[0002] Currently, mobile phone data cables, as accessories for mobile phones, can fully develop the potential functions of mobile phones and are gradually attracting people's attention. The supply and demand in the accessory market are also growing. Data cables, one of the main accessories for mobile phones, were originally just ordinary mobile phone accessories, mainly used for repairing and testing mobile phones and for business people to manage telephones through computers. Today, the application of data cables is quite widespread.

[0003] Existing data cables require varying lengths due to different usage methods and environments. Since a single data cable cannot be lengthened, it is necessary to extend or retract the data cable to adjust its length during use. To solve this problem, extendable data cables have appeared on the market. However, most current extendable data cables only have the extension function, which is relatively simple and does not bring more convenience to users.

[0004] In view of this, it is necessary to propose further improvements to the current retractable data cable. Utility Model Content

[0031] Please refer to Figures 1 to 9This utility model provides a multi-functional retractable data cable, including a base 1 and a luminous component 2. The base 1 and the luminous component 2 are connected to each other to form a receiving space. The receiving space contains a winding component 3. A wireless charging component 4 can be detachably connected to the side of the luminous component 2 away from the base 1. The winding component 3 includes a data cable 31. The data cable 31 is electrically connected to the luminous component 2 and the wireless charging component 4 through an adapter 33.

[0032] In this embodiment, the multi-functional retractable data cable includes a base 1 and a luminous component 2. The base 1 and the luminous component 2 are connected to form a receiving space, that is, the base 1 is the bottom shell and the luminous component 2 is the cover, and the two are connected to form a receiving space. A cable winding assembly 3 is installed in this receiving space. The cable winding assembly 3 includes a data cable 31. When needed, the data cable 31 can be stretched and extended, so that the length of the data cable 31 is adjustable, making it more convenient to use.

[0033] The luminous component 2 provides a certain luminous function, serving as illumination and warning. One side of the luminous component 2 is connected to the base 1 to form a space for accommodating the cable reel component 3, while the other side is detachably connected to the wireless charging component 4. Electronic devices with different interface types can be wirelessly charged by placing them on the wireless charging component 4. Specifically, an adapter 33 is connected to the data cable 31. In this embodiment, the adapter 33 is a PCB adapter board. The data cable 31 connects to the power line and signal line through the PCB adapter board, thereby electrically connecting to the luminous component 2 and the wireless charging component 4. This allows the data cable 31 to supply power to the luminous component 2 and the wireless charging component 4 through the adapter 33, giving the multi-functional retractable data cable both luminous and wireless charging functions. This solves the problem that existing data cables have relatively simple functions, cannot meet the daily needs of users, and reduce the practicality of data cables.

[0034] Furthermore, the data cable 31 includes a first cable body 311 and a second cable body 312. The first cable body 311 and the second cable body 312 are connected by an adapter 33. The adapter 33 is also provided with a lead wire 331 on the side away from the first cable body 311 and the second cable body 312, and is electrically connected to the luminous component 2 and the wireless charging component 4 through the lead wire 331.

[0035] In this embodiment, the data cable 31 includes two parts: a first cable body 311 and a second cable body 312. One end of the first cable body 311 and the second cable body 312 are electrically connected through an adapter 33, or they can be connected by a splice. The other end can be a Micro-USB interface, a USB-C interface, a Lightning interface, or a USB interface, respectively, for connecting electronic devices with different interfaces or connecting to a power source.

[0036] Specifically, one side of the adapter 33 is connected to the first wire 311 and the second wire 312, while the other side is connected to the lead wire 331. The lead wire 331 is electrically connected to the luminous component 2 and the wireless charging component 4, so that the data cable 31 can not only charge the electronic device while connected to the power source, but also supply power to the luminous component 2 and the wireless charging component 4. Thus, the multi-functional retractable data cable also has the functions of luminous and wireless charging.

