Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0036] The utility model provides Figure 1-4 A wireless charging coil assembly shown includes a fixing plate 1 and a copper coil 2 arranged at the front side of the fixing plate 1;

[0037] A front head 4 is arranged at the head end of the copper coil 2, a tail head 3 is arranged at the tail end of the copper coil 2, and connectors 5 are arranged at the outer positions of the front head 4 and the tail head 3 respectively;

[0039] In this embodiment, the principle of use

[0040] The operating principle of the wireless charging coil assembly is based on electromagnetic induction technology. When the copper coil 2 is energized, an alternating magnetic field is generated. When the coil at the other receiving end (i.e., the coil assembly in the charged device) is close to this magnetic field, due to the effect of electromagnetic induction, a current will be generated in the coil at the receiving end, thereby realizing wireless energy transmission. This design achieves effective fixation and adjustment of the copper coil 2 through the combination of the fixing plate 1, the fixing ring 8, the threaded rod 6, the threaded ring 7 and the embedded groove 9, so that the coil can be arranged according to a specific arrangement and diameter change to optimize the charging efficiency and adapt to receiving devices of different sizes.

[0041] How to use

[0042] Preparation: First, make sure that all components (fixing plate 1, copper coil 2, front head 4, tail head 3, connector 5, fixing ring 8, threaded rod 6, threaded ring 7, embedded groove 9, etc.) are complete and undamaged.

[0043] Assemble the coil: Connect the head end and tail end of the copper coil 2 to the front head 4 and the tail head 3 respectively, and then fix the connector 5 to the outside of the front head 4 and the tail head 3 by gluing.

[0044] Install the coil: Pass the copper coil 2 through the groove 9 on the threaded ring 7 outside the fixing ring 8, so that the copper coil 2 forms a nested ring, and the diameter of each turn of the ring increases gradually.

[0045] Fix the coil: By rotating the threaded ring 7, it moves back and forth along the threaded rod 6, and adjust the position of the coil until the coil is firmly fixed and arranged neatly.

[0046] Connect power: Connect connector 5 to a suitable power source, making sure copper coil 2 is powered.

[0047] Place the receiving device: Place the wireless device to be charged above the coil assembly, making sure the receiving coil in the device is aligned with the magnetic field generated by copper coil 2.

[0048] Start charging: Turn on the power, and the copper coil 2 starts working, generating an alternating magnetic field. The coil in the receiving device senses the magnetic field and generates current, thus starting the wireless charging process.

[0049] Monitor charging status: During the charging process, the charging status and device temperature should be checked regularly to ensure that the charging process is safe and effective.

[0050] Through the above steps, the wireless charging coil assembly can effectively provide convenient charging services for wireless devices. It should be noted that the product manual and relevant safety regulations should be followed during actual operation to ensure safe use and charging efficiency.

[0051] like Figure 1-4 As shown, the threaded rod 6 is connected to the fixing ring 8 by an integrated connection method, the fixing ring 8 is connected to the fixing plate 1 by a glue adhesion connection method, the threaded ring 7 is connected to the threaded rod 6 by a threaded connection method, and the threaded ring 7 can be rotated and moved forward and backward on the threaded rod 6 by a thread, the copper coil 2 is connected to the threaded ring 7 by penetrating the embedding groove 9, there are six threaded rods 6, and the six threaded rods 6 are equidistantly arranged on the outside of the fixing ring 8, the copper coil 2 forms a nested circular ring by a plurality of embedding grooves 9 penetrating the plurality of threaded rings 7, and the diameter of each turn of the circular ring increases successively, the connector 5 is connected to the tail head 3 and the front head 4 of the copper coil 2 by a glue adhesion connection method, and a mounting groove 10 is provided at the middle position of the upper side of the fixing plate 1.

[0052] Preferably, the operator can move the threaded ring 7 on the threaded rod 6 by rotating the threaded ring 7 using the thread. The multi-turn copper coil 2 is connected to the threaded ring 7 by passing through the groove 9 on the lower side of the threaded ring 7. When the threaded ring 7 changes its distance on the threaded rod 6, it can drive the diameter of the multi-turn copper coil 2 to change, thereby changing the volume of the multi-turn copper coil 2. After the volume of the copper coil 2 of the coil assembly is enlarged, it can be used to adapt to different charging tools.

[0053] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
