42, the second frame 43, the cover body 211 and the housing body 12 can together form the mounting cavity 3.

[0088] To simplify the overall structure, for example, such as Figure 2 and Figure 3 As shown, the first frame 42 can be integrally formed with the cover body 211 to form the cover 21, and the second frame 43 can be integrally formed with the shell body 12 to form the first shell 1. Also exemplarily, the first frame 42 has a first groove (not shown in the figure) communicating with the mounting cavity 3, and the second frame 43 has a second groove (not shown in the figure) communicating with the mounting cavity 3. When the cover 21 and the first shell 1 are closed, the first groove and the second groove can be joined together to form the aforementioned threading hole 41.

[0089] Alternatively, in a second specific embodiment (not shown in the figure), a frame is provided on the cover body 211. For example, when the cover body 21 and the first housing 1 are closed, in the mounting area 11, the frame on the cover body 211 can be fitted with the first housing 1 or bonded to the first housing 1, so as to cover the cover body 21 on the first housing 1.

[0090] Alternatively, in a third specific embodiment (not shown in the figure), the frame is provided on the shell body 12. For example, the frame is located at the position corresponding to the mounting area 11. When the cover 21 and the first shell 1 are closed, the cover 21 can be directly placed on the frame, and the cover 21 can be placed on the first shell 1 by means of fitting or bonding the frame to the cover body 211.

[0091] In some specific embodiments of Example 1, such as Figures 1 to 3 As shown, to ensure the stability of the coiled connecting wire 22, its cross-section is flat. Furthermore, when the lower cover of the telescopic module 2 is shared with the first housing 1 of the electronic device accessory 100, the width of the connecting wire 22 of the telescopic module 2 can range from 5mm to 8mm. Correspondingly, its maximum current carrying capacity can reach 5A to 6A. Clearly, compared to the telescopic module 2, which includes both an upper and lower cover, has a maximum width of only 6mm and a maximum current carrying capacity of only 5A, this significantly improves the utilization of the internal space of the telescopic module 2, facilitating effective compatibility with high current and high power requirements.

[0092] In some specific embodiments of Example 1, in the mounting area 11 of the first housing 1, the distance H between the side of the cover body 211 facing away from the first housing 1 (which may correspond to the top surface) and the side of the shell body 12 facing away from the cover body 21 (which may correspond to the bottom surface) (see [reference]). Figure 4 The thickness ranges from 10mm to 16mm. That is, the total thickness of the telescopic module 2 and the first housing 1 after assembly ranges from 10mm to 16mm. Clearly, compared to the case where the telescopic module 2 includes both the upper and lower covers, and the total thickness of the telescopic module 2 and the electronic device accessory 100 is 18mm, the overall thickness can be significantly reduced, facilitating a thinner and lighter design to meet ultra-thin requirements, thereby enhancing market competitiveness.

[0093] In some specific embodiments of Example 1, such as Figure 2 , Figure 3 and Figure 5 As shown, to improve the connection stability and reliability between the cover body 21 and the first housing 1, the connecting shaft 5 is integrally formed on the housing body 12. Furthermore, within the frame 4, a mounting post 13 protrudes between the cover body 211 and the housing body 12, and the mounting post 13 is configured to connect the cover body 211 and the housing body 12 together via a connector (not shown in the figure).

[0094] For example, the connecting shaft 5 is integrally formed on the housing body 12 in the mounting area 11. At least two mounting posts 13 are protruding on the housing body 12 around the connecting shaft 5 and inside the frame 4. After the cover 21 is closed on the first housing 1, it can be threaded to the mounting posts 13 by screws, bolts or other connectors to firmly connect the cover 211 to the housing body 12, so as to ensure the stability and durability of the telescopic module 2 during frequent use and help reduce the failure rate of electronic device accessories 100.

[0095] In some specific embodiments of Example 1, such as Figure 2 and Figure 3As shown, to enable the winding of the telescopic module 2 and ensure that the portion of the connecting wire 22 extending out of the mounting cavity 3 can be extended or shortened, the wire telescopic assembly also includes a winding reel 23, an electrical connection assembly 24, a retraction control assembly 25, and a locking element 26. The winding reel 23 is sleeved on the connecting shaft 5 and can rotate around it. The winding reel 23 has a wire groove 231. The electrical connection assembly 24 is located at the bottom of the winding reel 23 and sleeved on the connecting shaft 5. The connecting wire 22 has a connecting end 221 and an external end 222. The connecting end 221 of the connecting wire 22 is mounted on the winding reel 23 and electrically connected to the electrical connection assembly 24. The middle segment of the connecting wire 22 is wound around the connecting shaft 5 in the wire groove 231 of the winding reel 23. The external end 222 of the connecting wire 22 extends out of the mounting cavity 3. The retraction control assembly 25 is located on the winding reel 23 and is configured to control the extended connecting wire 22 to automatically retract into the wire groove 231. The locking element 26 is configured to prevent the winding reel 23 from rotating to limit the length of the connecting wire 22 extending out of the mounting cavity 3.

