[0025] The present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0026] See Figures 1 to 8 As shown, a multi-functional car charger includes: a power supply unit 1 for connecting to a car cigarette lighter; and a charging base 2 detachably mounted on the power supply unit 1. The power supply unit 1 includes a power base 11 and a swing bracket 12 swayably mounted on the power base 11 and connected to the charging base 2. The power base 11 has a first charging interface 111. The charging base 2 has a wireless charging surface 21 for wirelessly charging smart devices and a retractable data cable 22 for wired charging of smart devices. When the charging base 2 is separated from the power supply unit 1 and the retractable data cable 22 is connected to the first charging interface 111, the electrical energy from the car cigarette lighter is transferred to the charging base 2, enabling the wireless charging surface 21 to wirelessly charge smart devices.

[0027] In this invention, a swing bracket 12 is provided on the power base 11, and the charging base 2 is installed on the swing bracket 12, allowing the charging base 2 to adjust its angle with the swing bracket 12, effectively improving adaptability and making it applicable to various vehicle chargers. Furthermore, compared to existing structures, the charging base 2 and the power unit 1 in this invention are detachable. After separation, when the retractable data cable 22 is connected to the first charging interface 111, the wireless charging surface 21 can wirelessly charge smart devices, adding a new wireless charging method and solving the problem of inconvenience in using mobile phones while wirelessly charging, effectively enhancing product competitiveness.

[0028] The power supply unit 1 is also provided with several second charging ports 16, wherein the first charging port 111 is a Type-C port and the second charging port is a USB port. The swing bracket 12 is provided with several first magnetic components 121, and the lower end face of the charging base 2 is provided with several second magnetic components 122 for magnetic attraction with the first magnetic components 121. The swing bracket 12 is provided with a conductive spring pin assembly 4, and correspondingly, the charging base 2 is provided with a conductive spring sheet assembly 5. When the charging base 2 is magnetically attracted to the swing bracket 12, the conductive spring pin assembly 4 is inserted into the conductive spring sheet assembly 5, so that the power supply unit 1 can transfer electrical energy to the charging base 2. Here, in conjunction with... Figure 8As shown, when the charging base 2 is magnetically attached to the swing bracket 12, the swing bracket 12 can be swung outward to expose the first charging port 111 and the second charging port 16 on the power base 11, which is the "flipped state". At this time, the user can charge multiple smart devices at the same time through the retractable data cable 22, the first charging port 111, the second charging port 16 and the wireless charging surface 21. Moreover, the charging methods cover multiple methods such as Type-C interface, USB interface and wireless, which can meet the user's "one-charge-multiple-use" needs.

[0029] The lower end face of the charging base 2 has a protruding sleeve edge 201 with a clearance groove 2011. Correspondingly, the swing bracket 12 has a protruding locking protrusion 1211. When the charging base 2 is magnetically attached to the swing bracket 12, the sleeve edge 201 is fitted around the swing bracket 12 to prevent the charging base 2 from accidentally slipping off, and the locking protrusion 1211 is engaged in the clearance groove 2011 to prevent the charging base 2 from rotating circumferentially. Here, to ensure the charging base 2 remains stable during wireless charging, the sleeve edge 201 is fitted around the swing bracket 12, forming an axial force, which effectively prevents the charging base 2 from accidentally sliding when the user picks up the smart product. At the same time, the locking protrusion 1211 is engaged in the clearance groove 2011 to prevent the charging base 2 from sliding circumferentially, further improving stability.

[0030] The retractable data cable 22 includes a cable body 221 retractably disposed within the charging base 2 and a charging port 222 connected to the cable body 221 and located outside the charging base 2. The charging base 2 includes a housing 210, a winding turntable 220 disposed within the housing 210 for storing the cable body 221, a turntable bracket 230 disposed within the housing 210 for supporting the winding turntable 220, a PCB board 240 disposed below the winding turntable 220 for connecting to the conductive spring assembly 5, and a coil assembly 250 disposed above the winding turntable 220 for wireless charging. The housing 210 includes a lower housing 260 and an upper housing 270 covering the lower housing 260. Here, the cable body 221 of the retractable data cable 22 is stored inside the charging base 2 via the winding turntable 220. When needed, it can be manually pulled outward by pinching the charging port 222.

[0031] The swing bracket 12 includes a connector 123 that is swingably connected to the power base 11 and a bracket body 124 mounted on the connector 123 and used for connection with the charging base 2. The power base 11 has a mounting groove 112 for mounting the swing bracket 12, and the connector 123 fits into the mounting groove 112. The connector 123 has a protruding pivot shaft 1231, and correspondingly, the mounting groove 112 has a pivot hole 1232 for pivoting the pivot shaft 1231. The connector 123 has a first tooth 1233, and the bottom of the mounting groove 112 has an upwardly protruding elastic tooth 1121 for engaging with the first tooth 1233 to increase damping. Here, when the swing bracket 12 is manually moved, the first tooth 1233 at the lower end of the connector 123 will rotate and contact the elastic protrusion 1121. When the angle is adjusted to a suitable position and the movement is stopped, the elastic protrusion 1121 will engage in the gap between the teeth of the first tooth 1233, so that the swing bracket 12 can maintain the angle and achieve a damping effect.

[0032] The swing bracket 12 is provided with a first clearance hole 1201 for the first charging interface 111 to be exposed outward, and the swing bracket 12 is also provided with a second clearance hole 1202 for the second charging interface 16 to be exposed outward.

[0033] Combination Figure 2 and Figure 7 As shown, in one embodiment of this utility model, the charging base 2 is separated from the swing bracket 12 of the power supply unit 1, and after separation, the retractable data cable 22 is connected to the first charging interface 111. At this time, the electrical energy of the car cigarette lighter is transferred to the charging base 2, so that the wireless charging surface 21 can provide wireless charging for smart devices, which is the "split state". The charging base 2 can be attached to various magnetically attractive positions by the second magnetic member 122. For example, a magnetic plate 70 can be set at the air conditioning vent of the car to extend the charging base 2 to the air conditioning vent, which meets the user's usage mode such as charging and navigation at the same time, adds a new wireless charging method, and solves the problem of inconvenience in using mobile phones while wirelessly charging.

[0034] In summary, by setting a swing bracket 12 on the power base 11 and mounting the charging base 2 on the swing bracket 12, the charging base 2 can adjust its angle with the swing bracket 12, effectively improving its adaptability and making it applicable to various vehicle chargers. Furthermore, compared to existing structures, the charging base 2 and the power unit 1 in this invention are detachable. After separation, when the retractable data cable 22 is connected to the first charging interface 111, the wireless charging surface 21 can wirelessly charge smart devices, adding a new wireless charging method and solving the problem of inconvenience in using mobile phones while wirelessly charging, effectively enhancing the product's competitiveness.
