Description

Technical Field

[0001] This utility model relates to the field of magnetic chargers, and in particular to a foldable three-in-one magnetic charger. Background Technology

[0002] Traditional wireless chargers can typically only charge one type of electronic device. If you need to charge multiple electronic devices at the same time, you need to have multiple wireless chargers, which is inconvenient when you go out.

[0003] Currently, a three-in-one wireless charging device has emerged on the market that can wirelessly charge various electronic products such as Apple iPhones, Apple earphones, and Apple Watches. This type of three-in-one wireless charging device generally includes a support frame, a first wireless charging module for wirelessly charging the first type of electronic product (e.g., Apple earphones), a second wireless charging module for wirelessly charging the second type of electronic product (e.g., Apple iPhones), and a third wireless charging module for wirelessly charging the third type of electronic product (e.g., Apple Watches). The bottom of the support frame is fixedly mounted on top of the first wireless charging module. The second wireless charging module is rotatably mounted on top of the support frame. A connecting frame is fixedly mounted on one side of the support frame, below the second wireless charging module, and perpendicular to the support frame. The third wireless charging module is fixedly mounted on the end of the connecting frame furthest from the support frame. While this type of charger can meet the charging needs of various electronic products, its support frame is fixed at the top of the first wireless charging module, and the connecting frame is perpendicular to the support frame. The support frame cannot be folded onto the first wireless charging module, and the connecting frame cannot be folded onto the support frame. Furthermore, the height of the support frame is usually greater than the length of the mobile phone, resulting in a relatively tall charger with a large volume, which takes up a lot of space and is inconvenient to carry and store.

[0004] Therefore, a new technical solution needs to be researched to address the above problems. Utility Model Content

[0066] Preferably, the second rotating member 31 is also provided with a wire-passing hole 33. The design of the wire-passing hole 33 provides a wire-passing position for the coil of the third wireless charging coil module, so that the coil of the third wireless charging coil module will not break during the extension and retraction of the second charging base 30 relative to the second rotating member 31.

[0067] Preferably, the second charging base 30 includes a housing 34, and a mating plate 35 is further provided inside the housing 34. The mating plate 35 and the inner side surface of the housing 34 form a sliding groove 36. A plurality of abutment grooves 341 are provided at intervals on the side of the housing 34 near the sliding groove 36. A ball bearing assembly 37 is provided on the side of the second rotating member 31 near the abutment grooves 341. The ball bearing assembly 37 includes a ball head 371 and an elastic reset member 372. The lower end of the ball head 371 is connected to... The upper end of the elastic reset member 372; the second rotating member 31 can slide into the sliding groove 36, and the upper end of the ball head 371 protrudes from the top of the second rotating member 31 and is restricted in the abutment groove 341, so that the second rotating member 31 and the second charging base 30 are locked together; the mating plate 35 is provided with a plurality of elastic arms 351 at intervals on the side near the abutment groove 341; the second rotating member 31 can slide into the sliding groove 36, and part of the second rotating member 31 abuts against the elastic arms 351. By utilizing the cooperation between the ball assembly 37, the abutment groove 341, the elastic arms 351, and the second movable plate 312 described below, when the second charging base 30 slides and extends to the selected position, a double lock is formed on the second charging base 30 to prevent the second charging base 30 from sliding and affecting the charging of the electronic device during subsequent use.

[0070] Preferably, the second charging base 30 is further provided with a second upper shell, a second magnet, a third magnetic attraction module and a third wireless charging coil module. The second upper shell covers the housing 34 to form a third mounting cavity. The housing 34 is also provided with a clearance hole.

The coil of the third wireless charging coil module passes through the clearance hole and the wire hole 33 in sequence, extends into the charging base 10 and is electrically connected to the PCB board.

[0071] In this embodiment, the first wireless charging coil module, the second wireless charging coil module, and the third wireless charging coil module can be connected to the PCB board via FPC flexible board, solder joints, or connectors. When soldering the solder joints, the positive terminal, negative terminal, and feedback pin of the first wireless charging coil module, the second wireless charging coil module, and the third wireless charging coil module can be soldered to the PCB board.