[0037] Furthermore, the cable winding assembly 3 also includes a cable winding spool 32, on which the data cable 31 is wound. The cable winding spool 32 is provided with a first PCB 34 on the side near the luminous component 2, and also has an opening 321. The lead wire 331 passes through the opening 321 and connects to the first PCB 34.

[0038] In this embodiment, the cable winding assembly 3 includes a cable reel 32, on which the data cable 31 is wound. The cable reel 32 is used to store and extend the data cable 31, allowing the data cable 31 to be freely stretched or retracted on the cable reel 32. A first PCB 34 is disposed on the side of the cable reel 32 near the luminous component 2, and an opening 321 is also provided on the side of the cable reel 32 where the first PCB 34 is disposed, so that the lead wire 331 on the connector 33 can pass through the opening 321 and be electrically connected to the first PCB 34, that is, the external power supply of the data cable 3 can supply power to the first PCB 34. The first PCB 34 is also provided with a slot adapted to connect with the lead wire 331, so that the adapter 33 can be better connected to the first PCB 34.

[0039] Furthermore, the luminous component 2 includes a housing 21 and a second PCB 22 that are interlocked. The second PCB 22 has at least two mounting holes for connecting spring terminals 221. The side of the spring terminals 221 closest to the first PCB 34 abuts against the first PCB 34. The side of the second PCB 22 away from the first PCB 34 is also provided with multiple probes 222. The housing 21 has multiple locking holes 212 that are adapted to the probes 222. The probes 222 pass through the locking holes 212 and connect to the wireless charging component 4. The second PCB 22 is also provided with multiple light-emitting elements 223 and switching elements 224, and the switching elements 224 are exposed outside the housing 21.

[0040] In this embodiment, the first PCB 34 is connected to the data line 31 via lead wire 331 and connector 33, allowing the data line 31 to be connected to an external power source to power the first PCB 34. Furthermore, the first PCB 34 and the second PCB 22 are electrically connected via spring contact terminals 221. Specifically, the first PCB 34 has a copper foil on the side closest to the second PCB 22, and the second PCB 22 has mounting holes for connecting the spring contact terminals 221. The spring contact terminals 221 pass through these mounting holes and are mounted on the second PCB 22, allowing the side of the spring contact terminals 222 closest to the first PCB 34 to rotate and rub against the copper foil on the first PCB 34, thus conducting electricity. In other words, the first PCB 34 and the second PCB 22 conduct electricity through the rotational friction of the spring contact terminals 221.

[0041] In this embodiment, the second PCB 22 near the housing 21 is provided with a plurality of metal probes 222, and the housing 21 is provided with a plurality of slots 212 adapted to the probes 222. The probes 222 connected to the second PCB 22 pass through the slots 212 to connect to the wireless charging component 4 provided on the housing 21, so that the data cable 31 and the wireless charging component 4 are connected through the first PCB 34 and the second PCB 22 to achieve smooth conductivity, thereby enabling the data cable 31 to supply power to the wireless charging component 4. That is, the data cable 31 is electrically connected to the first PCB 34 through the PCB adapter board, the first PCB 34 is electrically connected to the second PCB 22 through the rotational friction of the spring contact terminal 222, and the second PCB 22 is electrically connected to the wireless charging component 4 through the metal probes 222 to realize the wireless charging function.

[0042] In this embodiment, the light-emitting element 223 can specifically be a light-emitting LED, and the specific model is not limited. The light-emitting element 223 can be controlled to turn on and off by the switch element 224. The light-emitting element 223 is specifically a button. A hole adapted to the button is provided on the housing 21, so that the button can be exposed on the housing 21 through the hole, allowing the user to press the button more conveniently to control the light-emitting element 223. In this embodiment, the housing 21 is specifically an LED light cover.

[0043] Furthermore, a plurality of first limiting posts are provided on the side of the housing 21 near the second PCB 22, and a plurality of first limiting grooves adapted to the first limiting posts are also provided on the second PCB 22. The second PCB 22 is connected to the housing 21 through the first limiting grooves. A groove 211 with a plurality of card holes 212 is also provided on the side of the housing 21 away from the second PCB 22. A wireless charging component 4 is detachably connected in the groove 211.

