[0055] 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.

[0056] This utility model embodiment provides a multifunctional electronic device accessory 100, which includes, but is not limited to, a power strip, a power bank, a data cable, and a charger, and can be used with 3C products that require power supply or data transmission. For ease of description, the following description mainly uses a power strip 100 as an example of the electronic device accessory 100.

[0057] like Figures 1 to 3 As shown, the multifunctional electronic device accessory 100 includes a first housing 1, a telescopic module 2, and a wireless charging module 3. The first housing 1 includes a first surface 111 (specifically, the top surface), and a mounting cavity 13 is formed within the first housing 1 (see figure). Figure 5 It should be noted that, taking electronic device accessory 100 as an example, such as power strip 100... Figure 1 and Figure 2 As shown, the first housing 1 of the electronic device accessory 100 adopts a rectangular structure design, and to ensure safety during use, the first housing 1 is made of a high-strength, high-temperature resistant insulating material. Of course, in other embodiments, the first housing 1 may also have a circular or other shapes, which are not particularly limited here.

[0058] In this embodiment, the telescopic module 2 includes a connecting cable 21. The telescopic module 2 is built into the mounting cavity 13 and is configured to extend or shorten the portion of the connecting cable 21 extending out of the mounting cavity 13. It should be noted that the connecting cable 21 can be a data transmission cable or a power connection cable 21. Users can adapt and pull out connecting cables 21 of different lengths from the telescopic module 2 according to different application scenarios, making it widely applicable and flexible.

[0059] In this embodiment, in order to integrate the wireless charging module 3 into the electronic device accessory 100, so that the electronic device accessory 100 can have wireless charging function in addition to having the function of retractable connecting cable 21, so as to realize the multi-functionality of the electronic device accessory 100, the wireless charging module 3 is rotatably connected to the first surface 111 of the first shell 1.

[0060] The position of the wireless charging module 3 in its initial state is defined as the first position (see [reference]). Figure 1 The maximum extreme position of the wireless charging module 3 when it is in use is set as the second position (see [link]). Figure 2 The wireless charging module 3 rotates at a fixed point relative to the first outer shell 1 between a first position and a second position. The wireless charging module 3 includes a charging surface 3111, which is parallel to the first surface 111 in the first position (see...). Figure 1 The charging surface 3111 forms a preset angle α with the first surface 111 at the second position (see [reference]). Figure 2 Understandably, the wireless charging module 3 can remain stationary at any angle between 0° and α, allowing users to wirelessly charge the device. This allows users to flexibly adjust the charging angle according to their actual usage scenarios and needs, ensuring accurate placement within the wireless charging area and improving charging efficiency. Furthermore, it increases the fun and flexibility of use, enhancing the user experience.

[0061] For example, when wireless charging is not required or when wireless charging is needed in the first position, the wireless charging module can be rotated and folded to fit against the first housing 1, thereby reducing the space occupied by the electronic device accessory 100. This is especially suitable for use in environments with limited space, such as desks and bedside tables, and also makes it convenient for users to carry and use when out and about, as well as for easy storage. When wireless charging is required at a suitable angle, the wireless charging module can be rotated from the first position or other positions to a suitable position and kept stationary, so that electronic devices such as watches can be placed against the charging surface 3111 for wireless charging.

[0062] It should be noted that the term "fixed-point rotation" as used here refers to the ability to remain stationary at each point during rotation, thereby ensuring the stability and reliability of the rotation. Specifically, fixed-point rotation can be achieved through damped rotation, or by other suitable methods to maintain a stationary position at a certain rotational location. The specific structure used can be an existing structure or a newly created structure, and no particular limitation is made here.

[0063] It should also be noted that, to ensure the safety and reliability of wireless charging, the wireless charging module has multiple protection functions to reduce the risk of equipment damage or safety accidents caused by overvoltage, overcurrent, or short circuits during the charging process. The specific protection structures used can be existing or innovative, and no particular limitation is made here.

[0064] In summary, compared with existing technologies, the multifunctional electronic device accessory 100 has at least the following beneficial effects: Based on a telescopic module 2 with a telescopic connecting cable 21 to adapt to different distances requiring varying cable lengths, the multifunctional electronic device accessory 100 also has a wireless charging module 3 fixedly rotatably connected to the first outer shell 1. This allows the wireless charging module 3 to rotate relative to the first outer shell 1 between a first position and a second position. This organically combines the telescopic module 2 and the wireless charging module 3, eliminating the need for a separate wireless charger. Users can perform both wired and wireless charging simultaneously, and multiple electronic devices can be charged both wired and wirelessly at the same time, improving functional integration and ease of use. It offers diverse functions and is suitable for various usage scenarios. Furthermore, the wireless charging module's rotation angle can be adjusted to adjust the charging angle according to the available space, ensuring convenient and accurate wireless charging alignment for the user. This not only improves wireless charging efficiency but also enhances charging convenience and space utilization.

