Description

Technical Field

[0001] This utility model relates to the field of electronic device accessories technology, and in particular to a charging device. Background Technology

[0002] With the development of electronic devices (such as mobile phones), these devices have become essential for people's daily lives and travel, basically covering all kinds of daily application scenarios. Charging devices can conveniently charge electronic devices to improve their battery life.

[0003] Retractable charging devices consist of a retractable cable module within the charging equipment. When the user needs to charge the device, the retractable cable can be pulled out through the module to charge the electronic device. When the user does not need to charge the device, the retractable cable can be wound back around the module. This design allows for a longer retractable cable and a smaller charging device size, and is currently favored by many users.

[0004] However, existing retractable charging devices are often limited by size and internal retractable cable modules, preventing the retractable cable from exceeding one meter in length. This fails to meet users' needs for charging over long distances. Directly lengthening the retractable cable, on the other hand, would increase the diameter of the retractable cable module, taking up too much internal space and requiring a larger charging device. In short, it's currently impossible to perfectly balance the needs of users with longer retractable cables and smaller charging devices. Utility Model Content

[0005] In view of at least some of the problems and defects in the prior art, this utility model discloses a charging device to solve the problem that the prior art cannot simultaneously meet the user's needs for a long telescopic cable length and a small charging device size.

[0006] Specifically, this utility model provides a charging device comprising: a charging body having a charging module disposed inside; a retractable cable module disposed within the charging body, the retractable cable module including a retractable cable with an extension section, one end of the retractable cable away from the extension section being electrically connected to the charging module, the extension section extending beyond the exterior of the charging body, a retractable cable connector disposed on the retractable cable, the retractable cable connector being located on the end of the extension section away from the charging module; and a storage device connected to the extension section for storing the retractable cable connector.

[0007] The charging device provided in this embodiment extends the length of the telescopic cable without increasing the size of the charging device by setting an extension section on the telescopic cable. In addition, the solution also includes a storage device to store the telescopic cable connector, thereby avoiding an excessively large charging body and improving portability.

[0008] In one embodiment of this utility model, the telescopic cable includes a lifting means connected between the outer extension and the telescopic cable connector. The outer extension and the lifting means are electrically connected inside the storage device. When the telescopic cable connector is stored in the storage device, the lifting means can be bent to form the handle space.

[0009] In one embodiment of this utility model, the length of the lifting means is greater than the length of the extension segment.

[0010] In one embodiment of this utility model, the telescopic cable module includes a module body, and the telescopic cable includes a winding section, an extension section, and a lifting means connected in sequence, wherein the winding section is wound around the module body; wherein the length of the winding section is greater than the length of the lifting means, and the length of the lifting means is greater than the length of the extension section.

[0011] In one embodiment of this utility model, the storage device is provided with a receiving groove on the outside, and the telescopic cable connector can be stored in the receiving groove. When the telescopic cable connector is stored in the receiving groove, the lifting handle bends to form the lifting handle space.

[0012] In one embodiment of this utility model, a groove is provided at one end of the telescopic connector near the lifting means, and a protrusion is provided in the receiving groove and corresponds to the groove. The extending direction of the groove and the protrusion is the same as the sliding direction of the telescopic connector in the receiving groove.

[0014] In one embodiment of this utility model, a locking structure is provided at one end of the charging body near the storage device. The locking structure is used to lock the extension segment to prevent the extension segment from sliding.

[0015] In one embodiment of the present invention, the locking structure includes a locking member and a locking groove. The sliding groove is located on one end of the charging body near the storage device, and the locking member is located in the sliding groove. The locking structure includes a locked state. When the locking structure is in the locked state, the end of the locking member near the outer extension abuts against the outer extension.

[0016] In one embodiment of the present invention, the charging module includes a battery, the telescopic cable module is located inside the charging body at one end near the storage device, and the charging module is located at the other end inside the charging body; and / or, the charging body is further provided with a mounting cover plate, the mounting cover plate being used to fix the telescopic cable module.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them.

