The wire 6a of the coil 6 passes through the wire hole of the front plate 7, is located in the wire groove 3c of the telescopic bracket 3, and passes through the base 1 or the front cover 2 to connect to the external circuit.

[0031] When this vehicle-mounted wireless charging device wirelessly charges a mobile phone P, it generally involves the following steps:

[0032] Step 1 – Release the chuck mechanism

[0033] In practical use, when it is necessary to wirelessly charge a mobile phone P using the vehicle-mounted wireless charging device of this utility model, and the claw mechanism is in a certain position... Figure 7 ( Figure 8 In the non-released state shown, the motor 14 that controls the start of the rotation mechanism drives the drive wheel 15 to perform the following actions: Figure 7The counterclockwise rotation shown starts from 0 degrees and proceeds 22 degrees. Passing through the step 15c at one end of the track groove 15b on the drive wheel 15, it drives the chuck 11a, causing the transmission rod 11 to overcome the spring force of the spring 13 and slide outwards. The chuck 11a and the transmission rod 11 move outwards a small distance (approximately 7mm in this embodiment). The transmission rod 11 of the chuck mechanism drives the chuck 10, placing it in a position as shown... Figure 9 The state shown is the loosened state.

[0034] Step Two – Extend the Telescopic Mechanism

[0035] Then, if the drive wheel 15 continues to rotate counterclockwise from 22 degrees to the final 80 degrees, the transmission rod 11 of the claw mechanism is constrained by the transmission groove of the rear plate 12, and its locking head 11a is controlled by the track groove 15b to keep the transmission rod 11 stationary. During this process, the drive wheel 15 connects to the locking hole of the cam 8 through the locking post 15a, driving the cam 8 to rotate, and through the protrusion 8a of the cam 8 and the groove 3b of the telescopic bracket 3 of the telescopic mechanism, pushes the telescopic bracket 3 and the plate 4 to extend, as shown. Figure 11 As shown, this makes it easy to pick up and put down the phone.

[0036] Step 3 – Start the charging mechanism

[0037] Next, place the phone P in such a position. Figure 4 or Figure 11 At the location shown in the sticker 4, the magnetic ring 5 corresponds to the magnetic ring inside the mobile phone P, which attracts the mobile phone P to the sticker 4, and the wireless charging mechanism can then start charging the mobile phone.

[0038] Step Four – Retracting the Telescopic Mechanism

[0039] When the phone P is attached to the mounting plate 4, the starting motor 14 drives the drive wheel 15 to perform... Figure 7 The clockwise rotation from the final position of 80 degrees to 22 degrees is shown. The transmission rod 11 and the locking pin 15a of the claw mechanism are fixed by the track groove 15b. During this process, the drive wheel 15 is connected to the locking hole of the cam 8 through the locking pin 15a, which drives the cam 8 to rotate. The drive wheel 15 is pushed to retract through the protrusion 8a of the cam 8 and the groove 3b of the telescopic bracket 3.

[0040] Step 5 – Clamping the jaw mechanism

[0041] When the telescopic mechanism retracts, the drive wheel 15 continues to rotate clockwise from 22 degrees to the initial 0 degrees. At this point, the spring 13 pushes the transmission rod 11 to slide inward, causing the claw mechanism to be in the position described above. Figure 7 ( Figure 8 As shown in the diagram, the latch 10 engages with the slot P1 of the phone P, securely locking the phone P in place. Figure 10As shown, the outer edge of the screen of the mobile phone P is basically flush with the front edge of the front cover 2.

[0042] Step Six – Retrieving and Placing the Phone

[0043] Once charging is complete, simply go through step one – releasing the clasp mechanism – and step two – extending the telescopic mechanism to easily pick up and put down the phone P.

[0044] The above description is only a general embodiment of this utility model. For those skilled in the art, there are various other embodiments with modifications and variations, which will not be elaborated here. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model are included within the protection scope claimed by this utility model.