[0096] For example, the connecting wire 22 is wound around the wire groove 231 of the winding reel 23 and electrically connected to the electrical connection component 24. When the user manually pulls the outer end 222 of the connecting wire 22, the connecting wire 22 can gradually extend out of the mounting cavity 3, so that the extension length of the connecting wire 22 becomes longer and longer. At the same time, the connecting wire 22 can drive the winding reel 23 to rotate around the connecting shaft 5 to release the wire, and the electrical connection component 24 can at least partially rotate with the winding reel 23 around the connecting shaft 5. The retraction control component 25 continuously stores the rebound force during the rotation of the winding reel 23. When the connecting wire 22 extends to the preset length, the locking member 26 can prevent the winding reel 23 from rotating, thereby stopping the connecting wire 22 from extending outward. In addition, when it is necessary to retract the connecting wire 22, the retraction control component 25 can also release the rebound force, so that the extended connecting wire 22 automatically retracts into the mounting cavity 3 and is wound around the wire groove 231 of the winding reel 23 around the connecting shaft 5.

[0097] It should be noted that the specific structures of the winding disc 23, electrical connection assembly 24, retraction control assembly 25 and locking member 26 mentioned here can adopt existing structures or newly created structures, and there is no special limitation here, as long as they each perform their corresponding functions.

[0098] In some specific embodiments of Example 1, such as Figure 2 and Figure 3 As shown, the connecting shaft 5 is positioned between the cover 21 and the first housing 1, with one end of the connecting shaft 5 attached to the first housing 1 and the other end either a free end or attached to the cover 21. This allows the telescopic assembly fitted onto the connecting shaft 5 to rotatably mount on the first housing 1. Additionally, a locking member 26 is provided on the cover 21.

[0099] In some specific embodiments of Example 1, such as Figure 2 , Figure 3 , Figures 5 to 7 As shown, to improve the reliability and stability of the electrical connection of the connecting line 22, the electrical connection assembly 24 includes a main circuit board 241 and an adapter circuit board 242. The main circuit board 241 is mounted on the first housing 1 and sleeved on the connecting shaft 5. The adapter circuit board 242 is mounted on the winding reel 23, sleeved on the connecting shaft 5, and rotates relative to and electrically contacts the main circuit board 241. The connecting end 221 of the connecting line 22 is electrically connected to the adapter circuit board 242.

[0100] Understandably, during the rotation of the winding reel 23 around the connecting shaft 5, the main circuit board 241 remains fixed relative to the connecting shaft 5, while the adapter circuit board 242 and the connecting wire 22 rotate with the winding reel 23 relative to the main circuit board 241 and around the connecting shaft 5. In this way, during the rotation of the winding reel 23, the adapter circuit board 242 and the connecting wire 22 remain relatively stationary, which obviously helps to ensure that the connecting wire 22 is securely connected to the adapter circuit board 242, and prevents the connection from being pulled and twisted or even broken due to the relative rotation of the two.

[0101] In some specific embodiments of Example 1, such as Figures 5 to 7 As shown, to achieve electrical connection between the circuit main board 241 and the adapter circuit, and for both to be fitted onto the connecting shaft 5, the circuit main board 241 has a first connecting hole 2411 through which the connecting shaft 5 passes, and the circuit main board 241 has at least one annular groove 2412 recessed therein. The annular grooves 2412 are arranged radially around the first connecting hole 2411. In short, the annular grooves 2412 are concentric annular grooves 2412.

[0102] Correspondingly, the adapter circuit board 242 has a second connection hole 2421 for the connecting shaft 5 to pass through, and the adapter circuit board 242 has at least one electrical contact 2422. The electrical contacts 2422 are arranged circumferentially around the second connection hole 2421 and are electrically in contact with at least one annular groove 2412.