[0044] In this embodiment, the luminous component 2 includes a housing 21 and a second PCB 22. The housing 21 covers the base 1, thereby forming a receiving space for accommodating the winding assembly 3. The second PCB 22 is disposed between the winding assembly 3 and the housing 21. The housing 21 is also provided with a plurality of first limiting posts on the side near the winding assembly 3. The second PCB 22 is provided with a plurality of first limiting grooves. The number and shape of the first limiting grooves are adapted to the number and shape of the first limiting posts, so that the second PCB 22 can be connected to the housing 21 through the first limiting grooves to fix the second PCB 22 and prevent the second PCB 22 from shaking arbitrarily.

[0045] Among them, a groove 211 is provided on the side of the housing 21 away from the winding assembly 3. Multiple slots 212 are provided in the groove 211. A wireless charging assembly 4 is detachably connected in the groove 211 so that the probe 222 on the second PCB 22 can pass through the slots 212 in the groove 211 and be electrically connected to the wireless charging assembly 4 in the groove 211.

[0046] Furthermore, the wireless charging assembly 4 includes a wireless charging cover 41 and a third PCB 42 that are interlocked with each other. The probe 222 passes through the card hole 212 in the groove 211 and abuts against the third PCB 42. The third PCB 42 is provided with a wireless charging coil 421 and a second limiting groove. The wireless charging cover 41 is provided with a second limiting post that is adapted to the second limiting groove. The third PCB 42 is connected to the wireless charging cover 41 through the second limiting groove.

[0047] In this embodiment, the groove 211 is provided with a plurality of card holes 212 adapted to the probe 222. The probe 222 connected to the second PCB22 passes through the card holes 212 in the groove 211 and is electrically connected to the third PCB42, so that the data line 31 supplies power to the third PCB42 through the first PCB34 and the second PCB22 to realize the function of wireless charging.

[0048] In this embodiment, the wireless charging component 4 includes a wireless charging cover 41 and a third PCB 42. Electronic devices can be placed on the wireless charging cover 41, and the third PCB 42 charges the electronic devices placed on the cover 41. Specifically, the wireless charging cover 41 is detachably connected to the groove 211, forming a receiving space. The third PCB 42 is disposed within this receiving space. At least two second limiting posts are provided on the side of the wireless charging cover 41 near the luminous component 2, and at least two second limiting grooves adapted to the second limiting posts are provided on the third PCB 42. This allows the third PCB 42 to be connected to the wireless charging cover 41, preventing it from shaking and enabling it to better charge the electronic devices placed on the cover 41. The third PCB 42 is provided with a wireless charging coil 421 for wireless charging.

[0049] Furthermore, an aromatherapy component 5 can be detachably connected to the groove 211. The aromatherapy component 5 includes an aromatherapy cover 51 and an aromatherapy diffuser 52. The aromatherapy cover 51 covers the aromatherapy diffuser 52 and is detachably connected to the groove 211. The aromatherapy cover 51 has multiple through holes for emitting aromatherapy fragrance. Specifically, the groove 211 can not only connect to the wireless charging component 4, but also remove the wireless charging component 4 and replace it with the aromatherapy component 5, which is placed in the groove 211 of the luminous component 2. The aromatherapy component 5 serves to purify the air and promote relaxation.

[0050] Furthermore, the base 1 has two through holes 11 and a positioning member 12. The relatively far ends of the first wire 311 and the second wire 312 pass through the through holes 11 and are exposed on the base 1. The data cable 3, which is wound on the reel 32, can be pulled out by pulling the connector of the first wire 311 or the second wire 312 exposed in the through hole, making it convenient for users to use. This allows the first wire 311 and the second wire 312 to be connected to an external power source and used to charge electronic devices.