[0072] Secondly, the parameters of the current-limiting resistors (e.g., 10Ω / 1W resistance) and the specifications of the filter capacitors (e.g., 100μF / 16V) between each wireless charging coil module and the PCB board are important. This ensures stable coil current and avoids current fluctuations affecting charging efficiency.

[0073] The PCB board integrates overcurrent protection, overvoltage protection, and short-circuit protection circuits to ensure the safety and stability of the charging process. To reduce electromagnetic interference, a shielding layer or shielding cover can be set on the PCB board. The integration of overcurrent protection, overvoltage protection, and short-circuit protection circuits on the PCB board, as well as the setting of a shielding layer or shielding cover on the PCB board, are all existing technologies known in the art and will not be elaborated here.

[0074] In this embodiment, the specific measures for the PCB board are as follows:

[0075] Overcurrent protection: A resettable fuse (model such as JK60-010, rated current 1A) is connected in series in the main power circuit of the PCB board. When the circuit current exceeds 1.5A, the fuse will automatically trip and automatically reset after the current returns to normal.

[0076] Overvoltage protection: A transient voltage suppressor diode (TVS) (model such as SMBJ5.0CA, breakdown voltage 5V) is connected in parallel in the power supply branch of each wireless charging coil to prevent voltage spikes from damaging the wireless charging coil.

[0077] Short circuit protection: The short circuit detection circuit on the PCB board (composed of a comparator LM393 and a sampling resistor) detects a short circuit in the wireless charging coil. When this short circuit is detected, the comparator outputs a signal that triggers the main control chip (such as an STM32F030) to cut off the power supply line of the corresponding branch. The main control chip can be integrated on the PCB board or set up separately.

[0078] Over-temperature protection: A thermistor (model such as MF52-10K) is installed on the PCB board near the wireless charging coil. It is specified that when the detected temperature exceeds 65℃, the main control chip reduces the charging power to 5W, and stops charging when it exceeds 70℃.

[0079] The PCB board can adopt a double-layer board design, with the power circuit and signal circuit laid out separately to avoid electromagnetic interference; key protection components (fuse, TVS diode) are close to the power input terminal to shorten the protection path. The electrical connection method and circuit protection measures between the above PCB board and each charging coil module are well known technologies in the field and will not be described in detail here.

[0080] like Figures 9 to 10 As shown, the structure of the second embodiment is disclosed:

[0081] The plurality of elastic arms 351 are movably mounted on the second movable plate 312. Each elastic arm 351 includes a connecting arm 352 and a connecting protrusion 353, with the connecting protrusion 353 extending from one side of the connecting arm 352. The second movable plate 312 has a plurality of mating grooves 315 on one side facing the plurality of elastic arms 352 for engaging with the connecting protrusion 353. The second rotating member can slide into the sliding groove, and the connecting protrusion 353 is adapted to the mating groove 315. Through the design of the connecting protrusion and the mating groove, when the second charging base 30 slides to the selected position, it is locked to prevent the second charging base 30 from sliding and affecting the charging of the electronic device during subsequent use.

[0082] The key design feature of this utility model is that it enables wireless charging of three types of electronic products through the structural design between the charging base, the first charging base, and the second charging base, thereby meeting the charging needs of various electronic products.

[0083] Secondly, the first charging dock can be selectively rotatably connected to one end of the charging base via the first rotating component, so that the first charging dock can be closed or moved away from one end of the charging base; the other end of the second rotating component can be selectively rotatably connected to the other end of the charging base, so that the second charging dock can be retracted to close or extended away from the other end of the charging base; thus, when not in use, the first charging dock can be folded and stored at the bottom of the charging base, and the second charging dock can be retracted to close on the charging base, thereby reducing the overall size of the magnetic charger;

[0084] In addition, the second charging dock is designed to be retractable at one end of the second rotating component. This allows for adjustment of the distance between the second charging dock and the charging base, enabling it to charge various types of mobile phones and preventing subsequent charging issues caused by the distance between the second charging dock and the charging base.

[0085] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