[0103] For example, the connecting shaft 5 is sequentially inserted into the first connecting hole 2411 and the second connecting hole 2421, so that the circuit board 241 and the adapter circuit board 242 are sequentially sleeved on the connecting shaft 5. The annular groove 2412 is located on the side of the circuit board 241 facing the cover 21, and the electrical contact 2422 is located on the side of the adapter circuit board 242 away from the cover 21. When both the circuit board 241 and the adapter circuit board 242 are sleeved on the connecting shaft 5, the electrical contact 2422 on the adapter circuit board 242 can engage with the corresponding annular groove 2412. During the rotation of the adapter circuit board 242 with the winding disc 23 relative to the connecting shaft 5, the electrical contact 2422 can slide around the connecting shaft 5 within the corresponding annular groove 2412.

[0104] It should be noted that all electrical contacts 2422 may be located on the same circumference or on different circumferences. No particular limitation is made here. It is only necessary to ensure that at least one electrical contact 2422 is electrically connected to the corresponding annular groove 2412 to ensure that the adapter circuit board 242 can transfer the electrical signals of the circuit board 241.

[0105] For example, such as Figure 8 and Figure 9 As shown, in order to ensure that the adapter circuit board 242 is securely mounted on the winding reel 23 and rotates with the winding reel 23, a positioning cylinder 236 and a limiting member 235 are provided on the side of the winding reel 23 facing the first housing 1. Correspondingly, a limiting hole 2423 is also provided on the adapter circuit board 242. When the adapter circuit board 242 is mounted on the winding reel 23, the positioning cylinder 236 is inserted into the second connecting hole 2421 of the adapter circuit board 242, and the connecting shaft 5 passes through the positioning cylinder 236 to fit the adapter circuit board 242 onto the connecting shaft 5. The limiting member 235 is inserted into the corresponding limiting hole 2423 so that the adapter circuit board 242 can be fixed relative to the winding reel 23 to rotate with the winding reel 23, but will not rotate around the connecting shaft 5.

[0106] In some specific embodiments of Example 1, such as Figure 6 and Figure 7 As shown, to improve the reliability and stability of the electrical connection of the electrical connection assembly 24, each electrical contact 2422 of the adapter circuit board 242 includes at least one electrical connection terminal 24221 (see Figure 24221). Figure 7 The number of electrical connection terminals 24221 of each electrical contact 2422 and the number of annular grooves 2412 (see...) Figure 6 The number of electrical contacts 24221 is the same, and each electrical connection terminal 24221 is electrically connected to each annular groove 2412 in a one-to-one correspondence. Understandably, in this case, all electrical contacts 2422 are located on the same circumference.

[0107] For example, if the number of electrical contacts 2422 is set to three and the number of annular grooves 2412 is set to five, then the three electrical contacts 2422 are arranged around the second connection hole 2421 in the same circumferential gap, and the number of electrical connection terminals 24221 of each electrical contact 2422 is also five, and the five electrical connection terminals 24221 of each electrical contact 2422 are electrically connected to the five annular grooves 2412 in a one-to-one correspondence.

[0108] In some specific embodiments of Example 1, such as Figure 3 and Figure 5As shown, to further reduce the space occupied by the telescopic module 2 and thus reduce the overall thickness of the device, the shell body 12 of the first housing 1 has a first clearance groove 121 recessed on the side facing the cover 21. The circuit board 241 is housed in the first clearance groove 121, and at least a portion of the circuit board 241 is adapted to the first clearance groove 121 to restrict its rotation relative to the connecting shaft 5. Understandably, one end of the circuit board 241 has a rectangular structure, and the first clearance groove 121 is adapted to the rectangular end of the circuit board 241. Thus, during the process of the winding disc 23 driving the adapter circuit board 242 to rotate around the connecting shaft 5, the circuit board 241 is restricted by the first clearance groove 121 and cannot rotate around the connecting shaft 5, thereby ensuring that the circuit board 241 can be relatively fixedly sleeved on the connecting shaft 5.

[0109] In some specific embodiments of Example 1, such as Figure 2 and Figure 8 As shown, similarly, to further reduce the space occupied by the telescopic module 2 and thus reduce the overall thickness, the winding reel 23 has a second clearance groove 232 recessed on the side facing the first housing 1, and the adapter circuit board 242 is accommodated in the second clearance groove 232 (see...). Figure 2 and Figure 9 ).