[0065] 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 10 The technical solutions in the embodiments of this utility model are clearly and completely described below. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0066] In some embodiments, the wireless charging module 3 is configured to wirelessly charge at least a watch. Exemplarily, the wireless charging module 3 is a watch wireless charging module 3 used to wirelessly charge a watch. Of course, in other examples, the wireless charging module 3 can not only wirelessly charge a watch, but also wirelessly charge other electronic products.

[0067] Understandably, the electronic device accessory 100, such as the power strip 100, through the organic combination of the telescopic module 2 and the watch wireless charging module, allows users to wirelessly charge their watches while charging other electronic devices without the need for a separate watch charger, thus improving charging convenience and space utilization.

[0068] In some embodiments, the preset included angle is 90°. For example, when the wireless charging module is in the first position, the rotation angle of the wireless charging module can be 0°. When the wireless charging module is in the second position, the rotation angle of the wireless charging module can be 90°.

[0069] Understandably, the wireless charging module can rotate freely between 0° and 90° and stop at any angle between 0° and 90° to meet the user's different viewing experience.

[0070] In some embodiments, to enable the electronic device accessory 100 to have more functions, at least one of a USB interface and a power jack 15 is provided on the first housing 1. It should be noted that in order to accommodate multiple connectors, there may be multiple USB interfaces, and similarly, there may be multiple power jacks 15.

[0071] For example, such as Figure 1 and Figure 2 As shown, the power strip 100 has two USB ports on one side of its first outer casing 1, and a retractable module 2 with its own connecting cable 21 extending outwards to support all 3C products powered by USB A and C ports, and to charge common electronic devices such as mobile phones, computers, and power banks. Furthermore, the first surface 111 of the first outer casing 1 has two five-hole AC power sockets 15 to meet the charging needs of appliances with higher power requirements. In addition, the overall layout of the USB ports and power sockets 15 is reasonable, with high compatibility, which helps to further improve the functionality, ease of use, and space utilization of this electronic device accessory 100.

[0072] In some embodiments, such as Figure 3 and Figure 4 As shown, the multifunctional electronic device accessory 100 also includes a main circuit board 5, an AC module 6, and a USB terminal block 7, all built into the mounting cavity 13. The retractable module 2, wireless charging module 3, AC module 6, and USB terminal block 7 are all electrically connected to the main circuit board 5. The AC module 6 corresponds to the power jack 15, and the USB terminal block 7 corresponds to the USB interface. That is, each functional module is electrically connected to the main circuit board 5, which simplifies the overall structure and makes it more compact.

[0073] For example, the telescopic module 2 can be connected to the main circuit board 5 via a first adapter plate (not shown in the figure), the wireless charging module 3 can be connected to the main circuit board 5 via a wire 36, the AC module 6 can be connected to the plug 8 for use with AC power via an AC cable (not shown in the figure), and can also be electrically connected to the main circuit board 5 via an intermediate connecting wire (not shown in the figure). The USB terminal 7 can be connected to the main circuit board 5 via a second adapter plate (not shown in the figure).

[0074] In some embodiments, to make the structure of the electronic device accessory 100 more compact and facilitate miniaturization and ultra-thin design, the projections of the wireless charging module 3 and the retractable module 2 on the first housing 1 at least partially overlap in the thickness direction. Optionally, the projection of the wireless charging module 3 on the first housing 1 completely overlaps with the projection of the retractable module 2 on the first housing 1, or is located within the projection of the retractable module 2 on the first housing 1. In this way, the addition of the wireless charging module 3 does not require the space of the first housing 1 in the length and width directions, which is beneficial to the miniaturization design of the electronic device accessory 100 and also to the folding design of the electronic device accessory 100 in the length direction, thereby further improving portability.

[0075] It should be noted that, as Figure 3 and Figure 10 As shown, the electronic device accessory 100 also includes an anti-slip structure 35. The first housing 1 includes a second surface 121, wherein the second surface 121 and the first surface 111 are arranged opposite to each other. The anti-slip structure 35 is disposed on the second surface 121 of the first housing 1, so that the electronic device accessory 100 can be placed more stably on a work surface such as a desktop.

[0076] For example, the anti-slip structure 35 can be an anti-slip pad or a textured structure, etc. The anti-slip structure 35 can be an existing structure or a newly created structure, and no particular limitation is made here.

[0077] In some embodiments, such as Figure 1 , Figure 2 and Figure 5 As shown, the first outer casing 1 includes a first front cover 11 and a first bottom cover 12, which fit together to form a mounting cavity 13 (see figure). Figure 5 The top surface of the first cover 11 is the first surface 111, and the bottom surface of the first bottom cover 12 is the second surface 121. The first bottom cover 12 has a connecting shaft 122 protruding from the mounting cavity 13 and facing the first cover 11.

