The circuit board 2 and the expansion housing 3 can be maintained by disassembling and assembling the base plate 12. The connection between the expansion housing 3 and the upper cover 11 is located in the opening slot 111, which improves the overall aesthetics of the wireless charging device. Specifically, the expansion power terminal 21 is located at the bottom of the circuit board 2. By setting the expansion power terminal 21 at the bottom of the circuit board 2, the operator can operate the electrical connection position between the functional device 4 and the circuit board 2 by disassembling the base plate 12.

[0043] In addition, the power supply terminal 22 is also located at the bottom of the circuit board 2. The operator can operate the electrical connection position between the wireless charging module and the circuit board 2 by disassembling the base plate 12.

Setting multiple power supply terminals 22 can provide power to multiple loads simultaneously or at different times, and can provide corresponding power connection methods according to the specific number or location of the wireless charging modules.

[0044] In this embodiment, the bottom of the expansion housing 3 is provided with a first wiring notch 36 that connects to its interior. The electrical connection wire of the functional device 4 passes through the first wiring notch 36 from the interior of the expansion housing 3 and is electrically connected to the expansion terminal 21. The first wiring notch 36 allows the electrical connection wire of the functional device 4 to pass through, avoiding interference between the wire and the expansion housing 3 and ensuring the stability of the electrical connection.

[0045] Preferably, the extended housing 3 is provided with a lifting mechanism, and the functional device 4 is installed in the lifting mechanism, so that the functional device 4 can be raised and lowered to meet different usage needs.

[0046] Please combine Figure 5 and Figure 6In this embodiment, the lifting mechanism is an electrically driven lifting mechanism, which includes a fixed bracket 32, an electric drive assembly, and a lifting bracket 35. The fixed bracket 32 ​​is installed inside the expansion housing 3, and the lifting bracket 35 is slidably installed on the expansion housing 3 along the height direction of the expansion housing 3. The functional device 4 is installed on the lifting bracket 35. The electric drive assembly connects the fixed bracket 32 ​​and the lifting bracket 35. The electric drive assembly is electrically connected to the circuit board 2 and is used to drive the lifting bracket 35 to rise and fall.

The inner circumference of the ratchet sleeve has mountain-shaped helical teeth, the sliding pawl is mounted on the lifting bracket and has claw teeth on its outer circumference, and a guide groove is provided at the bottom. The guide core is fixed inside the base and cooperates with the guide groove of the sliding pawl to restrict the degree of freedom other than rotation. The return spring is sleeved on the outside of the guide core and always pushes the sliding pawl upward. The ratchet sleeve is press-fitted or snap-fitted to the fixed bracket at the bottom of the expansion housing, and the guide core is mounted on the housing and located inside the expansion housing. The lower end of the return spring abuts against the bottom plate of the base, and the upper end abuts against the lower plane of the sliding pawl.

[0050] Working principle when the lifting mechanism is a push-to-jump manual lifting mechanism: 1. Static retracted position: The pawl teeth are engaged in the lower step of the ratchet sleeve, the reset spring is compressed and stored, and the functional components are fully retracted into the extended housing, resulting in a simple appearance.

[0051] 2. First press: The user presses down on the functional device, the sliding claw moves downward under force and makes circumferential steps along the helical teeth; after releasing the hand, the reset spring pushes the sliding claw upward, the claw teeth slide into the high step and are locked, and the functional device remains in the extended state.

[0052] 3. Second press: Press down again, the slider continues to move circumferentially and disengages from the high step; after releasing, the reset spring pushes the slider back to the low step, and the functional device retracts into the extended housing.

[0053] In summary, the wireless charging device provided by this utility model has mounting holes on the outer surface of the base for detachably mounting the expansion shell. Simultaneously, the circuit board is also detachably fixed to the mounting cavity of the base, and an expansion power terminal is provided on the circuit board for electrical connection with the functional components inside the expansion shell. Since both the expansion shell and the circuit board are independent and detachable modular components, the manufacturing process only requires selecting a matching circuit board according to the specific function of the functional components to complete the assembly. The base, wireless charging module, and other structures require no design changes, thus achieving functional expansion at the lowest cost.