[0110] In some specific embodiments of Example 1, in order to fit the winding reel 23 onto the connecting shaft 5 and to retract the connecting wire 22, a mounting hole 233 is provided in the middle of the winding reel 23, through which the connecting shaft 5 passes. The retraction control assembly 25 includes an elastic element 251, which is accommodated in the mounting hole 233. One end of the elastic element 251 is connected to the connecting shaft 5, and the other end abuts against the wall of the mounting hole 233 or is connected to the winding reel 23, so as to store or release energy during the rotation of the winding reel 23.

[0111] Understandably, during the process of unwinding the wire by rotating the winding reel 23 around the connecting shaft 5, the other end of the elastic element 251 can rotate together with the winding reel 23, causing the elastic element 251 to undergo elastic deformation to store energy. When it is necessary to retract the connecting wire 22 that extends out of the mounting cavity 3, the elastic element 251 can release energy under the action of the rebound force, so that the other end of the elastic element 251 can drive the winding reel 23 to rotate in the opposite direction, thereby causing the connecting wire 22 to automatically wind back around the connecting shaft 5 into the wire groove 231 of the winding reel 23.

[0112] It should be noted that the elastic element 251 includes, but is not limited to, a clock spring or a torsion spring.

[0113] In some specific embodiments of Example 1, such as Figure 2 , Figure 3 and Figure 10As shown, to improve the reliability of the retraction control assembly 25 and simplify the overall structure, the retraction control assembly 25 also includes a pressure cap 252. The pressure cap 252 is sleeved on the connecting shaft 5 and covers the winding reel 23 to seal the mounting hole 233. Understandably, during the rotation of the winding reel 23, the pressure cap 252 can rotate with the winding reel 23, and the pressure cap 252 limits the elastic element 251 within the mounting hole 233 to ensure the reliability of the elastic element 251.

[0114] In addition, such as Figure 10 As shown, the locking member 26 engages with the pressure cap 252 to restrict the rotation of the pressure cap 252 when the connecting wire 22 extends to a predetermined length. Understandably, when the connecting wire 22 extends to the predetermined length, the locking member 26 can lock the pressure cap 252 to prevent the pressure cap 252 and the winding reel 23 connected to the pressure cap 252 from rotating relative to the connecting shaft 5, thereby stopping the winding reel 23 from unwinding wire.

[0115] In some specific embodiments of Example 1, such as Figure 2 and 3 As shown, to further reduce the space occupied by the telescopic module 2 and thus reduce the overall thickness, the winding reel 23 has a third clearance groove 234 recessed on the side opposite to the first housing 1, which communicates with the mounting hole 233. The pressure cap 252 is accommodated in the third clearance groove 234 (see figure). Figure 2 and Figure 10 ).

[0116] For example, the winding spool 23 has a third relief groove 234 recessed on the side opposite to the first housing 1, and a mounting hole 233 is formed at the bottom of the third relief groove 234 along the height direction of the winding spool 23. Understandably, the size of the groove of the third relief groove 234 may be larger than the size of the mounting hole 233.

[0117] In some specific embodiments of Example 1, in order to achieve the rotational locking of the winding reel 23 through the cooperation of the pressure cap 252 and the locking member 26, the pressure cap 252 is provided with a spiral track 2521 on the side facing the cover body 21. The track 2521 has a locking part 25211. The locking member 26 includes a connecting part 261 and a sliding part 262 connected together. The connecting part 261 of the locking member 26 is oscillatingly connected to the cover body 21. The sliding part 262 is in concave-convex cooperation with the track 2521 and can slide in the track as the pressure cap 252 rotates, and is locked in the locking part 25211.

[0118] Understandably, as the winding reel 23 rotates around the connecting shaft 5, the pressure cap 252 can rotate together with the winding reel 23. At the same time, the locking member 26 can swing relative to the cover body 21 and slide in the slide of the pressure cap 252. When the pressure cap 252 rotates to the point where the locking part 25211 engages with the locking member 26, the pressure cap 252 can no longer rotate, and then the winding reel 23 also stops rotating, thereby achieving the extension of the connecting wire 22 to the preset length.