[0078] like Figure 5 As shown, the telescopic module 2 also includes a wire telescopic component 22 and a cover 23. The wire telescopic component 22 is sleeved on the connecting shaft 122 and configured to extend or shorten the portion of the connecting wire 21 extending out of the mounting cavity 13. The cover 23 is fitted onto the first bottom cover 12 so that the wire telescopic component 22 is housed between the cover 23 and the first bottom cover 12. Understandably, compared to the prior art, this telescopic module 2 shares the first bottom cover 12 with the electronic device accessory 100. This eliminates the need for a separate bottom cover for the telescopic module 2, simplifying the overall structure and allowing for a reduction in the thickness of the electronic device accessory 100, thus facilitating ultra-thin design.

[0079] Furthermore, to further reduce the thickness of the electronic device accessory 100, the first surface 111 has a recessed mounting groove 1111 at the position corresponding to the telescopic module 2 (see...). Figure 2 and Figure 9 When the wireless charging module 3 is in the first position, it is housed in the mounting slot 1111.

[0080] For example, a mounting groove 1111 is recessed on the first surface 111 of the first housing 1 directly above the telescopic module 2. When the wireless charging module is housed in the mounting groove 1111, the top surface of the wireless charging module is flush with the top surface of the first housing 1. In this way, adding a wireless charging module will not increase the overall thickness of the electronic device accessory 100, and it is also suitable for the ultra-thin design of the electronic device accessory 100.

[0081] In some embodiments, such as Figures 5 to 7 As shown, the wireless charging module 3 includes a second housing 31, a wireless charging plate 32, and a coil 33. To realize the wireless charging function of the wireless charging module 3, a cavity 313 is formed inside the second housing 31. The wireless charging plate 32 and the coil 33 are both built into the cavity 313, and the coil 33 is electrically connected to the wireless charging plate 32. For example, the wireless charging plate 32 is electrically connected to the main circuit board 5 through a wire 36. When the watch is placed on the charging surface 3111 of the second housing 31, the watch can be wirelessly inductively charged by the energized coil 33.

[0082] To enable the wireless charging module 3 to rotate at a fixed point relative to the first outer shell 1, the second outer shell 31 is rotatably connected to the first outer shell 1 via a damping rotation mechanism 4. Of course, in other embodiments, the second outer shell 31 may also be rotatably connected to the first outer shell 1 via other suitable structures, which are not particularly limited here.

[0083] In some embodiments, to achieve a fixed-point rotatable connection between the second outer shell 31 and the first outer shell 1 via a damping rotation mechanism 4, such as... Figures 5 to 7 , Figure 9 and Figure 10 As shown, the damping rotation mechanism 4 includes a damping shaft 41, a first connecting frame 42, and a second connecting frame 43. One end of the first connecting frame 42 is damped and rotatably connected to one end of the second connecting frame 43 via the damping shaft 41, and the other end of the first connecting frame 42 is connected to the second outer shell 31. The other end of the second connecting frame 43 is connected to the first outer shell 1. It should be noted that both the first connecting frame 42 and the second connecting frame 43 can be precision machined from stainless steel to ensure the smoothness and stability of the rotation of the wireless charging module 3.

[0084] In some embodiments, such as Figures 5 to 7As shown, the second outer casing 31 includes a second front cover 311 and a second bottom cover 312, which overlap each other and together form a cavity 313. One outer wall surface (specifically, the top surface) of the second front cover 311 is the charging surface 3111. The other end of the first connecting bracket 42 is connected to the middle portion of one end of the second bottom cover 312 (see...). Figure 7 The other end of the second connecting bracket 43 is connected to the first cover 11 of the first housing 1 (see...). Figure 8 In this way, the damping rotation mechanism 4 can be connected between the wireless charging module 3 and the first outer shell 1, so that the wireless charging module 3 can rotate at a fixed point relative to the first outer shell 1 through the damping rotation of the first connecting frame 42 and the second connecting frame 43 relative to the damping rotating shaft 41.

[0085] In some embodiments, such as Figures 6 to 10 As shown, to ensure the smooth rotation of the wireless charging module 3, the second bottom cover 312 is provided with positioning shafts 3121 on both opposite ends of the damping shaft 41 along the axial direction of the damping shaft 41. These positioning shafts 3121 are configured to keep the rotating wireless charging module 3 balanced relative to the damping rotation mechanism 4. Understandably, since the damping shaft 41 is located in the middle of the second bottom cover 312, meaning the connection between the wireless charging module 3 and the first outer shell 1 is mainly rotatably connected in the middle of the first outer shell 1, and the rotation between the wireless charging module 3 and the first outer shell 1 is damped, the damping during rotation is relatively large. Therefore, by providing positioning shafts 3121 on both opposite ends of the damping shaft 41 to position the wireless charging module 3 during rotation, the second bottom cover 312 can effectively solve the problem of the wireless charging module 3 not wobbling relative to the damping rotation mechanism 4, thus preventing asynchronous left and right tilting.