[0028] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0029] like Figure 1 As shown, this embodiment of the present invention provides a charging device 10. The charging device 10 provided in this embodiment of the present invention is used, for example, to charge electronic devices. Specifically, see... Figure 1The charging device 10 includes, for example, a charging body 100, a retractable cable module, and a storage device 300. The charging body 100 internally houses, for example, the basic structure of a power bank, including a charging module 110 and a circuit board. The retractable cable module 200 is disposed within the charging body 100. The retractable cable module 200 includes a retractable cable 210, which includes an extension segment 212. One end of the retractable cable 210, away from the extension segment 212, is electrically connected to the charging module 110. The extension segment 212 extends beyond the charging body 100. A retractable cable connector 214 is disposed on the retractable cable 210, located at the end of the extension segment 212 away from the charging module 110. The storage device 300 is connected to, for example, the extension segment 212. The storage device 300 is used to store the retractable cable connector 214, creating a handle space between the retractable cable connector 214 and the extension segment 212. For example, the retractable cable mentioned above is a data cable, which is used to power an external device through a retractable connector. The external device is an electronic device that can be charged through the data cable.

[0030] The charging device provided in this embodiment extends the length of the telescopic cable without increasing the size of the charging device by setting an extension section on the telescopic cable. Furthermore, the solution also includes a storage device to store the telescopic cable connector, thereby avoiding an excessively large charging body and improving portability.

[0031] Further, see Figure 1 The telescopic cable 210 includes a lifting handle 213 connecting the outer extension 212 and the telescopic cable connector 214. The outer extension 212 and the lifting handle 213 are electrically connected inside the storage device 300. When the telescopic cable connector 214 is stored in the storage device 300, the lifting handle 213 can be bent to form the handle space. By providing the lifting handle 213 located between the outer extension 212 and the telescopic cable connector 214, the length of the telescopic cable can be extended, and a handle space is formed so that the user can put their hand into the handle space to lift the charging device 10, thus making it convenient for the user to carry it daily.

[0032] As described above, the length of the lifting means 213 is greater than the length of the extension segment 212, thereby increasing the length of the retractable cable. Furthermore, the length of the extension segment 212 is greater than 5 cm, and / or the length of the lifting means 213 is, for example, greater than 10 cm. This allows for a significantly increased length of the retractable cable, providing users with a more flexible charging range, and also provides sufficient length to form a handle.

[0033] In one specific implementation, see Figure 1 The telescopic cable module 200 includes a module body 220, and the telescopic cable 210 includes a winding section 211, an extension section 212, and a lifting handle 213 connected in sequence. The winding section 211 is wound around the module body 220. The length of the winding section is greater than the length of the lifting handle 213, and the length of the lifting handle 213 is greater than the length of the extension section 212. This increases the length of the telescopic cable. Preferably, the length of the winding section 211 is 70 cm, the length of the extension section 212 is 10 cm, and the length of the lifting handle 213 is 20 cm. In this way, the maximum extension length of the retractable cable can reach 1 meter, thereby maximizing the length of the retractable cable to provide users with a flexible charging range. The main part of the retractable cable (70 cm) is wound around the module body 220 for convenient storage. Setting the length of the handle 213 to 20 cm allows the diameter of the handle space to be greater than 6 cm, providing sufficient space for the user's hand to pass through for carrying. Setting the length of the extension 212 to 10 cm increases the overall length of the retractable cable, but avoids it being too long and affecting the user's carrying experience.

[0034] In one specific implementation, see Figure 2 The storage device 300 has an external receiving groove 310, in which the telescopic connector 214 can be stored. When the telescopic connector 214 is stored in the receiving groove 310, the lifting handle 213 bends to form the carrying handle space. By providing the receiving groove 310 to store the telescopic connector 214, the situation where the telescopic connector 214 is exposed to the outside and is easily damaged, and is not conducive to carrying, is avoided.