[0119] For example, such as Figure 10 and Figure 11 As shown, the cover body 21 of the cover 21 has a recessed swing groove 2111, and a connecting post 2112 protrudes from the bottom of the swing groove 2111. Correspondingly, the connecting portion 261 of the locking member 26 has a third connecting hole 263, wherein the connecting post 2112 is inserted into the third connecting hole 263, so that the locking member 26 swings around the connecting post 2112 and is disposed in the swing groove 2111. In addition, the sliding portion 262 of the locking member 26 can protrude from the swing groove 2111 to engage with the slide rail of the pressure cover 252. Understandably, after the connecting line 22 extends to a preset length, the locking member 26 can swing to allow the sliding portion 262 to enter the locking portion 25211 of the pressure cover 252 to engage with the locking portion 25211. Similarly, in the initial state, the sliding part 262 of the locking member 26 engages with the locking part 25211. When the user manually stretches the connecting wire 22, the locking member 26 can also swing from the locking part 25211 of the pressure cover 252 into the slide, thereby releasing the lock on the winding reel 23 and allowing the winding reel 23 to rotate and release the wire.

[0120] In some specific embodiments of Example 1, such as Figure 4 As shown, to fully utilize the space of the electronic device accessory 100, a mounting groove 61 is recessed at the corresponding position in the mounting area 11 on the side opposite to the telescopic module 2. That is, the mounting groove 61 is recessed on the top surface of the top cover 6. The mounting groove 61 is configured for mounting another module. This facilitates the multi-functional application of the electronic device accessory 100.

[0121] For example, to fulfill other functions of the electronic device accessory 100 or to ensure the normal operation of the telescopic module 2, the depth of the cavity 7 of the electronic device accessory 100 is greater than the depth of the mounting cavity 3. This allows for the convenient installation of other functional components such as controllers in the spaces within the cavity 7 and outside the mounting cavity 3. Furthermore, at the corresponding position of the telescopic module 2, the top cover 6 has a recessed mounting groove 61 for installing another module, facilitating the integration of more functions while maintaining the same thickness of the electronic device accessory 100.

[0122] It should be noted that the other module mentioned includes, but is not limited to, a wireless charging module for watches.

[0123] Embodiment 2 of the electronic device accessory of this utility model (not shown in the figure)

[0124] The main technical features of Embodiment 2 are largely the same as those of Embodiment 1 above. The main differences between Embodiment 2 and Embodiment 1 are: the way the connecting shaft is set is different, and the positions of the circuit board and the locking component are different.

[0125] In some specific embodiments of Example 2 (not shown in the figure), the connecting shaft is disposed between the cover and the first housing, with one end of the connecting shaft disposed on the cover and the other end detachably connected to the first housing. In this way, the telescopic assembly sleeved on the connecting shaft can be rotatably disposed on the cover. Additionally, a locking element is disposed on the first housing.

[0126] In some specific embodiments of Example 2, to improve the reliability and stability of the electrical connection of the connecting wire, the electrical connection assembly includes a main circuit board and an adapter circuit board. The main circuit board is mounted on the cover and sleeved on the connecting shaft. The adapter circuit board is mounted on the winding reel, sleeved on the connecting shaft, and rotates relative to and electrically contacts the main circuit board. The connecting end of the connecting wire is electrically connected to the adapter circuit board.

[0127] Understandably, as the winding reel rotates around the connecting shaft, the main circuit board remains fixed relative to the connecting shaft, while the adapter circuit board and connecting wires rotate with the winding reel relative to the main circuit board and around the connecting shaft. In this way, the adapter circuit board and connecting wires remain relatively stationary during the rotation of the winding reel, which obviously helps to ensure a stable connection between the connecting wires and the adapter circuit board, preventing the connection from being pulled or twisted due to relative rotation, or even broken.

[0128] In some specific embodiments of Example 2, to further reduce the space occupied by the telescopic module and thus reduce the overall thickness of the device, a first clearance groove is recessed on the side of the cover body facing the first housing. The main circuit board is housed in the first clearance groove, and at least a portion of the main circuit board is adapted to the first clearance groove to restrict its rotation relative to the connecting shaft. Understandably, one end of the main circuit board has a rectangular structure, and the first clearance groove is adapted to the rectangular end of the main circuit board. Thus, during the rotation of the adapter circuit board around the connecting shaft by the winding disc, the main circuit board is restricted by the first clearance groove and cannot rotate around the connecting shaft, thereby ensuring that the main circuit board can be relatively fixedly fitted onto the connecting shaft.

[0129] In some specific embodiments of Example 2, similarly, in order to further reduce the space occupied by the telescopic module and reduce the thickness of the whole machine, a second clearance groove is provided on the side of the winding disc facing the cover, and the adapter circuit board is accommodated in the second clearance groove.