[0086] In some embodiments, to further ensure the smoothness and stability of the rotation of the wireless charging module 3, each positioning shaft 3121 is coaxially arranged with the damping shaft 41. It should be noted that, in order to reduce production costs, the positioning shaft 3121 can be made of plastic material, and of course, other suitable materials can also be used, without any particular limitation.

[0087] In some embodiments, such as Figure 6 As shown, the positioning shaft 3121 has a wire-passing hole 31211 in the axial direction. For example, the wire 36 of the main circuit board 5 connected to the wireless charging board 32 can pass through the wire-passing hole 31211 for wire-passing. In this way, the wire 36 can pass through the damping shaft 41 in the axial direction, so as to ensure that the wire 36 is not easily tangled or pulled during the rotation of the wireless charging module 3, which helps to improve the service life of the wireless charging module 3.

[0088] In some embodiments, such as Figure 3As shown, in order to achieve the positioning function of the wireless charging module 3 by means of the positioning shaft 3121, the first cover 11 of the first outer shell 1 is provided with a first positioning groove 1112 on the side facing the first bottom cover 12, and the first positioning groove 1112 is adapted to the positioning shaft 3121.

[0089] In some embodiments, such as Figure 3 , Figure 4 and Figure 8 As shown, in order to improve the stability and reliability of the wireless charging module 3 during rotation and to prevent shaking and other problems, a pressure cover 1113 is provided on the first cover 11 of the first outer shell 1. The pressure cover 1113 is configured to press down all the positioning shafts 3121, and a second positioning groove is provided on the pressure cover 1113. The second positioning groove is adapted to the positioning shafts 3121.

[0090] For example, during assembly, the first connecting bracket 42, the damping shaft 41, and the second connecting bracket 43 can be rotatably connected together first, and then the other end of the first connecting bracket 42 can be connected to the second bottom cover 312 using multiple threaded fasteners (such as screws, bolts, etc.) (see...). Figure 7 After assembling the wireless charging module 3, the other end of the second connecting bracket 43 is then connected to the first cover 11 using multiple threaded connectors (such as screws, bolts, etc.) (see...). Figure 8 Finally, on the side of the first cover 11 facing the first bottom cover 12 and corresponding to the position of the positioning shaft 3121, the pressure cover 1113 is fastened onto the first cover 11 so as to press the two positioning shafts 3121 by the pressure cover 1113, and the pressure cover 1113 is fixed to the first cover 11 by multiple threaded connectors (such as screws, bolts, etc.) so as to realize the fixed-point rotational connection between the wireless charging module 3 and the first outer shell 1.

[0091] In some embodiments, such as Figures 5 to 7 As shown, a first magnetic body 131 is provided in the mounting cavity 13 of the first outer shell 1, and a second magnetic body 34 is provided in the cavity 313 of the second outer shell 31. The second magnetic body 34 is located in the hollow position of the coil 33, and is aligned with the first magnetic body 131. When the wireless charging module 3 is in the first position, the first magnetic body 131 and the second magnetic body 34 are magnetically attracted to each other. Understandably, when the wireless charging module 3 rotates to the first position, the second magnetic body 34 inside the wireless charging module 3 can be magnetically attracted to the first magnetic body 131, so that the wireless charging module 3 is fixedly installed on the first outer shell 1, and a zero-degree self-locking experience can be achieved for the wireless charging module 3.

[0092] In addition, by setting a second magnetic body 34 inside the second housing 31 and positioning the second magnetic body 34 in the hollow position of the coil 33, that is, by fitting the coil 33 onto the second magnetic body 34, it is ensured that the second magnetic body 34 corresponds exactly to the middle position of the charging surface 3111. In this way, for example, when the watch is placed on the charging surface 3111 for charging, because the watch is small, the second magnetic body 34 can be used to position the watch, ensuring that the watch is accurately placed in the middle position of the charging surface 3111 for wireless charging.

[0093] It should be noted that there may be one or at least two first magnetic bodies 131; similarly, there may be one or at least two second magnetic bodies 34, wherein each first magnetic body 131 may be magnetically attracted to at least one second magnetic body 34. The number and arrangement of the first magnetic bodies 131 and the second magnetic bodies 34 can be determined according to actual needs.

[0094] For example, a first magnetic body 131 is provided and is located on top of the telescopic module 2. A second magnetic body 34 is provided and is fitted with a coil 33. That is, the second magnetic body 34 can be located at the center of the wireless charging module to achieve a balance in the magnetic attraction of the wireless charging module 3, which helps to ensure the reliability and stability of the self-locking mechanism.