[0035] As stated above, see also Figure 2 The telescopic connector 214 has a groove 2141 near the lifting means 213. A protrusion 311 is provided in the receiving groove 310, corresponding to the groove 2141. When the telescopic connector 214 is housed in the receiving groove 310, the protrusion 311 is nested within the groove 2141. The extending directions of the groove 2141 and the protrusion 311 are the same as the sliding direction of the telescopic connector 214 in the receiving groove 310. For example, the sliding direction of the aforementioned telescopic connector 214 in the receiving groove 310 is, for example,... Figure 2The x-direction is defined in the groove. By providing mutually cooperating grooves and protrusions, the fixing strength of the telescopic cable connector 214 in the receiving groove 310 can be improved, thereby improving the lifting stability and reducing the possibility that the telescopic cable connector 214 may fall out of the receiving groove 310 due to the user pulling the handle. For example, it can prevent the telescopic cable connector 214 from falling out of the receiving groove 310 along a direction perpendicular to the sliding direction. Preferably, the number of protrusions 311 is, for example, two, and the two protrusions 311 are correspondingly provided at the upper and lower ends of the telescopic cable connector 214. Correspondingly, the number of grooves 2141 is also, for example, two, and the two grooves 2141 are correspondingly provided at the upper and lower ends of the receiving groove 310.

[0036] In another specific implementation, see Figure 3 The number of lifting means 213 is two, and each of the two lifting means 213 is electrically connected to the extension segment 212. Correspondingly, the number of telescopic cable connectors 214 is two. The number of receiving slots 310 is also two, and the two receiving slots 310 are arranged opposite each other on both sides of the storage device 300 along the width direction of the storage device 300. The two telescopic cable connectors 214 are respectively housed in the two receiving slots 310. For example, the width direction of the storage device 300 mentioned here is, for example,... Figure 3 In the y-direction. By setting two retractable cable connectors, both connectors can supply power to external devices simultaneously, thus meeting the user's need to charge multiple devices.

[0037] In addition, see Figure 1 and Figure 3 A locking structure 120 is provided at one end of the charging body 100 near the storage device 300. The locking structure 120 is used to lock the outer extension 212 to prevent it from sliding. The locking structure 120 is, for example, a sliding locking structure. When the locking structure 120 is in the locked state, the outer extension 212 cannot slide or extend, thus preventing the user from pulling the handle and causing the telescopic cable 210 to extend or retract. Specifically, the locking structure 120 includes a locking member 122 and a locking groove 121. The sliding groove 121 is located on the end of the charging body 100 near the storage device 300, and the locking member 122 is located within the sliding groove 121. The locking structure 120 has a locked state. When the locking structure 120 is in the locked state, the end of the locking member 122 near the outer extension 212 abuts against the outer extension 212, preventing the outer extension 212 from extending, retracting, or sliding. Of course, the locking structure 120 can also be other structures that can lock the extension segment 212, and this application does not specifically limit it.

[0038] In addition, the charging module may also include, for example, a battery, see [link to documentation]. Figure 1 and Figure 3 The retractable cable module 200 is located inside the charging body 100 near one end of the storage device 300, and the charging module 110 is located inside the charging body 100 at the other end. And / or, the charging body 100 is further provided with a mounting cover 130, which is used to fix the retractable cable module 200. For example, the mounting cover 130 is fixedly connected to the module body 220. By providing the mounting cover 130 to fix the retractable cable module 200, displacement of the module body 220 due to the stretching of the retractable cable 210 is prevented. Specifically, the module body 220 includes a cable outlet 221, and the charging body 100 includes a cable passage 101. The extension segment 212 extends out of the charging body 100, for example, through the cable outlet 221 and through the cable passage 101. By placing the telescopic cable module 200 close to one end of the storage device 300, the distance between the cable outlet 221 and the cable passage 101 can be reduced, thereby making full use of the stretchable length of the telescopic cable 210 to provide users with a flexible charging range.

[0039] In summary, the charging device provided in this embodiment extends the length of the telescopic cable without increasing the size of the charging device by setting an extension section on the telescopic cable. Furthermore, this solution also includes a storage device to store the telescopic cable connector, thereby avoiding an excessively large charging body and improving portability.

Provided that the technical features do not conflict, the structure is not contradictory, and the purpose of this utility model is not violated, the technical solutions of the various embodiments can be arbitrarily combined and used.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