[0130] Embodiment 3 of the electronic device accessory of this utility model (not shown in the figure)

[0131] The main technical features of Embodiment 3 are largely the same as those of Embodiment 1 above. The main differences between Embodiment 3 and Embodiment 1 are: the way the connecting shaft is set is different, and the positions of the circuit board and the locking component are different.

[0132] In some specific embodiments of Example 3 (not shown in the figure), when the telescopic module does not have a cover, that is, compared with the existing telescopic membrane module, this telescopic module omits the upper and lower covers, one end of the connecting shaft is disposed on the first housing, and the other end of the connecting shaft abuts against or is disposed on the second housing.

[0133] In some specific embodiments of Example 3, to realize the winding of the telescopic module and ensure that the portion of the connecting wire extending out of the mounting cavity can be extended or shortened, the wire telescopic assembly further includes a winding reel, an electrical connection assembly, a retraction control assembly, and a locking member. The winding reel is sleeved on the connecting shaft and can rotate around it. The winding reel has a wire groove. The electrical connection assembly is located at the bottom of the winding reel and sleeved on the connecting shaft. The connecting wire has a connecting end and an external end. The connecting end of the connecting wire is mounted on the winding reel and electrically connected to the electrical connection assembly. The middle segment of the connecting wire is wound around the connecting shaft in the wire groove of the winding reel. The external end of the connecting wire extends out of the cavity. The retraction control assembly is located on the winding reel and configured to control the automatically retracted connecting wire into the wire groove. The locking member is located in the second housing and configured to prevent the winding reel from rotating, thereby limiting the length of the connecting wire extending out of the cavity.

[0134] For example, the connecting wire is wound around the groove of the winding reel and electrically connected to the electrical connection component. When the user manually pulls the outer end of the connecting wire, the connecting wire gradually extends out of the cavity, increasing its extension length. Simultaneously, the connecting wire drives the winding reel to rotate around the connecting shaft to release the wire. At least part of the electrical connection component can rotate with the winding reel around the connecting shaft. The retraction control component continuously stores rebound force during the rotation of the winding reel. Once the connecting wire reaches a preset length, the locking element prevents the winding reel from rotating, thus stopping the wire from extending further. Furthermore, when the connecting wire needs to be retracted, the retraction control component can release the rebound force, causing the extended connecting wire to automatically retract into the cavity and wind around the groove of the winding reel around the connecting shaft.

[0135] It should be noted that the specific structures of the winding reel, electrical connection assembly, retraction control assembly, and locking element described here can adopt existing structures or newly created structures, and there are no special limitations here, as long as they each perform their corresponding functions.

[0136] In some specific embodiments of Example 3, to improve the reliability and stability of the electrical connection of the connecting wire, the electrical connection assembly includes a main circuit board and an adapter circuit board. The main circuit board is mounted on the first housing and sleeved on the connecting shaft. The adapter circuit board is mounted on the winding reel, sleeved on the connecting shaft, and rotates relative to and electrically contacts the main circuit board. The connecting end of the connecting wire is electrically connected to the adapter circuit board.

[0137] Understandably, as the winding reel rotates around the connecting shaft, the main circuit board remains fixed relative to the connecting shaft, while the adapter circuit board and connecting wires rotate with the winding reel relative to the main circuit board and around the connecting shaft. In this way, the adapter circuit board and connecting wires remain relatively stationary during the rotation of the winding reel, which obviously helps to ensure a stable connection between the connecting wires and the adapter circuit board, preventing the connection from being pulled or twisted due to relative rotation, or even broken.

[0138] In some specific embodiments of Example 3, to further reduce the space occupied by the telescopic module and thus reduce the overall thickness of the device, a first clearance groove is recessed on the side of the first housing facing the second housing. The main circuit board is housed in the first clearance groove, and at least a portion of the main circuit board is adapted to the first clearance groove to restrict its rotation relative to the connecting shaft. Understandably, one end of the main circuit board has a rectangular structure, and the first clearance groove is adapted to the rectangular end of the main circuit board. Thus, during the rotation of the adapter circuit board around the connecting shaft by the winding disc, the main circuit board is restricted by the first clearance groove and cannot rotate around the connecting shaft, thereby ensuring that the main circuit board can be relatively fixedly fitted onto the connecting shaft.

[0139] In some specific embodiments of Example 3, similarly, in order to further reduce the space occupied by the telescopic module and reduce the thickness of the whole machine, a second clearance groove is recessed on the side of the winding reel facing the first housing, and the adapter circuit board is accommodated in the second clearance groove.

[0140] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of the claims of the present invention.
