[0014] When you need to wirelessly charge your phone using the in-car wireless charging device
[0015] Step 1 – Release the chuck mechanism
[0016] The motor that starts the rotating mechanism drives the drive wheel to rotate counterclockwise, from the initial 0 degrees to 22 degrees. Passing through the step at one end of the track groove on the drive wheel, it drives the chuck to make the transmission rod overcome the spring force and slide outward. The chuck and the transmission rod move outward a short distance. The transmission rod of the chuck mechanism drives the chuck to be in the released state.
[0017] Step Two – Extend the Telescopic Mechanism
[0018] If the drive wheel continues to rotate counterclockwise from 22 degrees to the final 80 degrees, the transmission rod of the claw mechanism is constrained by the transmission groove of the rear plate, and its chuck head is controlled by the track groove to keep the transmission rod stationary. During this process, the drive wheel drives the cam to rotate through the chuck hole of the cam connected by the chuck post, and pushes the telescopic bracket and the plate out through the cam's protrusion and the groove of the telescopic bracket of the telescopic mechanism, making it easier to pick up and put down the mobile phone.
[0019] Step 3 – Start the charging mechanism
[0020] Next, place your phone on the charging mechanism, and the wireless charging mechanism will begin charging your phone.
[0021] Step Four – Retracting the Telescopic Mechanism
[0022] When the mobile phone is placed on the charging mechanism, the motor drives the drive wheel to rotate clockwise from 80 degrees to 22 degrees. The transmission rod and the locking pin of the claw mechanism are fixed by the track groove. During this process, the drive wheel drives the cam to rotate through the locking pin and the locking hole of the cam. The cam's protrusion and the groove of the telescopic bracket push the telescopic bracket to retract.
[0023] Step 5 – Clamping the jaw mechanism
[0024] When the telescopic mechanism retracts, the drive wheel continues to rotate clockwise from 22 degrees to the initial 0 degrees. The spring push transmission rod slides inward, so that the claw mechanism is in the clamping state shown. The claws are engaged in the mobile phone slot, which securely locks the mobile phone and makes the outer edge of the screen of the mobile phone flush with the front edge of the front cover.
[0025] Step Six – Retrieving and Placing the Phone
[0026] 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 your phone.
[0027] The charging mechanism includes a mounting plate, a magnetic ring, and a coil. The coil is connected to a lead wire. The magnetic ring and the coil are fixedly installed on the rear side of the mounting plate and together on the front plate, so that the mounting plate is located at the phone window part of the front cover. The lead wire of the coil passes through the lead wire hole of the front plate, is located in the lead wire groove of the telescopic bracket, and passes through the base or the front cover to connect to the external circuit.
[0028] In step three – activating the charging mechanism, the phone is placed on the mounting plate of the charging mechanism. The magnetic ring, corresponding to the magnetic ring inside the phone, attracts the phone to the mounting plate, and the wireless charging mechanism can then begin charging the phone.
[0029] This invention relates to a vehicle-mounted wireless charging device for mobile phones. It features a scientific design, reasonable structure, convenient manufacturing and maintenance, and an attractive appearance. All mechanisms are compatible and connected, and their movement and state do not interfere with each other.

[0050] When the in-vehicle wireless charging device of this invention wirelessly charges a mobile phone P, it generally goes through the following steps:
[0051] Step 1 – Release the chuck mechanism
[0052] In practical use, when it is necessary to wirelessly charge a mobile phone P using the in-vehicle wireless charging device of this invention, and the claw mechanism is in such a state as 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.
[0053] Step Two – Extend the Telescopic Mechanism
[0054] 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.
[0055] Step 3 – Start the charging mechanism
[0056] 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.
[0057] Step Four – Retracting the Telescopic Mechanism
[0058] 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.
[0059] Step 5 – Clamping the jaw mechanism
[0060] 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.
[0061] Step Six – Retrieving and Placing the Phone
[0062] 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.