[0051] Furthermore, the cable winding assembly 3 includes an elastic element disposed within the cable winding reel 32. The cable winding reel 32 is rotatably connected to the positioning member 12. The two ends of the elastic element are respectively connected to the cable winding reel 32 and the positioning member 12. The elastic element can drive the cable winding reel 32 to rotate relative to the positioning member 12 to achieve the retraction of the data cable 31.

[0052] In this embodiment, the two ends of the elastic element are connected to the cable reel 32 and the positioning element 12, respectively. When the data cable 3 is pulled out, the cable reel 32 rotates relative to the positioning element 12, causing the elastic element to deform and generate elastic force. When the user is not using the cable, the elastic force of the elastic element causes the cable reel 32 to rotate in the opposite direction to reset, thereby retracting the data cable 3 for easy organization. In this embodiment, the elastic element is specifically a spring sheet, but the specific type of elastic element is not limited and can be set according to actual production needs.

[0053] Furthermore, the reel 32 is provided with a track 35 for telescopic positioning on the side near the luminous component 2. The side of the luminous component 2 opposite to the track 35 is provided with a straight groove, and a ball bearing is provided in the straight groove. Part of the ball bearing is provided in the straight groove, and the other part is provided in the track 35. When the reel 32 rotates relative to the positioning member 12, the ball bearing rotates in the track 35 to realize the telescopic positioning of the data cable 31.

[0054] In this embodiment, a straight groove is provided on the housing 21 of the luminous component 2. Part of the ball bearing is disposed in the straight groove, and the other part is disposed in the track 35. When the data cable 3 is pulled, the winding reel 32 rotates relative to the positioning member 12, and the track on the winding reel 32 also rotates accordingly. The ball bearing also rotates relative to the positioning member. The track 35 is designed with multiple grooves or notches. When the data cable 3 is stretched to a certain length, the ball bearing will be inserted into the corresponding groove as it rolls, so that the data cable 3 is temporarily stopped at that position. This allows the user to stretch the data cable 3 to different lengths as needed, and forms a self-locking state, so that the data cable is kept at that length and will not automatically retract due to external force, which is convenient to use. When it is necessary to retract the data cable 3, the user only needs to gently pull the data cable 3 to disengage the ball bearing from the groove. The data cable 3 will automatically retract under the action of the internal elastic member. The grooves on the track 35 can limit the maximum stretching length of the data cable 3, preventing the data cable 3 from being overstretched and damaged.

[0055] Furthermore, the specific connection structure of the first PCB34, the second PCB22, and the third PCB42 in this embodiment of the application is as follows:

[0056] The data cable 31 is connected to the first PCB 34 via a splice or a PCB adapter board (connector 3). The first PCB 34 has copper foil. The spring terminal 221 on the second PCB 22 rubs against the copper foil on the first PCB 34 during rotation, thereby making contact and connecting with the second PCB 22. The second PCB 22 is also provided with multiple metal probes 222, which abut against the third PCB 42 to connect the second PCB 22 and the third PCB 42. Thus, the data cable 31 can supply power to the first PCB 34, the second PCB 22, and the third PCB 42 when an external power source is connected. This allows the multi-functional retractable data cable to not only charge electronic devices but also have the functions of night light and wireless charging.

[0057] This utility model provides a multi-functional retractable data cable, including a base and a luminous component. The base and the luminous component are interconnected to form a receiving space, which houses a cable winding assembly. A wireless charging assembly is detachably connected to the side of the luminous component away from the base. The cable winding assembly includes a data cable, which is electrically connected to the luminous component and the wireless charging assembly via an adapter. The multi-functional retractable data cable provided by this utility model allows for cable retraction and extension via the cable winding assembly. Furthermore, this multi-functional retractable data cable powers the luminous component and the wireless charging assembly through the data cable, and also provides the functions of emitting light and wirelessly charging electronic devices. This solves the problem that existing data cables have limited functionality, failing to meet users' daily needs and reducing their practicality.
